NWA1121-NI User’s Guide

The following table describes the general wireless LAN labels in this screen.

Wireless LAN > Wireless Settings: Root AP

Basic Settings

Wireless LAN 
Interface

Select the check box to turn on the wireless LAN on the NWA1121-NI.

Operation Mode

Select Root AP from the drop-down list. 

Wireless Mode

Select 802.11b/g to allow both IEEE802.11b and IEEE802.11g compliant WLAN devices 
to associate with the NWA1121-NI. The transmission rate of your NWA1121-NI might be 
reduced.

Select 802.11b/g/n to allow IEEE802.11b, IEEE802.11g and IEEE802.11n compliant 
WLAN devices to associate with the NWA1121-NI. The transmission rate of the NWA1121-
NI might be reduced.

Select 802.11n to allow only IEEE802.11n compliant WLAN devices to associate with the 
NWA1121-NI. 

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 802.11n or 802.11b/g/n in the 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 20/40MHz. This allows the NWA1121-NI 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 wireless clients do not support channel bonding.

Select 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.

 You can have up to four SSIDs active at the same time.

Note: If you are configuring the NWA1121-NI from a computer connected to the wireless 

LAN and you change the NWA1121-NI’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 NWA1121-NI’s new settings.

#

This is the index number of each SSID profile.

Activve

Select the check box to enable an SSID profile. Otherwise, clear the check box.

Profile

Universal Repeater Settings

The Universal repeater function allows the NWA1121-NI in root AP or repeater mode to set up a wireless 
connection between it and another NWA1121-NI in root AP or repeater mode.

 

Note: 

Universal repeater security

 is independent of the security settings between the NWA1121-NI and any 

wireless clients.

Local MAC 
Address

Local MAC Address is the MAC address of your NWA1121-NI. 

Universal 
Repeater SSID 
Profile

Select the SSID profile you want to use for 

universal repeater connections

.

Note: You can only configure None, WPA-PSK or WPA2-PSK security mode for the SSID 

used by a universal repeater connection
