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.

Select SSID Profile

An SSID profile is the set of parameters relating to one of the NWA’s BSSs.

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

wireless station is associated. Wireless stations associating with the access

point (AP) must have the same SSID.

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.

Index

Select the check box to activate an SSID profile.

Active

Select the check box to enable the bridge connection. Otherwise, clear the

check box to disable it. The first profile is always active.

Profile

Select the profile(s) of the SSIDs you want to use in your wireless network.

You can have up to four BSSs running on the NWA simultaneously.

Configure SSID profiles in the

SSID

screen.

Advanced Settings

Beacon Interval

When a wirelessly networked 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.
