WPA-PSK deauthentication (four-way handshake failure)


I have a client that has 10 AP’s and they are connecting and then when they start using the connection it stops. I have gone to the AP’s and when I look at the event logs I can see 1000’s of “WPA-PSK deauthentication (four-way handshake failure)” Errors does anyone know what the cause of this could be?


Sorry no answer here, but just confirming we’re seeing the same issue.
It seems to be a related to certain models. We have a variety, and all are on firmware
The 7600LR and 7610 models are all experiencing this issue. The 7630 models we have are not, but I see that doesn’t match with your situation…
