Wireless Settings

Beacon Interval: The Beacon Interval specifies the duration between the beacon packets. The AP shall

periodically transmit special frames called beacons that contain information for synchronization between

the participating stations. The range for the Beacon Interval is between 20-1000 with a typical value of 100.

RTS Threshold: The value should remain on its default setting 2432 bytes. If you encounter any date flow,

only minor modifications are recommended.

Fragmentation Threshold: The value indicates how much of the network resources devoted to recovering

packet errors. The value should remain at its default setting of 2432 bytes. If you have decreased this value

and experience high packet error rates, you can increase it again, but will likely decrease overall network

performance.

Authentication Type: It can be selected for “Open System”, “Shared Key” or “Both” for the indication of an

authentication algorithm. “Shared Key” is to be selected while the WEP for PC card and Access Point are

both enabled and setup with the same passphrase key. And “Open System” is for disabled WEP in Wire-

less Network system.

DTIM Interval: DTIM is always a multiple of the beacon Period and determines how often a beacon con-

tains a Delivery Traffic Indicator Message (DTIM). This message informs stations in power-save mode that

a packet is waiting for them. Suggested value is 2.

Preamble Type: There is the “Long” or “Short” selection to ensure that systems receiving the information

correctly interpret when the data transmission starts. To select “long” Preamble may be used to minimize

overhead and “Long” to maximize the network data throughput. The default value will be set for “Long”.

Basic Rate: The basic transfer rate is to set based on the speed of the wireless network system. For slower

network system is to be selected 1-2 Mbps and faster network 1-2-5.5-11 Mbps.

Auto Rate Fall Back setting allows you to have flexible automatic data rate adjustment according to the

connection situation.
