[SOLVED] Upgraded to Kubuntu 22.04 (from 20) and now wireless is gone (lots of logs included)
by teefz from LinuxQuestions.org on (#6D9G8)
Wireless was working fine on the previous version of Kubuntu. Now that I've upgraded, I am unable to see any wireless networks.
The obvious thing I see is that the adapter is disabled, but I am unable to enable it.
Here's some info:
