capability and request.
Encryption: When WPA-PSK or WPA is set as the Authentication Type, you can select
either Automatic, or TKIP or AES as Encryption.

For example: If you desire that the wireless station A with MAC address 00-0A-EB-00-07-8A and the
wireless station B with MAC address 00-0A-EB-00-23-11 are able to access the Router, but all the
other wireless stations cannot access the Router, you can configure the Wireless MAC Address
Filtering list by following these steps:
1.
Click the Enable button to enable this function.
2.
Select the radio button: Deny the stations not specified by any enabled entries in the list to
access for Filtering Rules.
3.
Delete all or disable all entries if there are any entries already.

and
enter
the
MAC
address
00-0A-EB-00-07-8A
/
00-0A-EB-00-23-11
in the MAC Address field, then enter wireless station A/B in the
Description field, while select Enabled in the Status pull-down list. Finally, click the Save and
the Back button.

Beacon Interval: Enter a value between 40-3500 milliseconds. The Beacon Interval value
indicates the frequency interval of the beacon. A beacon is a packet broadcast by the Router
to synchronize the wireless network. The default value is 100.
¾
RTS Threshold: Should you encounter inconsistent data flow, only minor reduction of the
default value 2346 is recommended. If a network packet is smaller than the preset RTS
threshold size, the RTS/CTS mechanism will not be enabled. The Router sends Request to
Send (RTS) frames to a particular receiving station and negotiates the sending of a data
frame. After receiving an RTS, the wireless station responds with a Clear to Send (CTS)
frame to acknowledge the right to begin transmission. In most cases, keep its default value of
2346.
¾
Fragmentation Threshold: This value specifies the maximum size for a packet before data is
fragmented into multiple packets. If you experience a high packet error rate, you may slightly
increase the Fragmentation Threshold. Setting the Fragmentation Threshold too low may
result in poor network performance. Only minor reduction of the default value is
recommended. In most cases, it should remain at its default value of 2346.
¾
DTIM Interval: This value, between 1 and 255, indicates the interval of the Delivery Traffic
Indication Message (DTIM). A DTIM field is a countdown field informing clients of the next
window for listening to broadcast and multicast messages. When the Router has buffered
broadcast or multicast messages for associated clients, it sends the next DTIM with a DTIM
Interval value. Its clients hear the beacons and awaken to receive the broadcast and multicast
messages. The default value is 1.
¾
Enable WMM - WMM function can guarantee the packets with high- priority messages being
transmitted preferentially. It is strongly recommended enabled.
¾
Enable Short GI - This function is recommended for it will increase the data capacity by
reducing the guard interval time.
