I'm running 22.04 and I have troubles connecting to a WiFi network. The problems manifest differently every time, but right now it's in a state where Network manager says connected, but I cannot ping a server. My WiFi quality is pretty bad, but that is not the culprit as connecting on Android and on Ubuntu an live USB works just fine.
I've even tried reinstalling network manager in case it's its fault (installed network manager snap, removed network manager apt, rebooted), but the same thing happened. It must be some configuration deep in the system that has been changed long time ago (so the Timeshift snapshot won't cut it).
