I have extensive experience with this sort of thing on Windows, and what is reported on that platform is the RSSI to the currently associated access point. Given Kismet operates in passive mode, with no associations, where can we guess the figure is coming from?

Contact Atheros in order to find out what and how they have decided to report per packet signal strengths in their various chipsets, then check the madwifi sources for how the driver interprets the data reported by the chipset.

OK, many thanks. It would appear madwifi_g is reporting some degree of packet level information.

Is my assessment that the per-packet signal strength information is not passed to kismet_client correct?
