device up and run.
IV
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
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.

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
