The type of Router you require depends whether your broadband is Virgin's
Cable service or
ADSL via the phone line. Cable uses a stand-alone Router in conjunction with the Cable Modem supplied by Virgin; ADSL requires a combined "Router & ADSL Modem" to replace a USB Modem.

When both computers are connected to the Router, they are "Networked" and you will be able to "Share" folders in either computer and the Printer attached to the Desktop PC. In order to print from the Laptop via the printer attached to the Desktop PC, the Desktop PC will have to be running. I have posted instructions for setting up a "Network" printer in XP or Vista
