Integrity check failure in encrypted message

Hi,

my customer gots this error message with some users:

MIC.PNG

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

Recommend checking the encryption setting on the client and on the AP.

 

do any one have an idea about this issue

Re: Integrity check failure in encrypted message

Two biggest reasons for this:

 

1.  Client driver needs to be updated

2. Contention and interference

3.  Clients are being hacked (much less likely)

 

What is the utilization and noise on that access point for the band that those clients are on?
