What does the "Deauthenticate" menu do?

Deauthentication packets are sent from access points in order to tell clients that they are no longer are no longer available for service. KisMAC offers a feature to spoof these packets and therefore effectively disturb any communication on the accesspoint. To increse the efficiency of the program, you should disable channel hopping.
This is a very effective way to reveal SSIDs of hidden networks, as well as generate more traffic for detection of weak IVs.

Note: Some access points might recoginze this attack and switch channels.
