CHAPTER 1

Getting Started

1.1 Overview

The ZyXEL NWD Series of dual-band wireless USB adapters can connect to a 2.4 G network or a 5G

network and bring you a better Internet experience over existing 802.11 networks.

This section includes an overview of your NWD Series adapter.What You Need to Know

The following terms and concepts may help as you read through this section, 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.

1.1.1 Before You Begin

Read the Quick Start Guide for information on making hardware connections and using the ZyXEL utility

to connect your NWD Series to a network.

1.2 About Your NWD Series Wireless LAN Adapter

Your NWD Series IEEE 802.11ac compliant wireless LAN adapter can also connect to IEEE 802.11 a/b/g/n/

ac wireless networks. The NWD Series’ WPS (Wi-Fi Protected Setup) allows you to easily connect to

another WPS-enabled device.

The NWD Series of USB adapters connect to an empty USB port on your computer.

See your NWD Series’s Quick Start Guide for installation instructions, and see the section on product

specifications in this User’s Guide for detailed information.

CHAPTER 2

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 3 Infrastructure Network

2.1.1 What You Can Do in This Tutorial

• Install the driver for your NWD Series adapter. See Section 2.2 on page 11 for details.

• Connect securely to an infrastructure AP using your adapter’s Connection Wizard. See Section 2.3.1

on page 14 for details.

• Connect securely to an infrastructure AP using the WPS protocol. See Section 2.3.2 on page 17 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 Series’s features and hardware,

as described in Chapter 1 Getting Started.

• 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.

Note: In the following procedures the NWD6605 driver installation tool and Windows 7 OS are

used for purposes of example.

CHAPTER 3

Wireless LANs

3.1 Overview

This section provides background information on wireless Local Area Networks.

3.1.1 What You Need to Know

The following terms and concepts may help as you read through this section.

Server

When two or more devices are connected digitally to form a network, the one that distributes data to

the other devices is known as the “server”. A RADIUS (Remote Authentication Dial-In User Service) is a

kind of server that manages logins and logout, among other things, for the network to which it is

connected.

Client

When two or more devices are connected digitally to form a network, the one that contacts and

obtains data from a server is known as the “client”. Each client is designed to work with one or more

specific kinds of servers, and each server requires a specific kind of client. Wireless adapters are clients

that connect to a network server through an AP.

3.2 Wireless LAN Overview

The following figure provides an example of a wireless network with an AP.

Chapter 3 Wireless LANs

NWD Series User’s Guide

Figure 8 Example of a Wireless Network

The wireless network is the part in the blue circle. In this wireless network, devices A and B are called

wireless clients. The wireless clients use the access point (AP) to interact with other devices (such as the

printer) or with the Internet

Every wireless network must follow these basic guidelines.

• Every device in the same wireless network must use the same SSID.

The SSID is the name of the wireless network. It stands for Service Set IDentity.

• If two wireless networks overlap, they should use a different channel.

Like radio stations or television channels, each wireless network uses a specific channel, or frequency,

to send and receive information.

• Every device in the same wireless network must use security compatible with the AP or peer

computer.

Security stops unauthorized devices from using the wireless network. It can also protect the

information that is sent in the wireless network.

3.3 Wireless LAN Security

Wireless LAN security is vital to your network to protect wireless communications.

If you do not enable any wireless security on your NWD Series, the NWD Series’s wireless communications

are accessible to any wireless networking device that is in the coverage area.
