This tool generates a report for a specific SSID. Enter and SSID, press the "add" button, and then select "run report".
The tool will then query kismet and build a sortable table that groups clients based on: SSID > BSSID.
This data is exportable as PDF and CSV.
You can run multiple SSID's at a time, but be warned it may take awhile if the network(s) have a lot of clients.
