Solution:

The user idle timeout specifies the number of seconds a client can remain idle before the WLC changes the client session to 'Disassociated' state. A client is considered to be idle if it does not send data and does not respond to idle-client probes. You can specify a timeout value from 20 to 86400 seconds.

The default is 180 seconds (3 minutes). To disable the user-idle timeout, set the value to 0.

To change the user-idle timeout, use the following command:

set service-profile <profile-name> user-idle-timeout seconds<1800>

Example configuration:

set service-profile test ssid-name Open_Net set service-profile test ssid-type crypto set service-profile test auth-fallthru last-resort set service-profile test user-idle-timeout 1800 set service-profile test psk-phrase <Password> set service-profile test wpa-ie auth-dot1x disable set service-profile test rsn-ie auth-dot1x disable set service-profile test rsn-ie cipher-ccmp enable set service-profile test rsn-ie enable set service-profile test attr vlan-name test set radio-profile default service-profile test. set ap <ap.no> radio 1 radio-profile default mode enable.
