Nmcli

Did have an issue with nmcli, even when entering SSID and Password the connection was refused with ‘secrets were required but not provided’

Found solution on StackExchange

nmcli con delete <SSID>

and setup connection with

nmcli dev wifi connect <SSID> password <password>

nmcli is preferred to nmtui where each time the SSID must be selected and password entered.

Some other basic nmcli stuff
