I would recommend that you buy a Linksys etherfast Dsl/cable router hub combo, it runs about 150 dollars US and will work as both a hub for your home Lan and a router for your internet connection, it also acts as a DHCP server so you only need to purchase one IP address and then the hub will create Dynamic IP's to assign to your computer, it is very simple to set up, your ADSL modem will run into the Hub in the uplink port and then your 2 PC's into the LAN Jacks, then all you have to do is tell it all the DSL info, IP address, subnet, and all that. The hub was specifically designed to share a DSL or cable modem connection so it comes with all the instructions on how to do it, I think you can order them online from outpost.com for about $140 last time I checked, best price I've seen on them.
