Yeah, I've got the Ambicom card too. I was trying to decide between them all since they're basically all the same. CompUSA had it for 60 - 30 mail in rebate = 30 bucks... Can't beat that, and I couldn't be happier. Just a suggestion for you cparks, if you use several different access points, this could be a very handy utility for you.

I use it all the time, I never have to configure anything manually when associating with different wireless networks...
