Networking two routers

You have two internet connections in the same house? If so, just hooking the two routers together would eliminate one of the net connections. If you can afford the loss of bandwidth, (and the bill for it) then that would work. If you need the bandwidth, and can afford it, I would recommend getting a HotBrick: http://www.hotbrick.com/produto.as [...] 2&codPro=1
There may be some configuration issues with the VOIP you will need to resolve, but should work.

You'll want to assign static IP addresses to either ALL computers or only assign static IPs to computers that are to use a specific ISP.
Basically, I think you would be better off assigning static IP addresses to all computers so you know where each will be going. Disable DHCP on both routers.

Example:

Router 1:
IP: 192.168.1.1
Using ISP #1

Router 2:
IP: 192.168.1.2
Using ISP #2

Computer #1 wants to use ISP#1
IP: 192.168.1.100
Gateway: 192.168.1.1

Computer #2 wants to use ISP#2
IP: 192.168.1.101
Gateway: 192.168.1.2

You can create your own IP scheme: 192.168.1.1-9 is for ISP #1, 192.168.1.20-29 for ISP#2, etc.

If you need help setting a static IP address, post back and we can help out.

Ok basically I used Riser's configuration... had me confused for a bit on the IP addresses of the computers themselves but I figured out what he meant to say.

Only problem I ran into was we actually had another router (the voip box) connected to router 1 and caused the computer and phone connected to it to not function properly.

So basically what we did is bought a 50ft phone line and ran it to the other room and eliminated one of the routers without VOIP. Now everything works like a charm, internet & lan.

Thanks for the help guys, I always hated networking because there seemed to be no straight working answers to simple questions
