Ubuntu Version:
Ubuntu Studio 24.04.2 LTS
Desktop Environment (if applicable):
KDE
Problem Description:
The WiFi works for a while until it does not. At boot it works fine, but after a while the following dialog appears, and wifi shuts down. Ethernet keeps working if I connect a hub and a wifi cable. Its not the hotspot that stops working, since my android phone, iPad all connect to it fine without any issues.
Ocasionally the touchpad also seems to stop working, and it seems related, but its not 100% overlapping. However the touch screen never stops working. My main goal for now is wireless, I just mention the touchpad issue cause it may help the diagnostic.

What I’ve Tried:
I have also tried the latest version of Ubuntu (not the LTS, not studio flavor), and the latest version of Linux mint, and all have the same issue. I searched the forum for this and found no topics. Around the internet posts like this seem to suggest upgrading the kernel, but i’m on 6.11 that should be recent enough.

In any case I need a low-latency kernel, maybe those don’t have the correct tree merged in? maybe someone could confirm this…
Thank you very much for the time reading this post.
