7920 authentication failed

I got Cisco Wifi Controller with 1300 Access Points working with TACACS+.

We have 7920 and 7921 wifi phones. Initiallty, everything worked fine, but today I noticed that 7920 phone do not authenticate. I looked through Controllers logs and found this:

Could not process the RSN and WARP IEs. station not using RSN (WPA2) on WLAN requiring RSN.

However, 7921 work fine.

What is the problem?

7920 does not support WPA2 or AES encryption.

If you want to mandate WPA2 for the 7921s, where fast roaming (CCKM) will then not be an option, then configure a separate SSID for the 7920s to use WPA(TKIP)+CCKM.

I does support WPA2, I configured it to use AKM authentication mode, now it is ok

No that is incorrect. The 7920 does not support WPA2, but 7921 does.

Yes must use AKM on the 7920 when using authenticated key management (CCKM, WPA, WPA-PSK). For 7921, use AKM for WPA-PSK, but choose the EAP type when doing CCKM, WPA or WPA2.

Thank you
