Recently I have been trying to set up a wireless network between two routers in the same home, only to realize that only certain routers can connect as clients to other wireless networks.

But now I have my eyes set on something even bigger, I am going to try to set up a network between my house and the houses of two of my friends (all within a 1/4 mile) wirelessly... I have each house set up on its own individual network atm each has a wireless router or 2 inside. What I want to do is to bridge all the networks together wirelessly, hopefully utilizing each of our internet connections to increase bandwidth, and to allow filesharing between the three homes...

Is this possible, if so can someone give me some direction as to what equipment I will need and how to set it up, or maybee some sites that will help me out?
