wireless network. If your 802.11g Wireless LAN PC
Card often transmit large files in wireless network,
you can enter new Fragment Threshold value to split
the packet. The value can be set from 256 to 2346.
The default value is 2346.
RTS Threshold RTS Threshold is a mechanism implemented to
prevent the “Hidden Node” problem. “Hidden Node” is
a situation in which two stations are within range of the
same Access Point, but are not within range of each
other. Therefore, they are hidden nodes for each other.
When a station starts data transmission with the
Access Point, it might not notice that the other station
is already using the wireless medium. When these two
stations send data at the same time, they might collide
when arriving simultaneously at the Access Point. The
collision will most certainly result in a loss of messages
for both stations.
Thus, the RTS Threshold mechanism provides a
solution to prevent data collisions. When you enable
RTS Threshold on a suspect “hidden station”, this
station and its Access Point will use a Request to Send
(RTS). The station will send an RTS to the Access
Point, informing that it is going to transmit the data.
Upon receipt, the Access Point will respond with a CTS
message to all station within its range to notify all other
stations to defer transmission. It will also confirm the
requestor station that the Access Point has reserved it
for the time-frame of the requested transmission.
If the “Hidden Node” problem is an issue, please
specify the packet size. The RTS mechanism will be
activated if the data size exceeds the value you set..
The default value is 2347.
Warning: Enabling RTS Threshold will cause
redundant network overhead that could negatively
affect the throughput performance instead of
providing a remedy.
This value should remain at its default setting of 2347.
Should you encounter inconsistent data flow, only minor
modifications of this value are recommended.
Beacon Interval Beacon Interval is the amount of time between beacon
transmissions. Before a station enters power save
mode, the station needs the beacon interval to know
when to wake up to receive the beacon (and learn
