i want to set up a connection between my pc, and the one down the hall that the rest of my family uses. this pc has a broadband connection to the net, which i want the other pc to be able to share the connection. i also want to be able to take files from that pc, and put files on it from my machine. what equiptment will i need, any guides to setting it up? any links to suggested products? i want to keep this as low costing as possible. any questions you may have on my vaugeness, ask away. thanks.
