I have two computers in my room. I have a DSL Modem and a Linksys router connected to it. Both computers are connected to the router with ethernet cable. How can I make these computers into a network station (connected). So I can play LAN games with it.?

I saw the microsoft site where it teaches you, but it didn't helped me a lot. I also cannot get help from the Network forum so i post this here. Thank you
