54Mbps 802.11g Wireless LAN Card

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.

Chapter 1 Introduction

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

54Mbps 802.11g Wireless LAN Card

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.

Figure 1-2 Infrastructure Mode

Chapter 1 Introduction

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.

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.
