Preamble Mode:
A preamble (especially the 802.11b High Rate/DSSS
PHY field; 56 digits synchronized field for short preamble) defines the
length of the CRC correction block for communication between wireless
devices. Short preamble should be applied in a network with intense
traffics. It helps improve the efficiency of a wireless network responding
to applications that have high requirement of real-time, such as strea-
ming video and voice-over-IP telephony.
Guard Interval:
Short GI: The interval is 400 ns. When short GI is enabled, ISY
Wireless Range Extender can receive and send short-frame-interval
packets. This helps improve the transmission rate of ISY Wireless
Range Extender.
Long GI: The interval is 800 ns.
Transmit Power Control:
Set the transmit power of the wireless
network. It is recommended to use the default setting of 100%.
Router’s PIN:
Display the PIN to be used for the wireless client when
wireless settings of the router are configured through WPS.

the WPS Setup menu item is greyed out.
Disable Router’s PIN:
The PIN mode function in the WPS Setup page is
available only when the Disable Router’s PIN check box is not selected. If
the check box is selected, the PIN mode option is unavailable.
