Users disconnect continuously

[UsmanAkram1525]

Hi, we are using a virtual Cisco wireless controller: software version, 8.3.141.0 with basic configuration. but our users facing the issue of disconnection and mostly are Apple Iphones

1. simple SSIDs with WPA2, AUTH PSK
2. All Access points configured on Flex-Connect mode
3. No VLAN and AP Model is: AIR-CAP1602I-A-K9

Please advise, Thanks!

First I would recommand to upgarde the software to stable version: https://software.cisco.com/download/home/284464214/type/280926587/release/8.3.150.0

8.0.140.0 version is alredy deferred from cisco.

If enabled, disable 802.11r (FT) for testing. Do you use Client Load-Balancing? That can also cause this.
