DESCRIPTION

 

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.

 

 

In this field, select the SSID profile of the AP you want to use. Click Apply.

 

 

The SSID used in the selected SSID profile automatically changes to be the one you select

 

 

in the Site Survey screen.

 

 

Set the security configuration for this operating mode in the Wireless LAN > Security

 

 

screen. Check the Dashboard screen to check if the settings you set show in the WLAN

 

 

information.

 

 

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

This shows the operating frequency/channel in use. This field is read-only when you select

 

 

Client as your operation mode.

 

 

 

 

Channel Width

This field is not available in the NWA1123-NI.

 

 

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 20/40MHz. This allows the NWA to adjust the channel

 

 

bandwidth depending on network conditions.

 

 

Select 20MHz if you want to lessen radio interference with other wireless devices in your

 

 

neighborhood or the AP do not support channel bonding.

 

 

 

Advanced Settings

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% or 12.5%. See the product specifications for

 

more information on your NWA’s output power.

 

 

Preamble Type

Select Dynamic to have the NWA automatically use short preamble when the wireless

 

network your NWA is connected to supports it, otherwise the NWA uses long preamble.

 

Select Long preamble if you are unsure what preamble mode the wireless device your NWA

 

is connected to supports, and to provide more reliable communications in busy wireless

 

networks.

 

 

RTS/CTS

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

Threshold

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.

 

 

 

 

Extension

You can use CTS to self or RTS-CTSprotection mechanism to reduce conflicts with other

channel

wireless networks or hidden wireless clients. The throughput of RTS-CTSis much lower

protection mode

than CTS to self. Using this mode may decrease your wireless performance.

 

 

A-MPDU

This field is not available in the NWA1100-NH and NWA1123-NI.

Aggregation

Select to enable A-MPDU aggregation.

 

 

Message Protocol Data Unit (MPDU) aggregation collects Ethernet frames along with their

 

802.11n headers and wraps them in a 802.11n MAC header. This method is useful for

 

increasing bandwidth throughput in environments that are prone to high error rates.
