52Before Using the Wireless LAN The Integrated Wireless LAN is an optional device Types of Wireless LANs Covered by this DocumentThis 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 LANIf your system is a T3010 model, your wireless moduleCharacteristics of the Wireless ModuleThis 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 ModuleAd 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 Networkavailable for Fujitsu mobile computers. This manualdescribes the basic operating prodecures for the Wireless LAN (referred to as the "wireless module" inthis manual) and how to set up a wireless LAN network.Before using this wireless module, read this manualcarefully to ensure correct operation of the device. Keepthis manual in a safe place for reference while using thewireless module.is the Intel PROSet wireless LAN; if your system is a T3010D model, your wireless module is the Atheroswireless LAN.
53Wireless LAN User’s GuideAccess 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 ModuleThe 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 COMMUNICATIONSThis 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.Figure A-2.

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 disabledCheck 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 method may have been entered incorrectlyRe-enter your WEP key and verify that your authentication method (Open or Shared) is correct.Problem Possible Cause Possible Solution
64Wireless LAN GlossaryAccess pointA 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 hocA 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.ChannelThe 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.IEEE802.11aOne 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. IEEE802.11bOne 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 addressAn 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 authenticationThe 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 keyData 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.
65Wireless LAN User’s GuideOpen system authenticationAn 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.ProtocolA 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 authenticationAn 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 maskTCP-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.
66IP address informationIf 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.
