I'm having several problems with the Wifi connection and management of Ubuntu.
In the settings pane under Wi-Fi I can't connect to any other Wifi than "Die Anstalt". When I click any other Wifi, nothing happens and it tries to connect with "Die Anstalt" again (even if I didn't check "Connect automatically").
The Wifi is very unstable in general, it constantly disconnects after some time and then tries to reconnect but asks me for the Wifi password. I've read that this was an issue in the kernel version 5.15, but I'm using version 5.19.
I've looked this up and there are some solutions to it, but none of them seems to work for me as the issue persists.
What I've tried so far:
- Changing the value of
/etc/NetworkManager/conf.d/default-wifi-powersave-on.conf (tried other values, the standard was "2")
- Reinstalling the network manager (
sudo apt-get reinstall network-manager)
- Reloading the wireless module (
sudo modprobe -r rtlwifi && sleep 5s && sudo modprobe -a rtlwifi)

Alas, nothing seem to work in the long run, the issue persists.
