ZenWiFi Pro XT12 vs ET12: Two Identical yet Completely Different Mesh Options

Share what you're reading!

If you’re confused between ZenWiFi Pro XT12 vs ZenWiFi Pro ET12, you’re not alone. Differentiated by a single letter, their model names seem to be a mean trick Asus plays on us all.

While there are a lot more similarities between these two than their monikers, they are also very different mesh systems.

This ZenWiFi Pro XT12 vs ET12 matchup — intended to be the supplement to their in-depth reviews — will help you walk away knowing exactly which to buy.

And that’s important because while each can be excellent in its own way, getting the wrong one for your situation will prove problematic, to say the least, considering they are expensive hardware to boot.

ZenWiFi Pro XT12 vs ET12: More than just a letter apart

These two mesh sets have just one letter in their name that sets them apart: XT12 vs ET12.

Per Asus’ naming convention, X is short for Wi-Fi 6 (802.11ax), and E is for Wi-Fi 6E (802.11axe). The letter T signifies that these are Tri-band broadcasters — they both have three Wi-Fi bands.

Physically, the two look identical. You can only tell them apart when you turn them on. Now the light on their “fronts” — it’s hard to know which side is the front — will show their full name. You can also check their undersides where their models are printed.

And there are even more similarities, as you’ll note in the hardware specifications below.

Hardware specifications: ZenWiFi Pro ET12 vs ZenWi-Fi ET8

ZenWiFi Pro XT12 vs ET12: The third Wi-Fi band changes everything

While both are Tri-band hardware, they are of two different types.

The ZenWiFi Pro XT12 is a traditional Tri-band with an additional 5GHz band (the 5GHz-2). So it has 2.4GHz and two 5GHz bands (5GHz-1 and 5GHz-2).

Dual-band vs Tri-band vs Quad-band — what’s really going on?

ZenWifi Pro XT12 vs ET2ZenWifi Pro XT12 vs ET2 LIghts On
ZenWiFi Pro XT12 vs ZenWiFi Pro ET12: You must turn them on and look at the front lights to know which is which.

On the other hand, as a Wi-Fi 6E device, the Zen Wi-Fi Pro ET12 has a 2.4GHz band, a 5GHz band, and a 6GHz band.

Additionally, on the 5GHz-2, the XT12 supports the latest UNII-4 portion to have a third 160MHz band which is free for DFS channels. By default, the ET12’s 6GHz band doesn’t have to deal with DFS.

The way they are, the ET12 must use all of its three bands for clients; it can’t dedicate any of them solely for the backhauling job. Consequently, in a wireless backhaul setup, whichever band works a the backhaul will lose 50% of its bandwidth — it’s the inherent signal loss.

In the case of the XT12, the 5GHz-2 band can work solely as the backhaul, allowing all bands to work at their full capacity. And the support for UNII-4 means the backhaul can consistently deliver the best possible performance.

UNII-4: What 5.9GHz is and how it matters in a mesh

While you can use both mesh systems with wired- or wireless backhauling, the XT12 is designed for a wireless setup, and the ET12 works best in a wired environment.

And that’s the most significant difference between the two. One more thing: the ET12 is $100 more expensive.

ZenWiFi Pro XT12 vs ET12: Can I use both together?

Technically, we’re supposed to be able to use the XT12 and ET12 hardware together in a single mesh system, per the way AiMesh works. And eventually, that likely will be the case.

ZenWiFi Pro XT12 No Playing Well
The message I got when adding the ZenWiFi Pro XT12 to my GT-AXE16000 Wi-Fi 6E (or the ZenWiFi Pro ET12). While this might change, it’s not a good idea to mix Wi-Fi standards in a mesh system, anyway.

For now, in my trial, that was not possible yet. No matter how much I tried, I couldn’t link them together. The AiMesh setup process would just fail every single time. And I tried many times.

And I couldn’t add the XT12 to my GT-AXE16000, either, which has worked very well with my ET12 set — as mentioned in this post on AiMesh combo with Multi-Gig backhauling.

While all this will likely change via firmware upgrades, mixing Wi-Fi standards is never a good idea in a mesh setup, and you should only do so, which you shouldn’t, with wired backhauling. Else the management of different Wi-Fi “banding” can get too complicated.

ZenWiFi Pro XT12 vs ZenWiFi Pro ET12: The two share similar performances as single routers.

In my trial, the XT12 and the ET12 delivered similar real-world performances. However, in a mesh setup, the XT12 is better because its backhaul band — the 5GHz-2 — is dedicated and has a much better range than the ET12’s default 6GHz band.

With wired backhauling — not shown here — they were very similar. And the support for the 6GHz band is the ET12’s advantage.

ZenWiFi Pro XT12 vs ET12: Which you should buy

You can buy either or none no matter your situation and the world will keep spinning for the foreseeable future.

But in case you’re contemplating between the two, here’s the recap for a smart purchase:

The ZenWiFi Pro XT12 is traditional Tri-band hardware. As such, it works great in a fully wireless mesh setup. You should get it if you live in a large home and are too lazy to run network cables.

The Zen Wi-Fi Pro ET12 is a new Tri-band hardware — it works best with wired backhauling. Get it if you intend to use a network cable to link the hardware.

If you use them in reversed situations, they will still work. It’s just a matter of degrees, of which the satisfaction level depends on how carefully you’ve read this post and the hardware’s in-depth reviews.

If you only need a single unit, my take is the ET12’s support for the 6GHz band is more valuable than the XT12’s support for UNII-4 (or the fact it has a second 5GHz band). But either will do just fine and you’ll save some dough going with the XT12.

And, like always, the call is yours.

Need to save even more, consider the choice between the ZenWiFi XT8 vs ET8.

  1. Hello Dong-

    I have a ASUS XT8 Mesh system (6 nodes total). I am about to the main router to either an XT12 or an ET12 and want your input.

    I have 2gbps internet service, and have cat5e drops throughout the home. 3 of the NODES are using wired backhaul and 3 are using the dedicated wireless backhaul.

    I am uncertain whether I should purchase the ASUS XT12 or the ASUS ET12.

    Why do I have so many nodes – the home is large and the zones are compartmentalized throughout . . .

    The Router is in a “Networking” closet with a networking patch panel (so not great for transmitting via WIFI.

    The Nodes are strategically placed to maintain coverage throughout the various sections of the house (interior bedrooms, living room, family room, dining room, interior courtyard, backyard, and garage).

    Your thoughts would be greatly appreciated.

  2. Hi Dong, thanks again for the illuminating comparison.

    I am considering to buy two XT12/ET12 units as well.

    I live in a rural, three-floor house (about 300m2), so there is little issue of channel congestion. The nearest airport/weather station is about 20 km away so I hope that keeps DFS events at a minimum (I don’t know if I can get this info from the router logs). I do not have many wireless devices (<10).

    Do I understand correctly that in my case the 6GHz band would be more or less useless and I would benefit more from the 2nd 5Ghz band when I use the wireless backhaul? I do want a wired backhaul in the future (but not in this house).

    Thanks a million,
    Francois

    Reply
    • You can use 80MHz channel width and turn off DFS completely, Francois. If you have wired backhaul, the ET12 is the best, if not the XT12 will do. In the latter case, you can use UNII-4 160MHz as the backhaul link if that’s available in your area, (it might not.)

      And no, I’d not count on the 6GHz as the backhaul.

      • Hi Dong,
        Thank you very much for your answers. About the availability of the UNII-4 bands; in the EU I was not able to find conclusive documentation about that. Some sources (https://en.wikipedia.org/wiki/List_of_WLAN_channels#5_GHz_(802.11a/h/j/n/ac/ax)) seem to suggest that anything higher than channel 173 (5865 MHz) is unsupported, but lower channels are (but at a lower power).
        ASUS itself does not indicate what is actually supported on the XT12, only that ‘some frequencies might not be available in your area’, which is extremely difficult to figure out.
        It would be very nice if someone living in the EU (preferably France) could confirm what channels are available on the XT12. If it cannot be cleared up, my preference would also be the ET12 since at least the 6GHz band is only unavailable for the top half.

        Reply
        • Then I’d go with the ET12, Francois. It works quite well as a fully wireless system — as you can see in the performance charts. Then run a network cable to link the hardware units at some point. Network cables work the same everywhere. Good luck!

  3. Hi from Italy Dong, I really love your website! Please, can help me in the choice for upgrade my WiFi?
    Now I’m with Fritzbox 7590 connected via wan to Ont on 1st floor. I also have Fritz repeater 3000 via ethernet backaul on 2nd floor. Ftth 1 gigabit, maybe one day I will have 2,5 gigabit. It works well…
    but I would increase network with WiFi 6 or 6e. i love xt12 but I suppose in my scenario you would suggest et12…
    Or… maintain actual configuration and wait for WiFi 7?
    thanks!

  4. First.

    Thank you so much for these extremely informative reviews. Fantastic work!! Thank you-

    I have a smart home with ~150+ wired devices from lights to oven,etc.

    I’m planning on getting the XT12 based off my research and your reviews.

    Question:

    Wireless bachauling. For all the smart home devices do I connect them specifically to the 5g network? Is there anything I need to do for things like light switches that do not use a lot of bandwidth but will always be connected? Or do I just connect everything to the Wi-Fi and Asus software will set up as needed?

    Thanks so much for everything you do.

    Sincerely-

    Reply
      • A couple of things, Banks.

        1. 150 are a lot of devices. A system can handle about 250 but due to the standard 24-hour IP reserving, one device might occupy two or more addresses for a period so 150 is pushing it. To avoid issues, it’s best to use IP reservation in your case.

        2. Wi-Fi smart home devices tend to use only the 2.4GHz band and are generally terrible for your network. Most of the time, you can’t connect these to the 5GHz.

        So in your case, it’s hard to say. The linked posts above you help you figure out what to do. If you have 100 or so of those dumb “smart” devices, no Wi-Fi router or mesh system will work well.

  5. Thank you for this great article! I have two XT12 with wired backhaul and I was considering adding a ET12 unit with wired backhaul as additional satellite, did I understand correctly that currently it won’t work? Thank you

    Reply
    • That didn’t work in my trial but that might change with new firmware, Andrea. It’s best that you go full ET12 in your case, though. It’s best not to mix Wi-Fi 6E and Wi-Fi 6 in a mesh.

  6. Hello from France !

    Many thanks for your fabulous website that I love! you are a king.

    I have to install wifi at a client who is lucky enough to have a very large domain.

    I explain his situation:

    his house is atypical.

    it has a very large plot, on which several houses are located. (5)
    they are all wired together. (ethernet)
    area: 200m2 (2100) per house.

    the houses form a circle and are all about 50m (164 ft) apart.
    He wants internet in all the houses (5 houses)

    Please what would be the best solution?

    I was thinking of installing 5 ZenWifiPro XT12 (E12 not currently available in France)
    Or XT12 and XT8 combo?
    I read that E12s were recommended when everything was wired.

    In any case, only one XT12 per house will suffice and I think that in wifi links, they will also see each other even at 50m (164ft) from each other

    Thank you very much, I hope I was clear!

    • You’re welcome and no I’m not a king. πŸ™‚

      But even if I was, I generally don’t comment on the specific situation… Read this post carefully, including the reviews of the hardware involved, and follow the other posts in the related box at the top of the page, such as this one on mesh systems, and you’ll be able to figure things out. Again, make sure you read them from the top to the bottom, and don’t skip around.

      Bonne chance!

  7. Thanks for the comparison Dong. I am leaning towards ET12 with wired backhaul but I will need 2-3 additional units in my house. Buying another ET12 pack will be expensive or so which other model do you recommend I use with it?

    Reply
  8. Many thanks for this comparison, I found it very helpful. Since I intend to configure using a wired backhaul, I am leaning toward the ET12 (per your recommendation). However, several of the computers I will be connecting wirelessly are likely too far away to benefit from the 6GHz band due to its limited range. Additionally, I live in the heart of the city (with neighbors in close proximity with their own wireless setups). In such a case, am I better off with the XT12 (in a wired backhaul configuration) because of Unii-4? Either way, I think it’ll be a huge improvement over my current setup. Many thanks again.

  9. I’ve been using 4 x XT12 for the last 4 months via wireless backhaul and very happy so far – they have native Merlin firmware support and have been much more stable in my environment than a combo of 2 x AX11000 and 2 x XT8 I used before.

  10. Thank you for correcting me! Up until reading your article I thought they were the same, except one was a 1 pack and the other was a 2 pack!

    Reply
  11. Very useful comparison, thanks. Even with a wired backhaul setup however, given there really aren’t very many 6GHz clients out there and that 6GHz has substantially worse performance at distance that 5GHz, don’t you think there is an argument for an XT12 based mesh in that you are gaining a lot more 5GHz capacity in an environment where one has a lot of wireless clients all operating at the same time so you spread them across both 5GHz bands?

    Reply
      • So I read just re-read what you wrote on using two 5GHz bands and my situation may be somewhat not unique but not common, but I live in an area where there is very little contention for 5GHz wavelength (I live in the outskirts of a not very big city which also means that while I can still get Xfinity Gbps service the number of homes serviced by a neighborhood node is pretty small so even busy times don’t have much Internet contention) so pretty much all of the 5Ghz channels are free and clear. In this case, where I assign different SSIDs to the two 5GHz bands and I’m prepared to manually load balance the clients by only giving them access to one or the other 5GHz band, doesn’t my argument hold water?

        Reply
        • It does, Randall. But like I said, your mileage will vary since Wi-Fi is invisible. Chances are you’ll experience no difference one way or the other. But generally, it doesn’t hurt to have that “extra” band. Having an entire 6GHz band is better, though. So get the GT-AXE16000 if you want to have both. πŸ™‚
