Dude, like dan said, so easy. Get a wifi router, plug your dsl into it, and then connect any computers with either a wire or a wireless pci card (or usb like dan said). DHCP does all the rest.

is the router in that link ok? what are good network cards to get?

that router looks fine. you could try looking for some reviews if you feel like it. I read through the manual real quick, and it will support your verizon dsl no problem. as far as pci cards, i'...

right, but I would need one for the other computer
