How to home networking computers with only a dial-in modem?

Sher: How to home networking computers with only a dial-in modem?
I know how wireless network work with cable and DSL. I am still keen on keeping my dial-in connection while networking all our computers (4) and printers (2) so that files and printers can be shared from different computers in the different rooms. The wireless routers and adapters seemed to serve cable/DSL connections. Any ideas how mine would work?

There is nothing that says you can not network at home without a broadband internet connection. Just buy the router and Nics that you require and away you go! Just do not connect anything to the WAN port of the router.
