Internet/network not working

[MadLittleMods]

My wired internet connection just stopped working after I came back overnight. This has happened multiple times before where I just restarted my computer to get going again but would be nice to get to the bottom of the problem.

I noticed that when pulling up the Network Manager GUI, it was just blank.

Blank network manager (internet not working)	Network Manager when things are working

And then checking on the NetworkManager service, it wasn't even running:

$ nmcli
Warning: nmcli (1.44.2) and NetworkManager (Unknown) versions don't match. Restarting NetworkManager is advised.
Error: NetworkManager is not running.

$ sudo systemctl status NetworkManager

Start NetworkManager

Starting NetworkManager again got everything going :white_check_mark:

Anything interesting in the logs?
