SSID Profile

The SSID (Service Set IDentifier) identifies the Service Set with which a wireless

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

have the same SSID. Select an

SSID Profile

from the drop-down list box.

Note: If you are configuring the NWA from a computer connected to the wireless

LAN and you change the NWA’s SSID or security settings, you will lose your

wireless connection when you press

Apply

to confirm. You must then

change the wireless settings of your computer to match the NWA’s new

settings.

Channel

Select the operating frequency/channel depending on your particular region from

the drop-down list box.

Channel Width

This field displays only when you select

802.11 b/g/n

in the

802.11 Wireless

Mode

field.

A standard 20MHz channel offers transfer speeds of up to 150Mbps whereas a

40MHz channel uses two standard channels and offers speeds of up to 300Mbps.

However, not all devices support 40MHz channels.

Select the channel bandwidth you want to use for your wireless network.

It is recommended that you select

20/40

(20/40 MHz). This allows the NWA to

adjust the channel bandwidth depending on network conditions.

Select

20 MHz

if you want to lessen radio interference with other wireless devices

in your neighborhood.

Advanced Settings

Beacon Interval

When a wirelessly network device sends a beacon, it includes with it a beacon

interval. This specifies the time period before the device sends the beacon again.

The interval tells receiving devices on the network how long they can wait in

lowpower mode before waking up to handle the beacon. A high value helps save

current consumption of the access point.

DTIM Interval

Delivery Traffic Indication Message (DTIM) is the time period after which

broadcast and multicast packets are transmitted to mobile clients in the Active

Power Management mode. A high DTIM value can cause clients to lose

connectivity with the network.

Output Power

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

an area, decrease the output power of the NWA to reduce interference with other

APs. Select one of the following

Full

(Full Power),

50%

,

25%

,

12.5%

or

Min

(Minimum). See the product specifications for more information on your NWA’s

output power.

Preamble Type

Select

Dynamic

to have the AP automatically use short preamble when wireless

adapters support it, otherwise the AP uses long preamble.

Select

Long

if you are unsure what preamble mode the wireless adapters support,

and to provide more reliable communications in busy wireless networks.

RTS/CTS

Threshold

(Request To Send) The threshold (number of bytes) for enabling RTS/CTS

handshake. Data with its frame size larger than this value will perform the RTS/

CTS handshake. Setting this attribute to be larger than the maximum MSDU (MAC

service data unit) size turns off the RTS/CTS handshake. Setting this attribute to

its smallest value (1) turns on the RTS/CTS handshake.

Fragmentation

The threshold (number of bytes) for the fragmentation boundary for directed

messages. It is the maximum data fragment size that can be sent.
