I am running the GNOME 3 desktop environment on Ubuntu 11.04. I accidentally clicked the "Don't show again" option when a notification from NetworkManager came up, but would now like to have it back. How can I restore it?

Open terminal and type ‘gconf-editor’ then press ‘enter’, this will open the ‘Configuration Editor’ after that go to 1). /apps/nm-applets click on it , clicking on the right side will tell you what each file does.
2). /schemas/apps/nm-applets image of ubuntu config editor
Your NetManager could be set to 'hide' I do not know which 'box to tick to restore'.
'disable-disconnected-notifications' ?? Hope this works
