Before Using the W ireless LAN
T he Integrated Wireless LAN is an optional device
available for Fujitsu mobile computers. T his 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. K eep
this manual in a safe place for reference while using the
wireless module.
Types of W ireless LANs Covered by this Document
T his 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 T 3010 model, your wireless module
is the Intel PROSet wireless LAN; if your system is a
T 3010D model, your wireless module is the Atheros
wireless LAN.
Characteristics of the W ireless M odule
T his wireless module is a mini-PCI card attached to a
mini-PCI slot inside the computer.
T he main characteristics are as follows:
It operates in the 2.4 GH z Industrial, Scientific, and
Medical (ISM) RF band; additionally, the Atheros
wireless LAN operates in the 5 GH z 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.
Figure A-1. Ad Hoc M ode Network
52
T his wireless module is Wi-Fi compliant. T he Intel
PROSet module can communicate at a maximum data
rate of 11 Mbps; the Atheros module can communicate at the maximum data rate of 54 Mbps.
T he maximum communication range is approximately 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.
T he wireless modules support a number of industrystandard security mechanisms, including WEP, T K IP,
and 802.1x/EAP (LEAP, T LS, PEAP, MD5).
W ireless LAN M odes Using this W ireless M odule
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 functions, 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.

Access Point*
Wireless LAN
* An optional hub for a wired
LAN may be required depending
upon the type of access point used.
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.
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 recommended 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 location. During the use of a microwave oven or other
equipment generating strong high-frequency energy, in
particular, the personal computer may be highly susceptible to the energy and unable to communicate
properly.
■
Broadcast stations or wireless communication equipment that operate in the 2.4GHz or 5GHz RF Frequency 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.
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.

Troubleshooting
Causes and countermeasures for troubles you may encounter while using your wireless LAN are described in the
following table.
Problem
Unavailable
network
connection
Possible Cause
Incorrect network
name (SSID) or
network key
Possible Solution
Ad hoc connection: verify that the network names (SSID’s) and network
keys (W EP) 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·
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 shortening 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 O N. Also verify “ Disable Radio” is
not checked in “ Network setting” window. Refer to “ Starting Transmission” on page 54.
The computer to be
connected is turned
off
Check if the computer to be connected is turned O N.
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.
Incorrectlyperformed network
setting
Check the protocol, work group name or shared setting.

(continued)
Possible Cause
It takes too long to
retrieve the network
and display the
connected
computers.
Possible Solution
Retrieve computers as follow:
1. Click [Start] button, then click [Search].
2. Click [Computers or people].
3. Click [Computers on the network].
4. Input the name of computer to be connected with in [Computer
name] and click [Search].
5. Double-click the icon of connected computer.·
Incorrect setting of IP
address
Check the network setting.
“Setting the network” on page 57.
In case of using TCP/IP protocol, you can check IP address as follows:
1.
Click [Start] -> [All programs] -> [Accessories] ->
[Command prompt].·
2.
In [Command prompt] or [MS-DOS prompt] window, input
[IPCONFIG] command as follows, then press [Enter] key.
Example: In case of C drive being the hard disk:
C:\ipconfig [Enter]
Check that the IP address is correctly displayed:.
IP Address................: 10.0.1.3
Subnet Mask.............: 255.255.255.0
Default Gateway.........: 10.0.1.1
When IP address is displayed as [169.254.XXX.YYY] or [0.0.0.0],
IP address is not correctly fetched from the access point. In that
case, restart the computer itself. If the display is still unchanged,
check the setting of TCP/IP.
If [Cable Disconnected] or [Media Disconnected] is displayed
without showing IP address, check the setting of network name
(SSID) and network key. Also, set the network authentication
according to the access point.
Communication
is disconnected
soon after
connection to
the access point
Access control may
be disabled
Check the setting of “Enable network access control using IEEE
802.1X”.Refer to “Assigning parameters” on page 55.
When restricting the access of wireless LAN clients using IEEE802.1X
authentication, put a check mark on “Enable network access control
using IEEE 802.1X”.
When using at home, remove a check mark on “Enable network access
control using IEEE802.1X”.
For the method of setting related with IEEE802.1X authentication, refer
to the access point manual.
Authentication

W ireless 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
page 52.
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 page 52.
Channel
T he frequency band of wireless LAN to be used in
communications over wireless LAN or at the access
point.
DH CP (Dynamic Host Configuration Protocol)
A protocol used for automatically fetching communication parameters such as I P addresses. T he side which
assigns IP address is called DH CP server and the side
that is assigned it is called DH CP 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.
I EEE802.11a
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 5GH z band
which can freely be used without radio communication
license.
I EEE802.11b
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 GH z (ISM
band) which can freely be used without radio communication license.
I P address
An address used by computers for communicating in
TCP/I P environment. IP addresses have global and
64
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 relatively 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. T he 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.
MT U (Maximum Transmission Unit)
T he maximum size of data which can be transmitted at
one time in networks including the Internet. In an environment whose maximum size of data is too large to
correctly receive data, normal communications can be
restored by setting the size of MT U to a smaller value.
Network authentication
T he method of authentication performed by wireless
LAN clients to connect with the access point. T here are
two types: open system authentication and shared key
authentication. T he type of authentication must be set
to each client and also coincide with the setting of access
point with which to communicate. Network authentication is sometimes called authentication mode.
Network key
Data that is used for encrypting data in data communication. T he 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 (SSI D: Service Set Identifier)
T he 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. T he SSID differentiates one WLAN from another so all WLAN devices
attempting to connect to a specific WLAN must use the
same SSID.SSI D’s are transmitted in cleartext, thus
supplying no security to the WLAN.
W i r e l e s s L A N U s e r ’s G u i d e
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 authenticated 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
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.
If I P address is unknown, set I P address as follows:
If you have an access point (DH CP server) on the
network, set the IP address as follows:
[Obtain an IP address automatically]
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.
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: T he value in parentheses 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)
