Hello, and first of all I have to apologize because I have little data to provide for my issue.
I think there's something wrong with my WiFi interface using OpenWRT 23.05.2 on a Netgear X4S R7800. What happens, on a random basis and with several weeks in between, is that I find some of my WiFi networks disabled. I have configured a few, both on 2.4GHz and 5GHz, and they seem to just automatically disable on their own. Not all of them (again, on a random basis) and without any specific cause. I don't usually fiddle with Luci, and the admin password should be strong enough (16 random characters with upper and lower letters, numbers and symbols, saved to a password manager) to make me think it's not someone hacking in. Unfortunately I have no logs because I just rebooted it thinking it was just some kind of failure, but they were actively disabled even after the reboot.
I was wondering if someone could have a clue about what might be happening, although I know we don't have much to work on. Sorry again about that, and thanks for any hints!
Per regulations, 5GHz APs have to change to another channel (or disconnect, if that is not possible) if it detects a nearby radar (DFS).
Don't think so, since also 2.4GHz disables itself.
I was wondering, could it be somehow related to overheating? Is there a way I could understand this? Is there a reference temperature where routers are known to disable their wifi interfaces?
Next time wi-fi goes down, log into LuCi with a wired connection to look at system logs.

Finally I managed to do this after having had this issue a few times. Since it's still apparently totally random, I needed this issue to happen while being at home and quick to react, or the logs would fill up quickly. As I said, this time I managed to get logs. This is the related part in system.log:

Finally, I installed collectd-mod-thermal and noticed a spike on both CPU Usage and temperature around the timing when the wifi disconnected.
There have been numerous threads on this subject and I have encountered it myself.
You may have a faulty router, but my guess is that you have a failing power supply. When transmitting, the power demands increase dramatically for a few milliseconds. A slowly deteriorating power supply may suddenly drop its output to a level where things inside the router stop working eg the "chip" taking the burst of extra power.
As the deterioration progressively gets worse, the router may even start to randomly crash...
It is worth testing with another power supply if you have one.
