remote access of laptop get terminated after few second

By default, the session timeout parameter is configured for 1800 seconds before a authentication occurs.

Change this value to 180 seconds in order to make the client reauthenticate after three minutes.

In order to access the session timeout parameter, click the WLANs menu in the GUI. It displays the list of WLANs configured in the WLC. Click the WLAN to which the client belongs. Go to the Advanced tab and you find Enable Session Timeout parameter. Change the default value to 180, and click Apply for the changes to take effect.

When  sent in an Access-Accept, along with a Termination-Action value of  RADIUS-Request, the Session-Timeout attribute specifies the maximum  number of seconds of service provided before re-authentication. In this  case, the Session-Timeout attribute is used to load the ReAuthPeriod  constant within the Reauthentication Timer state machine of 802.1X.
