[ale] Making a wifi connection from the command line?

[Wolf Halton]

Wifi on Ubuntu is usually a simple nm-applet in the notifications-bar
issue: choose the wireless network you want and connect - enter the
password and it automagically connects to that Wireless network every time
you go there, forever and ever, amen.

I upgraded UbuntuStudio 13.10 to 14.04Beta over the wire, and there were a
few problems with the Xfce desktop (standard on UbuntuStudio).  The
nm-applet is running but no icon is visible in the notifications box.  The
Dropbox icon and Copy.com icons are missing as well.

I cannot find an cli command to get me to connect to a new wifi network.  I
would like to find a cli command to do this.  Hard to believe this is not
an included functionality.

Would I be better off just to install the whole Gnome desktop and see if
the notifications work correctly there, or backing up /home and bare-metal
installing UbuntuStudio 14.04 again?
