My SO’s wifi is called “Connection not possible”

I second that. Ask 5 people, get 10 answers and the others are obviously wrong.
Also everyone should use Linux and everything can be done via GUI, but I obviously use terminal for everything so i can’t tell you how to fix it in GUI. Oh, sorry, you need to know how to use the terminal for that specific error you are having.

Aaaand it’s people like you who make other people hate vegans.
