And after that device shows up nmcli can be very useful:
 nmcli device

will list your network devices

if it is not enabled - unless it it is physically switched off -
you can unblock it with

 nmcli radio wifi on

and to connect
 nmcli --ask dev wifi connect <your-network-ssid>

it will ask for your wpa password and by default will remember it.
