Asus RT-AX92U Review: The Cute Little Odd One Out of AiMesh

The RT-AX92U is the most compact Wi-Fi 6 router on the market to date.

The Asus RT-AX92U, which came out mid last year, is an interesting case that you probably only find during the transition between two Wi-Fi standards, namely from Wi-Fi 5 to Wi-Fi 6.

On the one hand, this is a cute little tri-band Wi-Fi 6 router, seemingly almost perfect for a small home. On the other, when working as a mesh, its odd specs make things a bit complicated — you might mistake what you’ll get out of it.

In all, if you live in a home of 1500 ft² (130 m²) or so, at a current cost of some $200, the RT-AX92U is a decent standalone Wi-Fi solution, especially if you want to keep your personal space neat and tidy. Just make sure you configure it right.

If you’re thinking of getting a 2-pack or more units to form a Wi-Fi system, though, there are things you should know before pulling the trigger. So, keep reading. At the very least, you’ll know why I didn’t review it until now.

Asus RT-AX92U: A cute compact Wi-Fi 6 router

The Asus RT-AX92U the smallest Wi-Fi 6 router I’ve tested. It looks like a miniature version of the GT-AX11000, taking the shape of a small square box, measuring 6.1-inch (15.5 cm) wide and 2.1-inch (5.5 cm) tall, with four antennas on top.

You can raise these antennas upward for better coverage or collapse them on top of the router to make the whole thing even more adorable. Either way, the router works. By the away, the router is wall-mountable, which is always a nice touch.

A little tri-band powerhouse

Despite the small footprint, the router comes with the usual one Gigabit WAN port and four Gigabit LAN ports. It even has room for two USB ports to host storage, printers, or a cellular modem.

The router has no multi-gig port, but it does have Link Aggregation (LAN 1 and LAN 2 ports), and Dual-WAN allowing you to turn one of its LAN ports or a USB port into a second WAN connection.

On the inside, the RT-AX92U is a tri-band router with non-conventional specs. It’s a dual-band 2×2 Wi-Fi 5 device that has a third 4×4 Wi-Fi 6 5GHz band. You can lump all these bands together using SmartConnect, or you can name each with a separate SSID (Wi-Fi network).

Having two different 5GHz bands is getting common for Wi-Fi 6 routers. The AmpliFi Alien, for example, is on the same board, though it features faster Wi-Fi 5 specs.

As for processing power, the router uses a dual-core 1.8 GHz processor, 512 MB of RAM, and 256 MB of flash memory. It’s not the most potent router I’ve seen but still quite impressive considering its tiny physical size.

Asus RT-AX92U’s specs

Again, the RT-AX92U is one of a few tri-band routers on the market that use one Wi-Fi standard for each of its three bands.

When you use multiple units in an AiMesh setup, it will dedicate its fastest Wi-Fi 6 band as the dedicated backhaul that links the units up. As a result, performance-wise, it will be similar to a Wi-Fi 5 system.

Specifically, as a single router, current 2×2 Wi-Fi 6 clients can expect to connect at 2.4Gbps, while 4×4 Wi-Fi 5 can get up to 1.73Gbps. As a mesh, all wireless clients will get the ceiling speed of 867 Mbps. These are theoretical speeds, and real-world sustained rates will vary — more below.

Asus RT-AX92U’s photos

The RT-AX92U 2-pack set comes in nice packaging.

The RT-AX92U is available as a single router or a 2-pack mesh system that includes two identical units.

The antennas can stand up or collapse on the routers’ top.

The RT-AX92U has the usual five Gigabit network ports, including one WAN and four LANs.

The router also has two USB ports, one USB 2.0 and one USB 3.2 Gen 1.

If you think the RT-AX92U is cute, that’s not an exaggeration.

The familiar setup process, settings, and features

At its core, the RT-AX92U is like any other Asus routers. You can set it up using its web user interface or the Asus Router mobile app.

I prefer the former, which involves connecting a computer to it and then opening up a browser. You’ll then automatically run into the initial setup wizard that walks you through the setup process. Alternatively, you can always reach the router’s interface by navigating the browser to its default IP address, which is 192.168.50.1 or router.asus.com.

The RT-AX92U shares the same web interface as other Asus routers and has the same set of network settings and features.

Most notably, it has AiProtection that includes free online real-time protection and a set of Parental Control settings. There’s also Adaptive QoS that allows for quicky prioritize internet traffic for different purposes.

What’s more, the router even has the support for WTFast Gamers Private Network. Available in only select Asus routers, WTFast allows the router, hence the network it hosts, to be part of a proprietary VPN designed to deliver the best online gaming experience given the broadband speed.

The support for WTFast makes the RT-AX92U even more like the mini version of the GT-AX11000, which is a full-featured gaming router.

The RT-AX92U has Game Boost, a venerable feature that gives gamers an edge.

Asus RT-AX92U: Not a real Wi-Fi 6 mesh router

While quite straight forward as a standalone router, as a mesh system, the RT-AX92U is quite odd. That’s because it dedicates its second 5GHz band, the 5GHz-2 that is, as the dedicate backhaul. That band happens to be its only Wi-Fi 6 band.

A Wi-Fi 5 mesh system at its core

As a result, Wi-Fi clients can only connect to it via the Wi-Fi 5 standard. In other words, when using a 2-pack as a mesh, which Asus calls AiMesh AX6100 Wi-Fi System, the RT-AX92U is about the same as a regular Wi-Fi 5 system.

(Note: Like all tri-band AiMesh systems, you can turn the RT-AX92U’s 5GHz-1 band into a non-dedicated backhaul to also use it for clients.)

Having a strong backhaul, though, you can probably place the hardware units further apart to deliver a broader coverage — Asus claims the mesh can handle up to 6000 ft². But in terms of speed, the system’s ceiling speed will cap at 867 Mbps. Real-world speeds will be much lower.

That said, if you have a Gigabit-class internet, as a mesh, the RT-AX92U will not be able to deliver it in full unless you use it via a wired backhaul.

The hardware units of a 2-pack RT-AX92U are not pre-synced out the box. You’ll have to add one to another to form an AiMesh setup manually.

Non-pre-synced hardware, wired backhaul support

I tested a 2-pack of the RT-AX92U and found that out of the box, the hardware units are not pre-synced, like the case of the recently-released ZenWiFi AX. All this means you’ll have to add the 2nd unit to the first to form a mesh manually, the way you do any AiMesh router.

And adding the second unit, or any other AiMesh router for that matter, to the mesh hosted by an RT-AX92U proved to be a bit problematic. I had to try a couple of times. The lesson I learned is:

  • If you get a 2-pack and set up both units as a wireless mesh system from scratch, you’ll likely have no problem. You’ll note that in this case, the 5GHz-2 Wi-Fi 6 band automatically works as the dedicated backhaul. Asus does this making a separate SSID for this band and hides it from clients. More on this here.
  • If you have used just one unit as a single router and now want to expand the coverage, chances are adding another node via Wi-Fi will fail. Instead, you should connect the node unit’s WAN port to the router unit’s LAN port, using a network cable. Or you can reset the router unit and set them both from scratch.

I’d say using wired backhaul is the way to go. Because in this case, you can make use of its Wi-Fi 6 band.

Like other Asus routers, the RT-AX92U has all you can think of when it comes to USB-based features.

Asus RT-AX92U’s performance: Fast, but a bit of a rough ride

I tested the RT-AX92U first as a standalone router and then as a wireless AiMesh system. After that, I also used it as a node via wired backhaul with the GT-AX11000. In all, the router worked out, but not without some issues.

Wi-Fi 6 band could be better

The most noticeable issue is the 5GHz-2, which is its only Wi-Fi 6 band. Despite its high-end 4×4 specs, I had a hard time getting a fast and reliable connection from certain clients.

When using the RT-AX92U as a standalone router, my 2×2 Wi-Fi 6 client (fastest available on the market) never connected to it at its top 2.4Gbps negotiated speed, but only at 1.2Gbps.

And I tried everything, such as forcing the band to use only 160MHz channels, using the Auto setting as well as picking a channel manually, one after another.

For this reason, you’ll note that, on this 5GHz-2 band, my test 4×4 Wi-Fi 5 test client delivered better performance than 2×2 Wi-Fi 6 counterpart.

However, this band didn’t work well with all of my Wi-Fi 5 clients. On the one hand, my Asus PCE-AC88 card, which I used to test the router at a close distance, worked consistently well. On the other, few Google Pixels, iDevices, and most other Wi-Fi 5 clients had dismal speeds, even when connected at full bars.

The bottom line is when you use this band to serve clients (and not as a backhaul) make sure it works only with Wi-Fi 6 ones.

With most other clients, the speeds fluctuated a great deal. I tried both routers in the 2-pack set, and both had the same issue.

The RT-AX92U’s 2.4GHz band delivered the same performance as that of most routers. There was nothing of note here.

Sightly faster than a Wi-Fi 5 mesh counterparts

I tested a 2-pack RT-AX92U as a mesh via a wireless setup. In this case, from the clients’ perspective, it was no longer a Wi-Fi 6 system, but only a 2×2 Wi-Fi 5.

That’s because the 5GHz-2 band now worked as the dedicated backhaul. And the scores showed just that.

The router unit of the system had the sustained real-world speed about the same as any other 2×2 Wi-Fi 5 router, averaging about 606 Mbps at close range and some 413 Mbps at long range.

The satellite (node) unit, which I placed 40 feet (12 m) from the router, however, topped the chart, registering more than 560 Mbps at the close range and some 500 Mbps at the long-range.

It’s safe to say; the 4×4 Wi-Fi 6 dedicated backhaul plays an essential role in RT-AX92U’s mesh performance. Generally, you can expect mostly full speed of the system’s 2×2 Wi-Fi front-haul, which caps at 867 Mbps on papers.

Good range, excellent add-on AiMesh node

I tested the RT-AX92U for a week as a wireless mesh system, and it proved to be quite reliable. Again, at times, some Wi-Fi 5 client connected at slow speed, but most other had no issues at all. There was no disconnection.

As for coverage, a single RT-AX92U router had about the same range as the Netgear RAX40 in my testing, which was not the best I’ve seen but wasn’t too shabby, either. With the two-unit combined, you can expect to cover some 4000 ft² (372 m²), but your mileage will vary depending on the layout of your home and the type of walls.

By the way, I also tried the two RT-AX92U units as add-on nodes to my GT-AX11000 router, using wired backhaul, and they have been working quite well.

Fast NAS speed

Considering the RT-AX92U has no multi-gig port, I didn’t expect much from it in terms of network-attached storage performance. But the router did well.

I tested it with the SanDisk Extreme Portable SSD, and via a gigabit wired connection, it registered the sustained copy speeds of almost 70 MB/s for writing and more than 112 MB/s for reading.

I already recommend getting a real NAS server. Still, if you want to do some casual network storage, the RT-AX92U will do, especially considering its vast amount of storage-related features.

Conclusion

At the core of it, the RT-AX92U is a Wi-Fi 6 router that can only make a Wi-Fi 5 AiMesh system, despite the fact Asus released it as its first Wi-Fi 6 mesh system. At launch, the router was quite buggy, which is partly the reason why I waited until now to review it.

Now, after numerous firmware updates, the RT-AX92U is much better. But there are still things I can’t put my finger on. The problematic Wi-Fi 6 band is an example.

That said, still, I’m comfortable recommending it as a single router — just make sure you name the 5GH-2 band separately and use it only for Wi-Fi 6 clients. As an AiMesh member, though, the RT-AX92U works best as an add-on node to another tri-band router, like the GT-AX11000, via a wired backhaul.

And that’s because, for a wireless system, you should consider the newer ZenWiFi AX, or even the ZenWiFi AC, instead. After all, a pure RT-AX92U-based wireless mesh won’t give you significantly better performance than a Wi-Fi 5 system anyway.

  1. Hi Dong – congrats on the great site. I have a new ax86u as my main router. I have 1gb wired backhaul to the upstairs roof where I need to replace my trusty Cisco 1252agn ap with an AI-mesh Wifi 6 ap or router. But! There’s no power up there – I need to use the existing POE injector for the Cisco or a new POE injector/splitter combo like the Planet POE-171/S, which will do 19v. Is there an obvious choice for this AP? Anything in the Asus Wifi 6 world that will do POE? Any Asus POE splitter? There used to be a thing called the Asus ES-101, but that seems defunct now. Any advice much appreciated.

  2. Hey Dong,

    I’ve been a follower of yours for a year now, and really love the first-class content you deliver to us.

    Here’s my situation:

    I’ve got a cabin home + garage / game room that are 60 yards apart. The garage is full of steel. The fiber optic laid (only 100Mbps) is coming into the Garage, and I want to extend the network to the Cabin Home.

    I have Cat7 Ethernet buried to connect the two buildings, as well as a Ubiquiti NanoStation on either end.

    The NanoStations have worked well for us in the past when beaming the previous DSL network (5Mbps), but now that we’re upgrading to the fiber speeds which are fantastic for the North Woods location of Wisconsin, I want the most robust, future-proof setup possible.

    I’m thinking about pairing two ASUS WiFi 6 routers via Ethernet, and part away from the Ubiquiti NanoStation setup.

    – I want to be sure they each (2 networks, one for home, one for garage) produce 2.4GHz + 5GHz networks, and support WiFi6 devices.

    – The range should ideally be 1,000 sq ft for the garage (network1), and 2,500 sq ft around the cabin (network2).

    I’m thinking either two Asus RT-AX92U , or two Asus RT-AX86U . . .

    Both of these seem like overkill, but I want to have it set up correctly NOW to accommodate the event that we increase our bandwidth speeds in the future.

    Please let me know your thoughts! I highly appreciate your time.

    • Thanks, Chris. Happy to have you. In case, I’d recommend the XT8. With the wired backhaul you have, it’ll work out great. But yes, any dual-band AiMesh set will do. Good luck! 🙂

  3. Hi Dong, some time ago I followed your advice and added the GT-AX11000 to twin-pack of AX92U’s to install an AiMesh network at home. The GT is in the living, wired to 1 AX upstairs, wirelessly to the other AX in the kitchen. Every time I check which devices are linked to which “machine”, I notice that nearly everything connects to the AX’s. For example: I sat down within 4 meters from the GT with my laptop, and switched the wifi on it off and on again. Surprise, it connects to the AX92U upstairs! Can you give some advice how to fix that? Seems a bit of a shame that of my 14 devices, only 2 connect to the GT, one of which is the doorbell chime 😂

    • Under the “professional” settings you can tweak the signal strength at which it will try to hand off devices from one node to another. It’s possible, though, that you have the nodes closer together than they need to be — maybe you don’t even need one of them at all? If signal strength on the client is good, throughput is good, reliability is good… it shouldn’t really matter which node they actually connect to.

      Reply
      • With the most recent firmware upgrade you can actually bind anything connected to your aimesh system to a specific node so it actually can’t jump to other nodes.

        I did this on a few items in my system which consists of three AX92u’s with stationary equipment that does not need the benefit of mesh handoff moving around the property such a desktop computers, wifi printers, thermostat, a split system in a garage, etc..

        To do this get the most recent firmware, click on the new AiMesh tab, find the device you want to bind to a specific node, then click on the little circle within the device box that looks kind of like a chain-link. From there you can actually specific with one of those nodes you want to bind it to. You can undo this and change nodes later just as easily and works great.

        There is also another little circle next to the binding circle where you can reconnect devices if you are having some sort of weird connection issue just FYI. The new firmware helped a ton. Not perfect, but way better.

      • Hi James,

        Thanks for your advice. But I already did that, following one of Dong’s articles Changed it from -70 to -67. I just find it odd that the laptop seems to connect to the node 1 floor up, and not to the router “at my feet.”

    • It can be a lot of things, Henk. Chances are your home is small. Try turning off the AX in question to see how things change, you’ll be able find out the issues.

      • Hi Dong,

        I’ll do that but for the record, for European standards my house is quite large (60 ft long) and in one way or another most devices link to the AX’s. If I follow your lead, where do I have to pay attention for?

        Thanks Henk

        Reply
        • Henk,

          Handoff generally doesn’t take place if the current connection is good (and the threshold for “good” is rather low). However, when you toggle the Wi-Fi setting on the device, it generally should pick the broadcaster with a stronger signal (which might or might not be the closer one). So when that doesn’t happen, check the following:

          1. The distance between two broadcasters is just too close (they should be at least 40 feet apart if there’s nothing in between).
          2. There’s a line of sight between the device and the father broadcaster, and something in between it and the closer broadcaster.
          3. The Wi-Fi settings of the closer one is not compatible with the client.
          4. Something is different about the client itself, try another client.

    • Hello Dong, Congratulations on this website, missed you on CNET. I have the 2-pack RT-AX92u setup using 1 gig ISP with CAT6 backhaul – everything is running great. With covid, kids came back home and now I have 55 devices connected, some on WiFi6 and 2-3 Zoom meetings at the same time. Asus GUI shows memory at 95% – is this an issue? Also discovered a dead spot and need another node. See above poster used your recommended GT-AX1100 which is nice but that is expensive unit not rated as high as AX88u or even AX86u. Should I buy another AX92u or make one of these my main router? thanks

      Reply
      • Thanks, Marlon. Glad you found me here! 🙂

        I wouldn’t worry about memory usage — memory is to be used. But generally, that happens when you turn on multiple features. Since you have wired backhaul, you can get another dual-band unit, like the RT-AX3000, but the RT-AX8xu is great. If you get a higher-end unit, though, like the RT-AX86U, or GT-AX11000, then make it the main router. But another RT-AX92U will work out great, too. In other words, they all will work out great but if you get another 92U unit or a low-end dual-band one to use as an additional node then it’s less work.

        • Thanks for your advice. You have a great site with wealth of information here. Do miss your review videos 😂, they were very funny and made my day.

  4. I thought I’d just leave a quick message because the firmware update that came out yesterday may significantly change some opinions/functionality on the 2 pack. I got the 2 pack of the 92u’s a few weeks ago and has worked well. It could work better if I relocated one of them, but need to run a wire to get it out of the basement.

    Anyways, the firmware update has actually opened up a ton of new features and now has the option to use only wired backhaul where it can then do the “smart connect” feature and combine ALL 3 frequencies together. You can still separate them out on separate SSID’s, but before the most you could do is combine 2.4 and 5ghz-1.

    Additional features for optimizing the mesh network have been added along with a number of other things.

    I do have a 3rd Asus ac68u connected via wired connection out in the garage, but the updated firmware for this unit has not come out yet so don’t get full functionality of the new firmware on that node yet, but overall it seems like everything else is working even better now. Might check it out!

    • Thanks for the heads-up! I got an email from Asus a few days ago, about how I should apply a “security critical update”, but when I checked their website the latest firmware was from May or something. It must not have been quite ready yet. One thing to note for other owners on the page, I think something changed on the server side so the auto-update function isn’t able to apply this one, you’ll have to download and apply it yourself.

    • Brian, did you do anything special while upgrading? I downloaded the new firmware from the website, then used the firmware management page on the main router to upload to the nodes first, then the main router. I rebooted everything but the main router couldn’t see the nodes anymore, so I used the red reset button to reset the nodes and put them back in mesh-node mode. That let me see them to add, but the add process keeps failing. I tried resetting the main router too, but the adding process still fails at the end every time.

      For now, I put one of the nodes in AP mode (I’ve been using it with wired backhaul) just so I could get the house online again, but I don’t know what to do next. I guess I can downgrade back to the 384 firmware?

      Reply
      • Hey there! I didn’t really do anything special. When I was on the the web interface it showed that the main router needed a firmware upgrade. I just pressed the button and it upgraded it automatically. It did not automatically upgrade the other node though. I just manually uploaded that to the other node and it all worked just fine. Nothing special at all.

        Reply
        • Thanks for following up. I don’t know why the initial upgrade caused nodes to show as “offline”, but I did figure out my problem post-reset — eventually, but it took *hours*. I made a post about the issue on SmallNetBuilders and Asus’s official forums.

          The short version is, if you do a factory reset, your device clock goes back to May, and can’t be fixed until it gets connected to the internet. I spent all day trying to configure my mesh offline. Once I figured out that it needed to see the internet, I was able to rebuild my mesh in a few minutes. Moral of the story: always put your AP on the LAN before adding a mesh node.

          • That makes sense, James. Thanks for sharing. And yes, getting the router unit set up properly is the first part of building and AiMesh.

    • Brian,

      Concerning Tri-band smart connect over wired backhaul.
      firmware: 3004 386_40451 latest as of writing.

      I have been trying with this new firmware on my 2x ax92u set to use wired backhaul and smart connect on ALL 3 channelsjust as you said, but am at a loss at how to actually achieve that.
      Have done so many resets and the whole family is working @home. Getting tired of it.
      note: The wired backhaul I use is a stable CAT5E through a TP Link 16port desktop switch, NO filtering, just 1Gbit switch with internal 32Gbit capacity.

      The thing is:
      – i reset the router and node.
      – setup the mesh in web interface.
      – set the wired backhaul as 1st preferred on router. Give it 5 min.
      –> It then only allows 2 channel smart connect. The only way I get 3 channel smart connect is to reset the router and configure without the node==without aimesh.

      And also I noticed this new feature: Setting the Aimesh as wired backhaul in “Aimesh->System Settings->Wired Backhaul=ON”.
      It just completely disables the mesh node.
      Resetting the node does not let it get rediscovered.

      Pulling the cable from the node:
      I then reset the router as single router. No mesh options set, so triband smart connect is available again.
      Then set up mesh over wifi, plug in the cable and select wiredbackhaul as 1st preferred does still not enable three channel smart connect.

      I tested so many possible ways, also the Adroid app with total conflicting settings.

      So, may I ask, how did you manage to get it working or at least were able to test it?

      PS all the time the router was connected to working ISP 300Mbit stable Cable connection. NTP working fine. I want wifi 6 for my NAS with ZFS/BTRFS/TimeMachine storage and less cables around the house. Coppercable dependency is a flaw to humankind in my opinion which we need to sort out of the system ASAP.
      PS great reading on this corner of the net. Thx all.

  5. Hey Dong,

    Great write up! Just curious, when running both ax92u together did you notice the RAM usage was high? I’ve been seeing 93% usage and worry about future if it will last. What configuration would you recommend while keeping security and performance?

    Reply
    • That’s likely because you have too many features turned on, Coness. But RAM is to be used, as long as you don’t need more than what the router has, it’s fine.

  6. Its confusing that you say this isnt a Wifi 6 mesh router, but in your other post about AiMesh you say that you can make 5ghz-2 available to clients by unhiding it. Even though this is no longer a “dedicated backhaul”, I dont see how that makes this ax92 *not* a wifi 6 mesh router. Also, along the same lines, if I use the ax92u as a satellite to an AX-11000, wouldnt the satellite still have the same issue? (I would have to make 5Ghz2 visible to clients), or AX clients would need to connect to the primary router .

    Can you clarify this? How is using the AX92u with the AX11000 really any better, if I still dont have a dedicated (wireless) Wifi 6 backhaul? If dedicated backhaul is the “end all be all”, then maybe the AX92U is kind of a non-starter.

    Reply
    • I didn’t say that, Billy. I said it was not a “real” mesh router. The keyword here is “real”. Meaning it’s still “kind of” a mesh router. And in working with the GT-AX11000, it’s still better than using a dual-band router as an AiMesh node.

      Reply
      • Right so if it supported Wifi 6 on 5-ghz-1 Im assuming that then you would say it was a “real” mesh router. But in your article you say you will never get Wifi 6 speeds in mesh mode. But if you unhide 5ghz-2, then you AX clients should get their normal speeds.

        See what Im saying, you do directly say that in mesh mode Wifi 6 clients cant connect. It might be better to say, you have to unhide 5ghz-2 so they can connect. It would be more clear than saying “you will only get wifi 5 speeds” when used as mesh. This doesnt seem to be the case.

        • Wi-Fi 6 clients can connect to Wi-Fi 5 broadcasters just fine, Bill. The unhiding the 5 GHz-2 is just my trick which is not a normal way you operate the RT-AX92U in a normal manner. Also, in this case, the backhaul link will be severely affected since it’s no longer dedicated. I got your point but I think you’re splitting the hair here. 🙂

          Reply
          • Obviously you want wifi 6 clients to connect to the 5ghz-2 radio on the ax92U or they will only get wifi 5 speeds.

        • I think Dong has an article about this: if you use a wireless backhaul and it’s not dedicated, you get “signal loss” which means your maximum performance is halved. The wireless frequency (channel) that each band uses is a shared medium and only one interface can use it at a time. So, either a client is “talking”, or the router is, and the other one has to wait. If you have multiple clients clogging up your backhaul band, your performance could quickly degrade to be worse than just keeping everybody on 5Ghz-1.

          If you really want to use the pair with a wireless backhaul band *and* allow clients to connect at WiFi 6 speeds, you can try it and benchmark your real world performance, but I suspect you would have a better experience leaving 5Ghz-2 as dedicated backhaul. (If you run experiments, I’d love to hear about it!)

          • Unfortunately, I dont have any WIFI 6 clients to test with. But I did look up on ASUS product list and noticed there are no other ASUS routers capable of wireless backhaul at all besides this and the GT-AX11000. Which to me seems to be saying TRI band is sort of pointless (unless you buy 2 expensive AX11000s or the XT8, and AiMesh is really just a wired solution, which doesnt seem very “mesh-like” to me, since wiring routers together is as old as the hills and not mesh technology or new in any way. Given this, I may end up returning my AX11000 and replacing it with the dual band AX86U since I cant see wireless mesh benefitting me in the near term and Im not running cables through my house.

          • I don’t know where you’re seeing that other AiMesh routers can’t use a wireless backhaul. I wound up getting a 2-pack of AX92Us and the wireless backhaul is fantastic. It’s using the 5GHz-2 band (AX standard) and punches right through our troublesome floors to make a stable gigabit-plus connection, compared to 40Mbit (!) with my old powerline kit. In the future, I may pick up another AX92U or even the fancy AX11000, to get better coverage.

            Is there a specific “AiMesh” badged router that says it won’t support wireless backhaul? This page lists something like twenty models as “applicable” for dedicated backhaul, and explains how they can even support it with a dual-band participant.

          • Responding to your comment below. My statement is that there are only 2 routers that support wireless backhaul this one AX92U and the GT-AX11000. This is clear from the ASUS website. Since the AX92U does not support WIFI 6 with a dedicated backhaul, that means only the XT8 and GT-AX11000 do. Which means theres not much point in having an ASUS triband router at all for WIFI 6 in a mesh configuration unless you either want to spend a ton of money, dont need WIFI 6, or want to wire your clients.

            Its interesting that you cant seem to understand my posts, when they are very clear. And based on this post and the ASUS website. I guess theres something lost in translation.

          • Wireless backhaul is not necessarily dedicated, which is available only in tri- band routers. And no, I’m not nuts. Read the post, Billy.

          • I figured out where the miscommunication happened: from your other posts, I did not understand that you meant specifically *WiFi 6* routers, with dedicated backhaul. There are only a handful of routers anywhere that support WiFi 6 clients, the standard isn’t even finalized yet and probably the only “popular” / mass-market client is the newest iPhone. We kept talking past each other because I was saying that most AiMesh routers support dedicated wireless backhaul (which they do) without considering which ones have WiFi 6 support.

            While I did buy a router with a WiFi 6 chipset, I did so knowing that I only plan to use it with WiFi 5 clients, and even if I buy another mesh node that’s WiFi 5-only, it was still a good value at the price I paid. That’s my advice to everybody: in 2020, at least, treat WiFi 6 as a nice-to-have novelty, but don’t spend a ton extra to get it.

          • Yeap, James. Reading the words that appear in front of you is different from looking for stuff that matches what’s already in your head. 🙂

        • This router is a full wifi6 router, just unhide the backhaul channel. Clients can then connect to the backhaul channel which supports AX. The backhaul channel has loads of bandwidth, using it won’t mess up the front haul channel. I can run 2 simultaneous speed tests, one on the front haul, the other on the back haul without any slowdown. My internet speed is 900mbps up/down.

          Here’s the speeds i get:

          Wifi 5 – 400mbps
          Wifi 6 – 650mbps

          The idea of this mesh network is to keep all the Wifi5 devices separate. If you have a specific need for wifi 6 allow those devices to connect to the wifi6 channel (set it to AX only).

          Whilst most people would prefer to only have one SSID for a clean look having the 2 bands really helps with congestion. It’s non existent on our network with no buffer bloat.

          We have torrents running, xboxs via ethernet, wifi 6 phones, wifi 5 laptops, wifi 6 desktops, old 2.4 ghz smart devices and printers. A mish mash of about 20 devices and this router delivers top tier performance every time.

          On top of that we have full coverage in the entire house and front and back garden.

  7. I’ve been putting off pulling the trigger on a new mesh kit for a couple weeks now, and today I noticed that this one went on sale for right around 300 EUR. I had been leaning towards the Orbi RBK50, but now I’m not so sure. You seem to be a big fan of AiMesh generally, plus I need at least one “leg” of wireless backhaul and I don’t have any WiFi 6 clients yet, so this seems like a good fit. I’ve read this review and your AiMesh writeup, but it looks like you haven’t covered Orbi as much.

    That said, do you have a strong feeling one way or the other? I don’t need a lot of “features” (parental controls, remote management, IoT devices/smart speakers, guest network) and my internet is currently 150/30 so raw speed is not a huge concern either. My number one priority is stability — consistent connections and seamless handoff. If I don’t have to *think* about my network for the next 3-5 years I will consider this money well spent.

  8. I wonder if you can help… I’ve got a AX11000/AX92U setup with channels that look like this:

    https://1drv.ms/u/s!Ai94da6gxaGUvM9h8rY4Ee-Ih5J9Mw?e=XBB1np

    I have two questions:
    1) how do I get the AX92U to move down to channel 36? I can move all the other channels around, but that one moves on its own and I can’t find a way to control it.
    2) no matter what the settings, the routers refuse to use more than 40MHz. Currently, I have it set to 80MHz (not 20/40/80), but it just ignores me. What else can I try to change this.

    Reply
    • I’d recommend leaving the setting for channels at Auto, Rick. What you see there might change significantly at other times. It’s best to let the router deal with that by itself. As for the channel width, that depends on your clients, too. If you have a client that doesn’t support the 80 MHz, then the router will use 40 MHz.

  9. Hi again. Following your reco I tend to go for Asus. As I don’t need wireless backhaul and don’t have any 4×4 clients I consider both RT-AX92U and RT-AX58U . Which one is a better option? Btw, how to explain the that RT-AC92U performed better with WiFi5 client at longer distance than at shorter?

  10. I recently purchased the RT-AX92u mesh set and cannot obtain full Internet speed of 940Mbps. The max I get wired on the LAN port is 540Mbps, but if I connect my laptop directly to the Spectrum modem I get the full 940Mps. I also think this is the reason my max wireless speed is 440Mbps. I have factory reset both routers and reversed them with no luck. Asus support has no idea after submitting configuration and debugging logs. I also have a brand new Wifi 6 Killer/Dell XPS laptop. Have you heard of any issues with this model?

      • Yes I already tried that with no change. Could there be a compatibility issue with the Spectrum modem model E31U2V1?

        Reply
        • Not that I know of, Mike. My guess is might be the WAN port has issues (my Internet is quite slow so I didn’t run into any problem during testing). That said, try moving the WAN function to one of the LAN ports and see if that fixes it. You can do that in the WAN section of the web interface.

  11. Hi Dong, I followed your lead and purchased an GT-AX11000 to use as the main router for the two AX-92U’s I have. I placed the GT-AX11000 on the first floor near the staircase (the most central spot in the house) and made a wired connection to the AX-92U in the living as the first node. And a wireless connection to the second AX-92U in the kitchen. When I open my router app, I see that all clients connect to the two nodes, and none to the GT-AX11000. Do I then use the full potential of the GT-AX11000? (on the ASUS site they state that the nodes use the full potential of the router)
    I can swap the 11000 on the first floor with the 92U in the living. They will be connected via an ethernet cable. Would I benefit from that?
    I hope to hear your take on my two questions. Many thanks. Henk

  12. It is frustrating, right now I only have the 2 92us, the one in wireless router mode is in the cupboard but as feared clients are connecting to it when they really shouldn’t. Unless I have missed it there is no way on a 92u to turn wifi off on the unit?

    Last night I tested upstairs and 8 times out of 10 my S20 Ultra connected to the boxed in main unit, with (according to wifi sweetspots) a connection speed of circa 200mbps and signal circa -65 to 70dBm, the other 2 times it connected to the lounge node with 650 mbps and signal of -50-60dBm. I have played with the roaming setting which just not seem to work at all.

    Reply
  13. Thanks, your review and comments are much appreciated. Decided to go with the 92us and get a 3rd one for upstairs.

    Out of interest you say in the review that….. ‘By the way, I also tried the two RT-AX92U units as add-on nodes to my GT-AX11000 router, using wired backhaul, and they have been working quite well.’ How did you configure that ? Operation mode, WiFi modes etc?

    I setup the 92us today on wired backhaul (main unit connected directly to FTTP cabinet acting as modem/router too, 2nd unit replacing ax8 in the lounge). Wired backhaul works fine but I’m still not seeing full WiFi 6 on the 2nd band and despite it showing as connected wired I’m still getting the ‘Asus 5g-2 is now used as dedicated WiFi backhaul under AiMesh mode.’ message which I was not expecting once they were hardwired.

    Speed seems good though and getting comparable to the ax8 (circa 800mbps in WiFi sweet spots apps). That is on a WiFi 6 enabled client. Extra 92u for upstairs coming tomorrow…..

    Thanks again, great site 👍🏻

  14. Leaning towards the rt92u as it it tri-band and I do have some wifi 6 clients so in wired backhaul mode it offers something that the AX8 does not?

    Reply
  15. If I decided to go with 3 units with one in the cupboard (with wifi off maybe) would there be any benefit to sticking with another 92u unit or would the cheaper AX56U work too?

    Other option I am wondering about is if the Netgear RAX120 would make a difference over my current RAX80 in the one or 2 marginal wekaspots that I have. The improvement would not have to be huge to make the difference probably

    Reply
  16. Thanks, I just figured there may a chance of the signal in the cupboard still being connected to if it still had a reasonable signal coming through and my devices might ignore the better signal elsewhere?

    I’ll check that out, was thinking I could go with a 56u in the cupboard and put the the 2 92us as the nodes. If I have to buy a 3rd unit.

    Thanks again.

    • Multiple broadcasters, when placed far apart, help reduce the load on each individual one, Neil. With wired backhaul, you can use any of the AiMesh routers. In fact, you might want to consider the ZenWiFi AX Mini.

  17. Timely review thanks, I just picked up the 92u twin pack but am yet to open and install it. Do you know if it is possible in an Asus mesh setup to have wifi deactivated on the main unit.

    I want to go with wired backhaul as my house is hard-wired with cat 6, however my cabinet and the origin of all of the ethernets is stuck away in an under the stairs cupboard which is hardly the best place for any router. So I’d want 1 unit in the cupboard with wifi off feeding ethernet to 2 nodes elsewhere in the house.

    Reply
    • Yes, you can, Neil. That’s in the Professional tab in the Wireless section. But disabling Wi-Fi in the main router unit is not necessary and will not help with anything.

  18. Hi Dong, thanks for replying so quickly. I read your take on the powerline with regards to WiFi 6. I just did not know if I could mix wired and wireless backhaul. So thanks for that. May I assume that your advice for the AX-11000 rests on more range, compared to adding a third 92U? Because if I understand it correctly, when using the AX band for backhaul it is not very clever to connect clients to that band as well. So in my case I can’t use the AX band since I’ll connect on elf the nodes wirelessly. Or am I missing a point here? Thanks again and greetings form Holland

  19. Good morning Dong,

    I wish I would have read your review before I bought the twin-pack of RT-AX92U. I did quite some reading on it, and did the “help me choose” on the ASUS site multiple times with different parameters. I specifically chose the AiMesh i.s.o. the Zen Mesh as a result of that. Basically they promise you the world, and I find it somewhat disappointing. It lacks range, and even when I set the backhaul to wired, my iPhone 11 Pro drops the connection with the wifi-6 band all the time when I connect with it as the only client.
    As you mention it is not even a real wifi-6 mesh router. I have since then read quite a bit of your articles, but I can’t put my finger on the sore spot over here in my situation.
    If I want better coverage in my house, I will need an extra node. (it only has 2 floors but is quite spread out (60×40 feet) It will be difficult to accomplish getting that third one wired. So after reading up on it it seems that I have a few options.
    1. Send it back and buy another system, but which one?
    2. Add an extra router / node either wireless backhauled, or I’m willing invest in backhaul via a Powerline adaptor and hooking it up to that via an ethernet-cable.
    If I go for option 1, I don’t really know where to start anymore.
    If I go for option 2, would buying an extra RT-AX92 do the trick (with or without powerline backhaul?), or should I go for the RT-AX89X or ROG Rapture GT-AX11000 and make that the main router and reconfigure the two 92’s as nodes? (again with or without powerline backhaul for the 3rd machine?)
    Could you share your light on this, because I’m running around in circles at present. I’ll be very grateful. Best regards Henk.

    Reply
    • Better late than never, Henk. Happy to have you here.

      A couple of things.

      1. Make sure you upgrade the RT-AX92U to the latest firmware. In my XP, it helps.
      2. Range is a very tricky issue since it depends a lot on your environment, and not just the size of your home. More on that here. That said, a different router might NOT improve in this regard.
      3. Powerline is generally too slow for Wi-Fi 6. More on that here.
      4. In your case, I think it’s best to get a GT-AX11000 as the main router and use the other two as nodes, vis wireless or wired backhaul (you can mix that.)

      Hope this help.

  20. Hi Dong,

    I have the ASUS ROG GT-AX11000 as my main router. I wanted to add a tri-band router to reach the far corners of the second floor of my home. Do you have a recommendation between the RT-AX92U and the RT-AC5300.

    Reply
  21. I was in agreement with you until mine stopped allowing me to connect to all 3 bands after the last firmware update. I had read your reviews including the one you referenced here which were most helpful in my decision to purchase the tri-band ax92u. Going to reset my mesh and setup again in hopes it resolves my issue and let you know.

    Reply
    • Try it with a different client, Mike. As I mentioned in the review, this router’s 5 GHz-2 band had issue with certain Wi-Fi 5 clients. Configuring that band to make sure it works in the compatible mode will probably help.

  22. Hey Dong, Been running a single AX92U in mesh with my GT-AC5300 and I suspect the recent firmware has changed the wired back haul settings for the worse. The GT options for my mesh are checked for wired but it will not let me connect to the 5G-2 as I could when first purchased and set up. After checking with ASUS support it appears the AX92U decides which to use wired or wireless as it see’s fit. Here is the support page link.

  23. Hi Anthony, I researched and debated this question too. The RBK852 was also my choice. Good parental controls, functional admin web interface, malware, can reduce wifi output power, fast with wired Ethernet backhaul, and lots of extra Ethernet ports. I don’t I will be missing much with Wi-Fi 5 vs. 6. Have had for a few months and happy with the performance. Thank you for your input. David

  24. Hi Dong,

    Considering buying either the 2pack of these AX92U’s, or buying two AX52U’s. In either scenario, one would be the router, and the other an AI Mesh node via Wired Backhaul. Since I’m using wired, is there any reason to stay away from the AX92U’s and go with the AX52U’s? I have a few WiFi6 iDevices, and am looking to maximize my 1GB Fiber internet connection. I would put the WiFi 6 devices on the 5G-2 band, and the rest of my high bandwidth WiFi5 devices on the 5G-1 band, and then the IOT devices that use 2.4Mhz on the 2.4-1 band. Planning to cover about 2500 Sqft over two floors.

    Only thing scaring me is that I’m reading a number of people complaining about random reboots/WAN drops on the 92U, but mostly from the first couple of months of 2020. Wondering if that’s stabilized with recent Firmware updates.

    I can pick up the 2 pack of AX92U’s for $20 more than I can get two of the AX52U’s at the moment.

    Reply
    • Get the RT-AX92U, Mike. It’ll give you the option of using the 2nd 5GHz band for your client. That’s quite nice. And yes, make sure you upgrade to the latest firmware. Also, read this post.

    Reply
  26. Thanks for your advice, Dong, I appreciate you reading through my lengthy post!

    Something is *definitely* weird with those routers in my case.

    I have no switches or anything else in-between the router and my PC. The setup is equally simple: cable modem–>CAT 6 to WAN port on the RT router–>CAT 6 to Intel network port on an ASUS motherboard. I also had another wired connection to a Mac Mini. The rest was wireless, with the wireless backhaul.

    The LAN was phenomenally slow whenever a wired connection was involved, both on transferring files (wired to wired in the network, not internet, and wired to wireless!). The router reports 1GB connections on the wires, but they aren’t running anything like that. Oddly, it also reports a 100mb connection *on an empty port*. I assumed that was a firmware glitch, but maybe it’s more significant than that…

    Anyway, that the internet is also slower (FTP rates, etc.) is an annoying, but telling side effect. I’m not using it to measure network speeds, but when the wireless is universally faster (LAN, WAN, and Internet)–and I’m just waiting for simple pages to load, on *both* RT units, well, something is just not right there.

    By the way, it doesn’t seem to matter if QoS is on or off–it makes zero difference for the wired ports. So I hope the GT-AX11000 is (much) better and I can use one of the RTs as a mesh point!

  27. Hi Dong, been reading your reviews and i wanted to ask your opinion on using GT-AX11000 and 3 RT-AX92U. I have 2 boys who are heavy gamers. For me i need a good mesh and i have alot of IOT in my home, security cameras which need constant connection but they are all 2.4. I am also interested in ZenWiFi XT8. I would be using the GT as the main router, what should i use as my mesh? the RT-AX92U or XT8? I have ethernet which all lead to my main switch, i dont know if i can ethernet backhaul. Lets say for now i cant until i actually set it up and test it all out.

    • It’s better to use the GT-AX11000 as the main router and the XT8 as nodes, Joe, as you have already figured out. Wired backhaul is the way to go for sure, especially for gamers. Good luck! And have fun, too! 🙂

  28. Hi Dong, thanks so much for these reviews! They are truly insightful and important!

    I want to know what you think the best way to use the AX 92Us with an AX1100, and if the wired connections on the AX1100 are fast (I think I know, but the AX 92Us LAN ports seem so bad, I’m not sure any more! )..

    I bought the dual-pack of AX92Us before I read your review (alas!), and have them set up as an AI Mesh, with the wireless backhaul.

    After a lot of firmware upgrades, this has increased the coverage of my network, and has been pretty reliable, to tell the truth. As a result, the speed of some “spread out” devices has also increased (because of the mesh), and that’s good.

    As for wifi speeds, that’s good too, but not (as your article points out really well!) anything above regular wifi 5 speeds. That was fine too.

    But here’s my big problem. I connected my main gaming system / PC by wired connection to the router port, and it slowed down significantly (from my previous Linksys AC router)! How can the wired connection through a router be slow?!

    Even internet speeds are significantly slower through the wire, which is crazy: normal 5ghz wireless adapters are gettng consistently faster connection speeds both on the lan and from the internet!

    I”ve never seen this before, with the browser slowing to a crawl through the wired connection. I’m talking less than 30mb/s download on a Gigabit internet provider. When I switch out to the Linksys, everything is fine. I’ve tried both of the AX92U units: they are the same.

    I even replaced my wired LAN connection with an Intel-based wireless card (the ASUS AX 58BT) and got an immediate speed increase, though of course it’s NOT wifi 6 speeds.

    So I want to replace at least one of the units with the AX1100 as the main router, with a wired connection (or a wireless wifi 6 connection) to my main machine.

    For coverage, can I then run the 92u as a wireless mesh extension? Can I still have a Wifi 6 wireless channel or will that be dedicated to backhaul? Am I stuck trying to run cable through my three story place?

    Sorry for all the questions, but you’re evidently one of the few people on the planet who might have some real experience here (and excellent advice)!

    Reply
    • Running cables is always the way to go, Jamie. But if that’s not possible, you can use the AX1000 as the main router and the RT-AX92U as a node in an AiMesh setup. BTW, you shouldn’t use the Internet to test your network speed, it’s never accurate. More on that here. Also check your wiring and make sure that you don’t have a slower-than-Gigabit switch somewhere in between. Something is weird in your case.

  29. Hi Dong, Started reading your reviews recently, very fascinating reviews.

    I recently had one AX92U to test as single router, my main focus was to get NAS R/W speeds acceptable speed over wifi. (Via ethenet it easily do like 90MB/s, but I don’t have ethernet wiring in my home).

    So when connected with 5G-2, I see link speed of 1.2Gbps with the computer (Keeping them same room), but when copying files it never reach more than 25MB/s (~250Mbps). Is that max with this router? What you recommend if i’m looking for better NAS speeds and what max speed I can achive?

    Also I have general confusing about AiMesh, say I have AX11000 and AX92U if I enabled AiMesh wirelessley. still it gonna be Wifi 6 wireless mesh?

    Reply
    • The top speeds of this router are the numbers on the charts above, Praneeth. But connecting at 1.2 Gbps means it’s already at half of its max speed. I’d check the settings and make sure it uses the 160 MHz channel width. Generally, for max NAS speed, you need a wired connection. Wi-Fi always fluctuates a great deal. As for AiMesh with the RT-AX92U I talked about that quite clearly in the read, so read it again. But in a wireless setup, the RT-AX92U is as good as a Wi-Fi 5 mesh system.

  30. Just wanted to say thanks for the reviews! These were fantastic and not just ads. I read like 5 hours of reviews last week here and made the purchase on ASUS RT-AX92u (smaller cape cod house), after configuring it my bufferbloat is gone, ping spikes are gone and packet loss is gone (moved on from AX50 from tplink which was horrid)

  31. Dong, I’m wondering if you can confirm something I’ve found with this unit. I have the RT-AX92U connected to my AX11000 via ethernet. I followed the recommended instructions of connecting it via WiFi first, then I moved it to its new home where it’s connected via ethernet to the AX11000.

    When I perform a wireless network scan, it shows both 2.4 networks at 20 mHz, both 5G-2 networks at 80 mHz (I assume they’re at 160 but the mac is too old to recognize that), however it shows the AX11000 producing the 5G-1 network at 80 but the AX92U at 20. I for the life of me cannot figure out why that is. Do you see the same results on your units? Or am I missing something and should I re-set the AX92U?

  33. I have a GT-AX11000 and an older RT-AC68U in an AiMesh, the GT being the primary node. I have been having intermittent issues with seeing clients from either side (ie workstation on primary, NAS on secondary, etc). And just losing connectivity altogether on the RT. So it is time to replace the RT. I was looking seriously at the RT-AX92U until I saw this write up. So, thank you for that. The issue I take is no WiFi6 without a wired back-haul. Which model, in your experience and opinion, would be best to pair with the GT so I can get WiFi6 wirelessly without a wired back-haul?

Looking to add the AX-92U as like the common UI, features etc. However, just so I am clear, I would be looking to run wired back haul via ethernet powerline adapters. Can I then use Wi-Fi 6 through the mesh? Also presume I will maintain all of the existing 2.4ghz and x2 5ghz channels?

    • You shouldn’t use powerline with Wi-Fi 6, Nish. It’s too slow — don’t count on the number vendor claims. Run network cables. And yes, the 5GHz-2 band will be Wi-Fi 6 throughout the mesh. More on that here.

  35. Thank you. It’s really helpful. By far the best review I’ve ever read. Informative and easy to understand even for someone like me who doesn’t know much about network.

    This review helps me learn a lot. Unfortunately I found this review a bit too late. I purchased a pair of RT-AX92U and use as the the AiMesh.

    I need some question that I can’t find the answer,

    My setup right now is
    Main router – RT-AX92U
    6 AiMesh node – AX56U (5 units) + RT-AX92U (1 unit). All connected via ethernet (wired)

    If my phone (wifi6 supported) connect to AX56U (node) will I get the wifi6? or it is just wifi5.

    Would you recommend replacing the RT-AX92U with RT-AX88U or GT-AX11000 and use RT-AX92U as a node?

    Thank you.

    • This depends on how you set up the system, Wittawat. If you just use the default setting, the RT-AX92U is just a 2×2 Wi-Fi 5 router. More on that here — check out the tri-band part. Considering you have wired backhaul, you’re fine as it is. 🙂

  36. Would two of these give me the best total horizontal coverage for the money if I used a wired backlink to connect them? I have a 1400 square foot ranch home and need better coverage for WIFI calling (including covering the area just outside of the house). I already have ethernet cable installed from one end of the house to the other, is this more effective range wise than a single AX11000? Link aggregation for a total of 2Gbps if enough for my home server needs and I have gigabit internet.

  37. Dear Dong,
    Thank you. Another thing what if I wanted to add another Asus router like the AX11000 to my mesh network which comprise of Ax56u would that be possible since the Ax56u only support channel 20,40,80 and the Ax11000 can support 160. Would I be able to force the router to work only specific channel like only 160mhz?

  38. Is there any chance of Asus opening the 5Ghz-1 to 4×4 160 Mhz like they plan to do for the Zenwifi XT8 with a firmware update? I have just bought the ax92u but I can still return it and swap for a XT8. I’ve got gigabit internet so I’d like to try and maximize the 80211ac devices.

    • There’s a chance and they are still working on it last time I checked, Garrett. However, considering the world is in lockdown, nobody knows how long that will take.

  39. Great article, thank you. I am just exploring a Wi-Fi 6 mesh system for a 3x story house and basement (roughly 3000 sf) with wired Ethernet on each floor. The Asus RT-AX92U 2-Pack may work for the entire house; however, if I need to add a third is it possible with a wired backhaul either a serial or star topology? If not can the third RT-AX92U be added wirelessly?

    Or would you recommend another system for our house like the TP-Link X60, Netgear Orbi, or other? Having the extra Ethernet port(s) at each device is helpful and the Asus and TP-Link pricing are attractive. The Netgear Orbi seems the most flexible wired backhaul and extra Ethernet ports; however, the pricing is much higher. Thank you.

    • If you use wired backhaul, it doesn’t matter what topology you use, David. But you don’t need tri-band broadcasters. You can go with the TP-Link Deco X60, or a couple of units of the Asus RT-AC86U and/or RT-AX3000, and/or RT-AX88U, if you want Wi-Fi 6 with a ton of ports.)

      If you use mostly dual-band routers with wired backhaul and want to add another wirelessly, you should still consider a dual-band router. That’s because the last one’s 3rd band doesn’t do anything in this case unless your main router is also a tri-band.

  40. Hi Dong,
    I am looking to upgrade as my house WiFi coverage and speed wise all are not great. I am looking at Asus 92u twin and Asus ax56u twin all set in mesh mode. Which one would be better?

    Reply
  41. Great read, I have read and watched a lot of reviews for this and no one besides you has clarified that the mesh network will not be WiFi 6 without a wired backhaul.

    Personally, I’m considering this product because I want more consistent coverage in the upstairs office of my home. My main router has to be downstairs, so my hope would be to take advantage of the strong wireless backhaul between the two routers, and then connect all of my important devices upstairs via ethernet cable to the secondary router. My best possible internet speed from my provider is 1 Gb, so I don’t need true Wifi6 speeds anyways. My main priority would be stability and low latency for gaming (I’d be gaming in the upstairs office). Do you think this would be a good solution, or should I look elsewhere?

    • Glad you’re here, Michael.

      First of all, if you’re REALLY serious about gaming — and I speak from experience — you need to think about running networking cables. The rule of thumb about gaming is either you connect the console (or computer) directly to the router via a network cable (best) or wirelessly (OK). Directly is the key here. That said, this 92U will work for you if you intend to connect your console with a wire to the node. If you’re thinking of connecting your device to the node wirelessly, no system will work well for gaming due to latency. If it does, that’s only temporarily, or you have certain types of games that don’t require low lag.

      Considering you have 1Gbps Internet though, wiring is the best option. Period.

      • Been reading your stuff for hours. Many thanks for the work you put into this. Similar to this line of thought (although I do not play multiplayer so I care more for higher bandwidth to download games quick than latency), with a gigabit internet connection, would I be better off with a single mega fast router like the AX11000 and connecting to that router using a wifi card like the pce-ac88 which is a AC3100 wifi client or would I be better off with either a pair of XT8s or AX92Us in mesh using wireless backhaul with the PC wired by ethernet to the node? My personal feeling is wired to a XT8 or AX92U node which is connected wirelessly to the corresponding pair set as main router would be better for bandwidth as the router itself with wireless backhaul might be a stronger connection bandwidth wise than the wifi card but would be good to get some clarification.

        • Single router vs. a mesh system is the question of Wi-Fi coverage, Vik. For gaming, it’s best to use network cable(s). In your case, assuming the distance is not an issue, either way will make no difference in terms of performance.

          Reply
    • Either will work, but that’s a tough combo for wireless set up. If you use wired backhaul, it doesn’t matter which you use as the main router. Otherwise, try the latter as the main router first.

  42. Thanks for your reviews. Purchased a GT-AX11000 based on your reviews and love it, but what’s the best ASUS AI Mesh router or extender to add to my network using wireless back haul? I was going with an RT-AX92U until I read the issues you noted with the wireless back haul. I see you’re using the RT-AX92U with wired, but wired isn’t an option for me. I don’t want to shell out $400 for another AX11000 as a node as that’s overkill for me. If I’m understanding correctly there’s nothing gained by using an RT-AX92U due to the wireless back haul over something like the RP-AC1900 mesh node. And the RP-AC1900 is half the price. Do you have a recommendation for WIFI 6 AI Mesh node under $275 for use with the AX11000? (More than that amount, and I’d just think another AX11000). Thanks so much for the work you do!

    Reply
    • Sure, Todd. Glad you’re here. Tough call. For your case, considering the budget, I think you should go with a single RT-AX92U. It will work fine and it’s better than a Wi-Fi 5 router since it’s a tri-band.

      • Hello Again. Per your recommendation I did purchase the RT-AX92U as my mesh node to go with the GT-AX11000. It has work great and nearly flawless for 6 months. So thank you for the input. Unfortunately, the last few weeks I have several devices that will lose WIFI connection simultaneously. The ASUS network map seems to show that the devices are still connected, but the devices themselves show disconnected status and unable to obtain IP address. They are unable to reconnect until I restart the router and/or node. Rebooting either the router or the node temporarily corrects the issue (for a time ranging from minutes to a day at best). I have hard reset both routers (router and node), and returned to defaults, but the issues remain. Firmware is updated to latest on both. I can establish no pattern. Signal is strong, no changes etc. I’ve contacted ASUS to no reply. I realize this is perhaps a long shot given the limited information I’m providing, but might you be familiar with this type of an issue that suddenly began with a system that was working excellently for months prior? Might this be a hardware failure? What things could I check or change from the default settings? Thank you so much for your time and the work that you do!

        • That’s very odd, Todd. Try swapping the roles of the two routers to see if that makes a difference. My take is if something happened hardware-wise, that should only happen in one unit.

          Reply
          • Thank you for the suggestion to swap devices. Currently I’ve taken the RT-AX92U out of my network as the mesh node, to run the AX11000 as a stand-alone router. So far, no issues despite weaker signals to some devices. I plan to run this way longer to confirm the device drops don’t return. After that, I will test the router swap you recommended. However, based on this early result, I’m leaning towards a mesh issue and/or issue with the AX92U itself, but I’m certainly no expert. The GT-AX11000 / RT-AX92U combo worked great for 6 months, so hoping to get back to that state. Thank you again!

          • Todd, if you do wind up adding the AX92U back in and see more “weird” drop-outs, you should check the Asus section of the SmallNetBuilder forums. They’re pretty active, and I think I’ve seen some threads discussing this kind of problem there. (I haven’t dug too deeply, as I’ve been lucky enough to avoid this specific issue, thus far…)

  43. It’s interesting. Now I have gtax11000 as router and ac88u as node. Imac connects to node with 1300Mbs speed and 450-600Mbs internet speed (ac88u is dual band ac only router)

    Reply
  44. I have never reached 1G wiffi connection with neither router or a node in this kit. The best was 800M with internet speed of 300M on iMac. The whole 5M-2 is busy with backhaul

    Reply
  45. I assume this will be adequate to get gigabit Internet into my bedroom on wired devices? I don’t have any WiFi 6 devices so if this does the trick it will be a cheaper option than the XT8. I’m going to be using the wireless backhaul and have a pretty small apartment (with brick walls).

    Reply
  46. Hi,
    I tried it (twice). The first kit was unstable + router part had low connection transfer (forget about connecting ac88u to them). So I replaced it to another kit which kept disconnecting from internet hanging the router (hard reset was necessary). Now I enjoy GT-ax11000 and everything is like a music. I am not sure what’s wrong with ax92u ?hardware ?firmware, but it is so unreliable and waste of $$

    Reply
    • I agreed. It’s prolly one of the worst Asus routers. The issue is the 5GHz-2 band which is only good when working as a backhaul.

      Reply
  47. Thanks Dong for the promo reply. Regarding set up, I restored the XT8 with the AX92 Settings and it lost the original Mesh node and I had to add it manually. I was able to add one AX92 Mesh node and it used the wifi6 backhaul channel. The CT8, in contrast, would connect its WiFi 5 to which channel of the XT8? I think the AX92 is more flexible, especially that when using a wired backhaul channel, one would get a WiFi 6 channel if it happens that one has a compatible client.

    Reply
  48. I have both a pair of the rt-AX92u as well as a pair of ZenWiFi XT8, obviously, since I have only wifi5 clients, they are both equally fast!
    My question is, why would you recommend the ZenWiFi CT8 over the AX92u as a wifi5 AiMesh, considering that the ax92u has the faster Backhaul channel?

    Reply
    • When you have both up and running, they are kinda the same. But the CT8 is much easier to set up. It also has better AiMesh implementation. If you try using the AX92U as a single router, or if you open the backhaul band to clients when using it as a mesh, you’ll note that its Wi-Fi 6 band doesn’t support mobile Wi-Fi 5 devices very well.

      Reply
    • It does but I don’t think yo should do that, Chris. For one, it’s too expensive. And secondly, it seems the Wi-Fi 6 band is not tuned to be compatible, so you might get very slow speed if you connect it to a Wi-Fi 5 signal.
