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 whether there are
buffered frames at the access point).
Data Rate
By default, the unit adaptively selects the highest possible rate for
transmission. Select the basic rates to be used among the following options:
Auto, 1, 2, 5.5, 11or 54 Mbps. For most networks the default setting is Auto
which is the best choice. When Auto is enabled the transmission rate will
select the optimal rate. If obstacles or interference are present, the system will
