1.2 Application Overview

This section describes some network applications for the AG-320.

1.2.1 Station Mode

The AG-320 is in wireless station mode by default. When the AG-320 works as a wireless
station (wireless client), 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 Ad­Hoc mode).

1.2.1.1 Infrastructure

To connect to a network via an access point (AP), set the AG-320 network type to
Infrastructure using the Profile screen. Through the AP, you can access the Internet or the
wired network behind the AP.

1.2.1.2 Ad-Hoc

To set up a small independent wireless workgroup without an AP, use Ad-Hoc.

Ad-Hoc does not require an AP or a wired network. Two or more wireless clients

communicate directly to each other.

ZyXEL AG-320 User’s Guide

1.2.2 Access Point Mode

You can also set the AG-320 to access point mode. In access point mode, your AG-320 allows
you to set up your wireless networks without using a dedicated AP. The following figure
shows a network example.

Figure 4 Application: Access Point Mode

In the example, the AG-320 is installed on computer A and set to operate in access point
mode. Computer A provides an Internet connection to the wireless LAN, so wireless stations
B and C can access the Internet.

Note: With WZC, you cannot use the AG-320 as an access point.

1.2.3 Changing AG-320 Mode

To change between the modes, select either Station Mode or AP Mode in any ZyXEL utility
screens.

Figure 5 ZyXEL Utility: Change Modes

Note: Wait for about five seconds for the ZyXEL utility to complete the mode change.

26 Chapter 1 Getting Started

The current mode is indicated by the color of the check box.

1.3 AG-320 Hardware and Utility Installation

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

1.3.1 ZyXEL Utility Icon

After you install and start the ZyXEL utility, and insert the AG-320, an icon for the ZyXEL
utility appears in the system tray.

Note: The ZyXEL utility system tray icon displays only when the AG-320 is installed

properly.

When you use the ZyXEL utility, it automatically disables WZC.

network.

Configuration Methods

To configure your AG-320, use one of the following applications:

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

• ZyXEL Utility (required when you want to use the AG-320 as an access point)

1.3.2 Enabling WZC

Note: When you use the ZyXEL utility, it automatically disables WZC.

If you want to use WZC to configure the AG-320, you need to disable the ZyXEL utility by
right-clicking the utility icon ( ) in the system tray and selecting Use Windows to configure
my wireless network settings.

Refer to the appendices for information on how to use WZC to manage the AG-320.

To re-activate the ZyXEL utility, double-click the ( ) icon on your desktop or click Start,
(All) Programs, ZyXEL AG-320 Utility, ZyXEL AG-320 Utility GUI.

1.3.3 Accessing the ZyXEL Utility

Double-click on the ZyXEL wireless LAN utility icon in the system tray to open the ZyXEL
utility. The ZyXEL utility screens are similar in all Microsoft Windows versions. Screens for
Windows XP are shown in this User’s Guide.

CHAPTER 2

Tutorial

The following sections show you how to join a wireless network using the ZyXEL utility, as in
the following diagrams. The wireless client is labeled C and the access point is labeled AP.

Figure 8 Infrastructure Network

There are three ways to connect the wireless client (the AG-320 in station mode) to a network.

• 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 2.1 on page 29).

• Configure a profile to have the wireless client automatically connect to a specific network
or peer computer (see Section 2.2 on page 32).

This chapter also includes a simple example of how to configure the AG-320 as an AP using
the ZyXEL utility. See Section 2.3 on page 34 for more information.

2.1 Connecting to a Wireless LAN

This example illustrates how to manually connect your wireless client to an access point (AP)
which is 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 SSID is “SSID_Example3” and the pre-shared key is
“ThisismyWPA-PSKpre-sharedkey” in the AP.

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. When the OTIST screen displays, click No. For information on

the OTIST function, see Section 3.3 on page 41.

2 Click the Site Survey tab to open the screen as shown next.

Figure 10 ZyXEL Utility: Site Survey

3 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 7 on

page 48 for detailed field descriptions.

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

Connect or double-click an entry (with a SSID of SSID_Example3, in this example).

5 When you try to connect to an AP with security configured, a window will pop up

prompting you to specify the security settings. Enter the pre-shared key and leave the
encryption type at the default setting.

Use the Next button to move on to the next screen. You can use the Back button at any
time to return to the previous screen, or the Exit button to return to the Site Survey
screen.
