„

Fragmentation: When the size of a unicast frame exceeds the fragmentation

threshold, it will be fragmented before the transmission. It should have a value of

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.

„

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.

Hide SSID: Enable Hide SSID will make the AP network’s SSID invisible. A device

can link with the AP only if correct SSID name is entered.

„

Isolation: Enable Isolation will prevent wireless clients to see each other on the
