Spirent TestCenter: Why Wifi clients association could possibly fail after repeated attempts?
It's been found for one particular AP that if the same MAC address re-associates it could take up to 10 minutes before it will allow re-association without failure.
The quantity of clients trying to associate may also play a part in this issue.
A work around is to change the MAC addresses on those devices so that the AP thinks these are new devices.
This is an AP bug and should have the AP vendor investigate it.
