Recently, I re-installed windows XP on a newly formatted hard drive.  I tried to use the network setup wizard to create an internet connection via  a cable plugged into back of pc but the wizard says that it can not detect network hardware.  I believe the network card is built into the Motherboard. I tried to isntall drivers from the Dell Cd that came with the system but it fails to detect a modem.  My system is a Dell dimension 5150    Suggestions are greatly Appreciated. 
After Windows XP re-install, I can not set up an Internet connection.
