ZenWiFi XD6 review (vs ZenWiFi XT8): An Excellent (Wired) Mesh Alternative

If you read my review of the ZenWiFi XT8, you’d note that I recommended it mainly for those living in a home with no network cables. If you have gotten your home wired, though, this Asus ZenWiFi XD6 AX5400 is an equally excellent alternative.

Sure, it’ll work in a wireless setup — and did quite well in my testing, as you’ll see below — but it’ll work best in a wired configuration. In fact, in this case, it’s a sizable upgrade to entry-level ZenWiFi XD4 thanks to the extra amount of ports and full support for Asus’s core feature set as well as AiMesh 2.0.

Since I have reviewed both the XT8 and the XD4, this brief review is more of a ZenWiFi XD6 vs XT8 matchup where I’ll highlight the differences between these two.

The bottom line is: at the current cost of around $380 for a two-pack, the ZenWiFi XD6 is an excellent mesh system, especially for a wired home with a Gigabit-class or lower broadband connection. Get it!

ZenWiFi XD6 (vs XT8): A smaller yet equally robust mesh solution

You can’t look at the ZenWiFi XD6 without think of the XT8 — that is if you have seen the latter. The two look the same despite the fact the XD6 is just about two-third of the physical size.

The XD6 also comes in a 2-pack of two identical routers. On the back, it has the same amount of ports as the XT8 but now without a USB port. Also, its WAN port is not a Multi-Gig — this is a pure Gigabit Wi-Fi 6 router.

ZenWiFi XD6 (vs XT8): Hardware specifications

On the inside, the XD6 and XT8 share almost the same processing power — the latest has a slightly faster CPU– but their differences in Wi-Fi specs are more significant.

Specifically, the XD6 is a dual-band router while the XT8 is a tri-band. So take the 2nd 5GHz band (5GHz-2) band out of the latter, and you kind of get the former, so to speak.

However, the lack of an additional band is not exactly a bad thing, as I talked about that in detail in this post on Dual-band vs Tri-band.

In this particular case, the XD6’s only 5GHz band is a top-tier 4×4 that supports the 160MHz channel width. On the other hand, while the XT8 has two 5GHz bands, by default, its front-haul band is of modest 2×2 specs.

Hardware specifications: ZenWiFi XD6 vs XT8

Pre-synced hardware, family Asus core feature set

Out of the box, the two XD6 units are pre-synced. As a result, you just set up either as the main router. After that, plug the other one into power at a good distance, and you’ll note the AiMesh system is ready.

But even if yours didn’t work out that way, you could always add the 2nd unit or more Asus AiMesh broadcasters to the mix via the normal process, as I detailed in this post on AiMesh.

ZenWiFi XD6 Mesh
Here’s the 2-pack ZenWiFi XD6 in an AiMesh setup. The 2nd unit is part of the mesh as soon as you plug it in.

As a rule, though, if you want a wireless setup, pick a broadcaster of the same 5GHz tier. But it’s best to use other dual-band routers with wired backhaul.

On top of that, the XD6, as a standalone route or a mesh, has the full support for Asus’s core feature set, as well as AiMesh 2.0.

Consequently, you can expect to get the same Wi-Fi settings, features, and tools as most other Asus Wi-Fi 6 routers. And in a mesh setup, the Guest networks (one for each band) will work throughout the mesh.

For the first-time readers: Asus’s standard feature set

The XD6 has no USB port, so it has no USB-related features. Other than that, it has everything you’ll find in most Asus routers, including:

Universal setting restoration

You can restore the backup settings of most of the Asus Wi-Fi 5 and Wi-Fi 6 onto the XD6, including those with an AiMesh setup.

I tried that of the few previous dual-band routers — RT-AX86U, GS-AX5400, RT-AX82U, and so on — and they all worked.

(Note: You can’t do that if you use the backup files of the RT-AX89X or the Blue Cave.)

That said, if you want to upgrade from an existing Asus router, the XD4 will make it an easy job.

A robust web user interface

Asus is one of a few networking vendors that stays true to the web interface and doesn’t coerce users into a cloud-based web portal, which is excellent for those caring about privacy.

(All Asus routers allow remote management, which is turned off by default, via Dynamic DNS.)

The interface allows access to a router’s tons of settings and features. Savvy networking enthusiasts will love that though it can be a bit overwhelming for novice users.

ZenWiFi XD6 Wi Fi Settings
Like most Asus routers, the ZenWiFi XD6 has a ton of Wi-Fi customization.

Standard setup process

Thanks to the web interface, all Asus router has the standard setup process, as I detailed in this post on building a home network from scratch.

If you have worked with an Asus router before, you’ll feel right at home when it comes to setting up the XD6.

Here are the general steps:

  1. Connect your router’s WAN port to the Internet source, be it a modem, an existing gateway, or the Fiberoptic ONT. Turn it on.
  2. Connect a computer to the router, either via a network cable to one of its LAN ports, or the default open Wi-Fi network, generally named “Asus xx”.
  3. Open a browser and navigate to the router’s default IP address which is 192.168.50.1 (or router.asus.com).

The rest is self-explanatory. The first time you get to the web interface, you’ll run into a wizard that walks you through a few steps.

Again, if you get a 2-pack, the XD6’s hardware is pre-synced. Once you’ve set up the router unit, you’ll find the other is already part of the mesh when you plug it in.

(Alternatively, you can also use the Asus mobile app in step #3 if you use a phone or tablet instead of a computer. However, I recommend the web user interface even when you use a mobile device for the setup process.)

Helpful mobile app and doesn’t require a login accout

Again, the Asus mobile app works for both the setup process and ongoing management.

This app is common for all Asus routers and is quite comprehensive. It’s one of the best mobile apps for routers you can find on the market. But, still, it’s not as in-depth as the web interface.

The best thing about it is that you can use it to manage the router remotely without a login account. Instead, just like the web interface, it operates the remote management via the router’s built-in support for Dynamic DNS feature that includes a free SSL certificate.

However, one thing to note is that using the app can inadvertently turn on or off specific settings that could cause the router to behave unexpectedly. In this case, you’ll have to reset the router and set it up from the beginning.

The point is is this, while this app is convenient and fun to use, it can be dangerous for those who like messing around too much.

AiProtection

The AiProtection is one of a feature that adds so much value to an Asus router. It includes a free-for-life real-time Network Protection powered by Trend Micro and a Parental Control engine.

ZenWiFi XD6 AiProtection
The ZenWiFi XD6 has the helpful AiProtection feature.

Unlike the XD4, which has entered AiProtection, the XD6 shares the same level of this feature as the XT8 or any other high-end Asus router.

The Network Protection is to keep the entire local network safe. In many ways, it’s like a strip-down version of a premium add-on firewall, such as the Firewalla or the subscription-based Armor from Netgear.

Like the case of all Asus routers, the Parental Control portion is a bit too simplistic, rigid, and lacking. The way Asus defines categories for web-filtering is vague. On top of that, you can’t use it to block a particular website.

Adaptive QoS

The Adaptive QoS is a common feature available in all Asus routers and is one of the most easy-to-use QoS features among all home routers.

Read this  QoS Explained and How to Get Better Voice and Video Calls over Wi-Fi
ZenWiFi XD6 Qos
The interface of ZenWiFi XD6’s QoS feature.

“QoS” stands for the quality of service, and it enables users to prioritize Internet traffic to support different applications or services.

Other useful features

Other than the above, you can also expect the following from all Asus routers:

  • Networking tools: Wake on LAN, Ping, Netstat, and Smart Connect Rule can come in handy for advanced users.
  • Traffic Analyzer: A set of tools and statistics in case you want to find out what’s been going on in the network in a set amount of time, and in real-time.
  • The usual set of network settings and features: These include Dynamic DNS, IP reservation, Port-forwarding, VPN server, and some Alexa Skills.
  • Frequent firmware update: Asus pushes out firmware updates on a regular basis to, for the most part, fix issues and improve its routers’ performance and function.
ZenWiFi XD6 Tools
Wake on LAN is an excellent tool in case you need to remotely turn on a network device.

By the way, I tested the XD6 with the latest firmware. Its initial firmware was a bit buggy, which is why I waited until now to publish the review. The mesh was first released earlier this year.

ZenWiFi XD6: Excellent performance

I tested the XD6 as a single router and as a 2-pack wireless mesh system, and it did very well in terms of sustained throughput speeds, as you can see in the performance charts.

The wireless mesh also passed my week-long stress test with no issue at all. I used it as our primary home system, and everyone was happy during the trial.

ZenWiFi XD6 Router Performance
Note: Different Wi-Fi 5 clients in use: 4×4 in close-range tests and 3×3 in long-range tests.

Again, the system works best when you use a network cable to link the hardware. In this case, you can expect the performance of the satellite unit to be the same as that of the router unit. But even in a wireless setup, the XD6 satellite did well, even against some tri-band counterparts.

ZenWiFi XD6 Satellite Performance

Despite the smaller footprint, the XD6 had an excellent range in my testing, about the same as the XT8.

Wi-Fi coverage is always tricky to figure out precisely since it depends on the environment, but you can count 2-pack XD6 to cover some 4000 ft² (372 m²) when placed strategically.

Conclusion

The ZenWiFi XD6 is an excellent dual-band mesh system. It’ll work well in a wireless setup if you don’t need to get the best performance out of it. And if you have gotten your home wired — as you should — it’ll be even better.

Read this  How to Get your Home Wired with Network Cables (Almost) Like a Pro

In this case, the fact each hardware unit has multiple network ports means when you need more than two units, you can daisy chain them, which saves you from having to get a switch, like the case of the XD4. And it’s always nice to be able to plug a few wired devices into your network immediately.

The lack of a USB port and the support for Multi-Gig sure is a bit of a downer. But if Gigabit is all you need, which is the case for most of us, this is an excellent buy. Get it!

  1. Thanks for the review. Currently I use two of the Google On Hub routers, with wired house, one as the main and another as a bridge with the same SSID. Upstairs I have weak signal strength.

    Can I use two pairs of the XD6, for a total of four, with one of them as the main and the remaining three connected by ethernet? Do I gain anything if I went with the XT8 if I have newer laptops and mobile devices?

    Reply
      • Thank you. Your quick feedback makes your website a valuable resource. So with the XD6, if I have 1 main and 3 satellites, the satellites would be configured in bridge mode or wired mesh mode using the ASUS software application?

  2. Hi Dong,
    Thanks for your extremely useful site.
    I know you said go for the XD6 over XT8 for wired backhaul scenarios. However, I’m keen to understand a little more – if the XT8 and XD6 are the same price, then would the XD6 provide better performance in this scenario, even if all 3 bands of the XT8 were in use for wifi devices? It seemed to me that the 5Ghz-2 band of the XT8 is equivalent performance of the 5Ghz of XD6, the 2.4Ghz should perform equally, so the 5Ghz-1 of the XT8 in a “bonus”.
    Appreciate you’ve flagged previously potential instability of XT8 in new firmwares since they are optimised for wireless backhaul set ups – wonder if this is a factor in you comparing XD6 vs XT8 performance?

  3. Hey Dong,
    Thank you for this review. Because of you, I bought this specifically for my newly wired home and it’s working great.

    Question about one of the AIMesh settings: Would you recommend turning on the “Enable Ethernet Backhaul” setting, or should I just leave it alone?

    Reply
  4. Hi Dong – after reading your review and doing my own research I bought an XD6 twin pack for use as an AiMesh AP and it’s proven as good as I’d hoped in the role. I’ve got two wired networks in my house, one for our computers and associated equipment, the other for IoT devices. My current router allows me to bind ethernet ports to individual interface groups as well as WiFi networks, so I can assign the guest WiFi to the IoT group and keep all guest and IoT clients isolated from those on my private home network. You currently can’t do this on the XD6, which is a little surprising given the potential security issues with IoT devices on your private network. Hopefully Asus will address this going forward but until then, I’m perfectly happy with the XD6 in its AP mode. Thanks for helping me make my decision.

    Reply
      • Thanks Dong – I’ve always used Billion routers and hadn’t realised port-based VLANs wasn’t a common capability ☹️, so I can’t assume such will likely be on the XD6’s development roadmap. As I’ve got a number of wired-only IoT devices, it looks like the XD6s will remain in AP mode!

  5. Dong, I’ve got a Deco M5 3-unit system in use for the last year that just isn’t living up to its hype. Using NetSpot, I’ve been able to determine my problem is generally poor signal strength in my house and my neighbors’ networks frequently have stronger strength in my house than my own network. So I am looking for something that is likely better and this XD6 seems to be perfect. However I was hoping for a 3-unit system that costs less than $400 and this is only a 2-unit system with no single unit options to add on. Any thoughts on whether the XD6 would likely have better signal strength than the Deco M5 and what I could use as a 3rd unit to an XD6 2-unit system?

    Reply
      • Oh yes, my current Deco M5 setup is all wired. The house is pretty much fully wired with jacks in most rooms so the limitation on where to put a unit is pretty much limited only by aesthetics. I’ve got the Comcast modem in the basement (in bridge mode) hooked up to a Netgear R8000 running dd-wrt (WiFi off) and that’s connected to the main Deco M5. I’ve got three unmanaged switches connected to wires throughout the house including to the other two M5 units. I’ve got an M5 in a closet in the attic; and the third M5 is on the 1st floor in the family room – I’d rather have it in an electronics closet but the signal was too poor there. There are no units on the 2nd floor since the attic one gives good coverage downward to the 2nd floor rooms (or at least it should). So ideally I’d like to replace the 3 units with 3 better ones and that’s why I’m disappointed a 3-unit set isn’t an option with the XD6. Although I did now find that Amazon will sell a single XD6 for $200. So that’d be $550 for a set of 2 + 1 additional. Ouch. But the options in your AiMesh combo post are all in a similar price neighborhood so I wouldn’t save much by finding the cheapest addition – not without sacrificing some of the reason to upgrade to the XD6 in the first place. But that results in each XD6 costing more than all three of the Deco M5s. Maybe I’m better off just buying 2 or 3 more Deco M5s!

        Reply
        • I was in the same boat with the 2 + 1 XD6 decision. My house is wired in all the rooms including the garage and hallways. So i ended up using five XD4s as satelites with an RT-AX68U as a router, instead of 3 XD6s. I have zero dead spots now.

  6. Hi Dong,

    I just found this site and it’s been really helpful to me in selecting a mesh router.

    I’ve been using an Orbi 5 for the last 4 years with some compromises; hardwired Nvidia Shield and wired backhaul when I moved my office downstairs(wireless backhaul was spotty).

    I’m moving the Orbi 5 to my in-laws place, and initially went with the Orbi 752. This site helped me realize that I didn’t need it. I’m returning it and getting the XD6.

    Thanks for all your hard work.

    Reply
  7. At this time XD6 and XT8 are almost the same price. While working with wired backhaul in a house with a lot on concrete, would you go for XD6 or XT8, also taking into account some point might end up in a closet (XD6 is slimmer and maybe has less heat?)

    Reply
      • Hey Dong,

        I do have my house wired and have just picked up the XD6, but will be moving to a larger house and will need one more node. Do you recommend the RT- AX88U to go with this alongside of the XD6 in an Aimesh set up?

        Reply
          • After reading this article and this amazing one “ AiMesh in 2021: Asus’s Ongoing Effort to Excellent Wi-Fi Coverage”, by Dong, considering I live near an airport (no need for 160 mHz) I ended up with the XD4 kit and an AX68U via a WIRED backhaul. Wish me luck. Dong have you tried running Merlin on any of the Asus routers, if so any pros and cons? Thanks again for your wonderful site. Without it I would have wasted money on getting an incorrect combo.

          • I was hoping to avoid the use of a switch, hence the 88u but is there something specific about the 86U which I am missing in this recommendation?

  8. Help me decide on my WIRED backhaul setup. I’m torn between getting the xd6 and the xd4. In terms of the 160 mhz, I also live 2 miles from a small airport in Hayward, CA. i have a bout 4k of living space, 4 bedrooms. I plan to use more than necessary to overlap the dead spots. The plan is to have 3 units of the xd6 vs getting the xd4 in every room. for the same price of the getting 3 units of the xd6 , i can get 2 sets of the xd4 (six total). On the xd4 can the other main be set as an AP or (satellite of the other main)

    Reply
    • With wired backhauls you can go with either Duane, or a mix of the two (the XD6 as the primary router), but you’ll need a switch if you go with just the XD4. And yes, if you live near an airport, don’t use the 160MHz, just 80MHz, and it’ll work fine.

  9. Hi Dong,

    I am using XT8 now.

    But, smartphone connect to 5ghz-1 unable to get full speed. Only connect to 5ghz-2 can get full speed.

    Why?

    If connect 5ghz-2 will affected overall mesh performance right?

    Reply
    • I don’t know how you set it up, nor do I know what you mean by “full” speed, Kenny — more on testing in this post. But in a fully wireless configuration, the 5GHz-2 is not supposed to be available to clients. Check out the review of the XT8 or my post on AiMesh for more.

  10. Hi dong,

    In your specs you state the XD6 has no link aggregation, but on the website of Asus it states that it does.

    I trust you more… but who is really correct?

    Reply
  11. Thanks for this comparison Dong. It’s very useful.

    If you don’t mind I have a question as I’m struggling between XD6 and XT8. I saw XD6 pack on deal and was thinking of replacing my current RT-AC86U router (or adding more) as I have issues with the 5ghz band when I add more devices. I currently have 25 devices connected in total of which 7 are on lan, ~3 on 2.4ghz and the rest 15 on 5ghz. When I have family over and 4-5 devices get added on top the router struggles to assign an IP. I also have a PS5 which is constantly struggling to get an IP and even when I set a static it still struggles to connect for some reason.

    I was thinking that splitting the devices between 2 routers might help alleviate the load on the current one. I live in a 1500sqft house with 1gb fiber, the router on the ground floor and no signal issues (can reach 300mbps on the top floor). Do you think it’s worth getting the XD6 or even paying extra for the XT8?

    Reply
  12. Hey Dong!

    We have a wired home but I am struggling with a decision on a new system without having buyers remorse. Our current setup is the Orbi RBK53 and I am looking for better wifi range/coverage and would prefer something smaller and less obtrusive. Our home is a 2200 sq/ft ranch with finished basement and about 1100 sq/ft garage. Roughly 40 or so connected devices with Ring cameras at each corner.

    We have gig fiber service so I would like strong wifi coverage to take full advantage. I prefer something with Wifi 6 but do not necessarily need 6E, tons of features, or robust parental controls. Cost is always a consideration, but not a limiting factor.

    Any thoughts?

  13. Hi Dong – came across your site yesterday when researching mesh WiFi for the first time and it’s excellent – understandable and thorough. I noted some of your comments regarding privacy – I do NOT want to connect my LAN to any cloud-based systems (at least not knowingly!) – do any of the mesh systems allow you to turn off this feature? I’m looking particularly at dual band wired backhaul systems. I expect to only be able to use such a system in AP mode of course. Many thanks, Mike

    • Happy to have you, Michael.

      This one is great, or you can find more options in this post on the AiMesh combos.

      Note, though, that generally, Asus routers are good on privacy, but if you turn on certain features, like AiProtection, well, you will have your traffic looked at by a third party. That’s like you can’t have a bodyguard without… a bodyguard. You probably can get a Linksys or Netgear, too, but in that case, you might want to check out these tricks to be safe from privacy risks.

      Reply
      • Thanks Dong – I’ll check your suggestions out. Your comments about network privacy are spot on and I can’t really believe people are prepared to have their network traffic monitored by a third party in the name of ‘increased security’ – it sounds like a contradiction in terms! Maybe though it’s just me and I need to get my paranoia treated…..

        • Hello Dong,

          Sorry to bother again but I’ve been struggling with a router decision. I’m living in a 1065 sq ft 3-room flat (single floor) where a single broadcaster Asus RT-AC86u is placed at one side of the flat. I don’t have any major issues with Wifi connections for my 1Gbps broadband plan for both 2.4ghz and 5ghz. But I wouldn’t mind increasing the peformance of my wifi. I mainly have about 20+ Wifi 5 and Wifi 4 clients (smart home). No Wifi 6 clients at the moment. My use cases are mainly around working from home, web browsing, video streaming and I do not game. I have a CAT6e wired LAN connection from my router (living room) to my study.

          I have a chance to buy either of these 2 routers at a promotional price when I renew my broadband contract – Asus AX88U (at ~USD230) or Asus ZenWifi XD6 2-pack (at ~USD195).

          I would have wanted to get the AX86U but that’s not available. I’m worried that my house is too small to have the XD6 2-node mesh work effectively – I read from your great article that more doesn’t always mean better for mesh. =) Having said that, I would put the satellite in my study to have wired backhaul.

          Given my situation and the prices of the 2 routers, which would you choose? Many thanks again for your keen insights.

          • I’d go with the 88u, Ian. Considering your clients, I think things will remain the same tho.

  15. Hi Dong,

    I noticed at the end of your review that you stated that guest networks will work throughout the mesh. I assume this means that all 3 networks for both bands are available on both the main and extended nodes? I found the post below about how only the first guest network is available on both the main and extended nodes and the second and third networks are only available on the main node for the XT8 system. Can you confirm this is not a limitation with the XD6 system? I intend to use some of these guest networks as isolation networks for IoT devices and want to make sure they are available throughout the mesh not just on the main node.

    Thanks

  16. Hi Dong,

    Amazing page you have here. You’re so thorough and you make this stuff understandable to a novice.

    I want to upgrade my router to a mesh system. I have Cat6 wired in most places and plan to purchase the Asus Zen XD6 per your recommendations and rationale. My question is, I can get the XT8 for nearly the same price. I have a NAS that hosts my plex media server. I don’t have fiber internet and my top speed from my service provider is 200mbs. I don’t think I will ever have fiber internet. My NAS is capable of 2.5 GBE (2 ports). Should I consider the XT8 over the XD6 given the similar pricing and the 2.5Ge or do I really need a mesh router with link aggregation to improve my NAS since my ISP speed is 1g?

    Thanks!!!

  17. Hello Dong, thanks again for the hard work reviewing these routers. I have been thinking about upgrading my old router to a new mesh system to get more coverage in the house + backyard. Since my house has wired ethernet (Cat 5e) I was considering the TP Link deco x5700 (with wired back haul) since this tops the performance charts, and beats the XD6 in performance. The TP Link x5700 is on sale at Costco for $299, $80 cheaper than the new XD6. Do you think the new XD6 is worth the $80 more in my case?

    • Yes when you consider the privacy and other features, Mike. You only need so much in throughputs which The XD6 will be the same in a wired backhaul setup. But it’s your call.

  18. Hi Dong. I am really considering the XD6 system for my home. I have(will have) wired capability and 3 floors to cover in a larger home. So I am thinking a node on each floor for coverage. To explain a little more, my in-laws live in the basement. My question is should/can I buy an additional node for the 3rd floor? Or are there any other recommendations/setups for the Ai mesh? I really would like to have some signal out in the backyard as well, so great wifi signal strength is a must. I do have 1G service from AT&T.

    • I’d start with a 2-pack and see how that goes, Jamie. You can always scale up with more dual-band at a latter time. Check out my posts on AiMesh for more.

  19. Which would you recommend for a setup with 2 wired routers, – 2x XD6
    – 2x RT-AX82U
    – 2x RT-AX68U

      • Indeed Wi-Fi coverage would be most important for me. Any reason why the XD6 would be better for this? I would have expected the AX82U to be preferred though with its 4 large antennae.

        I couldn’t find a direct comparison of their mesh performance, but saw in one of your posts that the AX88U performed a bit better than the XT8 as a satellite… So I expected the AX82U would similarly be preferable to the XD6.

        • Yes, Matt. Chances are, the RT-AX82U is slightly better in terms of coverage in a wireless mesh setup. However, if you have wired your place, the difference is very minimum, if at all.

  20. While the XD6 is a nice addition to the Asus product line, the real “missing link” would be an upgrade to the XT8 that makes all of the LAN ports 2.5 gb instead of just the WAN port. Assuming you have a wired mesh interconnect, if they did that, then all of the XT8 nodes that are operating as mesh extensions could use their WAN port to connect to the base router XT8-replacement at 2.5 gb, and you could also connect a relatively reasonably priced 2.5 gb LAN switch to one of the ports and start upgrading wired ethernet nodes to 2.5 gb as well. This would be a significant and reasonably priced upgrade path to a 2.5 gb home network given the leap to full 10 gb is still somewhat pricey. Also, given that many ISPs are now offering Internet backhauls at speed above 1 gbps (Comcasts 1gb offering is really provisioned at about 1.4 gbps at the cable modem and will probably inch higher in the future) you would enable user nodes to really take advantage of greater than gb speeds. If anyone at Asus is reading this stream (I assume some of them are), then try and get that product to market asap!

  21. Hi Dong.

    TokyoJerry here again. Regard your last point on matchups, I checked your listings to see if I had something similar to mine, but didn’t find any.

    Current setup:
    RT-AX86U (Dual-band)
    RT-AX92U (Tri-band)

    I use these with AX92 being the router and AX86, the satellite in AiMesh. I’m considering to go with 2 same units of one or the other thinking two (2) Tri-band units is better than a mix match. I’d have the extra 5Ghz band for wireless backhaul. Currently the AX 86 and AX92 are wired with 1Gb. But then, the AX92 does have multigig. Thoughts? Thanks.
