IAP dhcp request timed out and integrity check

Hi

 

For some time ago we received a lots of "DHCP request timed out" but since most of the clients could connect to the wireless we let it go. Now i started to see that clients are gettting "Integrity check failure in encrypted message". 

Ive read that a lot of people are having trouble with the DHCP request timing out and now with the combination of the integrity check failure im wondering what the problem can be?

We are running 6.1.3.1-3.0.0.1_33617

 

Thanks

Re: IAP dhcp request timed out and integrity check

Support says the following :

 ##########################

100410
    

Integrity check failure in encrypted message
    

The IAP cannot receive data from this client because the integrity check of the received message (MIC) has failed.
    

Check the encryption setting on the client and on the IAP.

###########################

What do you see in the IAP logs, any errors? Do you have enough free IP's in the DHCP pool? If you could provide the DHCP logs we can take a look at these :)
