Yeah, just to confirm, I've never seen a centrino notebook that didn't have a minipci slot. Pretty much every manufacturer lets you swap the intel card for a (a)/b/g card, but if you do that they can't lable it as centrino. So order a truemobile 1400 from dell, or some card that you can confirm works. First off, flip the thing over and find the existing minipci card just to be sure.

What does your wireless card have to do with your VPN software? Don't you connect tot he VPN at the IP layer? I've never used a VPN, so I don't actually know.
