Hi I am having an issue with a desktop computer getting online. There is a cable modem connected to a belkin wireless router. No matter what lan port I plug the desktop in I get limited connectivity. If I plug the desktop directly to modem I get connected. I confirmed that the ports on belkin router are working with a laptop. I tried another ethernet cable to computer and get same resultswhen I do a ipconfig there are different letters like "fffefeefeff" for ip . What would caused this desktop not be able to connect while plug into belkin router?
