Introduction

THE INTEGRATED 54g SOLUTION

The Integrated 54g solution accesses wireless local area networks (WLANs), enables the sharing of a local printer and files with others in the network, enables Internet connection sharing, and enables roaming about the office—wire free. This wireless LAN solution is designed for both the home user and small businesses— and it is scalable so that users can be added and new network features can be enabled as networking needs grow.
The WEP (Wired Equivalent Privacy) protocol is a security protocol for wireless local area networks (defined in IEEE Std 802.11, 1999 Edition) that encrypts data sent over radio waves. The use of the WEP key is optional and can be enabled or disabled. If the network being connecting to has enabled WEP, WEP must also be enabled in the network profile and the WEP key in the computer must be set to match the WEP key used by the network. Otherwise, it is impossible to connect to the network.
The Integrated 54g enabled notebook makes a wireless connection to a network, as illustrated on the following figure. Upon startup, the Integrated 54g enabled notebook detects certain WLANs (wireless networks) that are within range. Before connecting to these and other wireless networks, a user must configure a profile for each network. See "Completing the Setup" on page 3.
Networks 1 and 2 are infrastructure types of networks. The two notebook computers connected by radio waves form an ad hoc type of network.

ENTERPRISE USERS

Obtain the following information from the network administrator:
• Network names (SSID) of the specific wireless networks to connect to
• WEP (Wired Equivalent Privacy) key information (if any) for the networks to connect to
• For Microsoft Windows networking, the customer name and workgroup name
• For a network account, a user name and password
• An IP address (if not using a DHCP server)
• If any of the networks are connected to an authentication server

Introduction

HOME USERS

The AP (access point) that communicates with the Integrated 54g enabled notebook has a preassigned network name (SSID) that the notebook recognizes upon startup. To enable WEP, use any string of numbers for the WEP key.

USING THE INTEGRATED 54g ENABLED NOTEBOOK

The Integrated 54g enabled notebook is an IEEE 802.11g based wireless LAN device. A LAN is composed of two or more computers that are connected to each other to share files or common equipment such as a printer or an Internet connection. A wireless LAN provides the same functionality of a wired network, but it eliminates the need to install networking cables and other networking equipment. Not only is a wireless LAN easier to deploy, but it also allows for roaming. For example, when using the Integrated 54g enabled notebook, it is possible to roam from one room in the house to another, or from a conference room to an office without being disconnected from the network.

FEATURES AND REQUIREMENTS

The Integrated 54g solution is an IEEE 802.11 based wireless LAN that includes the following features:
• Support for IEEE 802.11g draft specification
• Support for IEEE 802.11b standard
• 2.4-GHz band operation
• Network data rate of up to 54 Mbit/s
• Wired Equivalent Privacy (WEP) encryption
The following items are needed for participating in a wireless LAN:
• Integrated 54g enabled notebook computer running on a Microsoft Windows XP operating system
• Software drivers, software reference guide, and Help file
The Integrated 54g enabled notebook works with any IEEE 802.11b Wi-Fi CERTIFIED or IEEE 802.11g access point or wireless client network adapter.

Completing the Setup

NOTE—Before starting, obtain the required network information from the network administrator or the wireless access point installer (see “The Integrated 54g Solution” on page 1).

MODES OF OPERATION

A wireless LAN can be configured for two different modes of operation: infrastructure mode and ad hoc mode (an ad hoc network is also known as a peer-to-peer network or a computer-to-computer network). Whereas each mode has its advantages, one mode may be more appropriate than the other, depending on the location and type of network connection.

INFRASTRUCTURE MODE

The key difference between the infrastructure type of network and an ad hoc network is that the infrastructure network includes a base station (host) computer that has a built-in wireless network adapter and is connected to a wireless access point (AP). This functionality allows computers on the infrastructure wireless LAN to access the resources and tools of the wired LAN, including Internet access, e-mail, file sharing, and printer sharing.
Characteristics
Networked computers communicate with each other through a dedicated AP. All data transmitted between the computers on this wireless LAN passes through the AP.
Advantages
• Extended range. The access point extends the range of the wireless LAN. Each computer can
communicate with other computers equipped by wireless networks that are within the range of the access point.
• Roaming. As the user moves around the home or office, the Integrated 54g enabled notebook
determines the best access point to use to ensure continuous communication with the network.
• Network connectivity. An access point can provide wireless LAN access to an existing wired network by
bridging the two networks together. This gives users of the wireless LAN access to all the functions of a wired network—from file server access to access to e-mail and the Internet.
Disadvantages
Because the infrastructure mode offers more features, it requires additional components and setup time to deploy.
Requirements
• A base station computer having a wired connection to the Internet
• A wireless network adapter
• A connection to an AP (access point)

Completing the Setup

AD HOC MODE

An ad hoc network is the easiest to deploy and is ideal for home use or in small offices. This mode allows the sharing of files with other employees, printing to a shared office printer, and access to the Internet through a shared modem. With ad hoc networking, however, the computer is only able to communicate with other wireless networks that are within a certain range and are in the same wireless workgroup.
Characteristics
Networked computers send data directly to each other without the need of an access point.
Advantages
• Simple setup
• Cost efficiency
Disadvantages
• Communication is limited to those who are located within a certain range.
• IEEE 802.1x security is not available.
Requirements
There are no other equipment requirements for operating in the ad hoc mode besides 2 WLAN enabled notebooks or desktop PCs.

CONFIGURING A NETWORK PROFILE

To connect to a wireless network, a network profile for that network must be configured on the Integrated 54g enabled notebook. If the Integrated 54g enabled notebook computer came with the Integrated 54g network adapter already installed and set up at the factory, follow the network profile configuration instructions provided below.
NOTE—For more information on how to configure a network profile and IEEE 802.1x authentication, click
Learn about setting up wireless network configuration on the Wireless Networks tab of Wireless Network Connection Properties.
You can configure a network profile for networks that are listed under Available networks as well as those that are not listed. When you have completed configuring a network profile, the network name and icon appear at the top of the list under Preferred networks. The computer automatically connects to the network at the top of the list. Follow the applicable instruction set below, based on whether or not the network is listed, whether or not the network requires a WEP key, and whether or not the network is connected to an authentication server (check with the network administrator to see if a WEP key is required and if the network is connected to an authentication server).
NOTE—Both the network name and the network key are case-sensitive.
