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.

TX Power Level

For countries that impose limit on WLAN output power, it might be necessary

to reduce TX (transmit) power. There are 7 TX Power Levels to choose

from — select a level to make sure that the output power measured at the

antenna end will not exceed the legal limit in your country.

Enable Watch dog

Check and enable this watch dog function

Watch Interval

Setup the interval time for watch dog function between 1 to 60 mins

Watch Host

Enter the watch dog host ip address .

ACK Timeout

When a packet is sent out from one wireless station to the other, it will waits

for an Acknowledgement frame from the remote station. If the ACK is NOT

received within that timeout period then the packet will be re-transmitted

resulting in reduced throughput. If the ACK setting is too high then

throughput will be lost due to waiting for the ACK Window to timeout on lost

packets. By having the ability to adjust the ACK setting we can effectively

optimize the throughput over long distance links. This is especially true for

802.11a and 802.11g networks

You can set as default for auto adjustment.
