Bridging two Wireless Routers
Got this post of our internal mailing lists... good information on connecting two wireless routers together to get networking to a part of your house you currently don't have any wiring for... or into a neighbors house.
I have my setup like this:
cable mode <-ethernet-> Router 1<--wireless--> Router 2
Router 1 connected to my VOIP phone adapter and my Home PC.
Router 2 connected to my Linux box (mostly used for my MythTV).
Router 1 and Router 2 talk to each other wirelessly (they both acts as wireless bridge).
Both also act as Access Point but only Router 1 acts as gateway and DHCP server. So anything connected to Router 2 still gets IP from Router 1.
If you have linksys WRT54G or Belkin F5D7230-4 you can do this setup but I'm not sure if you can do with other brand routers.
