two networks sharing 1 cat5 cable

    Hi all,
    I have a private network with 192.168.1.1 as the gateway.
    We are looking at a new program that is wireless and the vendor wants their
    network separate from ours, but they want to use a splitter to be able to
    share the same cat5 drop. They are using 192.168.1.2 as their gateway.
    We will have a computer for our network and another computer for their
    network.
    Can anyone tell me if this will work and if it will increase the bandwidth
    on our network.
    Thanks in advance for any help,
    Sher

    Not sure I understand what they're trying to do, exactly. You can run
    two IP networks on the same wire, but that's only if they're on two
    separate networks. In your case, 192.168.1.2 is guaranteed to be on the
    same network as 192.168.1.1, so they're not actually using a different
    network. Maybe you mean 192.168.2.1?

    I'm not sure what you mean by a splitter. Do you mean they actually want
    to split the CAT5 cable to add in an extra drop? If so, I would strongly
    recommend against that. You'd be much better off buying a small switch
    for $50 or so, and adding a patch cable.

    As for adding bandwidth, I can't see any way it would ADD bandwidth to
    your network.

  3. I agree with Grep completely.

    They are on the same network.

    They can't use a Default Gateway just "willy-nilly". A Default Gateway has to
    be either a Routing Device or a NAT Device. If 192.168.1.2 is not any such a
    device then using that address as a gateway is totally meaningless.

    I have never heard of any such splittler and I think they are misleading you
    with either bad terminology or bad ideas or both at the same time.

    I've worked in IT at a TV Station for 7 years. We have Vendors supplying
    software and equipment out the wazzo around here. There is a very important
    number 1 rule:

    #1 Rule
    Never, ever, ever, ever let outside Vendors and outside Companies dictate the
    design of your network. It is their job to make their product work on your
    network by writing it properly,...it is not their job, and should never be their
    job, to redesign your network to fit whatever kind of mess their programmers
    created.

    This #1 Rule of course assumes you have a properly designed network to start
    with.
