Configure Wireless Advanced Setting

To achieve optimal wireless performance, it is necessary to tweak advance setting per
requirements properly, not necessary higher the better or lower.
The administrator can change the RTS threshold and fragmentation threshold settings
for the system. Please click on Wireless -> Advanced Setup and follow the below setting.
Fragment Threshold : The Fragment Threshold is in the range of 256~2346 byte.

The default is 2346 byte.
Each Wi-Fi packet can be divided into smaller packets, marked with a sequential
fragment number and re-assemble in the receiving ends. The purpose is to make a
short frame, instead of long frame, transmitting by radio in a heavy noisy
environment. Because of sending smaller frames, corruptions are much less likely
to occur. The pros is obvious, the cons is the overhead for transmission. So, in a
clean environment, higher fragment threshold can be an option to increase
throughput.
Fragmentation will be triggered by setting the Fragment Threshold, usually in Byte-
length. Only when the frame size is over the Threshold, fragmentation will take
place automatically.
RTS Threshold : RTS Threshold is in the range of 1~2347 byte. The default is 2347

byte.
The main purpose of enabling RTS by changing RTS threshold is to reduce possible
collisions due to hidden wireless clients. RTS in AP will be enabled automatically if
the packet size is larger than the Threshold value. By default, RTS is disabled in a
normal environment supports non-jumbo frames.
Short Preamble : By default, it's "Auto". To Disable is to use Long 128-bit Preamble

Synchronization field.
The preamble is used to signal "here is a train of data coming" to the receiver. The
short preamble provides 72-bit Synchronization field to improve WLAN
transmission efficiency with less overhead.
Tx Burst : By default, it's "Enable". To Disable is to deactivate Tx Burst.

With TX burst enabled, AP will send many packets in a burst, without collision detection
and RTS/CTS for each packet. TX Burst have better throughput but cause interference
with other APs in channel.
WMM : By default, it's "Disable".

have higher priority.
