Specify the settings as explained in the following table:

Click Apply to save your settings.

Beacon Interval

Enter an interval between 40 ms and 3500 ms for each beacon transmission, 
which allows the wireless VPN firewall to synchronize the wireless network. The 
default setting is 100.

DTIM Interval

Enter the Delivery Traffic Indication Message (DTIM) interval, also referred to 
as the data beacon rate, which indicates the period for the beacon DTIM in 
multiples of beacon intervals. This value needs to be between 1 and 255. The 
default setting is 2.

RTS Threshold

Enter the Request to Send (RTS) threshold. The default setting is 2346 bytes.

If the packet size is equal to or less than the RTS threshold, the wireless VPN 
firewall uses the Carrier Sense Multiple Access with Collision Detection 
(CSMA/CD) mechanism, and the data frame is transmitted immediately after 
the silence period.

If the packet size is larger than the RTS threshold, the wireless VPN firewall 
uses the CSMA with Collision Avoidance (CSMA/CA) mechanism. In this 
situation, the transmitting station sends an RTS packet to the receiving station 
and waits for the receiving station to return a Clear to Send (CTS) packet before 
sending the actual packet data. This method improves the performance but 
reduces the throughput.

Fragmentation Threshold

Enter the maximum packet size that is used for the fragmentation of data 
packets. Packets that are larger than the specified fragmentation length are 
broken up into smaller packets before being transmitted. The fragmentation 
threshold needs to be an even number. The default setting is 2346 bytes.

Preamble Mode

Specify the preamble mode by making a selection from the drop-down list:

• Long. A long transmit preamble might provide a more reliable connection or 

a slightly longer range. This is the default mode.

•  Short. A short transmit preamble gives better performance.

Protection Mode

Specify the Clear to Send (CTS)-to-self protection mode by making a selection 
from the drop-down list:

•  None. CTS-to-self protection mode is disabled. This is the default mode. 

• CTS-to-Self-Protection. CTS-to-self protection mode is enabled. This mode 

increases the performance but reduces the throughput slightly.

Power Save Enable

To enable the Wi-Fi Multimedia (WMM) Powersave feature, select the Power 
Save Enable check box. This feature saves power for battery-powered 
equipment by increasing the efficiency and flexibility of data transmission. Clear 
the check box to disable the feature, which is the default setting.
