I'm encountering folk that think because a card, stick plugs in it should work. Sorry, stick to what Dell lists on their site as what works. Also some expect email replies but I find the PHONE and pleasantries to work along with payment for support (modest usually less than 100 bucks) is the answer.

But what are you trying to do here. You had wifi at least. Are you trying to add N or blue tooth? If so I find PC-Cards and USB dongles to be the answer.
