I think that I'm really close on this. My wife's desktop got hit with some nasty viruses (she was less diligent about updates back when we were dating) and we had to reinstall WIndows XP. We haven't been able to reconnect it to the internet since. The machine itself is an old Dell Dimension 4600. We have the drivers CD, but Windows has not been finding the driver on it.
I've been going in by right clicking "Properties" on the My Computer icon to get to the Device Manager. It looks like the only driver that I'm missing is for the Network Controller under Other Devices (has a question mark next to it)
Based on other searches around the web I've found that the driver should be located in the c:\dell\drivers\R56237\Drivers\WinXP\v5.30 directory. I copied the drivers from the CD directly here but they still aren't being seen when I have the wizard look for them.
One other note - my Linksys router is working fine and I have a cable running staright from that into the PC. Connectivity lights look good. No wireless networks are showing either. And even though the machine shows great connectivity from the cable, I can't connect to the Internet
That's as far as I've been able to get - what step am I missing here?
