Optional Wireless Connectivity Solutions: Dell 1370 wireless solution (802.11 b/g) via mini wireless card or Dell 1470 wireless solution (802.11 a/b/g).these are mini pci cards that are installed internaly.
It also has One ExpressCard slot 54mm for an external card.

thanks for your help. i actually ordered the internal, but dell is denying it. i didn't get confirmation of my order, so by the time it got to me, it doesn't make sense to spend shipping back to dell to get it installed.

If you are going to install the card yourself then please take a look at this link.
