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.

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.
