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.
