I'm no network geek or owt but I've had my fair share of broadband problems over the last 2 years so hopefully I might be able to help... If you have 2 computers then one pc will act as the host and one as the client. The first plugged directly into the router with an ethernet cable, the second pc should either have a wireless network adapter (if the cable isnt long enough) or will also attach to the router via an ethernet cable and share the internet connection (which will have to be specified when you set the network up in the windows software settings). You will need a modem/router with 2 or more ports (for your 2 computers). Its up to you, you can have the host computer wired to the router and the other pc wireless or you can have them all wireless (as long as you have a wireless adapter attached to each one). Also if your house is anything like mine (if you decide to go wireless) the positioning of your base unit to which the wireless adapter is connected is very important. If I have my computer on the floor it cant get an internet signal, if its on the desk it gets a good signal.
Anyway, I'm gonna stop there cos I'm confusing myself now. Basically sounds like you need a new modem/router with more than one ethernet port and a fuck load of long ethernet wires or a couple of wireless adapters
or some proper advice from a trained internet geek..haaha. Good luck mate, I have less hair than I used to because of this broadband nonesense, hopefully you'll find it easier to sort than I did
