Advanced Settings
Contention
Slot
Select “Short” or “Long” – this value is used for contention
windows in 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 AP and roaming wireless adapters. The default
value is “Short Preamble”.
Guard
Interval
Set the guard interval. A shorter interval can improve
performance.
802.11n
Protection
Enable/disable 802.11n protection, which increases reliability
but reduces bandwidth (clients will send Request to Send
(RTS) to AP, and AP will broadcast Clear to Send (CTS), before
a packet is sent from client.)
CE Adaptive
The measurement procedure follows clause 5.3.11.2.2 of the
ETSI EN 300 328 V1.8.1
DTIM Period
Set the DTIM (delivery traffic indication message) period value
of the wireless radio. The default value is 1.
RTS
Threshold
Set the RTS threshold of the wireless radio. The default value
is 2347.
Fragment
Threshold
Set the fragment threshold of the wireless radio. The default
value is 2346.
Multicast
Rate
Set the transfer rate for multicast packets or use the “Auto”
setting.
Tx Power
Set the power output of the wireless radio. You may not
require 100% output power. Setting a lower power output can
enhance security since potentially malicious/unknown users
in distant areas will not be able to access your signal.
Beacon
Interval
Set the beacon interval of the wireless radio. The default
value is 100.
Station idle
timeout
Set the interval for keepalive messages from the AP to a
wireless client to verify if the station is still alive/active.
