Question about wifi6 dual vs tri band

[shoman94]

So I currently have an AC88U and a Netgear r7000 connected via Ethernet for the backbone. I have some devices that use wifi6 bit I don't necessarily need wifi 6. I want to replace my r7000 because I'm having problems with it. I'm looking at the ax92u kit (maybe sell my 88u) and I see that it is Tri-Band allowing you to use wifi6 for one 5g band, wifi5 for the second wifi band and then 2.4 wifi5.

I guess my question is what's the difference with separating wifi5 and 6 bands vs having a dual band only wifi6 router? Does it run simultaneously wifi5 and 6 on the same band?

AX92U is like all tri-radio routers. One of the 5 GHz radios covers U-NII-1 channels (36-48), the other covers U-NII-3 channels (149-165).

ASUS designed the AX92U this way to maximize throughput for backhaul.

Yes but I'm asking about a Tri-Band with only one band broadcasting wifi6 with 2 wifi5 bands vs a dual band wifi6 router

A Wi-Fi 6 radio is generally backward compatible with earlier Wi-Fi versions.

Yes I get that but would overall performance be better if you have a Tri-Band with a dedicated wifi 6 band vs a dual band with mixed wifi5&6 devices on the 5ghz band.

Unlikely. Both AX and AC devices support the same link rates in 5 GHz.

I run an AX92 with my old AC88 as an wireless AiMesh node (flaky WAN port). The only drawback is no Merlin.

A WiFi6E radio is not...

Interesting note that WiFi6 in 2.4GHz likely will cause issues...
