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?
