[Ham-Computers] Network Problem

[WØQFC]

To the list members, I need some help!

I have the following setup:

Cable modem, Belkin 4-port router and three computers for the Ham Shack 
network.
The 'main' computer (that the modem is connected to) has a second NIC card 
which I want to use for a second network to run three other computers in 
various parts of the house (All hard-wired with CAT-5 cable). From the 
second NIC it goes to a Hub and then to the other computers.
The problem is that the status for the second NIC shows "Limited or no 
connectivity" and I am unable to connect to the Internet with these 
computers.
In researching Window help, it tells me that I need to use a network bridge 
to allow the two networks to communicate with each other and tells how to 
accomplish this. When I try this, it tells me that I can not have ICS 
running on either of the two connections.
I am unable to remove the ICS and add the bridge.
The first network is working fine and each computer can see the other 
computers. When I try to run the 'home networking wizard' for the second 
network it screws up the first network and I have to redo the whole thing.
Any ideas out there?
Thanks in advance....
