Of course you do! I thought you knew atleast that much. If you buy a wireless nic or usb adapter, yoiu will of course need a wireless router. Otherwise, if you don't want to go w/ the wireless option, just buy a standard DSL/Cable router.
Incidentally, I saw a nice deal at MicroCenter last nite where they have a Belkin 4 port DSL/Cable router on sale for only $10 after rebates. Normally $50.
EDIT: In your situation since the pc connected via modem is located downstairs; it might be a good idea to go with the wireless option since you don't have to worry about running the cat5 cabling all over the house. This will mean that all the others PCs/ Laptops in your house will need a wireless NIC/adapter as well.
