This doesn't actually make sense - it shouldn't matter, and I definitely haven't seen this behavior. I *only* run Kismet on cards that don't connect to networks.

The first thing Kismet does is make a monitor mode vap, and then (assuming you're running a modern kismet version) shuts down the managed mode vap; it won't get along very well WITH a connected card, infact.

What card/drivers/kismet versions?
