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.
This User’s Manual contains information on how to install and configure your Wireless LAN
Card. Your Wireless LAN Card will allow you to connect your computer to other Wireless
LAN Card equipped computers.

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 Network
The Ad Hoc network offers peer to peer connections between workstations, allowing
communication between computers within range that have an 802.11b 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.
Infrastructure Network
The infrastructure network uses an access point (or several access points) 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.
Roaming
Multiple Access Points can be installed to extend the wireless service coverage area for
seamless wireless access. Within an extended service area, all Access Points and wireless
clients must have the same Service Set Identity (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 system requirement and Wireless LAN Card status LEDs. In
addition, we will guide you through the Wireless LAN Card installation as outlined below:
For Windows 98(SE)/Me/2000
1. Installing the software utility using the provided Software Utility CD.
2. Installing the hardware and then driver installation will be auto-processed.
For Windows XP
Installing the hardware and then manually install the driver upon hardware detection.
Note: When connecting the hardware, note that this Wireless LAN Card is for use with UL
listed I.T.E. computers.
After completing the steps above, if you need to set up the TCP/IP protocol to communicate
with your network, refer to “Appendix C Setting Up TCP/IP” on page 61 for details.

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
Wireless LAN Card Status LEDs
The two LEDs on the Wireless LAN Card indicate connection status and data transfer
operation status, as described 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.
Note: Do not rotate the antenna more than 180 degrees, otherwise permanent damage may be
caused.
Installing the Wireless LAN Card Software
Note: If you are using Windows XP, the operation system is already equipped with Wireless
LAN Card Software, so you don’t have to install extra software but only need to install the
driver to activate the Wireless LAN Card. Please skip this step and go to next section
“Installing the Hardware”.
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.
Follow these steps to install the Wireless LAN Card software:
1. Close all Windows programs that are running.
