Known Affected Releases

8.10(128.114)

Description (partial)

Symptom:
Radio keeps on crashing every time a Intel AX200 client tries to join the SSID and hence it is impossible for the client to join. Other 11ax clients like a android phone join properly.

Conditions:
9117 Access Point running the 8.10.128.114 EFT code.
Disabled the 11ac MUMIMO and 11ax MIMO and OFDMA on the WLC.
AP crashed once after disabling the above config for the first time but subsequent enabling/disabling did not crash it.
Affecting only Intel AX200 clients.
SSID is simple WPA-PSK.
