CSCwn21361 is closed - Unreproducible.

@DATHOZ if you believe you can reliably reproduce the issue - and get an over the air packet capture for one or more of the offending packets, then you should open a TAC case and then TAC may re-open the bug if the OTA shows an error in the beacon from the AP.

Also keep in mind that this could just as easily be a bug in the Intel driver so:
- make sure your Intel driver is fully updated
- open a case with Intel as they might know about it already.
