Different Subnets

[Guest]

Hello,

I have been requested to install a second wireless router at a clients and
put on a different subnet. The ip address of current network is 10.1.1.x with
the router set to 10.1.1.1. Do I need to out this second router on a similar
subnet mask of 255.0.0.0 for a 10.x.x.x ip address?

I tested at our office where we have a wireless router setup with a
192.168.16.1 ip address and I left the second wireless router with its
default settings of 192.168.1.1.

This worked fine for what I was trying to achieve i.e. have users on the
second subnet access the internet and share files etc without having access
to the first subnet of 192.168.16.x

However, when I changed the second wireless router address to 10.1.2.1 at
our office (our first subnet is 192.168.16.x), the router did not allow me to
do this. I thought that the whole point of routers was to create separate
subnets thus separating networks!

Basically, I wanted to get everything ready before getting to the clients.
It looks like I will have to setup the second router at the clients to
correspond to the ip addressing scheme they already have whilst onsite.

Any guidance really appreciated,
Jeff

Most cheap consumer routers only work with class c addresses. You may be
able to use 10.1.2.1/24. I'm betting you have to stick with 192.168.x.x/24
or possibly even 192.168.1.x/24. If you have less than 253 wireless clients
this shouldn't be a problem. If you have more than a dozen or so wireless
clients you need to be looking at a better router anyway.

Kerry, many thanks for your prompt reply.

There will be 9 laptop users in this classroom from time to time. Additional
users may come in or may not.

Anyhow, so you are saying that as the clients network is on a 10.x.x.x
addressing scheme, I have the opportunity to hook up the second router with a
192.168.1.x addressing scheme. The second router will still need to connect
to the internet even through it will probably get a 10.x.x.x WAN address from
the first router but be configured on the LAN side with 192.168.1.x. This
will work?

Many thanks,
Jeff

Yes it should. There is a potential security risk of computers on the
192.168.1.x subnet accessing computers on the 10.x.x.x subnet.

ok, thanks Kerry, i'll give that a go.
