I got a question. I got two computers, one has a cable modem and works fine, i have my lan wire hooked up to the hub which has the cable modem wire hooked up to it. Now, the other computer also has a fully functional wire, which i tested on my working computer, but, this will not connect to the internet lan that we have set up. It was working fine a few days ago but now it's not. I am sure the wires are in the right slots and i have checked over and over again. Is this just a problem with the computer or is it a hub or connection problem?
