Ubuntu desktop - Main panel

[Geoffrey]

I have carelessly deleted all icons form the main panel. I have managed
to get them back with the exception of the one used to connect with the
Internet. It's the one that changes to an antenna when connection made.
Can someone tell me where this connection source is so that I can add it
to the panel. Note that I am now connecting (Wireless Broadband) via
Network Connections which is a slow way.
