    My PC is a laptop and I am using Windows XP Pro.

    If a situation arises where I have connectivity to 2 wans/lans or I am
    dialled-up (via NIC, WIFI and modem respectively) and both connections offer
    Internet connectivity, will this work? I can see that it would if each device
    (NIC, WIFI or modem) has an independent ip address but not if the laptop has the
    ip address.

    The interface (NIC) has the IP address - it's perfectly normal for a
    computer to be reachable on more than one IP address. I.e. my home network
    is 192.168.0.*, when connected to a client it is also on 192.168.1.*.

    As far as internet access goes - that depends on your route tables and the
    gateway. I'm not sure about XP, but on Linux you can specify (via the route
    tables) which interface certain traffic goes through.

  3. If a situation arises where I have connectivity to 2 wans/lans or I am
    Normally the last connection made will take over the default route and thats
    where it will
    send the data via.

  5. For a modern operating system, the answer would be "yes". For Dimdows
    .... who knows ...

    One of them will be the default.

    You can likely specific which one.....or it will default to whichever one
    the system rules thinks should be the default. That could well be the last
    one as activating it most likely included changing the default route.
