Fragment Threshold: 

specifies the maximum size for a packet before data is fragmented 

into multiple packets. The range is 256-2346 bytes. Setting the Fragment Threshold too low 
may result in poor network performance. The use of fragment can increase the reliability of 
frame transmissions. Because of sending smaller frames, collisions are much less likely to 
occur. However, lower values of the Fragment Threshold will result in lower throughput as 
well.  Minor  or  no  modifications  of  the  Fragmentation  Threshold  value  is  recommended 
while default setting of 2346 is optimum in most of the wireless network use cases. 

RTS Threshold:

 determines the packet size of a transmission and, through the use of an 

access point, helps control traffic flow. The range is 0-2347 bytes. The default value is 2347, 
which means that RTS is disabled. 

Beacon  Interval: 

By  default,  it  is  set  to  100ms.  Higher  Beacon  interval  will  improve  the 

device’s  wireless  performance  and  is  also  power-saving  for  client  side.  If  this  value  set 
lower than 100ms, it will speed up the wireless client connection. 

Data Rates: 

you can choose the wireless data rate. This router provides three options. Be 

default, it is Default (1-2-5.5-11Mbps).

TX Power: 

display the data transmission rate power.   

Preamble type:

 it is to define the length of the sync field in an 802.11 packet. Most modern 

wireless network uses shot preamble with 56 bit sync filed.
