About This User’s Manual
This manual was written for two models:
! PCMCIA Wireless LAN Card
! USB Wireless LAN Card
For brevity, throughout this manual Wireless LAN Card is used to indicate both models.
Also, the following terms/abbreviations are used interchangeably:
! Access Point-AP
! 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 802.11b Wireless LAN PCMCIA/USB adapter. 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
11Mbps. 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 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.

Wireless Network Topologies
The 802.11 standard defines two wireless modes: Infrastructure mode and Ad Hoc mode.
Ad Hoc Network
An Ad Hoc network offers peer to peer connections between wireless stations that are in range
of each other. The stations communicate directly with each other without using an Access
Point or any connection to a wired network. This mode is useful for quickly and easily setting
up a wireless network anywhere that a wireless infrastructure does not exist or is not required
for services. In an Ad Hoc network, all wireless stations must have the same SSID, channel
and WEP keys (if enabled) to communicate with each other.
Figure 1-1 Ad-Hoc Mode

Infrastructure Network
An Infrastructure wireless network consists of at least one Access Point connected to the
wired network infrastructure and a set of wireless end stations. The AP acts as a gateway,
linking the wireless network to a wired LAN. As a result, wireless stations have access to all
of the features of your wired LAN including e-mail, Internet, network printers and files server
access.
Figure 1-2 Infrastructure Mode

Chapter 1 Introduction

Roaming Between Multiple Access Points
For large environments, multiple Access Points can be implemented to extend the wireless
service coverage area for seamless wireless access. It allows wireless clients to roam from one
AP to another while maintaining the wireless connectivity at all times. A wireless client
wandering across multiple APs will automatically change the operating radio frequency as
required.
In a roaming network, all APs and wireless clients must have the same Service Set Identity
(SSID) and security setting (if enabled). Alternatively the mobile station may use an SSID of
“any” to associate with any available AP, regardless of the AP’s SSID. Roaming among
different Access Points is controlled automatically to maintain the wireless connectivity at all
times.

Chapter 2 Installing the Wireless LAN Card
This chapter describes the installation process for the driver and software for the Wireless
LAN Card. Proper driver installation is to allow the device to operate on your host computer
while the utility software, Wireless Client Manager, is to help you configure and monitor your
Wireless LAN Card.
System Requirements
To use the Wireless LAN Card, your computer must meet the following minimum
requirements:
! Windows 98(SE)/Me/2000/XP
! 32 MB of RAM, additional memory recommended
! Standard PCMCIA slot/USB port
! UL listed I.T.E. computers.

Wireless LAN Card Status LEDs
The two LEDs on the Wireless LAN Card indicate connection status and data transfer
operation status described as below:
LED Color State Description
Power Red On The adapter is plugged into the PCMCIA slot/USB port o
f
your computer.
Activity Green Blinking Transmission mode. The faster the LED blinks, the higher
the data exchange rate.
The Antenna on the Wireless LAN Card (Only for Wireless LAN USB Card)
The USB adapter comes with one powerful antenna. You can
rotate the antenna from 0 to 180 degrees to adjust its range and
the connection quality.
Caution: Do not rotate the antenna more than 180 degrees,
otherwise permanent damage may be caused.

Software and Hardware Installation
Caution: Do not connect the Wireless LAN Card device to your computer before installing its
software. If this happens, the Windows PnP function will detect the PCMCIA/USB device and
issue a dialog box requesting its driver. Click Cancel to quit the wizard and unplug the
Wireless LAN Card.
Follow these steps to install the Wireless LAN Card:
1. Close all Windows programs that are running.
2. Insert the provided Software Utility CD into your CD-ROM drive and select
Utility&Driver. Or, run Setup.exe from D:\Utility&Driver folder of the Software
Utility CD where Dis the drive letter. When the welcome screen pops up, click Next.
