LABEL DESCRIPTION
Wireless Advanced Setup
RTS/CTS
Threshold
Enter a value between 0 and 2432.
Fragmentation
Threshold
It is the maximum data fragment size that can be sent. Enter a value between 256 and
2432.
Preamble Preamble is used to signal that data is coming to the receiver.
Short preamble increases performance as less time sending preamble means more
time for sending data. All IEEE 802.11b compliant wireless adapters support long
preamble, but not all support short preamble.
Select
Long preamble if you are unsure what preamble mode the wireless adapters
support, and to provide more reliable communications in busy wireless networks.
Select
Short preamble if you are sure the wireless adapters support it, and to provide
more efficient communications.
Note: The Prestige and the wireless stations MUST use the same
preamble mode in order to communicate.
802.11 Mode Select 802.11b Only to allow only IEEE 802.11b compliant WLAN devices to
associate with the Prestige.
Select
802.11g Only to allow only IEEE 802.11g compliant WLAN devices to
associate with the Prestige.
Select
Mixed to allow either IEEE802.11b or IEEE802.11g compliant WLAN devices
to associate with the Prestige. The transmission rate of your Prestige might be
reduced.
