Hi,

WiFi randomly is disconnected on ubuntu 24.04

uname -a

Not clear to me if these errors are related to disconnect. Please share
full log (via private mail if privacy issue). I also want to check the
firmware version you are using. 

Another try is to turn off power saving entirely by
  sudo iw wlan0 set power save off
