D-Link seems to have the best routers on the market for home use. I use a motorola, cause it was given to me for christmas. Not my first choice, but so far it's been good enough. They are also working on new firmware for the router which should provide more options. Although there are alot of options now. WR850G is what I have and I actually recommened it, since you can get it cheap!
A wireless PCMCIA card will also be needed. 802.11G is the standard you will want to buy. You can walk away 50 bucks for card and another 10 (after rebates) to 100 for a decent router. Just stay away from belkin.
