256-2346 bytes, with a default of 2346. If you experience a high packet error rate,
you should slightly decrease the Fragmentation Threshold.
 RTS Threshold: RTS/CTS frames are used to gain control of the medium for
transmission. Any unicast (data or control) frames larger than specified RTS threshold
must be transmitted following the RTS/CTS handshake exchange mechanism. The
RTS threshold should have a value between 256-2347 bytes, with a default of 2347. It
is recommended that this value does not deviate from the default too much.
 Beacon Interval: The device broadcasts beacon frames regularly to announce its
existence. The beacon Interval specifies how often beacon frames are transmitted in
time unit of milliseconds. The default value is 100, and a valid value should be between
1 and 65,535.
 Inactivity Time: The wireless client will be dropped from the network when they are
inactive for this amount of time.
 AckTimeOut: When a packet is sent out from one wireless station to the other, it will
waits for an Acknowledgement frame from the remote station. The station will only
wait for a certain amount of time, this time is called the ACK timeout. In most
conditions, please put ACKtimeout value at zero(default value). The AP will calculate
the ACKtimeout automatically when the value is zero. However, you can also enter
the ACKtimeout manually.
 Preamble Type: A preamble is a signal used in wireless environment to synchronize
the transmitting timing including Synchronization and Start frame delimiter. In a "noisy"
network environment, the Preamble Type should be set to Long Preamble. The Short
Preamble is intended for applications where minimum overhead and maximum
performance is desired. If in a "noisy" network environment, the performance will be
decreased.
 IAPP: IAPP (Inter Access Point Protocol) is designed for the enforcement of unique
association throughout a ESS (Extended Service Set) and a secure exchange of
station’s security context between current access point (AP) and new AP during
handoff period.
 BG Protection: The 802.11g standard includes a protection mechanism to ensure
mixed 802.11b and 802.11g operation. If there is no such kind of mechanism exists, the
two kinds of standards may mutually interfere and decrease network’s performance..
