type and use the same SSID, channel and security.

1.5 G-162 Hardware and Utility Installation

Follow the instructions in the Quick Start Guide to install the ZyXEL Utility and make hardware connections. The ZyXEL Utility is a program that lets you configure wireless parameters in the G-162. These parameters must be the same as the access point (AP) or peer WLAN device that you are connecting with.

1.6 Configuration Methods

To configure your G-162, use one of the following applications:

¾ ZyXEL Utility (This guide shows you how to configure the G-162 using the ZyXEL Utility) ¾ Wireless Zero Configuration (WZC) (recommended for Windows XP)

In Windows XP, you must disable WZC if you want to use the ZyXEL Utility. Refer

to the appendices on how to deactivate WZC or how to use WZC to manage the

G-162.

¾ Odyssey Client Manager (not supplied)

Refer to the Odyssey Client documentation for more information.

Chapter 2

Link Info

This chapter shows you detailed information about the Link Info screen.

2.1 Transmission Rate (Transfer Rate)

The G-162 provides various transmission (data) rate options for you to select. Options include Fully Auto, 1 Mbps, 2 Mbps, 5.5 Mbps, 11 Mbps, 6 Mbps, 9 Mbps, 12 Mbps, 18 Mbps, 22 Mbps, 24 Mbps, 36 Mbps, 48 Mbps, 54 Mbps and 125 Mbps.

In most networking scenarios, the factory default Fully Auto setting is the most efficient. This setting allows your G-162 to operate at the highest possible transmission (data) rate. When the communication quality drops below a certain level, the G-162 automatically switches to a lower transmission (data) rate. Transmission at lower data speeds is usually more reliable. However, when the communication quality improves again, the G-162 gradually increases the transmission (data) rate again until it reaches the highest available transmission rate.

If you want to select a specific transmission rate, select one that the AP or peer wireless device supports. 1 Mbps or 2 Mbps are often used in networking environments where the range of the wireless connection is more important than speed.

Your G-162 can transmit at 22Mbps or up to 125 Mbps when connected to a

ZyXEL g+ AP or wireless router.

Actual speeds attained also depend on the distance from the AP, noise, etc.

2.1.1 G-plus

G-plus is an enhancement to the IEEE 802.11g wireless standard. G-plus combines multiple frames into a larger frame size. This increases wireless transmission speeds by allowing larger frames (up to 4 KB) to be sent.

G-plus speed applies only to unicast traffic (not broadcast or multicast). G-plus is automatically disabled if wireless transmission speeds fall below 11 Mbps.

2.2 Configuring the Link Info screen

When the ZyXEL Utility starts, the Link Info screen displays, showing the current configuration and connection status of your G-162. You can also click the Link Info tab to display the screen as shown next.

Wireless LAN security is vital to protect wireless communications.

The figure below shows the possible wireless security levels on your G-162. EAP (Extensible Authentication Protocol) is used for authentication and utilizes dynamic WEP key exchange. It requires interaction with a RADIUS (Remote Authentication Dial-In User Service) server either on the WAN or your LAN to provide authentication service for wireless clients.

Configure the wireless LAN security using the Profile Security Settings screen. If you do not enable any wireless security on your G-162, the G-162’s wireless communications are accessible to any wireless networking device that is in the coverage area.

4.1.1 Data Encryption with WEP

WEP (Wired Equivalent Privacy) encryption scrambles all data packets transmitted between the G-162 and the AP or other peer wireless device to keep them private. Both the wireless clients and the access points must use the same WEP key for data encryption and decryption.

There are two ways to create WEP keys in your G-162.

• Automatic WEP key generation based on a “password phrase” called a passphrase. The passphrase

is case sensitive. You must use the same passphrase for all WLAN adapters with this feature in the same WLAN.
