, Dell XPS8100 windows 7. Came home the other night and internet was a no go. Traced it to this computer since other computers are still internet functional. I tried rebooting, uninstalling/reinstalling driver, system restore - still no go. In device manager it states that it's functioning, but it isn't. I figured I would install a new Ethernet card and turn off onboard card. Thinking a pci Ethernet card (I prefer wired). Any suggestions???
