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.
Figure 1: Types of Networks
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
Page 2 User Guide
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
Page 4 User Guide
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.

FRANCE
Some areas of France have a restricted frequency band for operation in the IEEE 802.11b mode and the IEEE
802.11g mode at 2.4 GHz. The following information describes this restriction. Please check ART's Web site
(http://www.art-telecom.fr) for more up-to-date information.
Autorité de régulation des télecommunications (ART) has made decisions that will allow users to install WLAN
(wireless LAN) systems to provide high-speed Internet services primarily in high-traffic areas (called hot spots).
ART recently released guidelines that establish the conditions for experimenting with the installation of public
WLANs, such as for high-speed Internet access in locations that are currently being poorly served by existing
networks. Such public WLANs would operate in the 2.4-GHz frequency band. This series of measures answers
many of the concerns expressed during Art's public consultation on this topic.
Review Copy
Regulatory Information
Page 18 User Guide
Decisions allowing the installation of wireless terminals in hot spots (train stations, airports, business centers,
and the like): In agreement with the Ministry of Defense, ART has made two decisions setting the conditions
for using wireless LANs in the 2.4-GHz band. One of these decisions has been submitted to the Minister of
Telecommunications for approval. These decisions will allow the installation of WLAN access points to provide
public services in high-traffic public places. This will allow service providers and licensed operators to install
access points using 2.4 GHz band technologies without authorization, under the following technical conditions:
• In 38 départements (see “Metropolitan Departments” on page 19 for listing):
• The 2400–2454 MHz band can be used both indoors and outdoors using systems (access points and
devices) with less than 300 milliwatts (mW) of power.
• The 2454–2483.5 MHz band can be used indoors using devices with less than 100 mW of power and
can be used outdoors using devices with less than 10 mW of power. When the devices are being used
outdoors on private property, the power may be increased to 100 mW after approval from the Ministry
of Defense.
• For the time being, in all other metropolitan départements, the conditions remain unchanged. The list of
the first 38 départements will be progressively added to after 1 January 2003.
• For the overseas départements (DOM), as well as Saint Pierre and Miquelon and Mayotte, the entire
2400–2483.5 MHz band may be used indoors and outdoors using devices with less than 100 mW of
power, except for the Reunion Islands and Guyana, where the 2420–2483.5 MHz band may be used only
outdoors using devices with less than 100 mW of power. ART reminds operators that these frequencies
are used with no guarantee of nondisruption, and that the installations must respect all measures applying
to radio installations (such as urban planning regulations). These decisions also allow the development of
private uses. In particular, private networks (such as indoor corporate networks) can be established using
these technologies.
These conditions are tabulated in Table 2 on page 20.
Guidelines for Public WLAN Experimentation
• Networks using WLAN technology will be granted a free authorization for up to 18 months under article
L.33-1 of the Post and Telecommunications Code. These networks may use systems with 100 mW of
power (effective isotropic radiated power (EIRP)) on the entire band, indoors and outdoors. Moreover, in
the 2.4 GHz band (and providing this power limit is respected), fixed point-to-point links can be
established for these networks needs, or frequencies can be requested in other ad hoc bands.
• Private and public persons may submit applications to ART, provided that legislation and regulations allow
them to do so.
• Applications will be processed in a simplified way, in the spirit of the new "Authorization" Directive.
• ART will send completed applications to the Ministry of Defense. The Ministry will then check that the
projects are not located near any sensitive area and that they are not likely to cause disruptions to military
equipment. For each application, ART will then submit its report and the draft authorization to the Minister
of Telecommunications.
• Applications can be sent from 12 November 2002 so that the first experiments may be launched as soon
as early 2003. Full reviews are to be sent to ART at the end of the temporary authorizations to determine
whether the technology guarantees quality and security to users.

manner that the potential for human contact during normal operation is minimized. To avoid the possibility of
exceeding the FCC radio frequency exposure limits, keep a distance of at least 20 cm between the user (or
any other person in the vicinity) and the antenna that is built into the computer. To determine the location of
the antenna within the notebook, refer to the operating manual for the Integrated 54g enable notebook.
Interference Statement
This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to
Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful
interference in a residential installation. This equipment generates, uses, and can radiate radio frequency
energy. If the equipment is not installed and used in accordance with the instructions, the equipment may
cause harmful interference to radio communications. There is no guarantee, however, that such interference
will not occur in a particular installation. If this equipment does cause harmful interference to radio or television
reception (which can be determined by turning the equipment off and on), the user is encouraged to try to
correct the interference by taking one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the distance between the equipment and the receiver.
• Connect the equipment to an outlet on a circuit different from that to which the receiver is connected.
• Consult the dealer or an experienced radio/TV technician for help.
NOTE—This Integrated 54g enabled notebook must be used in strict accordance with the computer
manufacturer's instructions. Any other installation or use violates FCC Part 15 regulations. Modifications not
expressly approved by the computer manufacturer could void the user's authority to operate the equipment.

Troubleshooting
CANNOT CONNECT TO THE NETWORK
If the Integrated 54g enabled notebook appears to be functioning properly but does not connect to the
network, the problem may be that there is a mismatch between the Network name (SSID) and Wireless
network key (WEP) settings in Wireless Network Properties and the name and WEP key of the network it
is trying to connect to. As explained in "Completing the Setup" on page 3, the network name and WEP key are
case sensitive. Verify that the spelling and case of these parameters are correct and that the settings are
exactly the same on all computers on the network.
If the spelling and case of these parameters are correct and the settings are exactly the same on all computers
on the network, and the computer is still unable to connect to the network, see “Performance and Connectivity
Problems”.
PERFORMANCE AND CONNECTIVITY PROBLEMS
Problem or Symptom Possible Solution
The computers seem to
be communicating, but
they do not appear in
My Computer or in My
Network Places.
Verify that File and Printer Sharing is enabled on all the computers on the network.
1 Click Start, then click Control Panel (Category View).
2 Click Network and Internet Connections.
3 Click Network Connections.
4 Right-click Wireless Network Connections, then click Properties.
5 On the General tab, under This connection uses the following items, verify that
the File and Printer Sharing for Microsoft Networks check box is selected. If the
check box is cleared, select it. If this item is not present, click Install. In the Select
Network Component Type box, select Service and click Add. In the Select
Network Service box, select File and Printer Sharing for Microsoft Networks
and click OK. In Wireless Network Connection Properties, click OK.
Data transfer is
sometimes very slow.
Microwave ovens and some cordless phones operate at the same radio frequency as the
Integrated 54g enabled notebook. When the microwave oven or cordless phone is in use,
it interferes with the operation of the wireless network. Therefore, keep the Integrated 54g
enabled notebook at least 20 feet away from microwave ovens and any cordless telephone
that operates at a frequency of 2.4 GHz.
Data transfer is always
very slow.
Some homes and most offices are steel-framed structures. The steel in such buildings may
interfere with the network's radio signals, thus causing a slowdown in the data transmission
rate. Try moving the Integrated 54g enabled notebook to different locations in the building
to see if performance improves.
Computers are not
communicating with the
network.
If the network has an access point (AP), check all of the cables and make sure the power
LED on the front of the AP is green. Verify that all of the wireless network properties values
are correct. Also, make sure the computer is receiving a good signal from the access point.
The network was
enabled, but now it is
disabled.
The default settings in Microsoft Windows XP Service Pack 1 require IEEE 802.1x
authentication. With IEEE 802.1x authentication enabled, connecting to a network requires
a connection with an authentication server. If the network has no authentication server, the
connection is disabled every 3 minutes. Therefore, when connecting to a network that has
no authentication server, disable IEEE 802.1x authentication by doing the following:
1 Click Start, then click Control Panel (Category View).
2 Click Network and Internet Connections.
3 Click Network Connections.
4 Right-click Wireless Network Connection, then click Properties.
5 Click the Wireless Networks tab.
6 Click the network name under Preferred networks, then click Properties.
7 Click the Authentication tab.
8 Clear the Network access control using IEEE 802.1x check box.
9 Click OK.
