Hi all,
I have a strange problem where Cisco Aironet 1702i will connect wireless RADIUS clients on 5GHz radio interface but not on 2.4GHz radio interface. This AP is running in Autonomous mode. RADIUS/EAP clients were initially able to connect to the 2.4 GHz interface but some time (a month) after deployment all RADIUS clients which are attempting to connect to the 2.4 GHz interface are unable to connect. There were no changes done on AP or the RADIUS server.
Here is IOS version that is running on this AP:
Cisco IOS Software, c1700 Software (AP3G2-K9W7-M), Version 15.3(3)JAB, RELEASE SOFTWARE (fc1)
Here is my AP config:
aaa new-model

aaa authentication login default group radius local
aaa authentication login eap_methods group radius
aaa authorization exec default group radius if-authenticated
aaa accounting delay-start
aaa accounting exec default start-stop group radius

Non EAP clients can connect to the 2.4GHz interface on Typhoon_2 SSID without issues.

Figured it out myself.
Basically I have removed Typhoon_2 SSID and Both Tsunami SSIDs started to authenticate against the RADIUS just fine. Sounds like you can't have 2 SSIDs on the same RADIO interface unless you use MBSSID but with Cisco autonomous APs you can't use MBSSID...
