NWA1100-N User’s Guide

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 of the AP you want to use (click Site Survey button 
for a list of available APs). Click Apply. Set the security configuration for this 
operating mode in the Wireless > Security screen. Check the Status 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 Wireless Client as your operation mode. 

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

MAC Clone

Choose Manual to configure the NWA’s MAC address by cloning the MAC address 
from a computer on your LAN. Choose Auto to use the factory default MAC 
address of your NWA. 

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 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 
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. 

Extension 
channel 
protection mode

You can use CTS to self or RTS-CTS protection mechanism to reduce conflicts 
with other wireless networks or hidden wireless clients. The throughput of RTS-
CTS is much lower than CTS to self. Using this mode may decrease your wireless 
performance.
