Does it occur often on in special situations? Can you place the complete logfile? If you are notr sure when it has happend install an NTP Server like JANA Server at this way the correct time is mentioned in the AP, also in the logfile.

J_Bell Posts: 5822 Rating: (412)	Dear King kong, might it be that the Client module is set to use the function "Auto find Adopt MAC" Address? If so please read the chapter 5.7.4.3 in the Manual, it shows that this function should not be used if you have several Nodes connected to the Wireless Client module. This would be the only reason I could imagine to be the cause of the problem as it shows it right here. Best regards J_Bell

MaPentti Posts: 3 Rating: (0)	Sorry for bringing this old topic up, but could not find a newer one. We faced the same message for a couple of times and always the authorized client disconnects. In our setup we have only one client (w746-1pro) for each AP (w788-1pro). Each AP have different SSIDs. I found these two articles: http://www.willhackforsushi.com/papers/wlan-sess-cont.pdf http://www.defcon.org/images/defcon-16/dc16-presentations/defcon-16-ahmad.pdf Quote: """ It is well known that by sending spoofed De-authentication or Disassociation packets it is possible to break AP to client connections. A De-authentication packet spoofed with source address = AP MAC address causes disconnection in client’s state machine. Likewise, a De-authentication packet spoofed with source address = Client MAC address causes disconnection in AP’s state machine. """

If yes please tell us more about your setup, maybe a small drawing and als mention the channels from the AP's. If possible also add the configuration files in aa ZIP-file. You could send them password encrypted and send the people who waant it the password for the ZIP-file via private message. Also add the logtables of both AP's and Clients.
	Best regards, INS
