Right, networking was one of those things I never figured I'd need to learn about. But now the time has come, I purchases a ThinkPad but it wasnt the model with the combo card (which wouldnt let me be mobile anyway), and so right now I need to get a Router and a Pcmcia wireless card. But I am quite the cheap little man, and want to get the best deal. So what I need to know is whats the bare minimum I should be looking for in a router/wireless card.

For the router it doesnt need to be wireless since I have pretty lengthy CAT-5 cables that are working fine for now (modem in living room, this computer in room). So what could I go cheap on. However a guy from Ebay lives in my city and is selling this -

Good deal for 20 bucks?

As far as wireless cards, again what am I looking for? I see wireless cards that are strictly for sharing internet, but then others that offer to share other networking things like shared HD space, etc. Heres one I'm looking at from FRY's (big computer chain)
