Please help! DSL Modem to Hub Failure

My brother just got DSL service that allows shared internet access. The DSL modem was provided by the ISP and he had to buy the hub. To ensure proper setup he followed first he connect a cable from the wall jack to DSL modem, then from the modem to computer's NIC - no problems, he was surfing away on the Internet. So he proceeded to attach the hub as follows;

1) He unplugged the cable from the computer's NIC and connected it to 1 of the 4 hub ports (10Base), with the other end of the cable still connected to the modem

2) Followed by connecting a cable from another hub port to the computer's NIC

No luck. He noticed the status light on the computer's NIC to the hub port was lit, meaning connection established. However, the light from the DSL modem to the hub were both off (meaning no connection established, right?). So the problem is the communication from modem to hub. He tried swapping out a new cable but still no status light.

I at a loss since the status lights for a modem-NIC connection and lights for a NIC-hub connection, but fail for a hub-DSL modem connection.

Anything he's doing wrong? Thank in advance for any feedback.
 
When you say allow to share.

They give you few IPs, or they just don?t mind that you share?

What form of authentication they use (i.e. PPPOE involves).

Did you use an Uplink or regular Port?
 
I also don't understand what you mean by "share." Any connection you get you can share, you might have to set up NAT or whatever, but it can be done. Are you saying that the Modem has a NAT like feature? What type of modem is it? Did he plug the cat5 cable from the Modem to the Hub into the uplink port(not that this will do you anygood if the modem doesn't use NAT)? Or do you need to setup your own NAT?
 
Probably need a cross-over cable (or use the uplink port on the hub, if it has one) to make the modem -> hub connection.

Think of it this way (kinda half-baked logic):
Device A (NIC) connect with straightthru to Device B (hub) = PASS
Device A (NIC) connect with straightthru to Device C (modem) = PASS

This means:
Device B port pinout = Device C port pinout

Which means:
Device B (hub) connect with straightthru to Device C (modem) = FAIL

Which also means:
Device B (hub) conect with crossover to Device C (modem) = PASS

FYI: If he's planning on sharing this connection with multiple PCs, he will need a router, not a hub...in which case he may not need a crossover cable.
