How do you connect two computers without Internet to play games on a LAN etc if they are running Windows Vista and if you have a Linksys router

You have to have: 1 home computer that you don't turn off much, a wireless router, and another computer to connect with. Plug in the router to the "server" computer and go to Network and Sharing center. Setup wireless network WITHOUT internet connection. Both computers have to be in the same Workgroup.
