How do I beat this stubborn hub?

I'm trying to set up a simple, two computer network in my home but cannot connect to the internet.  Any ideas as to where to go from here?

Road runner (cable) is my ISP and they do allow home networks of up to three computers.  I am running windows XP on my main machine and windows 95 on the other machine.  The winxp machine has all network protocols, and network clients installed.  The hub I bought is a 4 port 3com OfficeConnect 3c16723a.  I did not get the software that is supposed to come with this hub.  The network card in the XP machine is a 3com 3c918 Integrated Fast Ethernet Controller (3C905B-TX Compatible). To get things started, I just want to connect my main machine (winxp) to the internet through the hub.

These are the configurations I've tried.  For each setup, I've connected the modem cable to each port, and the PC cable to each port.  So I've tried every port/cable combination.  None of these allow me to connect to the internet.  I've already returned one of these hubs, because it was displaying the same symptoms and I didn't think it was working.  Now, I'm thinking it's my fault.

Configuration 1
I have an standard ethernet cable coming from my cable modem to my hub.  I have another standard ethernet cable coming from my hub to my PC.  The uplink switch is not pressed.

Modem Status:
Power light on (OK)
Cable light on (OK)
PC light off (Not OK)

Hub Status:
Power light on (OK)
PC port light on (OK)
Modem port light off (?)
Activity light blinks occasionally (?)

Configuration 2
I have an standard ethernet cable coming from my cable modem to my hub.  I have another standard ethernet cable coming from my hub to my PC.  The uplink switch is pressed.

Modem Status:
Power light on (OK)
Cable light on (OK)
PC light on (OK) (even without the PC plugged in)

Hub Status:
Power light on (OK)
PC port light on (OK)
Modem port light off (?)
Activity light blinks occasionally (?)

Configuration 3
I have an crossover ethernet cable coming from my cable modem to my hub.  I have another standard ethernet cable coming from my hub to my PC.  The uplink switch is not pressed.

Modem Status:
Power light on (OK)
Cable light on (OK)
PC light on (OK) (even without the PC plugged in)

Hub Status:
Power light on (OK)
PC port light on (OK)
Modem port light off (?)
Activity light blinks occasionally (?)

Configuration 3
I have an crossover ethernet cable coming from my cable modem to my hub.  I have another standard ethernet cable coming from my hub to my PC.  The uplink switch is pressed.

Modem Status:
Power light on (OK)
Cable light on (OK)
PC light on (not OK)

Hub Status:

Config 2 is correct, but oyu need the software setup.

Leave just the TCP/IP protocol.

Use the same Groupname on each machine.

Post the result of

ipconfig /all

from a DOS window.

I hope this helps !

Most (if not all) cable vendors out there require that you register your MAC address with them before your machine will be allowed to function on their network.  Did you register any MAC addresses with them?  If so, for which machine?  Are you testing with this machine?

Any idea where I can get the software?  I cannot find it on the 3com website to save my life.

RR does not require MAC addresses to be registered.  I have set up a few networks on RR before without doing that.

It's a 10 mb modem and a 100mb only hub.  They cannot talk to each other.  DOH!
