1. Introduction
Welcome to the world of wireless computer networks.
This document is a short reference guide that will show
you how you can:
• Use WLAN Cardbus adapters to connect the mobile
computers to a wireless network.
• Use mobile computers to roam between different
locations without losing the wireless connection.
• Use the wireless network to share files and printers
with other computer users.
In a Local Area Network (LAN), you can connect two or more computers to each
other. You can use a network to share files or common equipment such as a
printer or a modem. In a wired network, you need special cables and networking
equipment to connect the computers, but in a wireless network, computers
communicate via radio technology that can pass through walls and ceilings.
Users connect the wireless computers by assigning a shared Network Name
value to each Wireless Client Adapter that belongs to your network.
To secure your WLAN Cardbus adapter supports Data Encryption when you
transmit data, we recommend that you always enable this feature to protect your
network against unauthorized access to your files and communications.
The WLAN Cardbus adapter support different network modes such as Peer-to-
Peer Group, Act as Base Station, and Base Station Network that allow users to
connect to an existing network or start the network.
For instructions to install your WLAN Cardbus adapter, please consult the
documentation that is included with the hardware.

1.1 The Network Type
Peer-to-Peer Group
Network where Wireless Client devices communicate directly with each other as
the following figure shows.
Act as Base Station
Network where you assign one computer to act as the central point of
communication for all wireless computers. The computer in this mode will start
it's own wireless network. This type of network for SOHO or small offices
provides a larger wireless range than a Peer-to-Peer Group. However you can
assign only one computer to act as Base Station.
Base Station Network
Network where Wireless Client devices communicate with each other through
a dedicated Base Station.

5
With this type of network for medium to large enterprises, you can add as many
Base Station devices as you like to extend the wireless range. Most Base Station
devices also allow you to connect your wireless network to a wired network
infrastructure.

1.2 Using your Wireless LAN
This section provides general information about:
• Configuration Profile to save network settings
• Roaming
• File and Printer Sharing
• Internet Connection Sharing
Using Configuration Profiles
If you plan to use your wireless Client Station in multiple wireless networks, you
can use network configuration profiles to save the settings for each wireless
network.
For example you can create a Configuration Profile for:
• Your office head quarters.
• A branch-office.
• The private home network.
You can use the Configuration Profile to quickly switch between these
networks.
Roaming
Roaming is a key feature of wireless computer networks that you can use to
move with a mobile computer between different locations without losing your
network connection.
In networks that include two or more Base Station devices, the wireless computer
will automatically connect to the Base Station that provides the best quality of
wireless communications.
If users travel between different network environments, they can create a
Configuration Profile for each network and quickly select the right profile to
connect to the other network.
File and Printer Sharing
File and Printer Sharing is a Microsoft Networks feature that allows you to:
• Access files on other computers.
• Print documents on a printer that is connected to another computer.
To use these options, you must enable File and Printer Sharing on the computer
that contains the files or printer connection that you wish to share.
For more information consult the Microsoft Windows Help:
1. Click the Start button.
2. Click Help.

3. Use the Help Search to look for "File and Printer sharing".
Internet Connection Sharing
Internet Connection Sharing is a Microsoft Networks feature that allows multiple
computers to access the Internet via the connection of one computer in your
network. For example, your wireless mobile computer could share the broadband
or dial-up connection of a desktop computer.
To share this connection, you must enable Internet Connection Sharing on the
computer that connects to the Internet.
For more information consult the Microsoft Windows Help:
1. Click the Start button.

1.3 About Client Manager
The Client Manager is a tool that starts automatically every time users boot the
computer. Use the Client Manager to:
• Diagnose the Link Quality of your wireless connection to the network.
• Run Card Diagnostics to verify the operation of the hardware.
• Create or select a wireless Configuration Profile.
• Disable the radio of your Wireless Client Adapter in situations where
local safety guidelines require users to switch of wireless equipment.
To access these functions, click the Client Manager icon on the
taskbar. You can find the icon at the low-right side of your screen.
For more information about color states of the icon or the functions listed above,
please consult the online help of the Client Manager.
Note: The color of the Client Manager icon may differ according to the quality of your
wireless connection. Green means that you have an excellent wireless connection.

1.4 Glossary
Base Station
Base Station devices are also referred to as access points, which allow you to
connect the wireless client to wired computer networks.
Card Diagnostics
Card Diagnostics is a Client Manager option that allows you to perform a
hardware test on your wireless LAN adapter. It allows you to:
• Obtain an online advice on the status of your adapter.
• Generate a report which you can send to your technical support representative
in case you encounter problems using your wireless adapter.
Client Manager
Software tool for Wireless Client Adapter to:
• Manage wireless Configuration Profile settings
