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
Your NWA extends the range of your existing wired network without additional wiring, providing
easy network access to mobile users.
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.
CHAPTER 1
Introducing the NWA
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.
1.2 Applications for the NWA
The NWA can be configured to use the following WLAN operating modes:
1 Access Point
2 Bridge/Repeater
3 AP + Bridge
4 Wireless Client
5 Multi SSID
Applications for each operating mode are shown below.
NWA1100-N User’s Guide 11
Chapter 1 Introducing the NWA
1.2.1 Access Point
The NWA is an ideal access solution for wireless Internet connection. A typical Internet access
application for your NWA is shown as follows. Stations A, B and C can access the wired network
through the NWAs.
Figure 1 Access Point Application
1.2.2 Bridge / Repeater
The NWA can act as a wireless network bridge and establish wireless links with other APs. In the
figure below, the two NWAs (A and B) are connected to independent wired networks and have a
bridge connection (A can communicate with B) at the same time. A NWA in repeater mode (C) has
no Ethernet connection.
When the NWA is in Bridge / Repeater mode, security between APs (the Wireless Distribution
System or WDS) is independent of the security between the wireless stations and the AP. If you do
not enable WDS security, traffic between APs is not encrypted. When WDS security is enabled, both
APs must use the same pre-shared key. See Section 5.4.2 on page 53 for more details.
Once the security settings of peer sides match one another, the connection between devices is
made.
12
NWA1100-N User’s Guide
Chapter 1 Introducing the NWA
At the time of writing, WDS security is compatible with other ZyXEL NWA-series access points only.
Refer to your other access point’s documentation for details.
Figure 2 Bridge Application
Figure 3 Repeater Application
1.2.2.1 Bridge / Repeater Mode Example
In the example below, when both NWAs are in bridge mode, they form a WDS (Wireless Distribution
System) allowing the computers in LAN 1 to connect to the computers in LAN 2.
Figure 4 Bridging Example
NWA1100-N User’s Guide
13
Chapter 1 Introducing the NWA
Be careful to avoid bridge loops when you enable bridging in the NWA. Bridge loops cause
broadcast traffic to circle the network endlessly, resulting in possible throughput degradation and
disruption of communications. The following examples show two network topologies that can lead
to this problem:
• If two or more NWAs (in bridge mode) are connected to the same hub.
Figure 5 Bridge Loop: Two Bridges Connected to Hub
• If your NWA (in bridge mode) is connected to a wired LAN while communicating with another
wireless bridge that is also connected to the same wired LAN.
Figure 6 Bridge Loop: Bridge Connected to Wired LAN
To prevent bridge loops, ensure that your NWA is not set to bridge mode while connected to both
wired and wireless segments of the same LAN.
1.2.3 AP + Bridge
In AP+Bridge mode, the NWA supports both AP and bridge connection at the same time.
14
In the figure below, A and B use X as an AP to access the wired network, while X and Y
communicate in bridge mode.
Using AP + Bridge mode, your NWA can extend the range of the WLAN. In the figure below, A and
B act as AP + Bridge devices that forward traffic between associated wireless workstations and the
wired LAN.
NWA1100-N User’s Guide
Chapter 1 Introducing the NWA
When the NWA is in AP+Bridge mode, security between APs (the Wireless Distribution System or
WDS) is independent of the security between the wireless stations and the AP. If you do not enable
WDS security, traffic between APs is not encrypted. When WDS security is enabled, both APs must
use the same pre-shared key. See Section 5.4.3 on page 58 for more details.
Unless specified, the term “security settings” refers to the traffic between the wireless stations and
the NWA.
Figure 7 AP + Bridge Application
1.2.4 Wireless Client
The NWA can be used as a wireless client to communicate with an existing network. In the figure
below, the printer can receive requests from the wired computer clients A and B via the NWA in
Wireless Client mode.
Figure 8 Wireless Client Application
NWA1100-N User’s Guide
15
Chapter 1 Introducing the NWA
1.2.5 Multi SSID
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
Multi SSID mode, the NWA provides multiple virtual APs, each forming its own BSS and using its
own individual SSID profile.
You can configure up to eight SSID profiles, and have up to four active at any one time.
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.
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.
Figure 9 Multiple BSSs
1.3 Ways to Manage the NWA
Use any of the following methods to manage the NWA.
16
NWA1100-N User’s Guide
Chapter 1 Introducing the NWA
• Web Configurator. This is recommended for everyday management of the NWA using a
(supported) web browser.
• Command Line Interface. Line commands are mostly used for troubleshooting by service
engineers.
• FTP (File Transfer Protocol) for firmware upgrades.
• SNMP (Simple Network Management Protocol). The device can be monitored by an SNMP
manager.
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 Chapter 11 on page 94 for instructions on changing your password.
• Configure remote management to control who can manage your NWA. See Chapter 12 on page
100 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. If your NWA has a wireless function, 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 7.4 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 6.2 on page 67 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 9.4 on page 88 for directions on
configuring the MAC filter.

CHAPTER 2
Introducing the Web Configurator
This chapter describes how to access the NWA’s web configurator and provides an overview of its
screens.
2.1 Accessing the Web Configurator
1 Make sure your hardware is properly connected and prepare your computer or computer network to
connect to the NWA (refer to the Quick Start Guide).
2 Launch your web browser.
3 Type "192.168.1.2" as the URL (default). The login screen appears.
Figure 11 The Login Screen
4 Type “admin” as the (default) username and “1234” as the (default) password. Click Login.
You should now see the Status screen. See Chapter 2 on page 20 for details about the Status
screen.
Note: For security reasons, the NWA automatically logs you out if there is no activity for
longer than five minutes after you log in. If this happens, simply log back in again.
2.2 Resetting the NWA
If you forget your password or cannot access the web configurator, you will need to use the RESET
button at the rear panel of the NWA. This replaces the current configuration file with the factory-
NWA1100-N User’s Guide 20
default configuration file. This means that you will lose all the settings you previously configured.
The password will be reset to “1234”.
Figure 12 The RESET Button
2.2.1 Methods of Restoring Factory-Defaults
You can erase the current configuration and restore factory defaults in two ways:
Use the RESET button to upload the default configuration file. Hold this button in for about 10
seconds (the lights will begin to blink). Use this method for cases when the password or IP address
of the NWA is not known.
Use the web configurator to restore defaults (refer to Section 15.7 on page 123).

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 4.1.3 on page 28 for links to more
information on each step.
4.1.1 Choosing the Wireless Mode
•Use Access Point operating mode if you want to allow wireless clients to access your wired
network, all using the same security and Quality of Service (QoS) settings. See Section 1.2.1 on
page 12 for details.
•Use Bridge / Repeater operating mode if you want to use the NWA to communicate with other
access points. See Section 1.2.2 on page 12 for details.
•Use AP + Bridge operating mode if you want to use the NWA as an access point (see above)
while also communicating with other access points. See Section 1.2.3 on page 14 for details.
•Use Wireless Client operating mode if you want to use the NWA to access a wireless network.
See Section 1.2.4 on page 15 for details.
The NWA is a bridge when other APs access your wired Ethernet network through the NWA.
•Use Multi SSID (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 1.2.5 on page 16 for details.

4.2 How to Configure Multiple Wireless Networks
Z
In this example, you have been using your NWA as an access point for your office network (See
your Quick Start Guide for information on how to set up your NWA in Access Point mode). Now your
network is expanding and you want to make use of the Multi-SSID feature (see Multi SSID on page
50) 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 prevents visitors in this network from communicating
with one another.
To do this, you will take the following steps:
1 Edit the SSID profiles.
2 Change the operating mode from Access Point to Multi SSID and reactivate the standard
network.
3 Configure different security modes for the networks.
Chapter 4 Tutorial
4 Configure a wireless network for standard office use.
5 Configure a wireless network for VoIP users.
6 Configure 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.
NWA1100-N User’s Guide

Chapter 4 Tutorial
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 a low QoS
priority and prevents visitors in this network from communicating with one another.
4.2.1 Configure the SSID Profiles
1 Log in to the NWA (see Section 2.1 on page 20). Click Wireless > Multi SSID. The Multi SSID
screen appears.
2 Select the Profile1 radio button and click Edit.
3 Rename the Profile Name as SSID01. Click Save.
4 Repeat Step 2 and 3 to change Profile2 and Profile3 to VoIP_SSID and Guest_SSID.
