These settings are for experienced users only. Please do not change any of the
values on this page unless you are already familiar with these functions.
Changing these settings can adversely affect the performance of your access point.
Contention Slot Select “Short” or “Long” – this value is used for contention
windows in WMM (see 4-3-6. WMM).
Preamble Type Set the wireless radio preamble type. The preamble type in
802.11 based wireless communication defines the length of
the CRC (Cyclic Redundancy Check) block for communication
between the access point and roaming wireless adapters. The
default value is “Short Preamble”.
Guard Interval Set the guard interval. A shorter interval can improve
performance.
802.11g Protection Enable/disable 802.11g protection, which increases reliability
but reduces bandwidth (clients will send Request to Send (RTS)
to access point, and access point will broadcast Clear to Send
(CTS), before a packet is sent from client.)
