Wifi Keeps dropping

[clever_duck]

Hello,

I've got RT-AX92U one running downstairs connected to the modem and the other upstairs connected via AiMesh. Over the past week or so wifi keeps dropping for some reason. I don't recall anything changing.
If I upload the syslog would someone be able to point me in the right direction? Not sure if uploading log files is allowed here.

I have a fairly complex home network here with over 25 devices, a NAS drive, a Pi Hole, etc. Router not pointing to PI Hole, used as stand alone for now.

It's dropping on all devices so I'm sure it's going to be the router than the device.

I've rebooted both the router and the modem many times, still same issue.
Currently on fw 3.0.0.4.386_43084

Guessing it's getting too hot that is one of the reasons. But it has been working ok up until recently.

Make sure you have the WIFI set to fixed channels, 2.4 and both 5 GHz bands.
Avoid 5 GHz DFS channels.
Use Dual Band SmartConnect.
Try dropping the 5 GHz bands back to 80 MHz
You should be able to make the changes without redoing the AiMesh. Good idea to reboot the mesh afterwards.

Your router is overheating. The CPU reaches 100C and thermal protection shuts down the cores.
