Beryl AX & mt7921u - USB phy-sta0 wedged after 24hrs

I am currently on my home-network where I am trying to recreate the problem, but without success. With the same config the stick works perfectly fine for almost 3 days now. There is something specific to the hotel environment that triggers the problem roughly every 24hrs.

Any further suggestions what to enable before the problem reoccurs and what to collect
when the issue happens?

Thanks!

Hello All!

I am back at the location where I can reproduce the issue. I currently have left the device in the broken state. From logread, this is when it happened:

Please, advise what to collect before i reboot the device to recover.

Performing an SSID scan does not show any output just spinning wheel… Thanks!

Update: The UI is also extremely slow and fails to load as well:

Bad Gateway

The process did not produce any response
