Rebooting with the AC power connected and the Ethernet cable connected doesn't help. What is the mechanism that turns the NIC card on and off? I have both Windows XP and Puppy Linux on the computer, and I'm unable to connect to the Internet with either OS. How do I tell if the NIC card is dead or merely asleep?
