Okay...now that I have the cable internet, what's the best buy on wireless networking equipment?
Look around. Sometimes you can get one for $40 in the stores. Some of my friends who buy from bargain sites online have found them for $30 or so. - That's for the router. The network cards are actually more expensive. But the ones that attach to usb slots rather than network adapter spots are usually cheaper.
I'd go for stuff that's compliant with the 801.11G standard rather than just the .11B standard
