WPA Decrypt Errors

Unanswered Question

I just upgraded one of my WLC's to 4.1.185 and now my log gets filled with WPA decrypt errors. They seem to coincide with the WLAN timeout or the user idle timeout. I don't know if users are noticing problems. What's up with this? Also, I'd like a good explanation of the WLAN/Idle/ARP timeouts and recommended values.

Driver error on client side is the most common cause. Idle timeout refers amount of time user be timedout after remaining IDLE . This is 300 sec by default. WLAN is the amount of time after whcih clients in a particular WLAN are made to reauthenticate. Default is 1800 seconds. There is no recommneded value. It sdepends on the network.
