Title:
Ubuntu 18.04: Wifi adapter not detected after kernel update
Status in linux package in Ubuntu:
Incomplete
Bug description:
"lsb_release -rd" output:
Description: Ubuntu 18.04.4 LTS
Release: 18.04
So, my linux kernel was updated to 5.3.0-40 today, and my wifi adapter is no
longer functional. When I run "lshw", the usb-1 device is detected, but is
"UNCLAIMED".
Booting with the previous kernel works, so I figured it's a kernel problem.
