PSK SSID - Unable to connect

lazuardinurfaiz — Mon, 05 Jul 2021 19:06:30 GMT

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.

Best regards,

Are those unable-to-connect devices using Android 10?

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.

Best regards,

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.
