Other posts seems to be addressing more complicated network connection issues from the command line.
The Unity panel Network indicator/button doesn't respond too well sometimes - it keeps trying to connect to a network even when i click on "disconnect", stuff like that.
So I want to go command line for the control. I don't like GUIs anyway.
Is there not some simple command line tool which can do something like the following?
wifi connect MyNetworkNameA wifi disconnect wifi connect MyNetworkNameB
