RTS mechanism will be activated if the data size exceeds the value you set..

The default value is 2347.

Warning: Enabling RTS Threshold will cause redundant network overhead

that could negatively affect the throughput performance instead of providing

a remedy.

This value should remain at its default setting of 2347. Should you encounter

inconsistent data flow, only minor modifications of this value are recommended.

Beacon Interval

Beacon Interval is the amount of time between beacon transmissions. Before

a station enters power save mode, the station needs the beacon interval to

know when to wake up to receive the beacon (and learn whether there are

buffered frames at the access point).

Data Rate

By default, the unit adaptively selects the highest possible rate for

transmission. Select the basic rates to be used among the following options:

Auto, 1, 2, 5.5, 11or 54 Mbps. For most networks the default setting is Auto

which is the best choice. When Auto is enabled the transmission rate will

select the optimal rate. If obstacles or interference are present, the system will

automatically fall back to a lower rate.

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.

Broadcast SSID

Select enabled to allow all the wireless stations to detect the SSID of this

Access Point.

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.

802.11g 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.
