As Woodchip says; use the router in place of your existing BB modem. Stick the card into the slot on the side of the laptop. I expect there will be a disk to configure the new set-up (there was with my router, etc.0
OOps, Woodchip - we've both mised the fact that DP7 wants to connect 2 desktops. Basically the same process, but I can't recall which bit of kit you need for the 2nd desktop. Someone else will point you in the right direction.
OK. YOU need as router as Woodchip mentioned and 2 PCI adapters - one goes in each PC. But you don't want the PCIA card (as used in a laptop)so you shouldn't buy the exact package that woodchip referred to. someone will no doubt provide a link to a package for 2 desktops. It's an easy job to deal with once you've bought the kit.
And if on two floors you need at least one Computer to connect by means of Ethernet Cable to setup the Router, so if you do not have Ethernet port on computer you will need a card, you will also need a wireless card if it's a Desktop, If a Laptop the free card with the above router is wireless
