I was hit by lightning, it stopped the ethernet on my modem working so I got another one. Still no good so I got a gigabit PCI network adapter. The LEDs light up on the back of it but I do not know how to tell the computer to use it. I got a CD with several windows installations and a Linux one but all instructions are for widows and their tech support only new windows. I have opensuse 12.3 and can do a few things but don't know a lot.
