Another possibility available to shell users is to run nmtui and activate
your chosen chosen connection. For Wi-Fi instances you'll need to know
and use the password and if it works you'll have a choice to delete the
connection or you could simply exit out of the nmtui program at that
point. In order to test the connection, the command:
ping -a -c 5 www.google.com
should perhaps generate some beeps and some packet transfer information
on the screen. If it says something to the effect connection unknown,
you don't yet have network up yet.
Hope this helps.
