This chapter introduces the main applications and features of the NWA. It also discusses the ways
you can manage your NWA.
1.1 Introducing the NWA
This User’s Guide covers the following models: NWA1121-NI, NWA1123-NI and NWA1123-AC. Your
NWA is an IPv6 wireless AP (Access Point) that can function in several wireless modes. It extends
the range of your existing wired network without additional wiring, providing easy network access
to mobile users.

Layer-2 IsolationYesYesYes
The NWA controls network access with MAC address filtering and RADIUS server authentication. It
also provides a high level of network traffic security, supporting IEEE 802.1x, Wi-Fi Protected
Access (WPA), WPA2 and WEP data encryption. Its Quality of Service (QoS) features allow you to
prioritize time-sensitive or highly important applications such as VoIP.
Your NWA is easy to install, configure and use. The embedded Web-based configurator enables
simple, straightforward management and maintenance.
See the Quick Start Guide for instructions on how to make hardware connections.
1.1.1 Dual-Band
The NWA1123-NI or NWA1123-AC is a dual-band AP and able to function both 2.4G and 5G
networks at the same time. You could use the 2.4 GHz band for regular Internet surfing and

Chapter 1 Introducing the NWA
downloading while using the 5 GHz band for time sensitive traffic like high-definition video, music,
and gaming.
Figure 1 Dual-Band Application
1.2 Wireless Modes
The NWA can be configured to use the following WLAN operating modes:
Applications for each operating mode are shown below.
1.2.1 MBSSID
A Basic Service Set (BSS) is the set of devices forming a single wireless network (usually an access
point and one or more wireless clients). The Service Set IDentifier (SSID) is the name of a BSS. In
Multiple BSS (MBSSID) mode, the NWA provides multiple virtual APs, each forming its own BSS and
using its own individual SSID profile.
You can configure multiple SSID profiles, and have all of them active at any one time.
NUMBER OF
SUPPORTED SSID
REPEATER FUNCTION AP FUNCTION
You can assign different wireless and security settings to each SSID profile. This allows you to
compartmentalize groups of users, set varying access privileges, and prioritize network traffic to
and from certain BSSs.
NWA1120 Series User’s Guide
11
Chapter 1 Introducing the NWA
To the wireless clients in the network, each SSID appears to be a different access point. As in any
wireless network, clients can associate only with the SSIDs for which they have the correct security
settings.
For example, you might want to set up a wireless network in your office where Internet telephony
(VoIP) users have priority. You also want a regular wireless network for standard users, as well as a
‘guest’ wireless network for visitors. In the following figure, VoIP_SSID users have QoS priority,
SSID01 is the wireless network for standard users, and Guest_SSID is the wireless network for
guest users. In this example, the guest user is forbidden access to the wired Land Area Network
(LAN) behind the AP and can access only the Internet.
Figure 2 Multiple BSSs
1.2.2 Wireless Client
The NWA can be used as a wireless client to communicate with an existing network.
Note: The NWA1123-NI or NWA1123-AC is a dual-band AP which contains two different
types of wireless radios to transmit at 2.4 GHz and 5 GHz bands separately and
simultaneously. If one of the NWA1123-NI wireless radio is set to work in client
mode, the other radio will be disabled automatically.

NWA1120 Series User’s Guide
Chapter 1 Introducing the NWA
In the figure below, the printer can receive requests from the wired computer clients A and B via
the NWA in Client mode (Z) using only the 2.4 GHz band.
Figure 3 Wireless Client Application
NWA1120 Series User’s Guide
13
Chapter 1 Introducing the NWA
1.2.3 Root AP
In Root AP mode, the NWA (Z) can act as the root AP in a wireless network and also allow repeaters
(X and Y) to extend the range of its wireless network at the same time. In the figure below, both
clients A, B and C can access the wired network through the root AP.
Figure 4 Root AP Application
On the NWA in Root AP mode, you can have multiple SSIDs active for reqular wireless connections
and one SSID for the connection with a repeater (repeater SSID). Wireless clients can use either
SSID to associate with the NWA in Root AP mode. A repeater must use the repeater SSID to
connect to the NWA in Root AP mode.
When the NWA is in Root AP mode, repeater security between the NWA and other repeater is
independent of the security between the wireless clients and the AP or repeater. If you do not
enable repeater security, traffic between APs is not encrypted. When repeater security is enabled,
both APs and repeaters must use the same pre-shared key. See Section 6.6 on page 73 for more
details.
Unless specified, the term “security settings” refers to the traffic between the wireless clients and
the AP. At the time of writing, repeater security is compatible with the NWA only.
1.2.4 Repeater
The NWA can act as a wireless network repeater to extend a root AP’s wireless network range, and
also establish wireless connections with wireless clients.
Using Repeater mode, your NWA can extend the range of the WLAN. In the figure below, the NWA
in Repeater mode (Z) has a wireless connection to the NWA in Root AP mode (X) which is
connected to a wired network and also has a wireless connection to another NWA in Repeater mode
(Y) at the same time. Z and Y act as repeaters that forward traffic between associated wireless
14
NWA1120 Series User’s Guide
Chapter 1 Introducing the NWA
clients and the wired LAN. Clients A and B access the AP and the wired network behind the AP
throught repeaters Z and Y.
Figure 5 Repeater Application
When the NWA is in Repeater mode, repeater security between the NWA and other repeater is
independent of the security between the wireless clients and the AP or repeater. If you do not
enable repeater security, traffic between APs is not encrypted. When repeater security is enabled,
both APs and repeaters must use the same pre-shared key. See Section 6.6 on page 73 for more
details.
Once the security settings of peer sides match one another, the connection between devices is
made.
At the time of writing, repeater security is compatible with the NWA only.
1.3 Ways to Manage the NWA
Use any of the following methods to manage the NWA.
• Web Configurator. This is recommended for everyday management of the NWA using a
(supported) web browser.
• FTP (File Transfer Protocol) for firmware upgrades and configuration backup and restore.
• SNMP (Simple Network Management Protocol). The device can be monitored by an SNMP
manager.
NWA1120 Series User’s Guide

Chapter 1 Introducing the NWA
1.4 Configuring Your NWA’s Security Features
Your NWA comes with a variety of security features. This section summarizes these features and
provides links to sections in the User’s Guide to configure security settings on your NWA. Follow the
suggestions below to improve security on your NWA and network.
1.4.1 Control Access to Your Device
Ensure only people with permission can access your NWA.
• Control physical access by locating devices in secure areas, such as locked rooms. Most NWAs
have a reset button. If an unauthorized person has access to the reset button, they can then
reset the device’s password to its default password, log in and reconfigure its settings.
• Change any default passwords on the NWA, such as the password used for accessing the NWA’s
web configurator (if it has a web configurator). Use a password with a combination of letters and
numbers and change your password regularly. Write down the password and put it in a safe
place.
•See Section 11.5 on page 113 for instructions on changing your password.
• Configure remote management to control who can manage your NWA. See Chapter 9 on page 94
for more information. If you enable remote management, ensure you have enabled remote
management only on the IP addresses, services or interfaces you intended and that other remote
management settings are disabled.
1.4.2 Wireless Security
Wireless devices are especially vulnerable to attack. Take the following measures to improve
wireless security.
• Enable wireless security on your NWA. Choose the most secure encryption method that all
devices on your network support. See Section 6.6 on page 73 for directions on configuring
encryption. If you have a RADIUS server, enable IEEE 802.1x or WPA(2) user identification on
your network so users must log in. This method is more common in business environments.
• Hide your wireless network name (SSID). The SSID can be regularly broadcast and unauthorized
users may use this information to access your network. See Section 6.5 on page 71 for directions
on using the web configurator to hide the SSID.
• Enable the MAC filter to allow only trusted users to access your wireless network or deny
unwanted users access based on their MAC address. See Section 6.9 on page 83 for directions on
configuring the MAC filter.
1.5 Good Habits for Managing the NWA
Do the following things regularly to make the NWA more secure and to manage it more effectively.
• Change the password. Use a password that’s not easy to guess and that consists of different
types of characters, such as numbers and letters.
• Write down the password and put it in a safe place.
16
NWA1120 Series User’s Guide
• Back up the configuration (and make sure you know how to restore it). Restoring an earlier
working configuration may be useful if the device becomes unstable or even crashes. If you
forget your password, you will have to reset the NWA to its factory default settings. If you backed
up an earlier configuration file, you would not have to totally re-configure the NWA. You could
simply restore your last configuration.

CHAPTER 4
This chapter first provides an overview of how to configure the wireless LAN on your NWA, and then
gives step-by-step guidelines showing how to configure your NWA for some example scenarios.
4.1 How to Configure the Wireless LAN
This section illustrates how to choose which wireless operating mode to use on the NWA and how to
set up the wireless LAN in each wireless mode. See Section 4.1.2 on page 28 for links to more
information on each step.
4.1.1 Choosing the Wireless Mode
•Use MBSSID (Multiple Basic Service Set Identifier) operating mode if you want to use the NWA
as an access point with some groups of users having different security or QoS settings from other
groups of users. See Section 1.2.1 on page 11 for details.
•Use Client operating mode if you want to use the NWA to access a wireless network. See Section
1.2.2 on page 12 for details.
•Use Root AP operating mode if you want to allow wireless clients to access your wired network
through the NWA and also have repeaters communicate with the NWA to expand wireleass
coverage. See Section 1.2.3 on page 14 for details.
•Use Repeater operating mode if you want to use the NWA to communicate with the root AP or
other repeaters. See Section 1.2.4 on page 14 for details.

4.2 How to Configure Multiple Wireless Networks
In this example, you have been using your NWA as an access point for your office network. Now
your network is expanding and you want to make use of the MBSSID feature (see Section 6.4.4 on
NWA1120 Series User’s Guide28
Chapter 4 Tutorial
Z

B
page 68) to provide multiple wireless networks. Each wireless network will cater to a different type
of user.
You want to make three wireless networks: one standard office wireless network with all the same
settings you already have, another wireless network with high priority QoS settings for Voice over
IP (VoIP) users, and a guest network that allows visitors to access only the Internet and the
network printer.
To do this, you will take the following steps:
1Edit the SSID profiles.
2Change the operating mode from Root AP to MBSSID and reactivate the standard network.
3Configure different security modes for the networks.
4Configure a wireless network for standard office use.
5Configure a wireless network for VoIP users.
6Configure a wireless network for guests to your office.
The following figure shows the multiple networks you want to set up. Your NWA is marked Z, the
main network router is marked A, and your network printer is marked B.
The standard network (SSID01) has access to all resources. The VoIP network (VoIP_SSID) has
access to all resources and a high QoS priority. The guest network (Guest_SSID) has access to the
Internet and the network printer only, and a low QoS priority.
NWA1120 Series User’s Guide

Chapter 4 Tutorial
To configure these settings, you need to know the Media Access Control (MAC) addresses of the
devices you want to allow users of the guest network to access. The following table shows the
addresses used in this example.
