CHAPTER 1
Getting Started
1.1 Overview
The ZyXEL NWD-270N Wireless N-lite USB Adapter adapter brings you a better Internet
experience over existing 802.11 networks. With data rates of up to 150 Mbps, you can enjoy a
breathtaking high-speed connection at home or in the office. It is an excellent solution for
daily activities such as file transfers, music downloading, video streaming and online gaming.
This section includes:
• About Your NWD-270N on page 22
• Application Overview on page 23
• Hardware and Utility Installation on page 24
• Configuration Methods on page 25
1.1.1 What You Need to Know
The following terms and concepts may help as you read through this sectio n, and subsequently
as you read through the rest of the User’s Guide.
Access Point
An Access Point (AP) is a network device that acts as a bridge between a wired and a wireless
network. Outside of the home or office, APs can most often be found in coffee shops,
bookstores and other businesses that offer wireless Internet connectivity to their customers.
Infrastructure
An infrastructure network is one that seamlessly combines both wireless and wired
components. One or more APs often serve as the bridge between wireless and wired LANs.
Ad-Hoc
An Ad-Hoc wireless LAN is a self-contained group of computers connected wirelessly and
which is independent of any other networks and Access Points.
1.1.2 Before You Begin
• Read the Quick Start Guide for information on making hardware connections and using
the ZyXEL utility to connect your NWD-270N to a network.
NWD-270N User’s Guide

Chapter 1 Getting Started
1.2 About Your NWD-270N
Your NWD-270N is an IEEE 802.11n draft 2.0 compliant wireless LAN adapter. It can also
connect to IEEE 802.11b/g wireless networks. The NWD-270N is WPS (Wi-Fi Protected
Setup) compliant. WPS allows you to easily connect to another WPS-enabled device.
The NWD-270N is a USB adapter which connects to an empty USB port on your computer.
See your NWD-270N’s Quick Start Guide for installation instructions, and see the section on
product specifications in this User’s Guide for detailed information.
1.2.1 Hardware
This section describes the NWD-270N’s physical appearance.

1.3 Application Overview
This section describes some network applications for the NWD-270N. You can either set the
network type to Infrastructure and connect to an AP or use Ad-Hoc mode and connect to a
peer computer (another wireless device in Ad-Hoc mode).
1.3.1 Infrastructure
To connect to a network via an access point (AP), set the NWD-270N network type to
Infrastructure (see Chapter 4 on page 59). Through the AP, you can access the Internet or the
wired network behind the AP.
Figure 2 Application: Infrastructure
Chapter 1 Getting Started
1.3.2 Ad-Hoc
To set up a small independent wireless workgroup without an AP, use Ad-Hoc (see Chapter 4
on page 59).
Ad-Hoc does not require an AP or a wired network. Two or more wireless clients
communicate directly with each other.
" Wi-Fi Protected Setup (WPS) is not available in ad-hoc mode.

Tutorial
2.1 Overview
This tutorial shows you how to join a wireless infrastructure network using the ZyXEL utility .
The wireless client is labeled C and the Access Point is labeled AP.
Figure 6 Infrastructure Network
2.1.1 What You Can Do in This Tutorial
• Connect securely either to an infrastructure AP using the WPS protocol. See Section 2.2
on page 28 for details.
• Connect securely to an infrastructure AP using many of the strongest and most common
encryption protocols. See Section 2.3 on page 31 for details.
• Save a your settings so that you can later connect again to an infrastructure AP with a
single click. See Section 2.3.2 on page 33 for details.
2.1.2 What You Need to Know
The following term may help as you read through this section.
WPS
Wi-Fi Protected Setup (WPS) is a security protocol that lets two or more devices connect
securely to one another with a minimum amount of hassle on your part. It most cases,
establishing a secure connection with another WPS device is as easy as pushing a button.
2.1.3 Before You Begin
• Make sure that you have already familiarized yourself with the NWD-270N’s features and
hardware, as described in Chapter 1 on page 21.
• You should have valid login information for an existing network Access Point, otherwise
you may not be able to make a network connection right away.

2.2 Connecting to an AP using Wi-Fi Protected Setup (WPS)
This section gives you an example of how to set up your wireless network using WPS. This
example uses the NWD-270N as the wireless client, and ZyXEL’s NBG334W as the Access
Point (AP).
" The Access Point must be a WPS-aware device.
There are two WPS methods for creating a secure connection. This tutorial shows you both.
• Push Button Configuration (PBC) - create a secure wireless network simply by pressing
a button. See Section 2.2.1 on page 28.This is the easier method.
• PIN Configuration - create a secure wireless network simply by entering a wireless
client's PIN (Personal Identification Number) in the NWD-270N’s interface. See Section
2.2.2 on page 29. This is the more secure method, since one device can authenticate the
other.
2.2.1 Push Button Configuration (PBC)
1 Make sure that your access point is turned on and that it is within range of the computer
with the NWD-270N installed.
2 Make sure that you have installed the NWD-270N’s driver and utility on your computer.
3 In the NWD-270N’s utility, click the Adapter tab, enable WPS and select PBC (Push
Button Configuration). In the screen that appears, click Start.
4 Log into the AP’s web configurator and locate its WPS settings section. On the
NBG334W, pres s the Push Button button in the Network > Wireless Client > WPS
Station screen.
" It doesn’t matter which button is pressed first. You must press the second
button within two minutes of pressing the first one.
The AP sends the proper configuration settings to the NWD-270N. This may take up to two
minutes. Then the NWD-270N is able to communicate with the AP securely.
The following figure shows you an example to set up wireless network and security by
pressing a button on both the AP (the NBG334W in this example) and the NWD-270N.

2.2.2 PIN Configuration
When you use the PIN configuration method, you need to use both the NWD-270N’s utility
and the AP’s configuration interface.
1 In the NWD-270N’s Adaptor tab, select WPS and PIN - Use this Device’s PIN. Note
down the PIN in the screen that appears.
2 Enter the PIN number in the AP’s configuration interface. In the NBG334W, use the
PIN field in the Network > Wireless LAN > WPS Station screen.
3 Click the Start buttons on both the NWD-270N utility screen and the AP’s configuration
utility (the WPS Station screen on the NBG334W) within two minutes.
The NBG334W authenticates the wireless client and sends the proper configuration settings to
the wireless client. This may take up to two minutes. Then the wireless client is able to
communicate with the NBG334W securely.
The following figure shows you the example of configuring the wireless network and security
on the NWD-270N and the AP (ZyXEL’s NBG334W in this example) by using the PIN
method.
