I am running Cisco 5520 Wireless Controller.
The AP model is AIR-AP1852I-Q-K9 , The IOS version is 8.8.130.0
There are 2 SSIDs configured
SSID#1 : INTRA_WIFI - For Internal Wireless LAN network : Uses certificate authentication
SSID#2 : GUESTWIFI - For guest Internet access : Uses username & password authentication : PSK (WAP2/WAP3 personal)
There are nearly 50 APs. We rebooted all the APs as part of maintenance.
After the APs are rebooted,
1. Users using iPhone/ipad are not able to connected to GUESTWIFI (Users got password incorrect msg)
2. Laptop users are able to connect to GUESTWIFI
3. Laptop Users are able to connect to INTRA_WIFI (iPhone users are not allowed to connected to INTRA_WIFI)
1. Users using iPhone/ipad are not able to connected to GUESTWIFI (Users got password incorrect msg)
Eventhough the password is correct users are not able to login via iPhone/ipad
We again rebooted all the APs & after that the users are not facing the same issue. The issue got resolved.
Is there any reason for this to happen? Below are some of the logs which I found in the WLC.
