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.
53
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.

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 W EP 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·

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.
66
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.
<Example>
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.
