I think he might be talking about his wireless antenna that is in the bottom right hand side.
if thats what you are referring to then once you logged on to the internet with the auto-connect you mentioned go to your
MANUFACTURERS WEBSITE ex.(HP, Toshiba)etc..
Look for DRIVERS FOR YOUR COMPUTER
DOWNLOAD THE drivers for the WIRELESS CARD that is missing.
Install and you should see the antenna symbol once again, if that is the one you are talking about.
But maybe the symbol is not showing because it was removed from the windows bar. So in that case make sure you can put it to show back again.
