It'll be buried in there somewhere.  On my Gnome Ubuntu 14.04, there
is a "Wi-Fi Settings" thing, next to the networks I have connected to
is a little arrow.  If I follow the arrow I find a page with a
"Forget" button.

If you fail to get a DHCP address (when it is expecting one, as it
usually is) you will get similar behavior.

While it is spinning, try running iwconfig from a shell.  It should
tell you whether you are associated.  If you are, and it's still
spinning, then you don't have a DHCP lease for some reason.

You want wpa_supplicant or its close friends (maybe wpa_cli?).  Or
maybe you don't, but you asked, so there it is. ;-)
