I have one Windows XP system out of 5 that is not connecting to the network. All connected to the same modem. I tested the cables and then switched it out with another systems connection and it still will not connect.
Near the where you put the cable in to the NIC are normal two green lights. What does only one green light at the top mean? I have a few other systems all working and their NIC cards have two green lights.
Could the NIC be bad or could it be something else that I did not think of? Should I try reinstalling it.
