Asus ZenWiFi AX XT8 AX6600 Review: The Best Wireless AiMesh Set to Date

The ZenWiFi AX AX6600 Whole-Home Tri-band Mesh Wi-Fi 6 System (model XT8) is a souped-up version of the CT8. Both are part of the new ZenWiFi family Asus announced earlier this year.

The only differences between the two, albeit big ones, are that the XT8 features Wi-Fi 6 and a multi-gig WAN port. Other than that, they share everything else, the appearance, setup process, features, how they work as mesh systems, and even some shortcomings.

This review focuses on these differences. It’s intended for those who have already read my take on the CT8.

In all, compared to the CT8, the ZenWiFi AX XT8 has more than enough to justify the extra $100 you’d need to spend. Though not a must-have, it’s a reasonably-priced, flexible Wi-Fi 6 AiMesh system with a ton more to offer than its more expensive rivals.

Asus ZenWiFi AX XT8: Everything the CT8 has and a lot more

As a mesh system, the ZenWiFi AX, like the CT8, includes two identical routers. From the front, you can’t tell the hardware of the XT8 and the CT8 routers apart. The two look the same, sharing the single-slot-toaster design, and are available in white or charcoal colors.

Familiar design, now with Multi-Gig WAN support

On the back, though, you’ll note that the XT8’s WAN port is now a Multi-Gig port that works either at either 1Gbps or 2.5Gbps. Also, the USB 3.2 Gen 1 port is on the right side instead of the left.

Like the CT8, the XT8 features Dual-WAN — you can turn its USB port or another LAN port into a second WAN port if you want it to host two broadband connections at a time or load balancing or high availability.

Asus ZenWiFi AX vs ZenWiFi AC
The ZenWiFi AX XT8 and the ZenWiFi AC CT8. Look closely. Maybe you can tell them apart.

By default, there’s no Multi-Gig LAN port. And that’s disappointing since that means locally, the best wired-to-wireless connection you’d get out of the XT8 is 1Gbps.

But when working as a node, the XT8’s 2.5Gbps WAN port now works as a LAN port. However, generally, in real-world usage, it’s not a good idea to count on the wireless backhaul to reliably deliver the same speed as a wired Multi-Gig LAN connection.

Also, you’ll need to have a second node unit before you can see the value of this port. With a 2-pack, the speed is limited by the other Gigabit ports anyway.

High-speed backhaul band, presently no 160MHz channel support for clients

Each XT8 hardware unit is an AX6600 tri-band router with one 2.4GHz and two 5GHz broadcasters. The router dedicates one of the 5GHz bands, the 5GHz-2, as the dedicated backhaul, which works solely to link the two hardware units to form a mesh system.

The 5GHz-2 is the most powerful band, featuring 4×4 Wi-Fi 6 to deliver up to 4800Mbps. It also supports the venerable 160MHz channel width. Thanks to this strong backhaul connection, you can place the XT8’s hardware further from each other and still have a fast mesh system.

Read this  Wi-Fi 6 in Layman's Terms: Speed, Range, and More

The other 5GHz band (5GHz-1) uses 2×2 Wi-Fi specifications, generally caps 2400 Mbps for Wi-Fi 6. Unfortunately, however, the XT8’s front-haul doesn’t support 160MHz channels. As a result, Wi-Fi 6 clients can connect at 1200 Mbps at most in a wireless setup, while Wi-Fi 5 devices will get 867 Mbps.

Update: Asus told me on February 11, 2020, that it would might release a new firmware update that opens up the front-haul to support 4×4 160MHz specs, effectively doubling the XT8 satellite’s Wi-Fi speed for clients. This never turned out to be the case, however.

Many mesh routers don’t support 160MHz channel width for end-users. Examples of these include big-name products like the Ubiquiti Alien and the Netgear Orbi RBK 852.

ZenWiFi AX Web UI
The ZenWiFi AX XT8 shares the same web interface as that of previous Asus routers. Note its 5GHz-2 band’s default setting for the dedicated backhaul role.

Wired backhaul support

Like all AiMesh routers, the ZenWiFi AX support wired backhaul — you can use a network cable to hook one router to another.

In fact, if you have a Multi-Gig switch, it’s one of a few Asus broadcasters that supports Multi-Gig backhauls. But there might be a catch.

Extra: Important note on using wired backhaul

Since the XT8 is purposely built for a wireless setup, its firmware might not be tuned for a wired backhaul setup. As a result, a new firmware might cause issues if you use wired backhaul with it.

Generally, in my experience, if your (wired) network is stable, it’s a good idea not to upgrade the firmware right away but only after the subsequent version of the new version is available.

In other words, a new major upgrade tends to include issues that need to be ironed out by a minor version. If you’re aware of this, then it’s OK to use this mesh with wired backhauls.

In a wired backhaul setup, by default, the XT8’s 5GHz-2 band is still not available to clients — it remains a hidden dedicated backup backhaul in case the wired connection is lost.

So, when you use SmartConnect, this 5GHz-2 band is not part of the main Wi-Fi network. In short, it will not be available to clients at all.

There’s a way to make use of this band, however. You can manually create a new unhidden SSID with it, different from the primary Wi-Fi network. This SSID will then be available, throughout the AiMesh system, as separate 5GHz-only full 4×4 Wi-Fi 6 Wi-Fi network for clients.

In other words, like all tri-band AiMesh systems, with a wired or wireless backhaul, you’ll need to do a bit of tweaking to make the 5GHz-2 band available to clients.

Update: With the latest firmware that supports AiMesh 2.0, there’s now an option to combine all three bands via Smart Connect when the wired backhaul is in effect. So with the latest firmware, this mesh will (likely) function the way you’d like it to do with no catches. But this is not a sure thing.

Familiar settings, features, and shortcomings

Again, other than the more powerful hardware, the XT8 shares the same set of settings and features as the CT8. It also uses the same web interface and the Asus mobile app. That said, you can find out more in the review of the CT8, including how to set the system up.

To avoid repeating myself, I’ll recap below some significant points.

Asus ZenWiFi AX’s highlights

  • Out of the box, the two XT8 hardware units are pre synced. No matter how you change them individually — like using each as a standalone router for a different home — once restored to default settings, they are ready to work together as a mesh.
  • The XT8 router can work with all other AiMesh-enabled routers, as the router unit or a satellite node.
  • You can restore the XT8 router with the settings of any previous Asus router, making upgrade an easy job. Note, though, that it’s always better to set it up from scratch to avoid potential setting conflicts
  • The XT8 can work as a node for a system hosted by any other AiMesh-ready router. Or it can host one to extend its own network.
  • There are lots of network settings, enough to make almost any advanced user happy and features anyone would appreciate. These include AiProtection (online protection and parental control), Traffic Analyser, Adaptive QoS, VPN (client or server), and an excellent Dynamic DNS.
  • AiMesh now has a new section of its own, within the web interface, which makes managing and adding additional nodes easier. You can also make use of the XT8’s USB port even when it’s working as a node.
  • The USB port can do all that you can think of for a router peripheral port. You can use it to host a printer, a cellular modem, or a storage device to deliver all storage-related features you can imagine — data sharing/syncing/streaming, Time Machine backup, PC-less downloading, and more.

Asus ZenWiFi AX’s shortcomings

And like other Asus routers, the XT8 shares the same shortcomings, too. First and foremost is the fact it can be buggy. Due to the sheer amount of features and settings, it seems Asus has had trouble keeping tabs on them all.

For example, a firmware update can cause issues — you might need to reset the system and set it up or restore settings from a backup file to fix it. Like the case of other AiMesh routers, the Guest networking feature was only available at the router unit and not throughout the system during my trial.

(For the latest on AiMesh, check out this frequently updated post.)

On top of that, make sure you understand the inherent risks of using the DFS channels, which is the only option to make the router’s 5GHz-band work in the 160MHz channel. Hint: Turn this off if you want to make sure your connection is stable.

Other than DFS-related issues, you can expect most of the system’s shortcomings to be addressed one way or another via future firmware updates. However, the excessive amount of settings can be overwhelming for home users and might cause the system to remain buggy in some shape or form.

ZenWiFi AX XT8: Excellent performance

For the official scores, I tested the ZenWiFi AX in a wireless setup. The system doesn’t have the Wi-Fi specs to be the fastest on the market. Instead, it delivers extensive Wi-Fi coverage and still with excellent real-world throughputs.

Read this  The Right Way To Do an Internet or Wi-Fi Speed Test

I used both 2×2 Wi-Fi 6 and top Wi-Fi 5 clients for the testing. Keep in mind that the XT8 is a 2×2 system of both standards from the clients’ perspective.

Fast Wi-Fi speeds

As a mesh router, the XT8 delivered precisely the kind of performance I had expected from it — hardware without Multi-Gig LAN or 160MHz channel width support.

(The router will deliver better Wi-Fi performance when you use it as a standalone device or open the 5GHz-2 band to clients.)

My Wi-Fi 6 client connected at 1.2Gbps and had a sustained speed of almost 840 Mbps at the close range of fewer than 10 feet (3 m).

XT8 Router

When I increased the distance to 40 feet (12 m), it registered higher than 770 Mbps. Wi-Fi 5 clients fared the worst on the chart. However, that’s because the XT8 is the only one among the existing handful of Wi-Fi 6 mesh systems on the market that doesn’t feature 3×3 or faster Wi-Fi 5.

That said, its scores of some 660 Mbps and 450 Mbps for close and long-range, respectively, weren’t bad at all.

The XT8 did it best when working as a mesh. The node (satellite) unit delivered the best performance to Wi-Fi 6 clients, averaging 850 Mbps and 792 Mbps for close and long-range, respectively. These were faster than higher-specced systems.

XT8 Satellite

Excellent range, reliable signals

With two units, the XT8 could cover anywhere between 4000 ft² (372 m²) to 5000 ft² of residential space in my testing with fast Wi-Fi speeds.

I tested the system with the node placed some 40 feet away. But in anecdotal tests, I could put it some 70 feet away and still get speed fast enough to deliver my 300 Mbps internet in full.

Your mileage will vary, but it’s safe to say, thanks to the full 4×4 Wi-Fi 6 backhaul, in a wireless setup, the XT8’s range delivers. The system proved to be reliable, too. It passed my 3-day stress test without any disconnection.

Real Wi-Fi 6 speed with wired backhaul

The XT8’s wired backhaul also worked well in my trial — in this case, the distance between the two units doesn’t matter much. I created a separate network with the 5GHz-2 band and was able to get full 2400 Mbps connection speed from it using my 2×2 Wi-Fi 6 clients.

Note, though, that this connection speed was between the clients and the XT8. So, the only time you truly benefit from the Multi-Gig Wi-Fi speeds is when you have a Multi-Gig WAN connection and the clients connect directly to the router. Since the XT8 has no Multi-Gig LAN port, clients connected to the node won’t get real-world speeds faster than 1Gbps.

Still, it’s nice to have the option to have a 5GHz band working for high-speed clients. That said, even though not necessary, it’s a good idea to use a network cable to connect the two hardware units.

Decent performance as a mini-NAS server

Without a Multi-Gig LAN port, the ZenWiFi AC XT8 can’t compare to those with one in terms of network-attached storage performance when hosting an external drive. But it was much faster than the CT8 in my testing.

Asus ZenWiFi AX NAS

When coupled with the SanDisk Extreme portable SSD, via a Gigabit connection, the router scored 46 MB/s and almost 65 MB/s for writing and reading, respectively.

These numbers are decent enough for casual network storage sharing, but you should think of a real NAS server if you want to do more.


The ZenWiFi AX XT8 AX6600 Whole-Home Tri-band Mesh Wi-Fi 6 System is one out of more than a dozen Asus AiMesh systems I’ve tested, and it’s one of the best, if not the best.

The system is far from perfect, though. It’s not the fastest, nor does it deliver all features you can get from an Asus router — it has no game-specific features or Multi-Gig LAN port. And like most Asus routers, it can be buggy, too. You might need to work at it for a bit before it works for you.

In return, it has an excellent combination of everything you’d look for in a mesh Wi-Fi system, which is fast performance and broad coverage. There’s hope that it only gets better via firmware updates.

Most importantly, at less than $450, it’s a steal. Many other 2-pack mesh systems on the market, like the Netgear Orbi RBK852 or the Arris SURFboard mAX Pro, cost hundreds of dollars more yet have less in features and network customization.

  1. Appreciate the super detailed review. Any idea how to account for the lackluster NAS performance compared to other Asus routers with similar specs that also lack a multi-gig LAN port?

    For example, your NAS tests show the RT-AX92U and RT-AX88U as having nearly double the read/write throughput. Spec-wise, I don’t see significant difference, and the AX92U in particular is only dual-core versus the quad-core here, so in theory the CPU power should not be the limiter.

    I much prefer the “white box” form factor of having the antennas integrated, but these NAS specs are concerning. Might a firmware update resolve this, or is it somehow attributable to the hardware?

  2. Hi Dong
    I would really appreciate it if you could help me on this.
    I wonder if my AX3000 could work well as a wired router together with my xt8’s acting as 2,5gig AP’s (with a multigig switch off course)?

    Or would i be better of with the same or higher specced hardware like the xt8’s for routing?

    Would turning off the 58u’s broadcaster (using it as a wired router) lighten it’s cpu load, freeing up memory, making it do routing better?


      • Thank you for replying Dong.
        Is it the use of the lower specced ax3000 as wired router you do not agree on?
        I thought that highest spec hw first mostly applied to mesh networks.
        I thought that it going dark would free up some cpu and ram, compensating for lacking hw.

        Also one big reason i would still want to use the 3000 as a “wired” router is the AI-protection that comes with the router.

  3. Hi Dong,
    First of all, THANK you for your work and detailed explanations!

    I would need your expertise and help in order to buy the appropriate equipment for our future home that will be ready in a few months (by the way, I live in the south of France).
    Our house is 140 square meters (that’s about 1500 feet) and it has 2 floors with a total number of 4 bedrooms (ground floor has 75 square meters and 65 square meters for the 1st floor)
    After carefully reading your post, I believe the ASUS ZenWiFi XT8 system is what I need for my home but I am afraid it is not enough to cover my backyard as well.
    As far as I understood, I can’t add a 3rd standalone unit or even a second ASUS ZenWiFi XT8 to have 4 nodes in total (also i guess this option would be a bit overkill).
    My idea is to use an Assus host router and to connect the ASUS ZenWiFi XT8 to it as 2 nodes.
    That way I can put the host router in the middle of the house to cover the wireless gate door bell outside the house , one of the ASUS ZenWiFi XT8 (first node) close to the exit on my back yard and the 2nd ASUS ZenWiFi XT8 upstairs to cover the 3 bedrooms I have there.

    My question is: which Assus host router to buy? I believe I need a tri-band wifi6E.
    I was thinking of ASUS GT-AX11000 (it costs 469 euros here in France) but it’s a bit expensive and I am not sure I really need to pay that much, maybe there is a better alternative.
    This router will be connected via ethernet cable to my ISP provider box that will be situated in my garage (i have 1Gbit fiber optics).

    Can you help me with this? Can you give me one or 2 more models from Assus that are cheaper but enough to hold my 25-30 overall devices I have at home (tablets, phones, pcs, door cameras, outside wifi cameras etc).

    Thank you in advance for your reply,
    Sorin from France 🙂

  4. Dong,

    There is a known issue regarding wi-fi upload speeds with this. Can you add wi-fi upload speeds to your tests?

  5. Hi Dong, I’ve read many of your comments and posts about xt8 vs xd6 and which scenario to use which.

    If I’m going to use wired backhaul, given that the xt8 firmware has been updated to allow the previously dedicated 160mhz / 5ghz-2 backhaul to be used on fronthaul, would you still suggest I use the xd6? Or can the xt8 on wired backhaul be used now too with similar results?

      • Thanks Dong! My only issue with the XD6 is that I need aUSB port, which the XD6 doesn’t have but the XT8 does. Is there any way I can configure the XT8 to operate as much as possible like an XD6? e.g. the new firmware of the XT8 allows me to use the 5ghz-2, so am I able to ‘disable’ the 5ghz-1 band on the XT8 when using wired backhaul so I effectively have the same channel-widths as the XD6? Thereby giving myself a XT8-come-XD6 but with a USB port? or am I missing something / making my life more difficult? Is there any other solution if I want a mesh system with a wired backhaul with USB port?

        (thanks for your great content)

          • Cool thanks Dong. I might go for the Asus RT-AX86U as router and XD6 as nodes. One question on this setup though – I notice the AX86U runs 2.4ghz in 3×3, whereas the XD6 runs 2.4ghz in 2×2. Any issues with that – or good to go ahead?

          • That won’t matter, Sameer. That band is going to be slow, by the way, just how it is.

  6. Hello Dong, thank you for your great website.

    I have AX11000 as the main router and 3 x XT8s as wireless APs. One of the issues I have is that they keep ignoring my specified topology, ie Preferred WiFi Uplink AP setting – I’ve tried both and 386 rc3-3 firmware to no avail, do you know how to force them to stick to the right setting?

    Also, many devices – both IOTs and Macs – choose their AP very weirdly, ie definitely not the closest one/the one with the strongest signal, what can be causing that?

    Many thanks.

    • Check out this post on the handoff, Alex. But the gist is Wi-Fi doesn’t work the way you “see” things, since it’s indivisible, to begin with. In your case, just click on the Optimization button in the AiMesh section of the web interface and let the system does its things. (Also, don’t use the mobile app, or use it but don’t trust what you see.)

      As for your IoTs, Id’ recommend separating the bands, or creating an extra SSID via the Guest network (you can enable the intranet access for it to work as a non-Guest network — more in this post.)

  7. Hi Dong,

    My house is 3000sq ft and two stories. Currently, I have 600 mbps download blaze plan from xfinity and I use Netgear C6300. I wasn’t getting enough speed or connection hence decided to buy mesh wifi and after reading tons of reviews online, I bought this Asus AX6600.

    My question is do I need to buy another modem with 3.1 or can I continue using the current Netgear C6300?

    Second question, is it going to be overkill for 600mbps speed. Should I switch to gigabyte plan?

    I really appreciate your help in advance. Thank you!

  8. Thanks for all the help. My XT8 keeps loosing wifi broadcast. I have to power down and power up the node to get wifi again. Happens multiple times a day – sometimes every 10 minutes. Up to date on firmware. Please help.

    • What I realized today after I replied back to Dong is that I wasn’t selecting the backhaul band so I could then modify the settings (see below reply to my comment on Dec 15 2021 where he links to the post that discusses DFS).

      You need to go to Wireless->General->Band and then select the “5Ghz– 2 ” band from the drop-down box – this is the backhaul band. When you select this, then you’re able uncheck “Enable 160 MHz” under Channel bandwidth as well as select a Control Channel that is outside the DFS range.

      ‘ll know in a few consecutive days if this has resolved the issue as my disconnect issues with my XT8 have been occurring every 24 to 36 hours.

  9. Hi Dong, were you able to find out how many concurrent client connections each access point could support?


  10. Hi Dong,
    I purchased the XT8 about 6 weeks ago and have had some trouble with it. I’m using ethernet backhaul with both units connected. My speeds are actually very good. HOWEVER, I’m experiencing a very annoying issue: at random times, the units will disconnect briefly for a minute — not a full reboot, but one which causes my WiFi devices to disconnect and reconnect. Imagine all the notifications from smart home devices warning of a WiFi interruption, as well as audio and video buffering.

    I’ve raised this issue to ASUS but they haven’t offered a solution yet (they suggested changes to various settings like channel bandwidth, control channel, WAN DHCP query and LAN Switch Control, but nothing worked). In fact, I recently exchanged the units and still having the same issues with the replacement units.

    Do you think it’s their firmware? I’m on their latest update.

      • Thank you, Dong, for the quick reply! After reading this, I think perhaps you may be right, which is why ASUS did advise me to make some changes to the Channel Bandwidth and Control Channel settings for each band. And yes, I reside pretty close to a large airport and military installation, so this might explain the root of the problem with WiFi 6. Hopefully I can do some further fine tuning to these settings (a nice feature of ASUS’ router management vs. other manufacturers). In any case, I really appreciate your detailed explanation.

          • Hi, again,
            So, per your article on the DFS issue, after modifying these settings (I’m using channel 36 on my 5Ghz band) I’m still experiencing the problem. Not any worse, but not any better. And ASUS has not offered me any further solutions.

            Is just something I’m going to have to tolerate with WiFi 6 routers like this — and in particular this XT8 one?

          • It’s not the channel number, Jamie. You need to disable the 160MHz channel width on the backhaul band. The first screenshot in this post is shown with that turned on. You need to uncheck the box, save the changes, and restart your router. Take your time, pay a bit of attention, and you’ll get it right.

          • So after figuring out how to get to the backhaul band and modify its settings (btw it appears the web interface has changed slightly since your original post with the screenshot), I was able to follow your instructions to disable the 160 MHz channel width and then set a control channel outside of DFS. Surprisingly and unfortunately, the WiFi disconnect issue is still present and actually more frequent now (has happened twice in the last 24 hours vs. perhaps once every 24 to 36 hours).

            I appreciate that you aren’t ASUS tech support, but I’ve gotten nowhere with them, so just wondering if you have other advice — including how to address this with ASUS. Because this keeps happening, I’m quite disappointed in this XT8 system and may be looking at returning it for an alternative. This is my second set of the XT8 as I had experienced the same issue with the first set (I exchanged it for this 2nd set thinking the first was defective).

            Thanks in advance!

          • I’d recommend resetting it and setting it up again, Jaime. Now, disable the 160MHz on the backhaul, and that’s it, leave the rest alone and see how it pans out. You might have changed so many settings that you don’t even know what causes the issue anymore. Don’t use the mobile app, by the way! Also, make sure the disconnection issue is not Internet-related, it could be your modem or your provider. It’s impossible for me or anyone outside of your home to know. For more, check out this post on troubleshooting.

          • Well, Dong, I followed your advice exactly (did a full factory reset and unchecked both “Enable 160 Mhz” and “Auto Select channel including DFS channels”). Unfortunately this has failed to resolve the disconnect issue I originally asked you about. I wanted to wait a couple of weeks to see if things improved before asking you for more advice.

            One thing that happens when I apply the above settings is that the “Auto Select channel…” option goes back to being checked. Nothing I do stops this from happening.

            Anyway… given that I have wired my house (YAY!) and thus have both my nodes connected by Ethernet, I’m wondering if exchanging the XT8 for the XD6 would resolve my DFS problems.

            On the other hand, I *could* tolerate this issue…while it is mildly disruptive, it is not what I expected with a top-tier WiFi 6 router like the XT8.

            Thoughts? Other ideas? Thanks again — I would have been totally lost without your posts!!!

          • You shouldn’t have gotten this set if your home is wired. Remember that I answer questions assuming folks have read the post with attention. Maybe you should do that first. For your case, you have plenty of options, more in this post. If you want to keep the XT8, revert it back to an older firmware — *READ* this review for more.

  11. Hi Dong,
    Thanks for the reviews. I recently bought Asus xt8 (2-pack) and replaced the Linksys Velop AC6600 (3-pack).

    My home is a two storey house, and about 3000 sqft including basement. Since there is only a few minor devices in the basement, I put one XT8 on the main floor and the other one on the second. Two routers are connected wirelessly, and my PC connects to the node on 2nd floor by wifi. I did get faster speed according to speedtest.net. My internet plan is 1000 and I am getting around 500 on my PC(wifi 6 client) instead of 200-300 from the old Linksys setup. I noticed that the speedtest.net now takes very long time(more than 5s) to connect after clicking go, but turns out the ping is low.

    I found that some websites is slower than before. It would take a 2-3 seconds to start loading depends on the websites, and some video website(YouTube etc) takes longer time(5s or longer) to be completely loaded(video thumbnails are blank at first and load slowly after). But this doesn’t always happen, sometimes they work well.

    Also, I found some of my smart home devices disconnect sometimes. My hue app occasionally stuck at connecting. And my nest cameras take longer time to watch real time, and sometimes lagging when apply settings. None of these happened when I was using Linksys.

    When it comes to gaming and downloading, it’s a great improvement over the Linksys. The download speed is much faster and the ping in game is lower.

    I am wondering what could cause the problems. I did not use any QoS setting. I tested packet loss and jitters, and the result seems fine. Is this a ‘stability’ issue? What can I do to resolve this? Will it help if I add an Asus Gt-Ax11000 as the main router? Or should I buy Linksys MX12600 instead?

    Thank you for time!

  12. Hello Dong,

    I am looking at getting a mesh system for our house, and I have narrowed down the choices to either the ASUS ZenWifi XT8 or the TP-Link Deco X5700. I like the features that the XT8 offers, but the performance numbers for the X5700, based on your chart, are very hard to ignore (Router Performance of 1436.24/1116.24 Mbps for the X5700 vs 835.6/792.1 Mbps for the XT8). Since the XT8 was tested before the release of AiMesh 2.0 and the Smart Connect feature, would that improve the performance numbers for the XT8 in a wired backhaul setup? For reference, I currently have Xfinity Gigabit internet service, and a Motorola MB8611 DOCSIS 3.1 cable modem.


    • Here’s how I test Wi-Fi , Jamison. If you read that post and check out the text of the reviews, you’d know the reason for the big differences in the performance numbers and how they don’t mean much.

  13. Hi Dong. First time I have seen your reviews. They are great, detailed and easy to understand for a noob like me. I live in Melb, Aus. I have a long house, with one area (a rumpus room) downstairs at the back of the house. Brick veneer house with timber stud/plaster walls. My max speed is 250Mbps. My house has been wired so I can connect satellites via ethernet at each end of the house and in the middle if need be. Areas needed for wifi would be more at front and rear of house. I have some devices that need to connect at 2.4 I currently dont have any wifi6 devices but in the future I suppose they will come. Is there any advantage at all to get tri band or is it just wasted because I will be wired. Which unit should I go for? Thanks for your help.

      • Thanks Dong. Not sure what to look at here. Is there a need to get a different router, say the RT-AX86U, and a pair of XD6? Or could I just do with a pair (or 3) of XD6? And if I went with the XD6, could I add the RT-AX86U later if I felt I needed to?

        • You need to read the entire post and pay attention, Adrian. Sorry but I’m not going to address questions that have been addressed.

          • Thanks, but I am fairly tech illiterate. I’m not sure why a different router would be an advantage rather than just having 2 x XD6’s.
            Also, with the XD6, can you tell me if I have the option of selecting the 2.4 band for individual devices that need to connect to 2.4?

      • Hi Dong,
        Currently I am using Ax86u as aimesh router and two of Ax58u as aimesh nodes. I get my house wired and use ethernet backhaul. Should I switch from this combo to 3 packs of XT8?

        PS: are you Vietnamese?

  14. Hi Dong,

    Thanks for the excellent reviews and I’m sorry if this is repetitive.

    I’m looking for a 2 pack mesh wifi, RT-AX92U in a 2-pack is $330 while the XT8 is $430. I do not see any reason to choose the XT8 over the RT-AX92U model at this price if I’ll wired backhaul.
    Both models will have the same performance if wired backhaul, however RT-AX92U has broader coverage, 2 USBs and is cheaper.

    Am I missing something?


  15. Thank you for an excellent review, can you confirm if this system allows for a second satellite to be connected? I would have thought this was the case, and I think you are saying this is correct in other comments, but I’ve read elsewhere that it’s limited to 2 units only?

  16. Hi Mr. I read and read and hands down your are the best.
    Sorry about my bad English, is not my primary language.
    I am seriously thinking about changing the Mesh that I currently have in the house/office (Google WiFi using a central point plus 3 satellites. It is OK, but in some places I only have some as 40mbps from my 200mbps internet connection in FiberHome, I think about a NETGEAR Powerline adapter Kit PLP2000-100PAS for one of the hubs, but not sure if it can reach 100 or more mbps at all). Unfortunately I cannot make wired connections, so I must only use wireless connections between the hubs.
    My incoming connection have 3 internet providers, FiberHome at 200mbps, and two WISP at 20mbps and 15mbps, all comes to a Ubiquiti EdgeRouter PoE (5 ports) in a configuration that if my 200 connection is up is the only one used, in case of drop the two WISP come in a load balance scenario (for my job I need a 7×24 connection).
    I’m thinking about the Asus ZenWiFi AX (XT8) (maybe?) in a 1 + 3 configuration (1 primary and 3 satellites/hubs) , most because the house is big and is full concrete and bricks, extra to that is not a square and 3 floors in total.
    There are basic factors that I need/interest me:
    1. Ease and convenience to configure (control from my iPhone etc), but that have some pro features that I miss in my Google WiFi)
    2. A guest network, if I can limit it in terms of how much bandwidth it provides to guest better
    3. If possible to define bandwidth limits to certain equipment’s connected is a BIG plus
    4. Statistics of use and speed test of the provider
    5. That I can see ho is connected and how much is using the bandwith
    6. That can be accessed from outside the house if necessary (remote control or something like that)
    7. That does not require rare subscriptions to pay every month or yearly
    8. And before my wife kills me, be “decorative” or not visible (big advantage from the Google Wifi, small and can be hidden easy), but I know, nothing is perfect
    Some friends talk me about the Unifi Alien, but after read a lot I don’t think it is the best option, so I return to the Asus as option
    Any advice and is possible to do all that I like to do with the Asus XT8?
    Thanks in advance, regards

  17. Dong,

    Can the Asus AX XT8 be used in Access Point mode instead of a router?

    I have a situation where I can’t replace the router but I want to replace the routers wifi functionality with a better option and also a mesh system.

  18. Hi Dong. I had a pair of CT8 set up with wired backhaul. One of those units died. I returned it for warranty repair and in the meantime I purchased another pair of CT8. I have one node in the basement and the third unit in a detached garage, both with wired backhaul. ASUS was unable to repair my defective CT8 due to parts availability and did not have a replacement available either. They offered to replace it with an XT8 which I accepted. My question is whether there would be any real advantage to using the XT8 as my main router. My current system is working well and I have no WiFi 6 devices at this time. Cell phone upgrade coming soon so it may be WiFi 6 capable. I think I read in one of your articles that it was not good to mix these two if using wireless backhaul but what about when they are hardwired? Or better to leave my setup as is? Thanks for your great testing and articles.

      • I read that again and this is the part I was asking about: “Sometimes, you want to mix a router with the best feature set with a more affordable node. Of course, in this case, you’ll get the Wi-Fi performance at each mesh unit according to their hardware specs.

        Again, if you use wired backhaul, there’s not much concern here. But if you think of a wireless mesh, it’s best to use routers of the same Wi-Fi standard (Wi-Fi 5 or Wi-Fi 6) and performance tiers for better reliability.”

        I am using ethernet backhaul to both locations. I will probably turn off wireless backhaul and run 5Gz 2 on a separate SSID. Still a bad idea or nothing to be gained doing this? Sorry if I misinterpreted something. Thanks.

          • Sure, Scott. I think I missed the part you mentioned wired backhaul — I only have so much time for each comment :). With that you have a lot of options, worse comes to worst, you can always use the CT8 in the AP mode. Good luck! The XT8 is a much better router.

  19. Hello,

    I opened the 5Ghz-2 giving the same SSID as the 5Ghz-1. It seems to work, but maybe this method is not recommended?

  20. Hi Dong,

    Great review. I just purchased Asus XT8; however, I realize that there is a restriction in my country that all 5ghz band is only allowed at Ch 149+, which is only available 5ghz-2 (iPhone could not detect the wifi on channel 36-44). So is there any way to swap around the dedicated backhaul to 5ghz 1 instead of 2? or open more channels on 5ghz1? If none of the options are available, would it be ok for some devices to join the dedicated backhaul SSID while keeping the 5ghz2 dedicated for backhaul?

    Thanks for the help

    • Your best bet is opening up the 5GHz-2 band for clients, Allen, as I mentioned in the review. And that means it’s no longer “dedicated”. In your case, there’s no benefit in getting tri-band hardware at all.

  21. Hi sir,

    Thanks for all the valuable info on this mesh system. On your advice I purchased this about 18 months ago and it has been pretty solid and stable….until today which I can’t figure out for the life of me. I have the main unit in my basement connected to my modem and then one node upstairs connected via wifi. Wifi works great everywhere in the house. IThe problem is i can’t maintain a ethernet connection for devices plugged into the main unit. For example, When I connect my laptop directly to the main unit via ethernet, it works. However when I connect another device to the main unit via Ethernet it won’t connect and also I lose connectivity to my laptop. Once I unplug both devices, then plug the laptop back in, it connects right away. Its almost like the asus will only allow one IP via Ethernet or something. At the mesh node upstairs, like I mentioned, i have that connected via wifi, but there is an IP camera connected via Ethernet, and it functions properly. What brought this all to my attention is that all the devices that were attached via ethernet to my network switch(which is connected to the main asus in basement) like 3 tvs in my basement, all lost their connection today. I have unplugged that network switch from main router so I’ve taken that part out of the equation to try to make troubleshooting easier. If I didn’t explain well enough, please let me know and I will fill in the blanks. I have tried all the simple steps like power cycling the cable modem and ASUS router, unplugging cables and such. Its just seems like the main ASUS unit will only allow one device to connect to it via Ethernet therefore making any other devices unable to connect as well as my switch. Any suggestions please. Thanks in advance! I appreciate it!

  22. Hey Dong!

    Huge fan of yours! Is it possible for me to connect the XT8 straight to the modem, or does it have to go through a router? I was recommended the AX88U as the router/switch to connect to the LAN points, and have the XT8 run through wired backhaul. Is this a good setup?

    Thanks in advance!

      • Hi Dong,

        Thanks so much for the reply! I have 8 network cables at my modem point I need to connect to run wired connections in my house. Can I run this setup:

        Modem > Switch > Network Cable A > Network Cable B > XT8?

        Thank you again!

  23. Dong,

    First, thank you so much for all of the work you put into this website. It is by far and away the biggest wealth of knowledge I’ve found on the entire internet as far as explaining the ins and outs of all the newest networking technologies.

    I am currently using a Linksys MR9000 Max-Stream AC3000 Tri-Band Mesh WiFi 5 Router along with a Linksys Velop Intelligent Mesh WiFi System, Tri-Band, 3-Pack (AC2200). I’ve got the MR9000 connected to my router and acting as the main router. Then I have the three Velop units setup as wireless nodes.

    After reading a LOT of info on your page, I am feeling like this system SHOULD be working a LOT better than what I’m experiencing. I have been considering changing over to one of the new WiFi 6 systems such as the ASUS ZenWifi XT8 (2 pack) or a Netgear Orbi RBK852 system with 1 extender (2 total units) but I’m not really sure if I will even feel like we have upgraded or not.

    We have a 4 bedroom house that is about 3,400 sq ft but unfortunately, the main modem and router has to be in the office that is on one end of the house. No possibility of having it in the center of the house. I’m sure that would make a HUGE difference but I have to work around that. And the biggest issue we’re having is that it seems like the number of devices we are using at any one time is overloading the system. We currently have about 50-60 devices connected at any given time. If one of the nodes goes down. We notice it.

    Does WiFi 6 handle more devices so much better that it would help fix my issues by upgrading? Or is there a way to tune my current setup to handle them more efficiently?

    Would I be better off spending my money on a REALLY good Nighthawk router that could cover my whole home and stop using the additional nodes for now? Such as the RAX120 or the RAX200?

    Also, I’ve had a lot of trouble trying to decide whether to keep the three bands combined or going with them separated. Some of our devices don’t want to work with them combined but the overall performance seems better when they are combined otherwise.

    And one final thing to add to the equation. We probably screwed up big time with this but we got the Circle Home Plus device thinking it would be the answer to easily deal with having 4 kids and all of their devices but it has been a nightmare to setup and make work with the Velop system. We’ve ended up going with the app version only and leaving the hardware out of the equation completely because of how badly it slows down the network speeds. We like the app and how it works but it won’t help you with things like PS4’s and other devices unless you have the hardware in place. I now see that some of the Netgear devices come with the Circle Parental Controls built-in. Would going that direction with a WiFi 6 system solve those issues? Or should we be able to get the Circle Home Plus device we already have working with the ASUS system?

    I probably seem like I’m just out to spend money on WiFi devices. I’m not. I just want our network to work and currently I feel like I have more than I need and it still isn’t working the way I’d hoped.

    Any help you can offer about ANY of this mess is greatly appreciated.

  24. Hi Dong,

    Thanks for all the great info you’ve provided.

    I do have my home wired in the main but will ‘potentially’ want to place a node where it would need to use WiFi and I like the option of being able to utilise the additional 5GHz band if I do go fully wired for the backhaul. With that in mind I have boiled it down to the Asus AX AT8 or the TP-Link Deco X90 (X5700 not available it seems in UK). Of those two which would you steer towards?


  25. Hi Dong,

    Thanks for all your great reviews and taking the time to respond to all questions.

    Based on your review I am considereing to swap my Netgear R8000 + multiple EX8000 mesh extenders for a couple of Asus XT8.

    Reason being that in my fairly large house (thick concrete walls and floorts) I need several extenders, a setup which simply does not work reliably with these Netgear boxes. Connections drop all the time. Roaming from extender to extender does not work seamlessly either.

    Netgear mesh extenders can only connect to the router, not to eachother, which means the remote parts of my house will never get decent coverage.

    Can you confirm whether the Asus XT8 would works in a setup with a router plus 3 to 4 satellites?

    Does Asus support satellite to satellite to router connects?

    • I only answer questions that have not yet been addressed, Han.

      You can use multiple XT8 units (up to 7 in total, I believe, including the router unit), but using a wireless mesh with a daisy-chain setup is never good, though chances are the XT8 will be better than what you have now. You should consider getting the place wired.

      • Thanks for pointing me towards the daisy-chain part, I somehow missed that. I understand that it is not optimal, but there is no way I can reach part of my house without it – it is on the other side of the street. I have no means of getting a cable across the street, and the router itself is too far away.

        So it is either suboptimal daisy chaining, or stick to using a 4G modem there (which is more stable, but expensive).

        If you have any other suggestions then please let me know!

        • One more question. I could get the main house wired but not the annex across the street, that connection would always be wireless.

          Would such a hybrid solution work at all? Or will the satellite try to connect to a dedicated wireless backhaul (which is switched off in the rest of the house)?

        • If you can’t run wires then using wireless is the only way, Han. In that case, tri-band hardware will help, but the performance will always be fluctuating.

          • Just tested this with a setup of 4 Asus XT8s. I can confirm that they automatically switch to daisy chain (when needed) and that works just fine.

            As you pointed out, performance does drop but I am still getting around 80 Mbps (in the annex across the road), so I am very happy.

            Stability has been excellent so far, and the UI is so much better than Netgear. Thanks again!

          • For the nodes, you can try to select the “preferred wifi up-link AP”, this will ensure that the nodes always connect to AP.

          • Excellent! Thanks for sharing the result, Han. And I second what Sunny said, though the success rate depends on the placements, of course.

  26. Thanks much for your extensive notes on troubleshooting Wi-Fi dropout issues. I’ve been using my pair of Asus ZenWiFi AX XT8 units for a year. Initial performance was very solid. Very few dropouts. But of late, I’m seeing more and more dropouts. I’m starting to suspect a defective ZenWiFi master unit. Is there a simple way to replace the master unit with the slave/remote mesh unit to help trouble shoot this?

    I’m seeing frequent drop outs on both the 2.4 GHz and 5 GHz channels. And am seeing the issue with several different brands of IOT devices (Lenova, Honeywell, Google). I currently have four devices, across both channel frequencies, with connect time of under 10 minutes.

    I’ve gone through your extensive set of notes on how to fix WiFi drops, but that has not resolved the problem.

    One of the Lenova units is located within 5 feet of the mesh master station. And has typical connect time of under 10 minutes. It is set for 5 GHz operation. My Wi-Fi analyzer tool shows multiple signals at 2.4 GHz, but very little at 5 GHz.

    I’ve tried powering off the slave unit, and running solely with the master. That did not resolve the issue. I was next thinking of replacing the master unit with the slave unit, but was unsure how to do that.

    Very much appreciate any trouble shooting suggestions.

    • Yes, Arthur, you can back up the router unit, remove the node, reset the router, then restore the settings to the node, then add the former router as a node.

      • Dong, thanks for the suggestion of back up and restore to do the transfer to my second XT8 unit.

        When I recently tried to do back up of the XT8 settings using my Windows 10 PC, I got a message ‘‘Settings_ZenWiFi AX.CFG was blocked because this type of file can harm your computer.’

        This may be a Windows 10 change. I have successfully done backups in the past. I’ve asked ASUS tech support for a work around, but they have not yet responded. Net result, I’m not able to create a back up.

        • You need to actively let the browser save the file, Arthur — take your time and figure that out. That file is safe. If you don’t know how to do that on the current browser, use a different browser. If you don’t know what a browser is, well, I don’t think you can do what I suggested. This is like you’re asking me to help you troubleshoot a car, but you don’t know what a steering wheel is. And I’m not good at teaching folks how to use a computer. 🙂

    • I also had a lot of drop trouble with IOT devices, mainly Tasmota (ESP32) and Shelly. Setting static IP addresses did not help. Google’s devices actually retain the connection well.
      Eventually I just gave up. I added an old TP-Link Access Point as an IOT-only network, with a different band and name, and connected it to the Asus by Ethernet. Did not experience a single drop since.

      • Dror, thanks for suggestion to move high dropout devices to another router. That worked.

        I would agree with you that different designs show a quite different dropout performance. The devices I was having the worst dropout issues with were four Lenovo clocks. I moved three of the clocks to an older ASUS RT-N66U. Connect time went from minutes to 7-9 hours. I’ve left the Honeywell and Google Home devices on the XT8. I’ve seen recent uptime with the Google devices of 18-51 hours, Honeywell 1-8 hours. The one Lenovo clock I left on the XT8 continues to show poor connect time.

        Before turning on the RT-N66U, I did swap the XT8 Master and Slave units. That swap did not solve the issue of frequent Lenovo dropouts.

  27. Hi Dong, great review of the product!

    I have some questions about this router and hope that you can help me.

    1) I am planning to buy it, in a pair mode. I noted in your review, you mentioned that XT8 can turn one of the Gigabit LAN ports into second WAN port. I would like to ask, can I turn the 2.5G WAN port to become a LAN port and has it connect with my NAS (running at 2.5G port too) and turn one of the Gigabit LAN port to WAN port for internet use (my internet is 1Gb speed)?

    2) I will be placing the other unit as node in another room, and use a 2.5G switch to connect with the node’s 2.5G WAN port (by right it will be functioned as LAN port now), and wired connect to 2 PCs (both with 2.5G port). Will this setup giving more stable connection rather than to connect as WIFI directly? Most importantly, it’s about the file transfer speed from my NAS to PC. Due to some limitation, I was unable to use wire in the other room, so I came out this idea.

    3) From your review, I still not so understand about the 3rd 5Ghz setup (4800Mbps). Will this 3rd 5Ghz wifi connection comes out automatically? Also, is XT8 (router and node) using the 4800Mpbs speed to connect with each other? Can my PC connect this bandwidth (4800Mbps)?

    Thank you so much!

    • Hi Ray,

      1. No, you can’t change the LAN 1 into the primary WAN port. Like I said many times in the review, there’s no Multi-Gig LAN option on the router unit. Period.

      2. Yes, the Internet connection still depends on the (Wireless) backhaul between the node and the router. Keep that in mind.

      3. There’s no 3rd 5GHz setup but only using the 5GHz-2 (backhaul) band as a separate SSID. It would be best if you reread the review. Your PC can’t connect at 4800Mbps since there are no faster clients than 2×2 (2400Mbps), at least for now. More in this post.

      • Hi,

        I read your review in other post (https://dongknows.com/multi-gigabit-wi-fi-6-routers-to-bring-home-today/), you mentioned “Also, when using the XT8 as a single router, you can turn one of the three Gigabit LAN ports into a WAN and the WAN port into a Multi-Gig LAN.”. But based on your reply in No.1,you said I cant change LAN 1 into the primary WAN port as there’s no Multi-Gig LAN option on the router unit. I’m confused.

        Yes, I meant the 5Ghz-2, so there will be 3 SSID, 2.4G, 5G-1 and 5G-2, right? But do you know which bandwidth that both router and node used for connection? is it the 4800Mbps?

        Any news about 4×4 (4800Mbps) wifi card soon? I heard Asus going to launch it last year, but till now, I dont see anything yet.


        • Sorry for the confusion, Ray. That was a mistake. I was trying to say something about Dual-WAN and mistyped it. The 5GHz-2 is used as a backhaul, as mentioned in the review. I don’t think faster-than-2×2 clients will be available soon, if at all. But more bandwidth also means the broadcaster can handle more clients at the same time. More in this post.

          • Hi Dong, once again, thanks for your reply!

            Based on your review, I noted that the 5Ghz-2 was used as deliciated backhaul, this would means both router and node actually using it for connection, right?

            I noted also the 5Ghz-1 is not support 160MHz channel, and it generally capped at 1200Mbps. Is there any new firmware update to open the front-haul to support 4×4 160MHz? or any firmware update to improve the 1200Mbps to 2400Mbps?

            For wireless setting, can the 5GHz-2 be used at the same time as dedicated backhaul and connect to my PC (client)?

            Thank you for answering my questions.

      • Hi Dong.

        I’m very curious on what you mean by your review “ you’ll need to have a second node unit before you can see the value of this port”.

        Are you saying that with a 3rd unit of XT8, one will be able to make use of the 2.5gbe port? How does this work?

        I presently own 2 unit of the XT8 and I have recently bought an Asustor NAS, but I’m having slow file transfer speed of 20-25MB max. Have tried out various different settings by connecting to the main unit and node unit, but nothing is solving the problem.


        • That’s likely due to the server itself, Rudran. I’d recommend a Synology. As for what I say, it’s just math, if you don’t have a 2nd unit, there’s no way you can see the full 2.5Gbps locally. But that does NOT specifically apply to your case unless your NAS server has a Multi-Gig port.

          • Thanks Dong. My NAS server does have 2X 2.5gbe port. Yet the transfer speed over LAN is slow. 🙁

  28. Great review. When you are comparing the speeds of the various Mesh systems, does the distance you show include things like walls?

    This ASUS XT8 seems like a great system. Trying to decide between this, the Alien and Netgear Orbi 6. I was leaning towards this one, though wonder about the Wifi 5 speeds versus the Orbi 6 (AX6000)? And the Alien looks incredibly cool, but again for the fastest speed and reliability, which is your recommendation?

    House is an old house. About 5000 square feet (excluding garden). The “internet” connection from the ISP comes in at one end, and on the exact opposite end is my office upstairs and a Smart TV downstairs. There are brick walls inside and at the moment I’m looking for a wireless backhaul mesh system to somehow maximise/utilise the 900Mbps service.

    Ideally I’d love to future proof for Wifi 6, or 6E (or 7 at this rate), though I’m guessing only new smartphones can connect that way. I probably won’t be replacing my Mac any time soon (though you never know). And I guess it’s possible to connect via ethernet to the satellite unit of a Mesh system too am I right?

    Also, is there any way to know beforehand whether one should be buying a 2 unit pack, or 3 unit pack?

  29. Hi Dong, Thanks !
    The post is quiite impressive.
    Just would like to know, whether XT8 support upnp or not.
    Your response will be highly appreciated

    • Yes, Mukesh. Like almost all Asus routers, you can find the XT8’s UPnP toggle in the WAN section of its interface.

  30. Nice review. Just to clarify, when you were talking about the Wifi 5 speed the client can get owing to it being a 2×2, you wrote in the article “some 660Mbps and 450Mbps”. On the table/chart below that, it says 553 and 450Mps for the XT8 right?

    Could you just clarify whether it’s 553, or 663?

  31. Hi – great resource on the topic! I have a CT8 mesh system and am thinking of upgrading to an XT8. Can I mix the two in AP mode? I’m assuming if I connect the XT8 to the main router and then add in the CT8 units [2] as nodes – that will be okay? [We have a large house]. I’m also assuming that anyone within range of the XT8 will get Wifi 6 – but those close to the CT8s will only get Wifi 5?

  32. Dong, nice review. Are these definitely easy to use to provide a stable connection for the home?

    And secondly, do these provide faster speeds than the Orbi AX 6000 if we measure using wireless backhaul with both that and the ASUS? I got the impression from one of your charts that the Orbi was a faster speed?

    The ASUS sounded better, but I got confused by the speed chart shared. Would appreciate you clarifying, thanks

  33. Hey Dong. Great site. I bought this unit a few years back after seeing great reviews. It has worked great since then after following the advice here after firmware updates. My Node is connected to the main unit via Wi-Fi. We recently finished our basement and I had the basement hardwired for ethernet. I purchased three new TVs and attempted to connect them but none of them will connect to the Internet successfully via Ethernet. I connected my MacBook to each of those ethernet lines with no problem. All of the TVs will connect to the Internet via Wi-Fi. I also have a PlayStation that connected to Wi-Fi previously with no issue and still connects via Wi-Fi but will not connect via ethernet either. I’m at a lost. Just as a reference I have all of these ethernet lines plugged into a switch which then connects to the main router. For testing purposes, I plugged one of those ethernet lines directly into the router by passing the switch to rule our the switch as a problem, but I still cannot connect the TV to the Internet via ethernet.

    I’m looking for some advice on your experience with this unit if there is something special that I need to change in the settings To allow the ethernet to work. I don’t think so but I am at a loss here. Any help would be greatly appreciated. Thanks again

    • It looks like an issue with the TVs themselves, Kevin. You need to check with their manual or the manufacturer.

      • Hey Dong and Kevin,
        I had a similar problem with my two units. I would periodically lose connectivity on anything connected through Ethernet. Was unable to fix it working with ASUS so they replaced the 2 units, everything has worked fine since. It is unlikely your problem is with the unit but it could be.

  34. Hi Dong,

    I just read your post titled “Double NAT vs. Single NAT: How to Best Handle an (ISP-Provide) Gateway” last night and it was super informative. I currently have a Gateway from my ISP, do you think the Asus XT8 can be used as two APs for the Gateway to get the best coverage for my house?

    I was hoping to utilize the cables that run through the house to hardwire the XT8 units on the main floor and upstairs so that they will provide the best wifi speeds.

    What are you thoughts on using the XT8 as APs for my Gateway? Or do you have another suggestion that I could potentially look at.

    • Yes, Ken. The XT8 has the AP mode (as I noted in the review). And it would be best if you used the XT8 as the router of your home and the gateway in the bridge mode. Also, if you run cables, the XT8 is not a great choice (though it’ll work out fine.) By the way, all you asked has been addressed in this review and the double-NAT post. My suggestion is you read anything here in its entirety. 🙂

  35. My AC88U finally bit the dust and can no longer keep a 5Ghz connection. Looking at either the XT8 (2-pack) or the AX92U (2-pack) for the new mesh system. I only get about 400 up/down on my internet so just looking for a solid stable connection across my devices. Which would you go with? I want to ensure if we do get fiber that the router can maximize the speeds across the devices. One is the big difference between these two routers as they seem on paper to be very similar.

    -Thanks, love the site!

  36. all the asus routers including this one has only 16 parental control device list, which is very unfortunate since i have like 30 iot wifi switches which i don’t want to have them ping back home. is there a way around this? here is the feature i am talking about: https://demoui.asus.com/ParentalControl.asp
    Also Dong any chance you can suugest any other router which has atleast 30 device which can block internet but allow internal communication?

  37. Hi Dong,

    This site is great. Thank you for all this information. I recently rearranged my home where my primary PC is now on wifi (previously it was hardwired and I was getting very close to 1 Gbps (I have a gig connection and gig hardware (switch and Cat 5e cables)). I have an ASUS Blue Cave as my primary router and a ASUS AC1900P as the node which is hard wired and I have good coverage throughout my home. Because I have moved my primary desktop PC, I use a USB wifi adapter and I am getting a 250 Mbps connection. I would like a faster connection to the desktop and I am planning other peripherals near the desktop that I would like to be connected via ethernet. I am thinking of upgrading to WIFI 6 and considering the Zen WIFI XT8 2 pack. I have 3 scenarios and I’d like your thoughts on them, please.

    1) Zen WIFI XT8 (2 pack): One would be the primary router and the second would be next to my PC using wireless backhaul to maximize the internet connection. I would not use the other 2 WIFI 5 routers.

    2) Zen WIFI XT8 (2 pack): One would be the primary router and the second would be next to my PC using wireless backhaul to maximize the internet connection. I would use the other 2 WIFI 5 routers as nodes connected via ethernet back haul. (I have good coverage in my home currently but perhaps this will give me faster connections?)

    3) One Zen WIFI XT8 unit only as the primary router, the Blue Cave as a node (wireless backhaul), the AC1900P as a node (wired). (My home is only 3000 sq ft and should have good coverage with only one XT8 unit. Would the wireless backhaul to the Blue Cave utilize the full 5Ghz band?)

    4) I am open to other suggestions involving other ASUS AX routers.

    Thank you!

  38. I’m not that much of a internet reader to be honest but
    your blogs really nice, keep it up! I’ll go ahead and bookmark your site to come back later.
    All the best

  39. Hi Dong
    I have a problem with the stability of the wifi speed in my XT8.
    Both units are connected by cable (the icons in the application confirm it). When I stand at the Nod, the speed is 700/500, then I walk inside the house (e.g. approaching the main unit) and when I return back to the NOD unit, I have a speed of 120/50. The same is true for the main unit (router). For faster speeds to come back, I have to turn off and on the wifi on my phone.

    Do you have any idea what it results from?

    (I will add that the internet is stable at 950/500).

    Thanks in advance.

    • Separate the 2.4GHz from 5GHz, Marcin. Your device just got to switch to 2.4GHz as you move because this band’s signal is stronger. Or you can wait 5-10 mins each time you move before testing. And no, you didn’t have a problem with stability. Things are just not what you expected.

  40. The first review of xt8 was done in Feb 2020. It’s now Jul 2021. Is the XT8 still worth getting as it’s almost 2 years old model or should I just wait another half year or so in hope of a new model to replace the XT8? Is the XD6 a good option since it’s newer?

  41. Hi, Dong,

    Best reviews on the internet. Before reading through your work, I was just going to go with an Orbi setup. I have gigabit internet, and I got a great deal on some SRK60s ($75 each) and then SRK80s ($165 each!). But while I want a stable connection with minimal restarts, I don’t like the Orbi lag I keep hearing about and would like to do things like band assignments, scheduling, and incremental improvements in the future.

    So I found another great deal on several XT8s ($150 each). But in the back of my head, I kept hearing you say “wired backhaul”, so I took another look at my config again and realized I may be able to do just that (getting in the crawl space this afternoon with some fish tape; at least 1 or 2 sats can be wired, 1 is still in question).

    If I want fast and stable and am able to wire everything up, should I keep the XT8s or start looking for deals on RT-AX86Us or maybe a GT-AX11000 w some 92s? (Would there be an advantage to using the 2.5gb for the wired backhaul, by the way? I’ll probably put my synology and desktop on a multigig switch with link agg, so not sure what I’ll be doing with the 2.5gb).

    If I must do hybrid, are the XT8s the way to go?

    Am I being dumb (i.e., is my family going to yell at me often) for leaving 3 or 4 SRK80s and moving into the ASUS platform?

    Thanks so much for all the hard work; I’ll keep ad-block off and continue using your Amz links!

    • It would be best if you moved to Asus, Jeff. The XT8 will work with a wired backhaul. It’s just that it *might* have issues after a firmware update (this has happened). If you’re going hybrid and money is not an issue (it seems like that), I’d use the GT-AX11000 as the main and a couple of RT-AX92U as nodes — you can also go all of the latter. This way, things will be great no matter if you go wireless, wired, or mixed. If you want things to be stable, turn off 160MHz — more in this post. Oh, I can’t say anything about your family yelling at you. In fact, if you find out how to be safe from that, please let me know.

      • Thank you for this, Dong. Incredibly helpful.

        I ended up pulling the trigger on a GT-AX11000. I’m doing my typical sanity check with just one router (always the same location), a wired machine running iperf3 (if you’re not familiar, you might consider it over the file-sending methodology), and tests all over my home. I’m consistently getting 150-250 Mbits/s less than on a single GT-AX11000 than a single XT8. I know you get these questions a lot, and they’re hard to debug, but if you can think of anything off-hand that might explain the surprising difference, I’d love to hear it.

        I have all the game priority stuff off on the AX11000 running smart connect across 2.4, 5-1, and 5-2; otherwise it’s a recently-reset router-mode setup.

        • I’d stop using iperf, Jeff, seriously. I don’t use it for a reason. But it’s your call, just don’t count me in. 🙂

  42. Dong, thanks for the great article and review of the XT8’s! I picked up a set of these and wired them into my AX88U Router. Performance has been great to wireless clients. I have experienced a problem with my NEST thermostat falling off the network (and have noticed the ping going to 57K ms)! Rebooting the XT8 node clears it for an hour or so but it keeps happening. I swapped the other node with the one closest to the NEST and voila! no more problems. Do you think I have a bad node?

    • Not really, Robert. It might have been the Nest has been connected to the same node in the first place. It’s a bit tricky in your case to figure things out since you’re using tri-band nodes and a dual-band router. More in this post.

      • Dong,
        Thx for this review. I have a few questions. I day trade from my home office ( 3k sq ft and on the 2nd floor) I have AT&T internet 1000 fiber 1gb. Would I need two units or may I do just one unit? Amazon has 1 or 2 unit setups. Also, will this increase my internet speed? My rig is wifi 6 capable. Should I do a mesh system or wifi 6 router? Apologies to Robert for jumping on his thread, but I couldn’t find a way to ask questions.

  43. Hi Dong,

    Thanks for the great review.

    I’ve got a 2.2 Gigabit internet connection with the Cat 7 ethernet from my modem going into the 2.5G on the WAN port on the XT8, the problem is, my router is connected to the node using wired backhaul from the routers Gigabit port so my node wont be getting full speeds and the gigabit port becomes the bottleneck. Is there anyway to do link aggregation for wired backhaul between both units?

    Thanks for your help.

  44. Hi Dong,

    I took your earlier advise and split the bands on my xt8 router. I have the 2 pack set, with on primary and 1 AI mesh over the 5ghz wireless band.

    I move specific devices to 5ghz and the iot devices to the 2.4ghz. All seems to work well except on robot vacuum clear. It’s meant to connect to the 2.4ghz only, yet it’s not discoverable and just won’t connect, even after factory reset to the vacuum device.

    I know it’s me router because I Hotspotted my mobile and managed to connect the vacuum easily.

    I read on a forum that sometimes ports need to be open, so I added those specific ports, and still no luck.

    Any thoughts on what on my router can be blocking this device from being discovered?

    Any specific setting that may need to be enabled or disabled?

    It may be worth while noting that all wifi6 setting are off since I have minimal wifi6 compatible devices and iot devices work better with wifi6 off.


      • Don’t, just took the plunge on the ax88u and 2 xt8s. The xt are hardwired to the 88u. I’m having a problem with one of the xt8s. Whenever I walk to the part of the house that is closest to the xt8 I get full signal on my iPhone but no web pages load. If I turn Wifi on and off it loads fine.

  45. Hi Dong! Just got a pair of XT8 the other day after the Deco X60 3-piece system didn’t exactly live up to my expectations in terms of speed and coverage. Allthough the XT8 was faster on the node unit, the system delivered a weaker or no signal far away in the garden and had worse coverage in the house than the X60 did even though i put them in exactly the same place. I only split the bands and used the 5GHz-2 as a hidden wireless backhaul in the setup. I only really got wifi-5 units to test the router so far and I guess that 200mb/s on the Deco node is a decent speed for my sons gaming on our 500/500 fiber line (I refuse to use wired backhaul). Do you think I can get better wifi-signal on the XT8 by changing the settings some more or should I go back to the X60?

      • Thanks for the input. I should say that the third Deco unit only covers a small piece of the front side of the house. The other 2 units cover the back side of the house and the garden, as do the Asus. Do you rellay think I get a better signal in the garden by placing another TX8 in the front side of the house?

        • adding another unit in the front of the house will likely not affect the signal in your garden. its surprising as my xt8s are giving me the ability to connect on the main road!! i stay on the second floor in an apartment building inset about 10m from the street, and the router isn’t really on the edge of the network – although there are no major walls impeding the signal to the road.

          perhaps a solution would be to place one node much closer to the garden, and give the node in the front of the house a little more work to do? also i wonder what the wireless backhaul signal strength is like, how many walls/how much space is there between the main mesh router and the node in question? I use wired backhaul, so im not really sure about how signal strength is affected by placement, or how one can test it.

          Theres also an option to optimize the network once the nodes are all set up in their final locations. Maybe try that?

          Hope that helps,

      • Hi again Dong! Just compared my Sony Xperia XZ2 Compact to my wifes iPhone 8 and she has a much stronger and stable wifi connection to the XT8. So maybe the problem is with my phone. Gonna test the router some more before i decide. And perhaps get another unit 😉

  46. Hi Dong,

    I am upgrading my Wifi. I have an old AC5300 router.

    I just got a AX88 router (Came with topup for re-contracting my Internet)

    So I am wondering if I should get 2 units of XT88 to connect to the Main router AX88. Downside is the AX88 is only dual band, not sure if it is a good idea.

    The other method will be to buy a Powerline and use the XD4.

    Here is a picture of my proposed setup with floorplan. I am usually in bedroom 3 but it doesn’t have a cable connectivity.


    • Use the old AC5300 as a wired backhaul node of the AX88U (or in the AP mode), where you’d place the wired XT8, and you’re set, Nick. There’s no need to get a new set of XT8. More in this post.

  47. Hi Dong, I have a question about guest mode and wired/wireless backhaul. My setup is a ASUS GT -AX11000 with 2 ZenWiFi AX in wireless mesh mode. The main unit is on the top floor (3rd floor) with the 2 Zen units directly below on the 2nd and 1st floor almost directly below each other. I can do wired backhaul on the 2nd floor unit but not the 1st floor unit. The question is can I place the 2nd floor unit in wired backhaul and turn on its guest mode? What’s odd is the two zen units always connect directly to the main router but never to each other.

    • I’ve never been to your home, Carmine, so the floors you mentioned don’t mean much in terms of showing the spaces between the hardware. However, if you have a wired backhaul from the router to one of the XT8s, then there’s no need to worry about placement or to which device the other node connects. That makes no difference.

  48. I want to thank you for all the reviews that you do, and the help that you give your readers and fans. You do a great job, and are really appreciated out here in user land.

    I do have a question about the ZenWiFi. If I use wired backhaul and can now access the 5GHz-2 radio as a result, does it make sense to use just the 5GHz-2 radio, since it’s a 4X4? While I see an option for smart connect for 2.4GHz, 5GHz-1, and 5GHz-2, I don’t see an option for just 2.4GHz. and 5GHz-2. What I see when I use the tri-band smart connect is that most clients end up on the 5GHz-1 radio, with one or two on the 5GHz-2 radio. I’d like it to be the other way around, I think, since the 5GHz-2 radio has twice the horsepower that the 5GHz-1 radio has, as it were.

    Do you have any comments on this, whether I should make the 5GHz-2 radio my main client radio with wired backhaul or not? Or is there a speed advantage to having 2X2 clients on the 2X2 radio? Not clear to me, I’d really like to hear what you think about that.


    • Hey,

      I’m using two xt8 as nodes and one ax88 as main router. In this configuration it ist possible to deactivate each band separately. I’m only using the 2,4 and the 5ghz-2 at the moment. The 5ghz-1 uses the lower channels. I’m actually using no device which needs these lower channels and to give the neighbors some space on the 5ghz.

        • Are you sure that the wired backhaul option isn’t available if one xt8 is in router mode. It’s located at the main router AiMesh>Settings(at the top of the overview)>wired backhaul
          By default this setting is off.

          • I never said it was not available. Read the review again, Marcus, and other related posts.

        • Dong –

          I have an XT8, live next to an international airport, and can’t access 160mhz for backhaul. Would I be better off with a different mesh system?


          • Yes, D. Either that, or you need to turn the use of the DFS channels off completely via the web interface — configure the 5GHz-2 band to use only the 80MHz. It’s a bit of work to get that done but it’s doable. 2400Mbps for backhaul is plenty.

          • Dong – thanks so much. I locked it on 80 and am getting much higher speeds. Really appreciate it. -D

    • I don’t use smart connect but I do have wired backhaul between my two xt8 nodes. All my 5ghz clients use the 5-2 band (wifi 6 clients – macbook, dell, etc) and the 2.4 ghz bands (ring, nest, sonos, etc). I have the 5-1 band enabled but It’s normally unused. I do see in the professional tab for wireless that there is an ‘enable radio’ switch for each band. I haven’t tried to disable the normal 5-1 band though – it may or may not work.

  49. Hi,

    Would like your thoughts regarding how I can boost the standard settings on my Asus mesh system with 3 Asus zenwifi ax xt8. I have fiber 1000/1000 in and all connections are via wifi. I have a lot of IoT devices and other devices in total 40. Some are using 2,4 hz and most 5 hz. How can I boost my mesh? I have the latest firmware.

    • There’s no such thing as a “boost” for Wi-Fi, Zoran, that’s a terrible marketing term designed to fool people. Don’t use it. You can only “extend” a network. When doing it wirelessly, you generally will lose speed. More on that in this post.

  50. A short feedback from me.
    I’m running the Ax88u as main router. i got two xt8 for a low price and wanted to integrate them into my network as node. Adding them as node with a wired connection is pretty easy. The only challenge was to get the second 5G available for clients. By default the 5G-2 is used as Backhaul connection which is not necessary if they are connected by wire. After couple of hours testing an searching I got the 5G-2 finally released. The Ax88u is running with both 2,4 and the 5G. Both xt8 are running with 2,4 and the 5G plus 5G-2 merged together as a single 5G without smart connect enabled.

    • “By default the 5G-2 is used as Backhaul connection which is not necessary if they are connected by wire. After couple of hours testing an searching I got the 5G-2 finally released.”

      So how did you do this?

      • You have to go to AiMesh>system settings(which is located at the top of the page above the “add aimesh node” and “optimization” button)>Ethernet backhaul mode and turn the toggle on.
        Thereafter the 5ghz-2 is available for clients and each radio (2,4, 5ghz-1and 5ghz-2)can be enabled separately for each node

  51. Hey Dong,

    Thanks for the post.

    I have had the ZenWifi AX for 3 months now, but I tend to have Wifi stability issues.

    * The 2.4G is dedicated to connected home devices (light bulbs, door lock, thermostat, etc.). There is about 20 clients on the 2.4G network over the 2 nodes. But many times, turning the lights on/off some devices are delayed by >15seconds.

    * The 5GhZ network is used by phones, laptops and music streamers. When running a speed test with Wifi 5 MacBook Pro (6 feet from the router, direct line of sight), I noticed that the first 5-6 seconds of the speed test stall at 60-70Mbps, before gradually increasing to 300Mbps down / 600Up (sometimes with a big dip back to 70 along the way).

    Same test wired to the router I run at 600Mbps down, and 800Up, and I reach those speeds almost instantly and keep them.

    Any idea what could be happening? Any diagnostic tips and tools ? Optimisation guides ?

    Many thanks.

      • Dong,

        Your site is by far and away the defacto source of quality information. In formation. Thank you so much for sharing your knowledge. In my case I know have too much information and I’m hesitant on making a wrong decision. My home is old 1923 brick house with thick walls, A basement, 2 floors and an attic that all need top notch wifi. I was looking at the XT8 for my solution. I want to use a wired backhaul. Two questions. You mention that the XT8 is only good for a wireless backhaul but now with AiMesh 2.0 exposing the second 5G network to clients is not a good solution? Also I don’t believe a synced pair would suffice. Are there any issues in combining 2 sets of XT8 in one mesh network? Thank again!

        • If you use wired backhaul, it’s better to go with one of these AiMesh sets, Dino. The XT8 will work but new firmware updates *might* cause issues, that has happened before. But to answer your questions, you can also open the 2nd 5GHz band to clients, no matter what. And four XT8 units will work fine together.

  52. Hey Dong,

    I’ve read both of your XT8 & CT8 reviews, & I’m still unsure on which one to get. I am moving into a new home, & will be just getting Verizon Fios 500mbps internet service. The house is about 1700sqft: two floors, a basement, & backyard. What I’m mostly looking for is great speed & coverage to all the ends of the house, & want to get all, if not most, of the mbps I’m paying for from both the router & satellite. Also, the router & satellite will be connected wirelessly. I don’t have many devices that will take advantage of the WiFi 6. Can’t go wrong with either one, but would love your input! Thank you for your work as well.

  53. Hey Dong,

    Reading both of your reviews on the CT8 & XT8, I’m still kind of unsure which one to get. I am currently moving to a new home & will be just getting the 500mbps Verizon Fios internet service. The new home is roughly 1700 sqft; two floors, a basement, & backyard. What I’m mostly looking for is great coverage & speed on all ends of the home, & getting most of the mbps I’m paying for from both the router & satellite. Also, both the router & satellite will be connecting wirelessly. I don’t have many devices that will take advantage of the WiFi 6. Pretty sure I can’t go wrong with either one, but would love your input! Thank you for your work.

    • You already got the answer, Chris. Either will work out well considering your place is relatively small. But with the yard, you’re better off with a 2-pack. I’d go with the XT8, which has a better backhaul range, just to be sure, but if money is tight, go with the CT8. You probably won’t see the difference.

  54. Hello Dong,

    Thank you for all your reviews. I have been your follower since many years and I appreciate your work a lot.

    My new house is about 8000sft on a single level. I have previously used Asus Rt86u along with Merlin and it is the best router I have used.

    My new house has ethernet cables running all over so I can run a wired backhaul.

    My question is: will 2/3 more 86u routers with merlin be a better choice than the XT8 for mesh benefits.

    My primary need is seamless transfer of wifi when I move around the house.

  55. Hi Dong,

    Thank you for you insight. I’ve purchased the xt8 a few months ago however I’m experiencing a few issues which I believe could be configuration related.
    1. My wifi cameras often lose connectivity for a few seconds? Is this related to the aimesh finding the best channel and closest node?
    2. My Google home devices don’t work with snooping turned enabled. They lose connectivity
    3. Wifi bulbs sometimes disconnect and need to be reset to reconnect

    I mainly have wifi 5 devices and I’m using smart connect (2.4 + 5ghz). If I use individual network Google devices act up.

    Any guidance on the optimal configuration?

    • The connectivity issues you’re experiencing are frequently related to DHCP.
      Besides upgrading the devices to the latest firmware, define static IP addresses for them in the router, and configure the devices to that IP address, rather than fetch it from the DHCP server.

  56. Hi Dong,
    I posted before that I was having problems with my second XT8 node connecting to the router and you suggested that I wait for the next firmware and reset the system. Since then I have tried multiple firmware versions including the latest version, reset the system multiple times by holding a paper clip in the reset buttons, swapped the second node with the router, all to no avail. And it doesn’t matter how far the the node is from the router either, I’ve tried from inside the same room and multiple rooms. All I get is it goes from a Great connection, to eventually a Weak connection to Not Connected at all and back again. I was just wondering if there is anything I can try that I haven’t tried yet. I wonder if the system is actually being fully reset as sometimes the second nodes blue light is quickly blinking when it says it is connected. I’ve tried calling Asus but their wait time is long which is why I am asking here. Again, I truly enjoy your site. Thanks for any possible ideas.

    • Try the 30-30-30 reset on all units, Mark. That’s when you press the reset button for 30 seconds, then unplug the router from its power source for 30 seconds, then plug it in with the reset button still depressed for another 30 seconds. In all, you press and hold the reset button for 90 seconds. Note that might put the routers in the recovery mode. In this case, you just need to load the firmware on them via the web interface, so make sure you download the firmware on your computer first.

  57. Hi Don, Firstly thanks so much for your website it is a recent find and has been an invaluable source of knowledge.

    I am wondering if it is better to get a ready Mesh system like the Asus Zenwifi AX XT8 Mesh-system or alternatively I have been really close to getting an Asus RT-AX86U that you have recommended and adding another one to create a mesh in my house. Which would you recommend?

    Really appreciate any answer!

  58. Hi Dong, thanks for the great review!
    I want to upgrade my Airport Time Capsule to WIFI 6 system, currently airport covers my house well, and I get usable 5G signal in all locations except for two far corners where the speed drops down to 20Mbps.
    I have 1Gbps fiber connection with ISP router in one corner of the house, and I essentially need an AP in my living room (which is the centre of the house). I know there are better standalone routers, but I need something that also look nice in my living room. So my questions:
    1) Do you think a single XT8 or Linksys MX4200 can cover my house? In your test which one has an edge in coverage?
    2) Does XT8 support bridge mode and I can later add more mesh nodes (I’m pretty sure Linksys does but not sure about Asus)?
    3) Do you recall the length of power cord of XT8 and MX4200? I ask because I need to place the router 2,2 meters away from the power supplier.
    Thank you in advance!

      • Also no known problem with update. Does anyone know if ASUS provides a more detailed README or other file providing more detailed information on what each update does other than simply listing the CVE’s fixed? What is on their website is pretty basic, and a somewhat more complete update history file would be very useful. Any pointers would be helpful. Thanks

    • Not very stable. Reboots at random intervals. And this is after I have my router set to reboot every night @ 3:00am.

    • Couple of weeks of continuous uptime on 42095 at this point. This firmware version has been stable, no problems. There is one repeating message in the system log “not mesh client, can’t update it’s ip” as I recall, but apparently doesn’t have any effect. Mesh is working fine. It would be nice if Asus would fix that, and no spontaneous reboots, disconnects, etc.

      Oh yeah, I don’t use scheduled reboots, haven’t needed to.

    • I did upgrade and found that it was stable – except that Sonos equipment would not connect in a stable manner. Apparently with Asus you need to do a hard reset and manually reconfigure the system for it to work with Sonos. Once I did that all my Sonos equipment started working perfectly again.

      I suspect the source of the issue is some sort of carryover misconfiguration/corruption after upgrades that makes this necessary. It’s unfortunate that Asus’s firmware has such issues.

  59. Thanks for your review. I just ordered a pair of XT8s and I’m planning on using them in AP mode, connecting my existing ‘gateway’ (Cisco ASA) to a LAN port of the nearest unit. Could you confirm that I won’t be able to use the guest network feature since these units won’t be routing traffic?
    I hope that the traffic inspection/security features will still work, or are they bound to the WAN port, which won’t be used?
    Finally, I couldn’t find any reference to VLANs in the user manual except for ‘VID’ on the IPTV setup page. Is there any way to map a SSID to a particular VLAN? That’s what I’m doing today with the AP the XT8s will replace.
    Thanks again for your in-depth review.

    • None of what you mentioned will work, Dan. In the AP mode, the mesh will do nothing but broadcasting Wi-Fi signals. However, if you use each XT8 unit as an individual AP, then you’ll be able to control each’s Wi-Fi settings as well as using its Guest network/USB features. No other features are available.

      • Thanks for your reply. Looks like it might not be the best system for my use case. Do you have a recommendation for an AP-only mesh system?

          • Thanks a lot, the TP-Link Omada seems to be what I was looking for.
            My setup would use one root AP and one mesh AP. I can’t tell if a 5Ghz band is dedicated to the wireless uplink, do you know if that’s the case?
            Also, a controller is required to setup the mesh network according to the tplink website. I’ll be able to run the software version however, so it shouldn’t be a problem.
            Thanks again for pointing me in the right direction.

          • Not sure I understand your comment. The mesh AP will be powered via PoE, but, by definition, will only connect to the network wirelessly (via the root AP). So traffic from stations associated with the mesh AP has to be backhauled wirelessly to the root AP. I am not sure how it is implemented on the EAP245v3.

          • You need a router or a switch, Dan. The APs connect to each other via the wired backhaul. You can make it work wirelessly but the performance is far worse. Try it.

          • Got it. If I had a wired connection available at the second location where I want Wi-Fi coverage, I would just buy another AP. But I don’t, that’s why I’m looking into ‘wireless mesh’ solution. The XT8s looked good because of the features and dedicated backhaul band. But most, if not all of the features, won’t be available to me since I have no use for the router part. I know about dual-NAT and I’m not interested 🙂
            If only TP-Link would add a dedicated radio, it would be perfect.
            At least I know where I stand now. I might still give a try to the TP-Link option, my second location only has a few devices so coverage is more important than bandwidth.
            Thanks again for your feedback.

          • Thanks again. I’m spending way too much time on this 🙂
            Now I’m thinking of upgrading my existing AP to the EAP245 and using the EX8000 for the second location. The EAP245 is 3×3, not 4×4, but I think that I should still get decent backhaul speed.
            Of course, there’s the nanoHD which is 4×4, but twice the price…

      • Dong, IIUC his suggested setup is:
        WWW Cisco ASA (wired only) XT8 ))) XT8
        Isn’t that exactly what “Access Point(AP) mode / AiMesh Router in AP mode” is for?
        The dedicated backhaul should still work for him, as will the guest network etc.

        • The Guest network will work if you each router individually in the AP mode, not as a mesh in the AP mode, Dror.

  60. Hello, Mr. Ngo,

    I wanted to state my appreciation for your recommendations and also sharing your expertise on routers over the years. I just recently upgraded to the XT8, but I got caught up in thinking that I needed a mesh system. Actually, my house is only about 1800 Sq. Ft. total, so just one standalone router is more than enough. The single XT8 is against the wall in my basement, but I’m still getting the full download speed of my ISP plan (500 Mbps) from the opposite wall upstairs. Thanks again, and stay safe!

  61. Hi Dong, I have been running a pair of these AX routers for 4 months and apart from initial issue that I managed to resolve with help on here they have been superb. I have them scheduled to reboot twice a week in the middle of the night and now have backup of my configuration which I would recommend before doing any tinkering. I would know like to try and extend coverage to an outbuilding on property that’s 100ft from closest box. I have a garage I could place a box in to reduce distance to 50 meters. My current speed around house is over 100 and would be happy to get 20 in my outbuilding. Any advice on adding extra nodes to network that would get me this outcome at the most affordable price would be very much appreciated, thanks Andy

  62. Hello hope everything is good

    I’m about to get the asus zenwifi xt8 ax6600 but I have a question

    Main router/ modem —— asus Tx8 —- switch—— each Tx8 will be hard wired via Ethernet to the wall and and directly connect to the switch, will it work? And dose the performance going to be better?

    • That’s fine, Aziz. But in this case, I’d recommend not getting the XT8, but the XD4 (or a few dual-band routers) instead.

  63. Will just one unit of Asus ZenWiFi AX XT8 as a router cover a house of 110m2, if placed in one corner of the house? I know in theory it will, but
    the distance form the router (on the ground floor) to one of computers on the 1st floor will be around 15m, with walls 2 between. Maybe two units of mini version will work better?

    • That depends on the walls around the house, Artur, but it likely will work. Better yet, try to run a cable and move the router closer to the middle.

      • Thanks, do you know what signal strength will single router deliver at 15-20 meters away?
        In general which of these options will deliver better signal at that range: single ZenWiFi AX XT8 or two units of AX mini?

        • Impossible to tell, Artur. That depends on your place. If you have wired your home, then consider the XD4. If not, the XT8 is the way to go (that’s if a single router won’t cut it.)

  64. Hi Dong,

    I am struggling to decide between the Orbi 75x and Asus XT8.

    I am waiting on gig fiber to be installed. My concern with the X8 is stability and with the 750 the lack of features. In my set up will be connecting the mesh network over wifi as it is extremely unlikely to be able to run a cable. The last issue is that i want my work computer to be on the guest network, this looks to not work on the Orbi and on the Asus looks like guest wifi over the notes is relatively new…


  65. Hi Dong,

    Your website seems to be more comprehensive (and genuine) than a lot of big tech reviewer sites… It’s also impressive how you find time to answer hundreds of comments!

    My house is a 3 floor rectangle-shaped townhouse, with just a little less than 2000sq ft. I’ve got a 1Gbps fibre cable coming to my ground floor home office (corner of the building) and then the ISP router giving WiFi coverage, which really struggles with top floor, and has almost no features for security or parental control. It’s a rental property, so I can’t put any cabling in.

    After visiting multiple mainstream tech review sites, I found a great deal on a single brand new XT8 for £180 when it retails for £220 and bought it, but then discovered your website…

    After reading your guides and reviews, key takeaway is that a Tri-Band solution is a must in my case, as I cannot use the wired backhaul, HOWEVER it appears that a single router may be enough for the size of my house, and of course a similarly priced RT-AX92U (there’s actually a set of these for sale at £150 each at the moment) or RT-AX82U seem to have WAYYY more features.

    Have I made a mistake with the XT8, and should I swap it for 82/92? Looking into the future, perhaps sticking with XT8 and adding another unit for a mesh system would be the optimal, but I can’t get over the fact the RT series come with so many more features.

  66. Great reviews! I’m hooked and have already bookmarked your site. Thank you! My head is spinning from everything I’ve read. Maybe you can help. I have a 4300 sq. ft. house and I’m considering this XT8 mesh router unless you can recommend something else. Alternatively, I’m considering a combo mesh router and modem in one since I also need a modem, though I sense they aren’t very good. CBK752 is really the only one I’ve seen. I have 100mb internet – may increase to 200mb. I connect through cable. Any personal favorite on a good router and modem or combo unit to buy? Thank you! 🙂

    • I think the CBK752 will do, Victoria. It can handle multi-gig Internet so it’ll last you a very long time. And on the Wi-Fi side, it’s basically the RBK752.

      But generally, it’s a better idea to get a separate modem. That way you’re free to use any router/mesh you want. In that case, get one of these modems, then the XT8 if you want a fully wireless mesh system. If you have wired your home, use the XD4 instead. More on how to pick a mesh in general in this post.

  67. Great site Dong, first time poster here. I have had the 2 pack XT8 system for around 3 weeks now and it’s been rock solid, that is until today when I updated the firmware to version today and it’s been nothing but problems since then. Before updating, the second node’s connection always said Great. Now it goes between Weak and Disconnected. I reset the system to factory settings and the router reset but the node didn’t, so I did a hard reset and then ran the setup again. For a couple of hours it said the connection was Great but it’s gone back to going between Weak and Disconnected. I’d appreciate any advice you or anyone can give me to rectify this issue.


    • This happens a lot of this set, Mark. I’d recommend reverting to the previous firmware (you can do that manually, just download the firmware and flash them individually, on the node first, then on the router). Then wait for the next release before updating. 🙂

      • I bought zenwifi xt8 2-pack in december 2020 and was working great until I upgraded the firmware to version I had the same exact problem as stated here. The wireless backhaul quit working and my node would not connect to the router after this update. It kept going in and out and disconnecting. After much testing and calling ASUS support I ended up going back to the previous firmware version on the router and the node and now all is back to normal, working fine like when I bought it. I hope ASUS fixes whatever this problem is in the next firmware update for Zenwifi xt8. They should post something on the website not to update or remove the firmware update.

        • Yeah, that happens a lot, Jeff. I’d recommend not upgrading right away but wait for the subsequent release of any new firmware version. Thanks for sharing.

    • Thanks for posting Mark. I was going to update my set today however I think I’ll hold off for a while. My system has been fairly solid – I’ve only had to reboot them 3-4 times in 8 months.

      • Good call, Bruce! Either that or you might need to reset the router and set the mesh up from scratch with the new firmware. (You can backup and restore the settings.)

    • Has anyone else had similar issues with I am slightly concerned about upgrading to this version if it is unstable. Admittedly I am only using my 4 XT8 nodes as Access Points and have a 2.5G wired back haul.

      @Dong when I combine the 5-2 and 5-1 into a single SSID, do you believe I will see any performance improvement? Currently I get around 870mbps on Wi-Fi 6 on the 5-2 band but 917mbps via wired connection.

      • You can’t combine the two, Jez, you just put them in one Wi-Fi name. It’s a matter of convenience and has nothing to do with performance. You should wait till the next firmware before upgrading.

        • Ah ok, my back haul 5-2 ssid consistently out performs my 2.4ghz/5-1 ssid, so if I am just giving them the same name, i am guessing it would be just chance as to which one I am on? I might as well leave it separate so I know I am on 5-2?

          Sorry I don’t know too much about this!

          • If you want to make sure which band a device connects to, Jez, it’s best to separate them.

  68. I have had the 2 XT8 units for a few days. I have the latest firmware running.

    I have made the 5-2Ghz band visible to clients which is also wired backhaul between the two routers. I have connected my iPhone 12 to the 5Ghz-2 band however I never get about 610mbps download speed. I have a 1gbps download speed and on a wired connection to my PC I get full speed but on wireless my wifi6 client gets no more than 610mbps close by or far away from the router.

    Is there a reason why this might be the case as I’m expecting 800mbps download speeds to my wifi6 iPhone 12

  69. A quick question. I have a set of 2 zenwifi ax routers, one at each end of my house, that provide good wireless coverage for my whole house. I also have a second floor that’s above one of the two XT8’s where I have some wired clients. I’m thinking that if I get a third XT8 to provide for the wired clients upstairs that would be too much wireless, there’s already good wireless there from the downstairs XT8, and clients may get confused, and it may cause problems with the mesh. So I’m considering getting something like an RT-AX3000 and configure it as a media bridge upstairs to provide the wired ports I need.

    What do you think of this idea? Would you recommend getting another XT8 and risk having too many wireless nodes, or would you get the RT-AX3000 and use it as a media bridge with the good wifi I already have upstairs?


      • Thanks, helps to get a second opinion *smile*. Just got the AiMesh 2.0 firmware, seems to be working just fine for me as well. Lots of “new” features.

          • Just to followup here, got the Asus RT-AX3000 and it works well in media bridge mode. I’m seeing a speed test of about 600Mbps on my NVIDIA Shield upstairs without the MoCA. Using the MoCA, it’s about 800Mbps. The wifi-6 connection between the ZenWifi and AX 3000 appears to work well. Anyways, very happy with 600Mbps for streaming TV *smile*.

            Nice when a plan comes together!

  70. Hi Dong,

    After months of beta, ASUS released stable firmware for the XT8 that upgrades to AiMesh 2.0. Finally, Version has many updates including the long promised guest network that broadcasts from both the router and the nodes.

      • Now that wired backhaul combined with full bandwidth wireless on the second 5Ghz radio seems fully supported, there is one configuration option which I assume is fully supported but I’ve never actually seen mentioned: If one needs a 3 node configuration in order to get the coverage required, can you easily configure a 3 node wired backhaul configuration using 2 of XT8 LAN ports (on the node used as the router) as wired backhaul connections to the other 2 XT8 nodes? Also, in that configuration can you use the WAN ports on the 2 non-router nodes as LAN ports? Finally in a 3 node configuration, what is the argument for keeping all 3 nodes as XT8s or is there another ASUS router that one could use as the router node that might be less expensive but will still deliver the same functionality and performance? Is there an argument for homogeneity of boxes in an AImesh or is the ASUS mesh product really that seamless across disparate products?

          • Let me try a simpler version of the question. If you want to install a 3 node version of at XT8 mesh, can you configure this as all wired backhaul with the node being used as the primary router having wired backhaul connections (via 2 of its 3 LAN ports) to the other two nodes acting as extensions.

          • Yes, how else would you connect nodes through wired backhaul? That’s how wired connections to other nodes are normally connected.

          • You can connect however that is you want AND possible, Randal. The only important part is on the node, you must use its WAN port to connect to the existing network, be it a switch, the router unit, or another node. Take a deep breath, you’ve been over-analyzing stuff. And read this post on AiMesh.

          • That’s what I assumed in terms of an all wired configuration but wanted to make sure. The other option would be to daisy chain the wired nodes (primary router to node A, node A to node B) which may also be supported (?) but in my case isn’t preferred. But depending on where you needed LAN ports for uses other than backhaul I can see where the daisy chained configuration might be useful. For example if you needed more than 2 satellite nodes (and needed to reserve one of the LAN ports on the router node for a switch) you might need to do a combination of configurations to get all nodes attached via ethernet.

            The other part of my original question was “In a 3 or more node configuration, is there an argument for keeping all nodes as XT8s or is there another ASUS router that one could use as the router node that might be less expensive but will still deliver the same functionality and performance? Is there an argument for homogeneity of boxes in an Aimesh or is the ASUS mesh product really that seamless across disparate products?”

          • In theory it shouldn’t matter, but I’ve found more reliability (lately) running 4 XT8 rather than a AX11000 as my main router and 3 XT8 Nodes.

          • This is why you should use tri-band when you CANNOT use wired backhaul. With wired backhaul, use dual-band hardware. The reason is vendors make tri-band mesh systems with wireless backhaul in mind. So firmware updates for tri-band mesh are released based on THAT (the wireless use case) and might mess things up for those using wired backhaul. More here.

      • Hi Dong..

        Today after i update the zenwifi xt8 to new version, my second xt8 as ethernet node failure connection from my network switch..

        I have to unplug the node RJ45 from network switch and direct plug in to main xt8 router lan port only can work..

        Do you know what issue about that ?

        Appreciate for your reply..

        • That shouldn’t happen, Susukim. Try removing the node from the mesh then seting it up again with the switch in between. XT8 router (LAN port) -> switch -> (WAN port) XT8 node.

  71. Hi,

    Firmware was released yesterday 2/1/21, which now allows for a tri-band setup when using ethernet backhaul; this makes the second 5GHz band with 160MHz available as part of the mesh network.

    • It has always been available, Travis, just requires a bit of configuration. Thanks for the tip, though. 🙂

      • I guess what I’m saying is that ASUS followed up on their firmware update promise to you, which allows the second 5GHz band to be combined with the 2GHz & the first 5GHz bands, all on front haul, and all using the same SSID

  72. Hello Dong
    I have recently installed the XT8 pair, and find I still have a dead zone on the 2nd floor of our house (XT8 nodes are on main floor and basement). I read in your review of the Nighthawk EX7500 extender, you tested it with an Asus router. Did this operate as a mesh? Would this extender operate with the XT8 as a mesh? Just looking for a less expensive way to add a 2nd satellite instead of purchasing a single XT8 (which I cant find anyway).

  73. Hey Dong,

    Have had these for about a week now, and am very happy with them. Initially just used the app to do set up, let everything default to what the app wanted, and the mesh came right up. Over the next couple of days, made the changes that I wanted, like selecting channels instead of leaving as “auto” (when I saw that it had selected a DFS channel), turning off UPnP, changing the DHCP address pool, etc. Still working great, no down time, just fast wireless without a hard-wired connection, which was exactly what I was looking for. We do have MoCA that works fine, but consider it impermanent, our coax is old and won’t last forever. And I don’t see that I’d get enough better performance to make it a permanent part of the mesh. I do use the MoCA for other things, like reliable TV streaming, and am very happy that the ZenWifi AX has made us independent of it, that was my objective.

    I do have a question *smile*. If I want to add a second “node” (third router), and I add one that has only two radios, I assume that the ZenWifi AX routers will still use their dedicated backhaul radio between themselves. What I’m assuming is that I’ll see is that the added 2 radio router will have slower wireless, but the wireless at the 2 ZenWifi AX routers will still be about as fast as it was.

    Is that correct? Not sure if a less expensive router would degrade the whole mesh and I should pony up for a third XT8? Or if instead just the added node will be slower?


  74. Hi Dong, I currently have two Zenwifi XT8’s and am planning on getting one RT-AX92U. Would it be better to hook up the RTAX92U to the modem and use the other two XT8’s as nodes or does it not matter which one i connect directly to the modem.

    Thank you.

  75. On the XT8 if one “only” has a single gigabit/second to your ISP, rather than wasting the only 2.5 gbs on the main router, I assume there is no way to configure use one of the 1 gps ports for the ISP connection and save the 2.5 gbs port for a wired backhaul to the second router being used as an access point? While not knowing the details of the internal hardware architecture, one could imagine that possibly a firmware update could enable this? Do you know if this has been suggested to ASUS and their response? This would be really useful in cases where a significant portion of your traffic is local and only a portion is bound to the public Internet.

    • I haven’t tried this, Randall. While you can use the LAN1 as a WAN port in a Dual-WAN setup, I’m not sure if it’s possible to make the 2Gbps work as a regular LAN on the router. I’ll check with Asus and we’ll see how this pans out via future firmware.

      • Thanks for checking into this. This would be a really useful configuration option, as I suspect it will be a while before any ISPs start offering speeds above 1 gbps at least at any affordable price, so the 2.5 gbps second port is sort of wasted at the moment on both the XT8 used as the primary router, and also on the access point XT8. But being able to use them for a wired interconnect between the XT8s would be really useful if you have a lot of traffic both going in and out the WAN port but also to local devices such as a NAS. In fact since some higher end NASes allow for link bonding via LACP of 1 gbps ports, since the XT8 also allows for LAN port bonding/LACP you could then attach a local NAS to secondary XT8 for an effective 2 gbps local bandwidth and then still have two spare gbps LAN ports on the primary XT8 for things like a local gbps ethernet switch. This would enable an incredibly powerful local home LAN if all of this worked correctly.

        • While what you’re thinking makes sense on paper, Randall, it likely makes no difference in real life. That’s because chances are your end devices are all Gigabit (at best). The router needs to have more than one Multi-Gig port for what you think of to work out. For now, a single Multi-Gig connection to the server (either via the 2.5Gbps or Link Aggregation) still helps in the sense that the server can serve multiple clients better. But keep in mind that most servers cap at 6Gbps (on paper), which is the internal drives’ speed, and therefore likely MUCH lower in real-life, unless you use SSDs… Soon enough, we’ll have all 10Gbps routers and switches. For now, enjoy what you have however you like. 🙂

  76. Dong – thank you so much for your informative site and helping (more than you know) those that are learning all about networking. For best coverage of a large area, 7,000 sq. feet ranch – with thick walls – and the need for all wireless backhaul since that’s the only possibility, would you recommend 3x AX92Us or 3x AX AT8s? Connections are fairly standard in today’s world for a family with children – connected TV’s Speakers, Zooms, Rings, Nests, etc. We’re not gamers either. Thank you so much again for your advice and all the details you provide on your site as I’ve learned a great deal since I started reading.

  77. Hey Dong,
    I know it’s way to early but do you have any initial thoughts on the ASUS Zenwifi XD6 just announced vs the XT8? Just wondering if I need to wait in buying an router.


  78. Hey Dong!

    Thanks so much for the awesome review on the XT8.

    Just wanted to check regarding the 5ghz-2 band. Lets say I’m using a single node as the router and I made the 5ghz-2 available for clients, is the high speed only available for Wifi 6 compatible devices? And would the cap speed for Wifi 5 devices be similar to the 5ghz-1?

    Thanks in advance!

  79. I found an interesting post on the unavailability of the 160MHz channel width for the backhaul in the UK due to channel 124 (right in the middle) being used by weather radar.

    I suppose the 160MHz channels require the availability of a lot of the DFS channels. Are there many problems in the US?

  80. Hello Dong,

    In your review you wrote:

    “Update: Asus told me on February 11, 2020, that it would might release a new firmware update that opens up the front-haul to support 4×4 160MHz specs, effectively doubling the XT8’s Wi-Fi speed for clients. This doesn’t seem like a sure thing, however.”

    My question to you is, can a simple firmware update change the number of streams?

      • Thanks for all of the updates and advanced insight as to possible changes/upgrades to the XT8. Since you’re “in the know” to a greater degree than most of us, have you gotten any insights as to when/if Asus will be adding WiFi6E to the CT8/XT8 product line? Seems like if we’ve waited this long to upgrade to WiFi6/ax from our WiFi5/ac class routers, might be worth the additional wait for 6E. Thanks

  81. Great review and used it to get my zenwifi xt8 x2 to replace my ageing rt-68u. Only issue i have had is complete lockout of any hardwired connectivity. Internet and wireless continues to work but anything connected to ethernet will not show up and need to reboot device..it messes up my whole network and takes a little time to get everything back to normal. Using current firmware as off Dec 2020 and it setup up as default using th ewireless backaul to second mesh device !! very weird and not easy to bottom out. Not sure if a firmware issue.

    Thank you

    • I don’t see a question there, Gary. But it’s indeed weird. I’d recommend you reset the mesh and set it up from scratch.

    • Hi Gary,
      Had the same problem, went back and forth with ASUS support, finally they had me RMA both devices. It was a hardware issue so they replaced both devices. It will take a little work filling out their forms and sending setup files but stick with it, it’s worth your time.

    • thank you both, will do reset but already reset from fresh…wil do it again as it would be less tedious than an rma but I will persist if it happens again as it is so frustrating.


  82. Hi Dong,
    Thanks for a great review. I have been comparing the XT8 with the NETGEAR Orbi RBK852 (which is more expensive).

    The XT8 looks much better value, but I am not sure if the XT8 (W-2-PK) can be extended by adding another two satelittes nodes XT8 (W-2-PK) and still have a single mesh SSID for the whole home i.e allow a client device to roam the home and seamlessly switch to the XT8 node with the best signal. Would that work? I looked at the ASUS site and XT8 config beyond two nodes is not covered.

    I notes that Lars in Norway did this, but I was not sure if it would retain a single mesh SSID.

    The NETGEAR Orbi RBK852 can be extended with additional mesh nodes (RBK853 and RBK854) to extend the range of the mesh SSID for larger homes.

  83. With the latest beta firmware, there’s a “Force Ethernet Backhaul” toggle under the “AiMesh” section on the web interface (not the App). When I turn it on, Dual-Band Smart Connect turns into Tri-Band Smart Connect.

    Is it better to have Tri-Band Smart Connect On or Off?

    • Hi Azim,

      where do you see the Force Ethernet Backhaul toggle (Ethernet backhaul mode)? It seems to be missing in my web interface.
      Under AiMesh I see only topology as category – no system settings or similar.


      • Here’s how, Kay: AiMesh (section) -> Click on the node in question -> click on Network. You’ll see Link Type there which shows the current backhaul. Make sure you use the latest firmware.

      • Kay,

        As long as you’re on the latest beta. Go on the Web Interface:

        AiMesh -> System Settings

        In there, there is a toggle labeled “Ethernet Backhaul Mode”. Once that is enabled, TriBand Smart Connect became an option for me.

        • Thank you Dong and Azim, appreciate the help!

          I wasn’t aware it was only available in the current beta firmware – the Asus support article is a bit misleading as it says that the feature should be available in firmware version later than 386.xxxx.

          TriBand Smart Connect works perfectly for me now with the beta firmware!

  84. I just received mine today. So far so good and I’m impressed. I’m replacing an Orbi RBR50 2 node mesh system.

    One thing that I noticed it actually doesn’t support that the Orbi does is vlans. I wish Asus would add vlan support.

    I’m using the wireless backhaul right now to the second node upstairs in an old house with thick walls. I plan on running a cable between the two in the near future. I’m not sure if I would bother using the 5Ghz -2 with a dedicated SSID but maybe I’ll give it a shot some day.

    I don’t have any WiFi 6 devices yet, but I did notice my WiFi 5 speeds increase slightly especially on the upstairs second node.

    All in all, I’m impressed so far for the price. I almost went and purchased the $700+ Orbi system and I’m not sure it would have been worth it honestly. I could almost purchase two of these systems for that price.

    I’m not sure it would have made sense to go with any other WiFi 6 mesh system, this one seems to check most of the boxes.

    • Nice going, Colin! And, no, there’s no router or mesh that has everything, which is a good thing in a way. 🙂

  85. So far I’ve found the AX 6600 XT-8 to be a completely unreliable router. The first box I purchased had a DOA unit. OK, that happens. The replacement keeps going offline, sometimes for days at a time. There seems to be no way to bring it back up and ASUS support has been less than forthcoming about why this happens. This is not an inexpensive purchase. I expect more from a vendor, but perhaps I should not be so surprised. I’ve seen a lot of posts on the ASUS site about similar issues — just no fixes. ASUS also locked many of those posts so you can’t see the answers – just the questions. So perhaps that DOA unit wasn’t so unusual after all, eh?

    • Thanks for sharing your XP, Capros. The set I reviewed has been working well. Bit it seems there have been inconsistency in the quality of this hardware. 🙁

      • Too true. As a former reviewer of tech equipment, I well remember getting very thoroughly pre-tested products from vendors. It normally worked pretty well, but the retail products — well, not so much. I won’t say that’s what ASUS is doing — it’s just very disappointing that a former wonderful company now is putting out questionable products.

        Do *you* know how to get the router back up once the infernal red LED lights up? Rebooting doesn’t work, nor does anything I’ve found when I log into the web interface. Web app is useless.

          • Did that about four times. No joy. That’s what’s so frustrating. Two days ago it came back up after been down for over a week — last night it went down and this morning it was back up. Too strange.

            Keep up the good work. I enjoy your reviews.

    • I guess I’m one of the lucky one – mine has been working flawlessly for months now. Main unit downstairs hardwired to second unit upstairs – I’m mostly using the backhaul band (5-2Ghz I think it is) for my clients. My ISP’s cable modem is unfortunately much less reliable.

    • Mine XT8 pair is much more stable lately. Up&running for 3 weeks without interruption. There were frequent restarts in the past. In my case, restarts were related to the attached USB disk used for Time Machine. I wonder if anyone else had such an experience.
      I agree Asus support is not much of a help. They do not go deep and after a few interactions, they suggested returning the units.

      • Yes, Klemen, the USB drive for sure can affect the router’s overall performance (and stability). I haven’t done and exhaustive testing on this and generally only use one for a couple of hours when I review a router.

    • I think you are correct there are some hardware issues. I purchased mine back in April of this year and they worked fairly well, even better with the September firmware upgrade. Recently however I started to have a problem with all the Lan ports shutting down unexpectedly. WIFI continued to work but often at a much reduced speed, also it was never clear what brought them back on line, a router reboot, network reboot, or just waiting. I worked with Asus tech support who when unable to fix had me RMA them. It took about 2 week and then sent me two new units. Never told me what the problem was so I assumed it was hardware. Works great now, ….especially after I purchased a GT AX11000 to use while they were being fixed/replaced.

  86. Hi Dong. Thanks for another great review! Will you update this review now that a bunch of firmware updates have surely come out addressing any shortcomings (and new features) noted on the current review? Thank you again.

  87. Hi Dong,

    in different reviews in the internet as well as some comments in this thread I can see that some users set scheduled reboot every day, every other day etc. Some do it to fix some bugs they have, others consider it to improve performance considering how sophisticated this system is (small PC). Also considering this function is available in ZenWiFi itself I assume Asus also assumes it may make sence. Do you recommend scheduling reboots for better operation? If yes how frequent?


    • Yes, I’d set that to be once or twice a week, Nazar. Pick a time that won’t affect anything. The restart takes about a minute.

  88. I’ve just setup the system. Router is connected to the Fiber ISP modem through the cable and then Router is connected to the node through 5hZ-2 backhaul. It used connection type as Wireless Router Mode (Dafault). I wander if it’s correct connection? It seems like schematically I should use AP mode as I have ISP router in between. Pls advise. Thanks.

  89. Hi Dong,

    if I have many IoT devices, 4K streaming TV’s, laptops, tablets, etc. Would I have better performance separating frequencies 2.4Hz for IoT devices and smartphones and 5Hz for 4K TVs and Xbox console? I read some Amazon reviews which point that separating frequencies gave better speed/performans rather than use them combined.



  90. So I’ve finally got my pair, and after fiddling for hours to copy my old setup, the router update (for a reserved IP address) got stuck. Now I’m unable to reach the router web interface anymore, with https://router.asus.com:8443 (and http://router.asus.com) now returning ERR_CONNECTION_REFUSED. The Internet is working, but being unable to reach the router is a real problem
    Any suggestion what to do about it, aside from a reset and starting over?
    I tried disconnecting from power for 2 minutes as I read somewhere, didn’t budge.

      • Thank you Dong.
        I’ve tried that as well, but I’m getting the same “connection refused” error. This isn’t a DNS resolve issue, `host router.asus.com` returns the correct IP address.

          • Tried that, didn’t work. Logging in through the app failed as well. Eventually I’ve reset the router and defined everything again. I minded to back up every once in a while, which was I really good idea indeed it occurred twice more. I think it might have to do with the fact I was making these configuration changes while being far from the main router (connected by Ethernet to the remote node).

        • I had this exact problem when setting up my mesh. I had to reset multiple times and start over. I changed which unit was my “main” router and everything is fine.
          I saved my config, reset both, set up again with the previous unit as main, and had the same problem where I could not log in through browser or app. I reset and switched back and everything works as it should. It seems one unit is not functioning properly.

  91. Hi Dong,

    could you elaborate a little regarding “Multi-gig WAN port with Dual-WAN and WAN link aggregation” as I couldn’t find any specific posts regarding aggregation on your website.

    Say I have two wired fiber modems, one has 100mbps download, 5mbps upload speed and another has 50mbps download and 20mbps upload. Can I connect them both to Asus ZenWiFi AX? If yes what my total theoretical speeds can be for download and upload?


    • You have two options load-balance and failsafe, Nazar. In my XP, the former is only relevant when your two WAN connections are of similar speeds (yours are not).

      • Hi Dong,

        I have 4x 4k TVs, two laptops, one tablet, about 25 IoT devices, 3 smartphones, 4 Apple TVs and an Xbox console. Would I have better performance with separated 2.4Hz and 5Hz where 2.4Hz will be used for IoT devices and smartphones and 5Hz for TVs, notebooks, Apple TVs and Xbox? Or will have them in one will perform equally good? Also does QoS really do any difference? Thanks

    • @Dong Ngo, You can ‘load balance’ the load, so you can for instance send 75% to one WAN and 25% to another. Especially when the WAN speeds are not similar. But my biggest issue with this is that the load balance option will disable QoS.

    • @Dong Ngo, thanks, does it mean it will increase download and upload speeds or speeds will remain the same but only the throughput will increase?

    • @Dror, thanks, this was useful. But I can’t understand how a USB port can be used as second WAN if modem is not 4.5G but fiber with WAN cable out. Can I use two WAN cables in Asus ZenWiFi AX to aggregate from two fiber modems?

    • @Dong Ngo, thanks. But I will have two similar speeds fiber modems, say 100 download and 5 upload, will my download and upload speeds double in load-balance mode or will I only increase throughput? Also can Asus ZenWiFi AX accept two WAN cables for this purpose? (not USB). Thanks

    • @Nazar, you can choose if you want to use one of the LAN ports for this, or the USB port (with a USB to Ethernet adapter).

    • @Nazar,
      You can do 2 things: or connect one fiber modem to one of the LAN ports and tell the router in the configuration he has to use LAN 3 (for instance) as WAN connection; OR you can buy a USB to ETHERNET adapter and connect the fiber modem to that adapter and the USB in the router.

    • @Nazar, I think that depends. For one request it will not increase speed, because that one request will use one of the 2 WANs, but if you have multiple requests, these will be load balanced over both WAN connections and you will be able to use both speeds to the max and that will mean that for your perception you have 2 times the speed.

      • Hi Sven,

        thanks. Say I have 2x 100mbps fiber modems connected in balance mode. When I’ll put a torrent file to download which pretty much fills in the whole throuput, what the download speed will be? In torrent download the higher the speed the quicker it downloads.

          • Thahanks.

  92. Unfortunatly i am unable to connect google chromecast, Google home display(lenovo) to the New netwerk (worked before) they will not connect. Any sugestion is welcome

    • @I.spohr,
      Perhaps change the WPA type? When I used WPA2-personal I could connect my Windows 7 laptop, but when I changed it to WPA2/WPA3-personal I could not connect anymore.

    • @Dong Ngo, Thanks for your reply

      Before the ZenWifi AX, I used the RT AC5300 in combination with 2 Lyra Mini in AImesh configuration without any problems. Now with the new Zenwifi AX in combination with the 2 Lyra Routers in AImesh None of the google devices (Chromecast audio, Chromecast Video, google home mini, lenovo Clock, Lenovo Smart display) connect to the network, I have on all WIFI bands separate SID’s and try to connect the google devices to the 2.4 Ghz Band SID. All my other devices (laptops 11, Tablets 3, phones 7) connect ) distance to router(s) less than 3 metres ( max 6 meter)

      I Did try with 5Ghz-1 and 5Ghz-2 channel aswell – No Luck
      I Did
      – Switch USB mode from USB3 to 2 – No Luck
      – Diabled 802.11ax / Wi-Fi 6 mode – no Luck

      I hope anyone has similar experience and suggestion to solve

      Firmware Version:

  93. Dong, (and Rob please)
    We currently have Xfinity gig service, SB8200 modem and two Asus 3100 routers in mesh config (one router, the other mesh connected via ethernet gig switch). Modem and router are in office at one end of house. Mesh node is in a bedroom to get coverage to two kids on devices for zoom classes, xbox, etc. House is about 2800sf.
    When it’s working well, we get fast speeds on connected devices. From router, I get 948Mbps on my laptop. From mesh, connected via ethernet, I get the same. Wireless is less, of course.
    Problem is with five of us on Zoom/Webex and Netflix, etc. the system is getting bogged down and we are getting slow speeds. Seems the only solution is resetting the modem and routers. We’ve had Comcast out twice.

    A few questions:
    Will wifi 6 mesh solve this problem?
    How many mesh nodes?
    Which vendor?
    From this article, you are rating the Asus tops, but Rob comments On Nov 28, that the Orbi worked better than the xt8.

    Other question:
    Is the XT8 compatible with my 3100 routers? could I use them as additional mesh nodes in different room? That would certainly save the hundreds of dollars invested in those.

    Thanks in advance,

    • @Dong Ngo,
      Thank you for the reply. I’ll read the article. I’ve just set the QOS to “work-from-home” to prioritize online conferencing. We’ll see how that works plus any other suggestions in your article.
      Thanks again,

    • @Dong Ngo,
      Thank you for the article. As noted, set to work from home, so fingers crossed. Additional information regarding SIP. Our Comcast VOIP has a separate router w/ wifi disabled, so I’m not bothering to mess w/ the Asus settings w.r.t. SIP.

      Hopefully last question. Is there way or need to change settings on the mesh node, which is an identical Asus 3100?

      Thanks again,

    • @Marty J,
      well, here’s yet another question. I’m using five of the ethernet LAN ports off the router. Three are showing 1Gbs: Desktop PC, work laptop and a gig switch that distributes to the house. I know that is getting through because the mesh node is receiving and if I plug into that mesh node, I get just shy of full speed.

      Problem: Two are showing 100Mbs. One of those is to a gig switch hooked up to another desktop and the TV. The other goes to feed the Sonos system. It’s less important maybe, but simply puzzling why there are different, at least from the other switch that is transmitting at 1Gbs.

      I’ll need to Venmo you.

      • That’s likely because the TV and the Sonos use Fast Ethernet (10/100), Marty. The speed between a pair is that of the slowest party involved. More here. Also, check the cables.

      • @Dong Ngo,
        Again, thank you. That is very interesting that the slowest client decides the speed. Makes sense. I checked the Sonos line using only my laptop and the speed increased. So that one is good.

        The other, not so good, even when I only had my laptop plugged in, it was still under 100Mbs. Checked the desktop and it’s supposed to have a gigabit LAN connection, but not getting it. Not sure how to check the TV (Samsung). Maybe I’ll let the TV run off wireless instead of ethernet.

        I saw where someone said they checked the connectors, so that is my next step for that line. Curious as to why it would work at all if the connectors were bad. Anyway. Learning lots.


    • @Marty J,

      I’m not an expert. I just used what I could figure out based on my own use. The biggest change for me was moving the main router and modem connection to a better center point in the house and then surround it with enough nodes to ensure good coverage in my home, which is actually pretty small.

      A few things that helped. (1) installing the nodes high on walls and without any blockage between them. (2) running a wired backhaul.

      Now that said, with the firmware I had with the XT8s at the time I still struggled to maintain good connection for all the folks needing to Zoom throughout the day.

      Part of that I think is some loss of speed due to the trend micro software, which I loved and hated at the same time. Part of it, I think, is just that the antennas in the XT8 just weren’t strong enough. FYI, you may have read that I was running four nodes. Even with the Orbi being stronger in regards to transmission strength, I still ended up needing one additional node to make my network as strong as possible in the worst room in the house.

      We now run six folks on Zoom all day with little issue and are happy. I still don’t think the cost is justified, but in these times, we don’t have much of a choice.

    • @Rob,
      I feel your pain. I am trying to tweak the QOS per Dong’s note(s). We’ll see how successful that is this week when we have five on video calls all day.
      Like you said, we don’t have a choice.

    • @Dong Ngo,
      Actually turns out my model is teh RT-AC88U. Eight LAN ports.
      So far so good w/ QOS and other settings.

  94. My home is 6100 sqft and my Internet is capped at 150mbps. My concerns are maximizing speed as well as coverage for my whole house. I need something that is wireless. I don’t have any wired capabilities. I will have around 40-50 things connected to it wirelessly. One day we may have 1 gig internet available but that will probably be a few years. Which mesh wifi 6 system would you recommend? Thanks.

      • Dong,

        What does the “Optimization” button/feature do in the app if you run it?

        If I understand it correctly it will disconnect all nodes and then attempt to find the best connection again.

        I assume this isn’t very useful to the average person with 2 nodes and a wireless backhaul. Am I missing something?

        • It’s unclear what it does exactly, Colin. But your assumption is about right. Don’t mess around with things too much just because you can, you might end up making necessary changes and break the system.
