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 7 Infrastructure Network

There are three ways to connect the wireless client (the AG-120 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 31).

This chapter also includes a simple example of how to configure the AG-120 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.

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