    actually, you can only use one NIC/computer effectively; attempting this
    router -+
            + ----- SysA.Nic#1
            +------ SysA.Nic#2
    looks like you should get twice the thruput, but this is far more difficult than
    most users can configure. It takes special software to split a connection between A-B so
    that traffic flows on both NICs.

    Dual NICs can be used like
    where sysA needs them to allow sysB access (this is the ICS solution)

    You can also get
    to work by purchasing a second IPS license and a different getting a different GATEWAY address.
    The this will cause routing to be selected base upon the HOP count difference
    of the two gateways. However, all traffic for connections A-B will flow thru one OR the other, not both.

    I'm a bit confused with your question.

    Care to give more details?

    Why do you need 2 network adapters in each computer?

    Have a look at this thread and see if it helps answer some questions.

    You need to leave one enabled and one disabled.

    And you need to give more details and a more full explanation of what you're trying to do.

    With a wired ethernet or a wireless connection, you do not install a router on every computer!
    The install software is necessary ONLY if you use the USB
    connection, and then you can only do that for one computer.

    On the computer that is not connecting to the router, you need to ensure:
    the device is operational and there are no yellow/red flags
    go to your Device Mgr and verify Network Adapters.

    When connected, the adapter should have a green light next to the cable slot
    you used. If not, then the cable is bad or the adapter is not 'active'.
