1.1.1 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.

1.1.2 Before You Begin

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

utility to connect your NWD2705 to a network.

1.2 About Your NWD2705

Your NWD2705 is an IEEE 802.11n compliant wireless LAN adapter. It can also connect to IEEE

802.11b/g wireless networks. The NWD2705 is WPS (Wi-Fi Protected Setup) compliant. WPS allows

you to easily connect to another WPS-enabled device.

The NWD2705 is a USB adapter which connects to an empty USB port on your computer.

See your NWD2705’s Quick Start Guide for installation instructions, and see the section on product

specifications in this User’s Guide for detailed information.

1.4 Hardware and Utility Installation

Follow the instructions in the Quick Start Guide to install the ZyXEL utility and make hardware

connections.

1.4.1 ZyXEL Utility Icon

After you install and start the ZyXEL utility, an icon for the ZyXEL utility appears in the system tray.

Note: The ZyXEL utility system tray icon displays only when the NWD2705 is installed

properly.

Chapter 1 Getting Started

NWD2705 User’s Guide

14

Note: When you use the ZyXEL utility, it automatically disables Wireless Zero

Configuration (WZC) in Windows XP.

Figure 3 ZyXEL Utility: System Tray Icon

The color of the ZyXEL utility system tray icon indicates the status of the NWD2705. Refer to the

following table for details.

1.5 Configuration Methods

To configure your NWD2705, use one of the following applications:

• Wireless Zero Configuration (WZC, the Windows XP wireless configuration tool) or WLAN

AutoConfig (the Windows Vista wireless configuration tool).

• The ZyXEL utility.

Note: Do NOT use Windows XP’s Wireless Zero Configuration tool at the same time you

use the ZyXEL utility.

1.5.1 Enabling Windows Wireless Configuration

Note: When you use the ZyXEL utility, it automatically disables Windows XP’s wireless

configuration tool.

If you want to use the Windows XP wireless configuration tool to configure the NWD2705, you need

to disable the ZyXEL utility. Right-click the utility icon ( ) in the system tray and select Exit.

Figure 4 Enable WZC

Refer to the appendices for information on how to use the Windows wireless configuration tool to

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 5 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

17 for details.

• Connect securely to an infrastructure AP using many of the strongest and most common

encryption protocols. See Section 2.3 on page 20 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 22 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 NWD2705’s features and

hardware, as described in Chapter 1 on page 11.

• 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.

Chapter 2 Tutorial

NWD2705 User’s Guide

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 NWD2705 as the wireless client, and ZyXEL’s NBG4615 v2 as the Access Point (AP).

Note: 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 17.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 NWD2705’s interface. See Section 2.2.2 on page 18. 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

NWD2705 installed.

2 Make sure that you have installed the NWD2705’s driver and utility on your computer.

3 In the NWD2705’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 NBG4615 v2, press

the Push Button button in the Network > Wireless LAN > WPS Station screen.

Note: 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 NWD2705. This may take up to two minutes.

Then the NWD2705 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 NBG4615 v2 in this example) and the NWD2705.

Figure 6 Example WPS Process: PBC Method

2.2.2 PIN Configuration

When you use the PIN configuration method, you need to use both the NWD2705’s utility and the

AP’s configuration interface.

1 In the NWD2705’s Adapter 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 NBG4615 v2, use the PIN field in

the Network > Wireless LAN > WPS Station screen.

3 Click the Start buttons on both the NWD2705 utility screen and the AP’s configuration utility (the

WPS Station screen on the NBG4615 v2) within two minutes.

The NBG4615 v2 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 NBG4615 v2 securely.

2.3 Connecting to an AP Without Using WPS

There are three ways to connect the wireless client (the NWD2705) to a network without using

WPS.

• Configure nothing and leave the wireless client to automatically scan for and connect to any

available network that has no wireless security configured.

• Manually connect to a network (see Section 2.3.1 on page 20).

• Configure a profile to have the wireless client automatically connect to a specific network or peer

computer (see Section 2.3.2 on page 22).

2.3.1 Manually Connecting to a Wireless LAN

This example illustrates how to manually connect your wireless client to an access point (AP)

configured for WPA-PSK security and connected to the Internet. Before you connect to the access

point, you must know its Service Set IDentity (SSID) and WPA-PSK pre-shared key. In this

example, the AP’s SSID is “SSID_Example3” and its pre-shared key is “ThisismyWPA-PSKpre-

sharedkey”.

After you install the ZyXEL utility and then insert the wireless client, follow the steps below to

connect to a network using the Site Survey screen.

1 Open the ZyXEL utility and click the Site Survey tab to open the screen shown next.

Figure 8 ZyXEL Utility: Site Survey

2 The wireless client automatically searches for available wireless networks. Click Scan if you want to

search again. If no entry displays in the Available Network List, that means there is no wireless

network available within range. Make sure the AP or peer computer is turned on, or move the

wireless client closer to the AP or peer computer. See Table 4.4 on page 39 for detailed field

descriptions.

3 To connect to an AP or peer computer, either click an entry in the list and then click Connect or

double-click an entry (SSID_Example3 in this example).
