good that it is working now 
this link doesnt seem to be working for me? [quote=“thxstr, post:4, topic:13390, full:true”]
At least something like “nmtui” ( https://www.howtogeek.com/devops/how-to-manage-linux-wi-fi-networks-with-nmtui/ ) would be helpful for the point 2 (the editing), but even that seems not to work!?

Please check if the installation of the network-manager (and I wanted to have the network-manager-gnome as well) will automatically install nmtui .
