 The little icon in the notification area is provided by a program
called nm-applet. You can run it by hand like this:

  nm-applet --sm-disable

The sm-disable prevents it from registering with the gnome-session.
You don't want to know.

This should be automatically started for you when you log in. Try
running the program gnome-session-properties. On the Startup Programs
tab you should see "Network Manager". If you don't, add a new entry
that looks like this:

  Name: Network Manager
  Command: nm-applet --sm-disable
  Comment: Control your network connections

I'm also assuming that NetworkManager is actually running. nm-applet
sends commands to the privileged NetworkManager daemon over DBus,
which actually does all the work.

  sudo service network-manager restart

If it's not running for some reason, you have other problems.
