These settings are only for more technically advanced users who have suf fi cient knowledge
about wireless LAN. These settings should not be changed until you know what effect the
change will hace on your AP.
You can change:
• Fragment Threshold: This speci fi es the maximum size of the package during the
fragmentation of data to be transmitted.
• RTS Threshold: You can adjust the RTS Threshold here. The valid range should be
0-2347 and the default range is 2347. If a network package is smaller than the preset RTS
Threshold, the RTS/CTS mechanism will not be activated.
• Beacon Interval: It is the time interval of this router to broadcast a guide. A guide is used
to synchronize the wireless network. The valid range is 20-1024 ms, the default one is 100.
• Preamble Type: “Short Preamble” is suitable for heavy wireless network. “Long Preamble”
provides a more reliable communication. The default is “Long Preamble”.
• Short GI: Using a short guard interval can increase the performance. However, it also
may increase the error rate in some installations due to increased sensitivity of the
radio-frequency re fl ections.
