GNOME NetworkManager Applet
GNMA is rubbish.
Uninstall it and install wicd
If that doesn't work for you, it is really easy to edit the /etc/network/interfaces
file manually to do all the work for you to set up an internet connection.
You could also search LQ (see, above - [SEARCH]
) for my username and the term /etc/network/interfaces
to see many examples of how to do this.
