Any ideas?

I took a friends computer home to take off some spyware/adware/viruses. I used Pest Patrol, Hijackthis, Spybot, and Ad-Aware. After taking it back spyware free, I can get it to connect to the internet by going into IE/Tools/Internet Options/Connections/Setup and running the setup home office wizard. It connects after a few seconds of waiting. Then you reboot the computer. It comes back on, no internet. I gotta do the same thing to get it to connect. What the hell is going on here? Its going into a router.

Any ideas?
