Beacon Interval: 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 AP
to synchronize the wireless network. The default value is 100.
DTIM Interval: This value 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 AP 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.
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.
RTS /CTS Threshold: Using this setting can regulate your wireless network if you
experience any inconsistent data flow situation, only by minor adjustment of the
default value, the default value 2346 is recommended. The RTS/CTS mechanism will
not be enabled if your wireless network packet less than RTS threshold value. The AP
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. The RTS
Threshold value should keep at its default value of 2346.
Short Preamble: This setting is for 11b clients, usually set short value will enhance your
WLAN performance for 11b client, however the 11b clients must have same feature as
well.
Allow 2.4GHz 54Mbps Station Only: In order to keep high performance for this WLAN,
set this option Enable will only allow stations with 54Mbps data rate to associate this
AP.
RTS/CTS Protection Mode: CTS (Clear-To-Send) Protection Mode should be set to
Auto (Default). The AP will automatically use CTS Protection Mode when the
Wireless-G products are experiencing severe problems and are not able to transmit to
the AP in an environment with heavy 802.11b traffic. This function boosts the AP’s
ability to catch all Wireless-G transmissions but will severely decrease the
performance. If you do not want to use CTS Protection Mode at all, select Disabled.
