I am having a problem with a cable modem, surfboard 4100, I cannot get online when it is hooked up to either one of my pc, I also noticed that when it is plugged into the ethernet card, there is a green light, but also a yellow light goes on. When I hook up a 3com modem, it is fine. The surfboard was working ok, then I had to move the pc and noticed that the ethernet card and popped out of the slot, so I took it and placed it in another slot, so of course when I put the pc on windows found new hardware, so then in the control panel/windows/system there were two ethernet cards listed so I removed them both, removed the card and started all over again, still no luck . The surfboard will still not work on either pc.Any help would be greatly appreciated. I am running windows 98 se
