Networking help

I need some help if anyone can...

I have a 5 day old install of Fedrora10 and had set the system up to use KDE 
but now have went back to GNOME.

Before the switch back to GNOME I had the wired and wireless networking 
running great with both being found and active.

Now that I have made the switch , I can't seem to get the wireless 
networking to function.

When I go to Network Device Control nothing happens.
When I go into Network only the WIRED (eth0) to function but nothing from 
the wireless system.

Also I remember from past linux tries, there was a icon onthe top row of the 
screen beside the users name that let you control the networking actions but 
it is not there?

ANy help would be much appreciated...
