Network icon not visible in Ubuntu 12.04
 
When I tried to configure a broadband connection in my Ubuntu 12.04 somehow the network icon has been removed from the system panel. I tried many kinds of solutions but still it is not visible. Now I am unable to add new connections.

How can I get the icon back?

Code:

And have you updated your system?
