Wireless Mode Select 802.11b only to allow only IEEE 802.11b compliant WLAN devices to

associate with the device.

Select 802.11g only to allow only IEEE 802.11g compliant WLAN devices to

associate with the device.

Select Auto (11g/11b) to allow either IEEE 802.11b or IEEE 802.11g compliant

WLAN devices to associate with the device. The transmission rate of your device

might be reduced.

Advanced Settings

Beacon Interval Set the number of milliseconds that should pass between the sending out of

beacons.

Intra-BSS Traffic Intra-BSS traffic is traffic between wireless stations in the same BSS.

Enable Intra-BSS traffic to allow wireless stations connected to the device to

communicate with each other.

Disable Intra-BSS traffic to only allow wireless stations to communicate with the

wired network, not with each other.

DTIM Interval Set the interval for wireless clients in sleep mode to wake up and check for

multicast or broadcast traffic.

The AP includes a Delivery Traffic Indication Message (DTIM) in the beacon to

notify wireless clients in sleep mode that there is a multicast or broadcast packet

awaiting delivery. The interval is a multiple of the beacon interval. For example, if

the beacon interval is 100 milliseconds and the DTIM interval is 2, the AP includes

a DTIM with every second beacon (or every 200 milliseconds).

Number of

Wireless Stations

Allowed to

Associate:

Use this field to set a maximum number of wireless stations that may connect to

the device.

Enter the number (from 1 to 32) of wireless stations allowed.

Radio Enable Turn on the wireless adapter to allow wireless communications between the device

and other IEEE 802.11b and IEEE 802.11g compliant wireless devices. Turn off

the wireless adapter to stop wireless communications between the device and

other IEEE 802.11b and IEEE 802.11g compliant wireless devices.

Output Power

Management

Set the output power of the device in this field. If there is a high density of APs

within an area, decrease the output power of the device to reduce interference with

other APs.

The options are Full, 50%, 25%, 12% and Min.

Data Rate

Management

Use this field to select a maximum data rate for the wireless connection(s). Please

note that this is a total rate to be shared by all of the device’s wireless connections.

Preamble Type Preamble is used to signal that data is coming to the receiver.

Short preamble increases performance as less time sending preamble means

more time for sending data. All IEEE 802.11b compliant wireless adapters support

long preamble, but not all support short preamble.

Select Long preamble if you are unsure what preamble mode the wireless

adapters support, and to provide more reliable communications in busy wireless

networks.

Select Short preamble if you are sure the wireless adapters support it, and to

provide more efficient communications.

Select Auto to have the device automatically use short preamble when all wireless

clients support it, otherwise the device uses long preamble.

Note: The device and the wireless stations MUST use the same

preamble mode in order to communicate.
