Hi,
I'm about to give up on these routers as they are giving me hell.
Two AX92U with a network cable backhaul (AI mesh) setup with 3 separate SSIDs (2.4Ghz, 5Ghz and Wifi 6 only 5Ghz).
Routers run latest formal firmware (3.0.0.4.386_43084) but the same happened with previous two versions as well.
I did a clean manual install with a settings restore and re-added the mesh node after the upgrade to ensure a clean start.

The mesh is setup to reboot daily (5 AM) and I get a crashed 5Ghz wifi (no Internet) randomly every two-three days with the log saying:
kernel: wl1: fatal error, reinitializing, total count of reinit's[1]

Only a reset helps resolve this but I'm pretty sick and tired of not being able to trust the network to stay up.

Did anyone face this issue and resolved it?
I've already tweaked the settings over and over without any change to stability.

I suspect it's either a design flaw or a heat related issues (it can get hot here - around 30 Celsius when the AC is off).

Any ideas or advice before kicking the routers and getting something more reliable?

Try (as a test) to disable the 2,4ghz wifi to see if the fatal error messages disappears. It worked for me, and I do not need 2,4ghz Wi-Fi and the fatal errors in the log disappears. If I enable 2,4ghz again the messages reappears.

Thanks and I wish I could but I got a lot of devices here (smart home devices) that support only 2.4Ghz so I can’t disable it without loosing a lot of house functions.

I'm facing the exact same thing. Running Firmware Version : 3.0.0.4.386_41712-gf4ae027. Have a near identical setup as you. Two devices, connected via wired backhaul, running all three bands (most smart home devices on 2.4Ghz network). The only difference I have is I'm not using AI Mesh on the Access Point. I have it set up as a stand alone access point, but with the same network names as the main router, so it kind of acts like a mesh where devices can bounce between the signal from the Router and the AP, without being in Mesh mode.

I keep experiencing the same Kernel errors as you on the main router, and some of the devices on the 5Ghz-1 band keep losing their connection. 2.4Ghz and 5Ghz-2 seem to be ok and keep their connections. It's only the 5Ghz-1 band that seems to have the issue.

I also have both the Router and AP set to reboot themselves nightly at 4am, and I still get this occasionally during the day every few days. It's just a huge dump of Kernel errors messages all of a sudden.

Have you bee able to figure anything out?

Are you using a wireless backhaul?

No. Connected via WIRED backhaul. Router and AP setup.

All of the issues seem to be from people who use ethernet backhaul or operate them as AP's.

If you are using Router and AP mode, it negates the point of having the AX92u's.

The 92u's are for people who want to setup a full wireless mesh environment.

I imagine the reason you are having problems is because Asus didn't anticipate people would use them as AP's. I know it offers it in the admin but this is Asus.

If I was in your situation, I'd probably swap the 92u's for either an 86u or an 89x and combine with a good AP.

Obviously this is not the answer you want. All I can say is in full mesh mode with no ethernet backhaul they do work perfectly, the latency is only 1ms - 2ms more than ethernet.
