First off I don't know a lot about computers. I have an old Dell Deminson 4550 desktop computer. I reinstalled windows xp on it from the cd. Turns out I am missing the cd that you use to reinstall the drivers. Would I need this to establish an internet connection? I hooked up the modem and router, and I can get internet on my laptop but not the desktop. If it is working on the laptop shouldn't I be able to get it to work on the desktop or do I need to wait till I get the disk with the drivers and utilities on it? Thanks in advance for any help. Angel
