23 24Infrastructure Mode—Networks that function in infrastructure mode consist of devicesthat communicate with each other through an access point.Wireless devices cancommunicate with wired networks or other wireless devices by going through an accesspoint.Infrastructure mode is also called a Basic Service Set (BSS), if it consists of wirelessdevices and a wired network.Networks that function in infrastructure mode are mostuseful when a WLAN requires access to a wired LAN for services such as file sharingand printing.IP Address—An Internet Protocol (IP) address is an identifier for a device or computeron a TCP/IP network.An IP address is a 32-bit numeric address written as four numbersseparated by decimal points.0 to 255 is the available range for each number.1.225.37.123 is an example of a valid IP address.LAN—A local-area network (LAN) is a computer network that spans a relatively smallarea,such as one building or a small group of buildings.Each node in a LAN can accessdata and devices anywhere on the LAN.However, each node must have a separate CPUto execute programs.MAC Address—A Media Access Control (MAC) address is an identifier for each node ofa network.MAC addresses are unique hardware numbers assigned to each computer ordevice.A MAC address consists of twelve numbers written as six pairs separated bycolons or dashes.11:22:33:44:55:66 is an example of a valid MAC address.Node—A node is any device or computer on a network.SSID—A Service Set Identifier (SSID) is an alphanumeric identifier that acts as apassword for devices on a WLAN. SSIDs are case-sensitive and consist of a minimum oftwo characters and a maximum of 32 characters.SSIDs can function as rudimentarysecurity and can also be used for network segmenting.SSIDs differentiate betweenWLANs,so all access points and devices attempting to connect to a specific WLAN mustuse identical SSIDs.myssid is an example of a valid SSID.TCP/IP—Transmission Control Protocol/Internet Protocol (TCP/IP) is a collection ofcommunications protocols for connecting hosts to the Internet.TCP/IP is the industrystandard for transmitting data over networks.WEP—Wired Equivalent Privacy (WEP) is a security measure available for WLANs tohelp them be as secure as wired LANs.WEP provides security by encrypting data so it isprotected as it is transmitted over radio waves.To read encrypted files you must haveaccess to the password,or key, that decrypts the files.WEP key—A WEP key is a decryption key, or password,that is required to access anyWEP-encrypted data.To effectively enable WEP encryption, you must enter your WEPkey.Wi-Fi—Wireless Fidelity (Wi-Fi) refers to any wireless networking equipment thatadheres to 802.11 standards.Wireless Notebook Adapter—A wireless notebook adapter is a 32-bit wirelessconnection device that fits in the PC card slot of a notebook computer.Wireless Zero Configuration Service—Windows XP offers the Wireless ZeroConfiguration Service to support 802.11b and 802.11g wireless networking.This serviceautomatically polls the area for available wireless access points.If an available wirelessaccess point is found,Windows attempts to connect to the access point.If no availablewireless access points are found,you must manually add the access points.WLAN—A wireless local-area network (WLAN) is a local-area network that uses high-frequency radio waves to communicate between nodes.
25 26FCC/CEFederal Communication Commission Interference StatementThis equipment has been tested and found to comply with the limits for a Class B digitaldevice,pursuant to Part 15 of the FCC Rules.These limits are designed to providereasonable protection against harmful interference in a residential installation.Thisequipment generates,uses and can radiate radio frequency energy and,if not installedand used in accordance with the instructions,may cause harmful interference to radiocommunications.However,there is no guarantee that interference will not occur in aparticular installation.If this equipment does cause harmful interference to radio ortelevision reception,which can be determined by turning the equipment off and on,theuser is encouraged to try to correct the interference by one of the following measures:- Reorient or relocate the receiving antenna.- Increase the separation between the equipment and receiver.- Connect the equipment into an outlet on a circuit different from that to which thereceiver is connected.- Consult the dealer or an experienced radio/TV technician for help.FCC Caution:To assure continued compliance,(example - use only shielded interfacecables when connecting to computer or peripheral devices).Any changes ormodifications not expressly approved by the party responsible for compliance could voidthe user's authority to operate this equipment.This device complies with Part 15 of the FCC Rules.Operation is subject to thefollowing two conditions:(1) This device may not cause harmful interference,and (2) thisdevice must accept any interference received,including interference that may causeundesired operation.IMPORTANT NOTE:FCC RF Radiation Exposure Statement:This equipment complies with FCC RF radiation exposure limits set forth for anuncontrolled environment.This equipment should be installed and operated with aminimum distance of 0.5 centimeters (0.2 inch) between the radiator and your body.This transmitter must not be co-located or operating in conjunction with any otherantenna or transmitter.R&TTE Compliance StatementThis equipment complies with all the requirements of the DIRECTIVE 1999/5/EC OFTHE EUROPEAN PARLIAMENT AND THE COUNCIL of 9 March 1999 on radioequipment and telecommunication terminal Equipment and the mutual recognition oftheir conformity (R&TTE).The R&TTE Directive repeals and replaces in the directive98/13/EEC (Telecommunications Terminal Equipment and Satellite Earth StationEquipment) As of April 8, 2000.SafetyThis equipment is designed with the utmost care for the safety of those who install anduse it.However, special attention must be paid to the dangers of electric shock and staticelectricity when working with electrical equipment.All guidelines of this manual and ofthe computer manufacturer must therefore be allowed at all times to ensure the safe useof the equipment.EU Countries intended for useThe ETSI version of this device is intended for home and office use in Austria,Belgium,Denmark,Finland,France (with Frequency channel restrictions),Germany,Greece,Iceland,Ireland,Italy, Luxembourg,Norway,The Netherlands, Portugal, Spain, Sweden,Switzerland and United Kingdom.The ETSI version of this device is also authorized for use in EFTA member states Iceland,Liechtenstein,Norway and Switzerland.EU Countries Not intended for useNone.Potential restrictive useFrance:Only channels 10,11,12,and13Technical SupportBuffalo Technology offers toll-free technical support 24 hours a day, 7 days a week forthis product.Customers in the United States and Canada can obtain technical supportusing the following information:Online Help—Available on the AirNavigator CD enclosed with your purchase.Website—www.buffalotech.com/wireless E-mail—info@buffalotech.comTelephone—866.752.6210The constantly evolving state of wireless products and operating systems requires BuffaloTechnology to occasionally release updated software to take advantage of newtechnologies and to comply with industry standards.For the most recent software,firmware,driver, and technical whitepaper releases available,please visit the BuffaloTechnology website.
