If you are new to networking and have never configured these settings before, we recommend you to leave the
default settings unchanged.

Item Description
Beacon Interval
This is a time interval between any two consecutive Beacon packets sent by an Access
Point to synchronize a wireless network. Specify a valid value between 20 and 999. The
default setting is 100. Generally, the smaller the value is, the faster the client will connect
to the AP; the larger the value is, the faster the wireless data will be transmitted. It is
advisable to leave the default value unchanged.
Fragment
Threshold
Specify a valid Fragment Threshold value between 256 and 2346. The default is 2346. Any
wireless packet exceeding the preset value will be divided into several fragments before
transmission. When the error rate is relatively high, you can lower the fragment threshold.
In this way, if transmission failure occurs, only packets that are not sent successfully needs
re-sending, which will improve the transmission throughput. With no interference, you can
improve the fragment threshold to reduce times to acknowledge frames, also improving the
transmission throughput.
RTS Threshold
The default is 2347. If a packet exceeds the preset value, RTS/CTS scheme will be used to
reduce collisions. Set it to a smaller value provided that there are distant clients and
interference. If the RTS threshold value is relatively small, the wireless access point uses
the Carrier Sense Multiple Access with Collision Detection (CSMA/CD) mechanism, and
the data frame is transmitted immediately after the silence period. The faster the frame is
sent, the faster the wireless network will recover from collisions. As the collision detection
mechanism will occupy some bandwidths, when the packet size is less than the RTS
