Ap7532 some android clients alternately failed to receive ip addresses

[Aviv_Kedem]

Hello community, I have an issue with Ap7532 some android clients alternately failed to receive ip addresses, but they are authenticated successfuly. Seems there is some issue with receiving ip. There is any recommendation? I think there is something generic. Configured with wpa2 psk, trunk on ge1. Thanks, Aviv
