So we got dsl a few weeks ago. It was easy to install on my laptop, just hook up the modem to the computer and that was it. Now I tried to put it on my parents computer but its not working. The modem we got has 5 ethernet ports in the back so what I did was hook up the ethernet cable to one of them and ran it to the back of my parents computer. When I hooked up the cable to the computer the thing "Local area connection is now connected" came on like always but the two little monitors that it always shows were black. It also showed 0 sent and 0 recieved in the packets section. I made sure all the cables were right, I know the other ports on the modem work because i've used them for my 360 before but i just cant figure out how to get it to work on the other computer.
