About This Manual

This manual was written for the following types of wireless adapter:

• PC Card

• PCI Card

• Mini PCI Card

For brevity, throughout this manual Wireless LAN Card is used to indicate both types. Also, the following terms/abbreviations are used

interchangeably:

• Access Point – AP

• Peer-to-Peer – Ad Hoc

• Wireless LAN – WLAN

• Ethernet network – LAN – network

This User’s Manual contains information on how to install and configure your Wireless LAN Card. From now on, we will guide you through the

correct configuration steps to get your device up and run.

Chapter 1 Introduction

This Wireless LAN Card is an IEEE 802.11g wireless LAN adapter. 802.11g is the latest in the series of 802.11 specifications for wireless local area

networks (WLANs) and provides data transfer of up to 54 Mbps. Since 802.11g operates on the same frequency of 2.4 GHz as 802.11b, so it is

backwards compatible with existing Wi-Fi devices!

It allows your computer to connect to a wireless network and to share resources, such as files or printers without being bound to the network wires.

Operating in 2.4GHz Direct Sequence Spread Spectrum (DSSS) radio transmission, the Wireless LAN Card transfers data at speeds up to 54Mbps. Both

Ad-Hoc and Infrastructure mode are supported. For network security concern, 64/128-bit Wired Equivalent Protection (WEP) algorithm is used. In

addition, its standard compliance ensures that it can communicate with any 802.11b/g networks.

Wireless LAN Basics

This section conations some Wireless LAN basics to help you better understand how the product work together to create a wireless network.

Local Area Network (LAN)

Simply put, a LAN is a network that exists in a relatively limited area. A network is two or more computers connected together sharing files and

peripheral devices such as printers.

The Wireless LAN Card allows you to interact with other computers without having to run cables normally associated with networks. This lets you

move your computer around while staying connected to your network.

There are two ways to use the Wireless LAN Card. One way is to connect directly to one or more Wireless LAN Card equipped computers, forming an

Ad-Hoc wireless network. The second way is to connect to an Access Point that gives you access to an existing wired LAN, forming an Infrastructure

wireless network.

Ad-Hoc Mode

The Ad-Hoc Group offers peer-to-peer connections between workstations, allowing communication between computers within range that have an

802.11g DSSS compatible PC card installed. A wireless Ad-Hoc network can also access a wired LAN’s TCP/IP service (such as e-mail and the

Internet) by using a TCP/IP software router on an Ethernet equipped PowerBook or notebook.

Chapter 1 Introduction

Infrastructure Mode

The Infrastructure network uses an AP or several APs as a gateway, linking the wireless network to a wired LAN. As a result, portable workstations or

desktops on your wireless network have access to all of the features of your wired LAN including e-mail, Internet access, network printers and files

server.
