Types of Wireless LANs Covered by this Document

This document is applicable to systems containing one

of the following two wireless modules. Most of the

procedures are identical. Sections that differ between the

two devices have been noted in the text:

Intel PROSet Wireless LAN

Atheros Wireless LAN

If your system is a T3010 model, your wireless module

Characteristics of the Wireless Module

This wireless module is a mini-PCI card attached to a

mini-PCI slot inside the computer.

The main characteristics are as follows:

It operates in the 2.4 GHz Industrial, Scientific, and

Medical (ISM) RF band; additionally, the Atheros

wireless LAN operates in the 5 GHz RF band.

It does not require an FCC license to operate.

It uses Direct Sequence Spread Spectrum (DSSS), an

RF modulation scheme that is resistant to noise.

This wireless module is Wi-Fi compliant. The Intel

PROSet module can communicate at a maximum data

rate of 11 Mbps; the Atheros module can communi-

cate at the maximum data rate of 54 Mbps.

The maximum communication range is approxi-

mately 80 feet (25 meters) inside a building. Please

note that the range you achieve may be shorter or

longer than 80 feet, depending on factors such as

obstructions, walls, columns, construction material,

and reflective objects.

The wireless modules support a number of industry-

standard security mechanisms, including WEP, TKIP,

and 802.1x/EAP (LEAP, TLS, PEAP, MD5).

Wireless LAN Modes Using this Wireless Module

Ad Hoc Mode (See Figure A-1)

“Ad Hoc Mode” refers to a type of wireless network that

involves connecting multiple computers without the use

of an Access Point. Network connectivity between

computers can be established using only wireless LAN

cards in a peer-to-peer fashion.

Ad Hoc networks are an easy and inexpensive method

for establishing network connectivity between multiple

computers.

In Ad Hoc mode, you can use Microsoft Network func-

tions, such as File and Print Sharing to share folders,

printers, or other peripheral devices, and exchange files

with other computers.

To use Ad Hoc Mode, you must set the same SSID and

the same encryption key for all the computers that are

connected. Communication between computers in an

Ad Hoc network will occur provided they are within

each other’s RF coverage area.

Figure A-1. Ad Hoc Mode Network

available for Fujitsu mobile computers. This manual

describes the basic operating prodecures for the

Wireless LAN (referred to as the "wireless module" in

this manual) and how to set up a wireless LAN network.

Before using this wireless module, read this manual

carefully to ensure correct operation of the device. Keep

this manual in a safe place for reference while using the

wireless module.

is the Intel PROSet wireless LAN; if your system is a

T3010D model, your wireless module is the Atheros

wireless LAN.

Wireless LAN User’s Guide

Access Point (Infrastructure) Mode (See Figure A-2)

If a number of computers are connected simultaneously

in the Ad Hoc mode, the transfer rate may be reduced,

communications may become unstable, or the network

connection could fail. This is because all wireless LAN

cards are using the same radio frequency in the network.

To improve this situation, you can use a wireless LAN

access point, which is sold separately. The wireless LAN

network is in the “Access Point mode” when it uses an

access point, and such a connection is called the “Access

Point Network” or “Infrastructure Network”.

By using an access point, you can set and use a different

communication channel for each network group. Each

channel is given a different radio frequency, and it

eliminates the collision of communications and provides

a more stable communications environment.

How to Handle This Wireless Module

The Integrated Wireless LAN device is already installed in

your mobile computer. Under normal circumstances, it

should not be necessary for you to remove or re-install it.

The wireless LAN has been configured to support the

operating system with which your system shipped.

FOR BETTER COMMUNICATIONS

This personal computer may not operate properly due to

the operating environment. It is highly recommended

that you observe the following precautions when using

your wireless LAN module:

■For optimum wireless communications, it recom-

mended that operation of the wireless LAN module

occur within 25 meters of the Access Point. Wireless

range is dependent on a multitude of factors including

number of obstructions, walls, type of construction

material, reflective objects, etc.

■If the computer is unable to communicate properly,

change the channel to be used or the installation loca-

tion. During the use of a microwave oven or other

equipment generating strong high-frequency energy, in

particular, the personal computer may be highly sus-

ceptible to the energy and unable to communicate

properly.

■Broadcast stations or wireless communication equip-

ment that operate in the 2.4GHz or 5GHz RF Fre-

quency band may interfere with the operation of the

wireless LAN module. Increasing of transmit power or

relocating Access Points may be necessary to combat

the effects of the interference.

Troubleshooting

Causes and countermeasures for troubles you may encounter while using your wireless LAN are described in the

following table.

Problem Possible Cause Possible Solution

Unavailable

network

connection

Incorrect network

name (SSID) or

network key

Ad hoc connection: verify that the network names (SSID’s) and network

keys (WEP) of all computers to be connected have been configured

correctly. SSID’s and WEP key values must be identical on each machine.

Access Point (Infrastructure) connection: set the network name (SSID)

and network key to the same values as those of the access point.

Set the Network Authentication value identically to that of the Access

Point. Please consult your network administrator for this value, if

necessary.

For the method of setting network authentication, refer to the following

pages:· “ Assigning parameters” on page 55·

Poor radio wave

condition Ad hoc connection: Retry connection after shortening the distance to

the destination computer or removing any obstacles for better sight.

Access Point (Infrastructure) connection: Retry connection after short-

ening the distance to the access point or removing any obstacles for

better sight.

To check the wave condition, refer to the following pages:· “ Confirming

the status of the radio waves” on page 59.·

Radio wave

transmission has

stopped

Check if the wireless switch is turned ON. Also verify “ Disable Radio” is

not checked in “ Network setting” window. Refer to “ Starting Transmis-

sion” on page 54.

The computer to be

connected is turned

off

Check if the computer to be connected is turned ON.

Active channel

duplication due to

multiple wireless

LAN networks

If there is any other wireless LAN network nearby, change channels to

avoid active channel duplication. For the method of checking active

channels, refer to the following pages:· “ Confirming the status of the

radio waves” on page 59·

No right of access to

the network to be

connected

Check if you have a right of access to the network to be connected with.

Incorrectly-

performed network

Wireless LAN Glossary

Access point

A designation of wireless LAN network configurations.

It indicates a form of communication using an Access

Point. For details, refer to “access point connection” on

page52.

Ad hoc

A designation for wireless LAN network configuration.

It indicates a form of communication limited to those

personal computers which have wireless LAN function.

For details, refer to “Ad hoc connection” on page52.

Channel

The frequency band of wireless LAN to be used in

communications over wireless LAN or at the access

point.

DHCP (Dynamic Host Configuration Protocol)

A protocol used for automatically fetching communica-

tion parameters such as IP addresses. The side which

assigns IP address is called DHCP server and the side

that is assigned it is called DHCP client.

DNS (Domain Name System)

A function that controls the correspondence of IP

addresses assigned to a computer with the name. Even

for those computers whose IP addresses are unknown, if

their names are known, it is possible to communicate

with them.

IEEE802.11a

One of the wireless LAN standards prescribed by the

802.11 committee in charge of establishing standards of

LAN technology in IEEE (Institute of Electrical and

Electronic Engineers). It allows communications at the

maximum speed of 54 Mbps by using a 5GHz band

which can freely be used without radio communication

license.

IEEE802.11b

One of the wireless LAN standards prescribed by the

802.11 committee in charge of establishing standards of

LAN technology in IEEE (Institute of Electrical and

Electronic Engineers). It allows communications at the

maximum speed of 11Mbps by a band of 2.4 GHz (ISM

band) which can freely be used without radio communi-

cation license.

IP address

An address used by computers for communicating in

TCP/IP environment. IP addresses have global and

private addresses. A global address is a unique address in

the world. A private address is a unique address within a

closed network.

LAN (Local Area Network)

An environment connecting computers within a rela-

tively small range, such as the same floor and building.

MAC address (Media Access Control Address)

A physical address inherent to a network card. For

Ethernet, the top three bytes are controlled/assigned as a

vendor code. The remaining three bytes comprise the

code uniquely (to avoid duplication) controlled by each

vendor. As a result, there is no Ethernet card with the

same physical address in the world. In Ethernet, the

frame transmission/reception is performed based on this

address.

MTU (Maximum Transmission Unit)

The maximum size of data which can be transmitted at

one time in networks including the Internet. In an envi-

ronment whose maximum size of data is too large to

correctly receive data, normal communications can be

restored by setting the size of MTU to a smaller value.

Network authentication

The method of authentication performed by wireless

LAN clients to connect with the access point. There are

two types: open system authentication and shared key

authentication. The type of authentication must be set

to each client and also coincide with the setting of access

point with which to communicate. Network authentica-

tion is sometimes called authentication mode.

Network key

Data that is used for encrypting data in data communi-

cation. The personal computer uses the same network

key both for data encryption and decryption, therefore,

it is necessary to set the same network key as the other

side of communication.

Network name (SSID: Service Set Identifier)

The network name is a unique identifier attached to the

WLAN packet header that acts as a password when the

client attempts to connect to a WLAN. The SSID differ-

entiates one WLAN from another so all WLAN devices

attempting to connect to a specific WLAN must use the

same SSID.SSID’s are transmitted in cleartext, thus

supplying no security to the WLAN.

Wireless LAN User’s Guide

Open system authentication

An 802.11 wireless LAN authentication method. Open

System does not exchange any key or other information,

it is a simple request by the mobile station to be authenti-

cated without verifying identity.

PPPoE (Point to Point Protocol over Ethernet)

A method of allowing the authentication protocol

adopted in telephone line connection (PPP) to be used

over an Ethernet.

Protocol

A procedure or rule of delivering data among computers.

Ordered data communication is allowed by making all

conditions required for communication including the

method of data transmission/reception and actions upon

communication errors into procedures.

Shared key authentication

An 802.11 wireless LAN authentication method. When a

client attempts to associate to an access point, the access

point will send a challenge to the client. The client

encrypts the challenge with the network key and sends it

back to the access point. If the access point can decrypt

the challenge, then authentication has succeeded.

SSID (Service Set Identifier)

See “Network name”

Subnet mask

TCP-IP network is controlled by being divided into

multiple smaller networks (subnets). IP address consists

of the subnet address and the address of each computer.

Subnet mask defines how many bits of IP address

comprise the subnet address. The same value shall be set

among computers communicating with each other.

TCP/IP (Transmission Control Protocol/Internet

Protocol)

A standard protocol of the Internet.

Wi-Fi

Short for “Wireless Fidelity”. A term meant to be used

generically when referring to any type of 802.11 network,

whether 802.11b, 802.11a, 802.11g, etc.

IP address information

If IP address is unknown, set IP address as follows:

If you have an access point (DHCP server) on the

network, set the IP address as follows:

[Obtain an IP address automatically]

If the IP address is already assigned to the computer in

the network, ask the network administrator to check the

IP address to be set for the computer.

If no access point is found in the network:

An IP address is expressed with four values in the range

between 1 and 255.

Set the each computer as follows: The value in paren-

theses is a subnet mask.

Computer A: 192.168.100.2 (255.255.255.0)

Computer B: 192.168.100.3 (255.255.255.0)

Computer C: 192.168.100.4 (255.255.255.0)

Computer X: 192.168.100.254 (255.255.255.0)

IP addressing is much more complicated

than can be briefly explained in this

document. You are advised to consult with

your network administrator for additional

information.

A DHCP server is a server that

automatically assigns IP addresses to

computers or other devices in the network.

There is no DHCP server for the AdHoc

network.
