Hi Jason, Thanks a lot for the info. I've already set the User Idle Timeout to further prolong the connection of the client to the network. Yes you are correct normally a 1 client could have at least 3 devices connected to a network (laptop, smartphone and tablet) and this could really increase the max out of the client on the WLC. Bigger Problem! We will monitor our new setup and also inform the users about this.

Technically, the User Idle Timeout applies to all users. So, by default, if a MAC address doesn't send traffic for 300 seconds, that device is removed from the Client list and would require a reauthentication when reconnecting. You can increase that timeout to try to cover the scenario you are describing. There are 2 things to keep in mind eith this. The longer the timeout value, the more clients are held in the list. So, you increase the risk that you will max out on clients for the WLC. Second, iPads (and possibly iPhones) send an active deauthentication when they go to sleep or hibernate. So, they will be removed. As Oliver said, there is also the WLAN Session timeout, which requires a reauthentication at the timeout value. So, adjust that value to also be greater than the expected time that the clients will not be on the network. This value is for all authentication types, but Open simply continues as is, while PSK will negotiate a new PTK at that time (without client intervention.)

Open/PSK - User Idle Timeout - (Contoller>General). Default is 5min 2. EAP - Session Timeout - (WLAN>Advanced). Default it 30min. In this case the shorter of two takes presedence. Aditionally if adding guest user on the WLC verify Guest Account timeout, or specific EAP timer on the AAA server.

Scenario: Using smartphone, customer already connected to the network. After going out for a while and leave the network user will be again asked to re-insert his username and password. Do we have a way to make the smartphone reconnect to the network without the authentication again like a normal laptop? Tried several times with iphones, samsung and blackberry with NO luck. Tried to check the controller if we can tweak. _______________________________________________ For more information regarding industry leading CCIE Lab training, please visit www.ipexpert.com<http://www.ipexpert.com> Are you a CCNP or CCIE and looking for a job?
