CHAPTER 1

Getting Started

This chapter introduces the AG-120 and prepares you to use the ZyXEL utility.

1.1 About Your AG-120

The AG-120 is an IEEE 802.11a/b/g compliant wireless LAN adapter. You can also use the ZyXEL utility to turn your AG-120 into an access point (AP). The ZyXEL utility is a tool that helps you configure your AG-120. See the appendix for detailed product specifications.

1.2 Application Overview

This section describes some network applications for the AG-120.

1.2.1 Station Mode

The AG-120 is in wireless station mode by default. When the AG-120 works as a wireless station (wireless client), you can either set the network type to Infrastructure and connect to an AP or use Ad-Hocmode and connect to a peer computer (another wireless device in Ad- Hoc mode).

1.2.1.1 Infrastructure

To connect to a network via an access point (AP), set the AG-120 network type to Infrastructure using the Profile screens. Through the AP, you can access the Internet or the wired network behind the AP.
