Tips for Reading User’s Guides On-Screen
When reading a ZyXEL User’s Guide On-Screen, keep the following in mind:
• If you don’t already have the latest version of Adobe Reader, you can download it from http://
www.adobe.com.
• Use the PDF’s bookmarks to quickly navigate to the areas that interest you. Adobe Reader’s
bookmarks pane opens by default in all ZyXEL User’s Guide PDFs.
• If you know the page number or know vaguely which page-range you want to view, you can
enter a number in the toolbar in Reader, then press [ENTER] to jump directly to that page.
• Type [CTRL]+[F] to open the Adobe Reader search utility and enter a word or phrase. This can
help you quickly pinpoint the information you require. You can also enter text directly into the
toolbar in Reader.
• To quickly move around within a page, press the [SPACE] bar. This turns your cursor into a
“hand” with which you can grab the page and move it around freely on your screen.
• Embedded hyperlinks are actually cross-references to related text. Click them to jump to the
corresponding section of the User’s Guide PDF.

Warnings and Notes
These are how warnings and notes are shown in this User’s Guide.
Warnings tell you about things that could harm you or your NWA.
Note: Notes tell you other important information (for example, other things you may
need to configure or helpful tips) or recommendations.
Syntax Conventions
• The NWA1100-N may be referred to as the “NWA”, the “device”, or the “ZyXEL Device” in this
User’s Guide.
• Product labels, screen names, field labels and field choices are all in bold font.
• A key stroke is denoted by square brackets and uppercase text, for example, [ENTER] means the
“enter” or “return” key on your keyboard.
• “Enter” means for you to type one or more characters and then press the [ENTER] key. “Select”
or “choose” means for you to use one of the predefined choices.
• A right angle bracket ( > ) within a screen name denotes a mouse click. For example,
Maintenance > Log > Log Setting means you first click Maintenance in the navigation panel,
then the Log sub menu and finally the Log Setting tab to get to that screen.
• Units of measurement may denote the “metric” value or the “scientific” value. For example, “k”
for kilo may denote “1000” or “1024”, “M” for mega may denote “1000000” or “1048576” and so
on.
• “e.g.,” is a shorthand for “for instance”, and “i.e.,” means “that is” or “in other words”.
Icons Used in Figures
Figures in this User’s Guide use the following generic icons. The NWA icon is not an exact
representation of your NWA.
Graphics in this book may differ slightly from the product due to differences in operating systems,
operating system versions, or if you installed updated firmware/software for your device. Every
effort has been made to ensure that the information in this manual is accurate.

CHAPTER 1
Introducing the NWA
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.
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:
1Access Point
2Bridge/Repeater
3AP + Bridge
4Wireless Client
5MBSSID
Applications for each operating mode are shown below.

Chapter 1 Introducing the NWA
NWA1100-N User’s Guide

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 (Aand B) are connected to independent wired networks and have a
bridge connection (Acan communicate with B) at the same time. A NWA in repeater mode (Cin
Figure 3) has no Ethernet connection. When the NWA is in bridge mode, you should enable
Spanning Tree Protocol (STP) to prevent bridge loops.
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 6.4.2 on page 65 for more details.
Once the security settings of peer sides match one another, the connection between devices is
made.
