DESCRIPTION

 

 

 

 

 

 

ESSID

(Extended Service Set IDentity) The ESSID identifies the Service Set with which a

 

 

 

wireless station is associated. Wireless stations associating to the access point (AP)

 

 

 

must have the same ESSID. Enter a descriptive name (up to 32 printable 7-bit ASCII

 

 

 

characters) for the wireless LAN.

 

 

 

If you are configuring the ZyAIR from a computer connected to the wireless LAN and you

 

 

 

change the ZyAIR’s ESSID or WEP settings, you will lose your wireless connection when

 

 

 

you click Apply. You must then change the wireless settings of your computer to match

 

 

 

the ZyAIR’s new settings.

 

 

 

 

 

 

Channel

Select a channel from the drop-down list box depending on your particular region.

 

 

 

 

 

 

WEP

Select Disable to allow all wireless computers to communicate with the access points

 

 

 

without any data encryption.

 

 

 

Select Mandatory to enable WEP data encryption. Then click WEP Key Setup to open a

 

 

 

screen where you can configure the WEP keys on the ZyAIR. Refer to Section 18.3.1.

 

 

Beacon Interval

Set the number of milliseconds that should pass between sending out a beacon. Enter a

 

 

 

time period between 1 and 1000. The default is 100.

 

 

RTS Threshold

Enter a value between 0 and 2442 to enable an RTS/CTS handshake to avoid

 

 

 

retransmitting due to hidden nodes. The default is 2432.

 

 

Fragmentation

Enter a value between 256 and 2446 to enable a fragmentation threshold. This sets the

 

 

Threshold

maximum size of data fragments that can be sent. The default is 2432. Use a low setting

 

 

 

if there is a great deal of radio interference.

 

 

 

 

 

 

DTIM Interval

This setting, always a multiple of the beacon period, determines how often the beacon

 

 

 

contains a delivery traffic indication message (DTIM). The DTIM tells client devices that

 

 

 

are set to power-save that a packet is waiting for them. The DTIM Interval’s valid range is

 

 

 

1 to 65535.

 

 

Transmission

The basic transfer rates should be set depending on the speed of your wireless network.

 

 

Rates

The default setting is 1-2-5.5-11 (Mbps).

 

 

 

 

 

 

Preamble Type

Select either Short Preamble or Long Preamble.

 

 

 

 

 

 

Antenna

Select Left Antenna if your device has removable antennas and you install a high-gain

 

 

Selection

antenna on the connector on the left (when you look at the device's rear panel).

 

 

 

Select Right Antenna if your device has removable antennas and you install a high-gain

 

 

 

antenna on the connector on the right (when you look at the device's rear panel).

 

 

 

Select Diversity Antenna (default) to have the device use the antenna that receives the

 

 

 

best signal.
