◗ Advanced Settings
These advanced settings are preconfigured with the optimum settings for your
wireless module. Changing any of these settings may negatively affect the
module’s performance. For best results, leave these settings at their default
values.
• Beacon Interval
The beacon is a uniframe system packet broadcast by the AP to keep the
module synchronized. Enter a value in this field between 20 and 1000
(milliseconds) that specifies the beacon interval. The default value is 100.
• Delivery Traffic Indication Message (DTIM Period)
Enter a value between 1 and 255 that specifies the Delivery Traffic
Indication Message (DTIM). Increasing this interval allows the station to
sleep for longer periods of time resulting in power savings (in exchange
for some degradation in performance). The default value is 1.
• Fragment Length
Enter a value between 256 and 2346. This setting determines the size of
the wireless frame. Wireless frames are reassembled by the wireless
module before being forwarded to the Ethernet port, but only if the frame
is smaller than the Ethernet MTU (1536 bytes). The default value is 2346.
• RTS/CTS Threshold
This is a value that determines at what frame length the RTS-CTS function
is triggered. By default, the threshold is set at its highest value. A lower
value means that the RTS-CTS function is triggered for smaller frame
lengths. A lower threshold value may be necessary in environments with
excessive signal noise or hidden nodes, but may result in some
performance degradation. Enter a value between 256 and 2346 to specify
the RTS/CTS threshold. The default value is 2346.
When finished, click on the Update button to update this page and apply your
changes, then click on the Reboot button to reboot the module. If necessary, you
can click on the Refresh button in the toolbar to reset all parameters on this page to
their original values.
