Hi Murry,
What you need is an SDIO wifi card (i.e. like the Socket SDIO WiFi Card )...Hey, it looks like you could get that from Dell too.
It's about half way down the page:

Do you have a wifi router? You'll need one if you don't. This stuff is so easy to do, you'll be amazed at the simplicity. It literally took me less than 15 minutes to go from unboxing the equipment to surfing!
Let us know how it goes!
