PSK SSID - Unable to connect

[lazuardinurfaiz]

I am using Cisco Wireless Controller 3504 running 8.10.112.0. I use this WLC for two site, both of them running flexconnect mode. On 1 site, I have a SSID using PSK as security. Recently, some endpoint (android smartphone) cannot connect to that SSID.

Can you help me to solve this issue?

Thank you.

Hi Sandeep.

I attached the output of show_wlan_id. I try to debug_client with the affected mac address, but no log is shown.

There is another workaround to disable SHA1 and only use WPA2-SHA256 with FT disabled.

Can you share the device models affected by the issue? It all appears to be an issue related to latest Qualcomm chipsets' firmware with Cisco's IE att 44.

Thank you! After enabling FT on WLAN, all android 10 are able to connect.
