Update Period
Specify an update period of the encryption key. The update period instructs 
how often the EAP should change the encryption key. 0 means that the 
encryption key does not change at anytime.
Cofigure Wireless Advanced Settings
Configure the advanced wireless parameters of the EAP and click Save.
The following table introduces how to configure each item:
Beacon Interval Beacons are transmitted periodically by the EAP device to announce the 
presence of a wireless network for the clients. Beacon Interval determines 
the time interval of the beacons sent by the EAP device.
You can specify a value between 40 and 100ms. The default is 100ms.
DTIM Period The DTIM (Delivery Traffic Indication Message) is contained in some 
Beacon frames. It indicates whether the EAP device has buffered data for 
client devices. The DTIM Period indicates how often the clients served 
by this EAP device should check for buffered data still on the EAP device 
awaiting pickup.
You can specify the value between 1-255 Beacon Intervals. The default 
value is 1, indicating that clients check for buffered data at every beacon. 
An excessive DTIM interval may reduce the performance of multicast 
applications, so we recommend you keep the default value.
