Setting up network\router

[Mongoose]

Ok, I'm totally confused right now. Me and my flat mates are trying to share our internet connection, but we can't figure out how to do it.

We've got a wireless\wired router and an ADSL router. So far we've got the ADSL router plugged into the phone line, and an ethernet cable running from the ADSL Router to the 'internet port' on the other router. The other router is also connected to the other computers, which we hope will be able to access the internet.

So far, I'm pretty sure that's right. The problem is that none of the computers can access the internet. The ADSL Router has an active connection (that's how I'm online now, but I'm running it straight through my computer as opposed to the other router).

How can I sort this out? I'm with Virgin Broadband.
Thanks

What IP address ranges are handed out by the two routers?

I haven't tried this sort of setup before but I'm wondering if ADSL router has handed out an IP address (say 192.168.1.2) to the Wireless router - and that is confusing things because it has 192.168.1.2 as it's external IP and has also handed out 192.168.1.2 to one of the PCs connected to it. The router would then most likely be directing all internet requests to which ever poor machine has that IP as it's the same subnet.

IF it's going to work, as brundles says you will need to ensure the two routers are on different IP subnets. Don't know what the defaults are on these boxes, but I would suggest setting the BT device to use an internal address range 192.168.1.xxx with a 255.255.255.0 subnet mask. The second router should have an internal address range 192.168.2.xxx with same mask.
eg
BT internal IP - 192.168.1.1
Generic 'external IP' (supplied by BT rtr) - 192.168.1.100
Generic internal IP - 192.168.2.1
PC IP address - 192.168.2.100
That should allow IP traffic to be routed from PC to router to BT router to internet.
This of course assumes the generic router will work connected to another router.

Thanks guys, you're total legends!
All seems to be working now, if a little slow. Thanks alot for the help!

I put in a similar setup in a local Hotel so that guests would be able to access the Internet without direct access to the Hotel office PCs.

And it works really well.
