Default setting is set to Activated. If you do not have any 

wireless, both 802.11g and 802.11b, device in your 

network, select Deactived. 

 

Channel 

The range of radio frequencies used by IEEE 802.11b/g 

wireless devices is called a channel. Select a channel 

from the drop-down list box.

The Beacon Interval value indicates the frequency 

interval of the beacon. Enter a value between 20 and 

1000. A beacon is a packet broadcast by the Router to 

synchronize the wireless network. 

Threshold 

The RTS (Request To Send) threshold (number of bytes) 

for enabling RTS/CTS handshake. Data with its frame 

size larger than this value will perform the RTS/CTS 

handshake. Setting this attribute to be larger than the 

maximum MSDU (MAC service data unit) size turns off 

the RTS/CTS handshake. Setting this attribute to zero 

turns on the RTS/CTS handshake Enter a value between 

1500 and 2347.

The threshold (number of bytes) for the fragmentation 

boundary for directed messages. It is the maximum data 

fragment size that can be sent. Enter a value between 

256 and 2346. 

DMIT 

This value, between 1 and 255, indicates the interval of 

the Delivery Traffic Indication Message (DTIM). 

802.11b/g 

The default setting is 802.11b+g (Mixed mode). If you do 

not know or have both 11g and 11b devices in your 

network, then keep the default in mixed mode. From the 

drop-down manual, you can select 802.11g if you have 

only 11g card. If you have only 11b card, then select 

802.11b.
