Wireless
I didn't end up having luck with iw, but I'm sure it is very useful. It seems I just wasn't able to interactively enter a password, so in the end I couldn't connect to WiFi. Worth looking at iw though.
sudo iw dev wlp0s20f3 scan
sudo iw dev wlp0s20f3 scan | grep SSI
sudo iw dev
sudo iw list
sudo iw wlp0s20f3 connect "Reed WIFI-2G"
See examples in man nmcli-examples. A lot of good information between this page and the SEE ALSO section at the bottom.
