I think you can just purchase one wireless router and one access point to set up your network. Check out this detailed tutorial on how to set up wireless network: http://www.home-network-help.com/wireless-network.html
Hope this helps.. :o)
I want to network 2 homes for internet access and Voip in both homes from 1 cable modem. The homes are diagnal from each other and the computers will be on facing walls about 100' from each other, max. I am looking at MIMO because of the aluminum shell of both mobile homes. Can I just have 2 routers, one in each home, and WAN by wireless or do I need something else? I don't want to have to run a wire between the homes. Thanks.
