Out of all of these stations associated which station (or stations) is chewing up the most RF time. horst can show you some of this but its per packet and modulation and not per station. I've been in contact with the author to see about adding stats per station but he says it's a pretty big effort. What I'm most likely going to do is use it's output feature to generate a log and then post process that in python where I can easily aggregate things on a per MAC address. -- Richard A. Smith
