Advanced Settings 

 

This tab allows you to set the advanced wireless options. The options included 

are  Authentication  Type,  Fragment  Threshold,  RTS  Threshold,  Beacon 

Interval, and Preamble Type. You should not change these parameters unless 

you know what effect the changes will have on the router. 

 

 

 

Fragment Threshold

 "Fragment Threshold" specifies the maximum size of a 

packet  during  the  fragmentation  of  data  to  be  transmitted.  If  you  set  this 

value too low, it will result in bad performance. 

RTS Threshold

 When the packet size is smaller then the RTS threshold, the 

wireless router will not use the RTS/CTS mechanism to send this packet.  

Beacon Interval

 is the interval of time that this wireless router broadcasts a 

beacon. A Beacon is used to synchronize the wireless network.  

DTIM  period

 

is  a  countdown  mechanism  for  WLAN  Access  Points  changing 

this value will affect your wireless performance and may improve stability. 

Preamble  Type

  The  “Long  Preamble”  can  provide  better  wireless  LAN 

compatibility  while  the  “Short  Preamble”  can  provide  better  wireless  LAN 

performance. 

Broadcast  ESSID

  If  you  enabled  “Broadcast  ESSID”,  every  wireless  station 

located within the coverage of this access point can discover this access point
