Your post mentions a 5 port hub.
That means you have one pc with two network cards. One network card connects to the dsl modem, the other connects to the hub. The other pc and laptops all connect to the hub.
Am I on track here?
Have you though of using a broadband router instead? They normally incorporate a 4-port switch, which routes traffic more efficiently than a hub. It is also easier to configure and may save the hassles you are experiencing.
I know, I sound like a salesman, not really offering help, heh, but they really do simplify networking.
