 Fragmentation Threshold: Packets that are larger than this threshold are
fragmented into multiple packets. Try to increase the fragmentation
threshold if you encounter high packet error rates. Do not set the threshold
too low, since this can result in reduced networking performance.
 RTS Threshold: This value should remain at its default setting of
2347.Should you encounter inconsistent data flow, only minor reductions are
recommended. Should you encounter inconsistent data flow, only minor
reduction of the default value, 2347, 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. The RTS Threshold
value should remain at its default value of 2347.
 DTIM Interval: (Delivery Traffic Indication Message) Enter a value between
1 and 255 for the Delivery Traffic Indication Message (DTIM.) A DTIM is a
countdown informing clients of the next window for listening to broadcast
and multicast messages.
 Beacon Interval: A beacon is a packet of information that is sent from a
connected device to all other devices where it announces its availability and
readiness. A beacon interval is a period of time (sent with the beacon) before
sending the beacon again. The beacon interval may be adjusted in
milliseconds (ms). Default (100) is recommended.
 XPress Technology: Select Enable or Disable. This is a special
accelerating technology for IEEE802.11g. The defaule is Disabled.
 Transmit Power: Adjust the transmission range here. This tool can be
helpful for security purposes if you wish to limit the transmission range.
 WMM (Wi-Fi Multimedia): Select whether WMM is enable or disabled.
Before you disable WMM, you should understand that all QoS queues or
traffic classes relate to wireless do not take effects.
 WMM No Acknowledgement: Select whether ACK in WMM packet. By
default, the 'Ack Policy' for each access category is set to Disable, meaning
that an acknowledge packet is returned for every packet received. This
provides a more reliable transmission but increases traffic load, which
decreases performance. To disable the acknowledgement can be useful for
Voice, for example, where speed of transmission is important and packet
loss is tolerable to a certain degree.
 WMM APSD: APSD is short for automatic power save delivery, Selecting
enable will make it has very low power consumption. WMM Power Save is
an improvement to the 802.11e amendment adding advanced power
management functionality to WMM.
