i am just wondering if it is possible to connect a router to another router. the setup i would like to do is this:

I have a Modem that is my internet connection i would like to attach two computer to it and also run another lead to a seperate router and connect two computers off of it.

Yes, you'd disable DHCP in the second router and hook the second router to a regular input on the first router instead of the INTERNET connector.

In essence, you are treating it like an expensive switch

Why are you adding this second router? Are you doing it for security purposes or to achieve additional port density at another location?

I'm assuming that the other two computers are a bit further away, and by just running one ethernet cable to the second router, the second computer can be further away without having to get an extra long cable

Nothing that couldn't be accomplished with a cheap switch.

Connecting two (or more) SOHO broadband routers together.

Note: The "primary" router can be an actual router, a software gateway like Microsoft Internet Connection Sharing, or a server connection that has the capability to supply more than one IP address using DHCP server capability. No changes are made to the primary "router" configuration.

Configure the IP address of the secondary router(s) to be in the same subnet as the primary router, but out of the range of the DHCP server in the primary router. For instance DHCP server addresses 192.168.0.2 through 192.168.0.100, I'd assign the secondary router 192.168.0.254 as it's IP address, 192.168.0.253 for another router, etc.

Note: Do this first, as you will have to reboot the computer to connect to the router again for the remaining changes.

Disable the DHCP server in the secondary router.

Setup the wireless section just the way you would if it was the primary router, channels, encryption, etc.

Connect from the primary router's LAN port to one of the LAN ports on the secondary router. If there is no uplink port and neither of the routers have auto-sensing ports, use a cross-over cable. Leave the WAN port unconnected!

This procedure bypasses the routing function (NAT layer) and configures the router as a switch (or wireless access point for wireless routers).

JW, I mean to keep copying that

I originally had a wired router at one end of the house for one computer. I went in the attic and ran a 75 foot Cat5 cable to the other end of the house when I got a second computer. When my kids got computers I added the wireless router because I did not want to ever go into the attic again. Looks like this.

Neat, my text solution in graphical form!
