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.
Figure 1-1 Ad-Hoc Mode

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.

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 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, Broadcom Wireless Configuration Utility, 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:
 Pentium-class PC,300MHz or better recommended
 64 MB of RAM, additional memory recommended
 Hard disk space at least 30 Mbytes
 Windows 98(SE)/Me/2000/XP
 UL listed I.T.E. computers

Installing Wireless LAN Driver and Software
Follow these steps to install the Wireless LAN Card driver and software:
Caution: Do not connect the Wireless LAN Card device to your computer before installing its driver. If this happens, the Windows PnP function will
detect the wireless adapter and issue a dialog box requesting for its driver. Click Cancel to quit the wizard and unplug the Wireless LAN Card.
1. Close all Windows programs that are running. Insert the provided Software Utility CD into your CD-ROM drive. Run setup.exe from the Driver
folder of the Software Utility CD.
2. If the wireless adapter is not yet inserted into your computer, click Yes. Otherwise click No to remove the device. Then restart your system and
run setup.exe again.

3. When the welcome screen pops up, click Next.
4. Upon hardware detection, Windows OS hardware wizard will appear requesting for the driver. Just follow the on-screen instructions to proceed.
5. Click Finish when the following screen appears.
Now you are done with the installation procedure. The provided Broadcom Wireless Configuration Utility should be launched automatically with its
icon appearing on the right side of the taskbar. Proceed to next chapter to configure or fine-tune your Wireless LAN Card settings.
Note: If you need to set up the TCP/IP address or the subnet mask, refer to “Appendix C Setting Up TCP/IP” for details.

Chapter 3 Using Broadcom Wireless Configuration Utility
Once your wireless adapter software is properly installed, the provided Broadcom Wireless Configuration Utility is ready for use. The utility comes
with six tabs. The Wireless Networks tab allows to configure your wireless connection. The Link Status tab displays the current link status. The Site
Monitor tab allows to monitor available networks. The Diagnostic tab allows to perform diagnostics. The utility information is displayed on the
Information tab. The Statistics tab displays the statistics and status information pertaining to your Wireless LAN Card.
See the ensuing subsections for instructions to launch the utility and description of each tab.
Note: If you are using Windows XP, you can also use the Windows XP-included wireless utility to configure and monitor your wireless network. For
more information on using Windows wireless utility, please refer to Windows XP on-line help.

networks. To connect to an existing network but not appear under Available networks, take the following steps:
1. In Connect to Wireless Network window, click Advanced to launch the Broadcom Wireless Configuration Utility window. Then click Add
under Preferred networks section.
2. In the Wireless Network Properties window, configure the settings below:
Network name (SSID): Specifies the name of the Wireless LAN group you want to participate in.
Network Authentication (Shared mode): Specifies the authentication type. You should use the same setting as the other wireless stations in your
target wireless network.
Wireless network key (WEP): If a network key is required, do the following:
• If the WEP key is automatically provided (for example, the key is stored on the wireless network adapter given to you by your network
administrator), check The key is provided for me automatically check box.
• If the WEP key is not automatically provided for you, leave The key is provided for me automatically check box blank and then enter
the key in the Network key field.

104 bit 13 alphanumeric characters 26 hexadecimal digits
Key index (advanced): Specifies the key index value. You can specify up to four keys (the key index are 0, 1, 2 and 3).
Note: Contact your network administrator if you are unsure about the WEP setting.
Ad Hoc/ Infrastructure Network: If the network you are configuring is an Ad Hoc network, check This is a computer-to-computer (ad hoc)
network… check box. Otherwise leave it unchecked for Infrastructure network connection.
3. After entering required fields, click OK to exit this window.
Your newly configured network will be added under Preferred networks. Your wireless adapter will attempt to connect preferred networks in the
order in which they appear in the list. You can change the order of preferred network by selecting the network that you want to move and clicking the
Move up or Move down button.
Note that in the Preferred networks list, an Ad-hoc network can not be moved to a higher position than an Infrastructure network. If you want to
connect to Ad Hoc network only, see “Specifying a Network Type to Access” for instructions.
