We have a Motorola G card that uses the Broadcom chipset. It works as an AP Extreme card.

Because we have other cards set up in the sourceforge WirelessDriver, the airport card is en3. This means that the interface that KisMAC uses is not wlt1, but wlt3.

Run ifconfig, and find the number of the wlt interface, and change the "Capture Interface" to read (in our case) wlt3.
