ASUS WLAN Card 33Chapter 3 - ReferenceChapter 3Windows SettingsConfig - Encryption TabLets you configure the ASUS WLAN Card encryption settings. For dataconfidentiality in a wireless environment, IEEE 802.11 specifies a WiredEquivalent Privacy (WEP) algorithm to offer transmission privacy similar towired network. The WEP uses keys to encrypt transmit data packets and decryptreceived data packets. The encryption process can scramble frame bits to avoiddisclosure to others.Pull Down MenusData encryption (WEP enabled)This option allows you to enable or disable the Wired Equivalent Privacy (WEP)function. If this check box is selected, a WEP Key is used to encrypt your databefore it is transmitted over the air.If you enable WEP encryption, you will only be able to communicate withwireless devices that have use the same WEP keys.WEP KeyThis option is enable only if you enable WEP Encryption. The WEP Key is a64 bits (5 byte) or 128 bits (13 byte) Hexadecimal digits that is used to encrypttransmit data packets and decrypt received data packets.Key FormatYou can enter the WEP Key as a Hexadecimal digits (0~9, a~f, and A~F), or asASCII characters, based on the state of the Key Format.
34 ASUS WLAN CardChapter 3 - ReferenceChapter 3Windows SettingsKey LengthFor 64 bits encryption, each Key contains exactly 10 hex digits, or 5 ASCIIcharacters. For 128 bits encryption, each Key contains exactly 26 hex digits, or13 ASCII characters.Two ways to assign WEP keys1. Manual Assignment - When you click this button, the cursor appearsin the field for Key 1. For 64-bit encryption, you are required to enterfour WEP Keys. Each Key contains exactly 10 hex digits (0~9, a~f, andA~F). For 128-bit encryption, you are required to enter four WEP Keys.Each Key contains exactly 26 hex digits (0~9, a~f, and A~F).2. Automatic Generation - Type a combination of up to 64 letters, num-bers, or symbols in the Passphrase column, then the Wireless SettingsUtility uses an algorithm to generate four WEP Keys for encryption.NOTE: This function ease users from having to remember theirpasswords and is compatible to some existing WLAN utilities, butit is not very secure. "Manual Assignment" is more secure.Default KeyThe Default Key field lets you specify which of the four encryption keys youuse to transmit data on your wireless LAN. You can change the default key byclicking on the down arrow at the right of this field, selecting the number of thekey you want to use and then clicking the Apply button. As long as the AccessPoint or station with which you are communicating has the same key in thesame position, you can use any of the keys as the default.You then click the Apply button to create your encryption keys. After you clickthe Apply button, the Wireless Settings Utility uses asterisks to mask yourkeys.NOTE: Click the Apply or OK button to save the encryption set-tings. The keys you entered will be masked by asterisks.
ASUS WLAN Card 35Chapter 3 - ReferenceChapter 3Windows Settings64/128bits versus 40/104bitsYou may be confused about configuring WEP encryption, especially whenusing multiple wireless LAN products from different vendors. There aretwo levels of WEP Encryption: 64 bits and 128 bits.First, 64 bit WEP and 40 bit WEP are the same encryption method and caninteroperate in the wireless network. This lower level of WEP encryptionuses a 40 bit (10 Hex character) as a “secret key” (set by user), and a 24 bit“Initialization Vector” (not under user control). This together makes 64bits (40 + 24). Some vendors refer to this level of WEP as 40 bits andothers refer to this as 64 bits. ASUS WLAN products use the term 64 bitswhen referring to this lower level of encryption.Second, 104 bit WEP and 128 bit WEP are the same encryption methodand can interoperate in the wireless network. This higher level of WEPencryption uses a 104 bit (26 Hex character) as a “secret key” (set by user),and a 24 bit “Initialization Vector” (not under user control). This togethermakes 128 bits (104 + 24). Some vendors refer to this level of WEP as 104bits and others refer to this as 128 bits. ASUS WLAN products use theterm 128 bits when referring to this higher level of encryption.Click Apply to save and activate the new configurations.

ASUS WLAN CardChapter 4 - TroubleshootingChapter 4Troubleshooting60Cannot connect to a Station (ASUS WLAN Card)Follow the procedure below to configure your ASUS WLAN Card.a. Verify that the “Network Type” is in “Ad Hoc” mode.b. Verify that the “SSID” of your ASUS WLAN Card is set to the same“SSID” of the other station (or another ASUS WLAN Card).c. Verify that the “channel” of the ASUS WLAN Card is “Auto” or set tothe same “channel” of the other station (or another ASUS WLAN Card).d. Verify that the “Encryption” type is the same as the other station (oranother ASUS WLAN Card). If “WEP” encryption is enabled, youmust set the same “WEP” Keys on both stations.Bad link quality or bad signal strengthThere are two possible reasons. First is radio interference, keep the environmentaround the ASUS WLAN Card away from microwave ovens and large metalobjects. Then try to reorient the ASUS WLAN Card antenna. Second is thedistance, decrease the distance between your ASUS WLAN Card and the AccessPoint or station (or another ASUS WLAN Card).The TCP/IP protocol did not bind to the ASUS WLAN PC Card.This will occur when the computer already has six TCP/IP bindings in Windows98 or ten bindings in Windows Me. These limits are imposed by the Microsoftoperating system.Solution: If your computer already has the maximum number of TCP/IPbindings, remove one of the network adapters from the Network configurationbefore installing the ASUS WLAN Card driver.
ASUS WLAN Card 61Chapter 5Chapter 5 - GlossaryGlossary5. GlossaryAccess Point (AP)An networking device that seamlessly connects wired and wireless networks. AccessPoints combined with a distributed system support the creation of multiple radio cellsthat enable roaming throughout a facility.Ad HocA wireless network composed solely of stations within mutual communication rangeof each other (no Access Point).Basic Rate SetThis option allows you to specify the data transmission rate.Basic Service Area (BSS)A set of stations controlled by a single coordination function.BroadbandA type of data transmission in which a single medium (such as cable) carriesseveral channels of data at once.ChannelAn instance of medium use for the purpose of passing protocol data units that may beused simultaneously, in the same volume of space, with other instances of medium use(on other channels) by other instances of the same physical layer, with an acceptablylow frame error ratio due to mutual interference.ClientA client is the desktop or mobile PC that is connected to your network.COFDM (for 802.11a or 802.11g)Signal power alone is not enough to maintain 802.11b-like distances in an 802.11a/genvironment. To compensate, a new physical-layer encoding technology was designedthat departs from the traditional direct-sequence technology being deployed today. Thistechnology is called COFDM (coded OFDM). COFDM was developed specificallyfor indoor wireless use and offers performance much superior to that of spread-spectrumsolutions. COFDM works by breaking one high-speed data carrier into several lower-speed subcarriers, which are then transmitted in parallel. Each high-speed carrier is 20MHz wide and is broken up into 52 subchannels, each approximately 300 KHz wide.COFDM uses 48 of these subchannels for data, while the remaining four are used forerror correction. COFDM delivers higher data rates and a high degree of multipathreflection recovery, thanks to its encoding scheme and error correction.
62 ASUS WLAN CardChapter 5Chapter 5 - GlossaryGlossaryEach subchannel in the COFDM implementation is about 300 KHz wide. At the lowend of the speed gradient, BPSK (binary phase shift keying) is used to encode 125Kbps of data per channel, resulting in a 6,000-Kbps, or 6 Mbps, data rate. Usingquadrature phase shift keying, you can double the amount of data encoded to 250 Kbpsper channel, yielding a 12-Mbps data rate. And by using 16-level quadrature amplitudemodulation encoding 4 bits per hertz, you can achieve a data rate of 24 Mbps. The802.11a/g standard specifies that all 802.11a/g-compliant products must support thesebasic data rates. The standard also lets the vendor extend the modulation scheme beyond24 Mbps. Remember, the more bits per cycle (hertz) that are encoded, the moresusceptible the signal will be to interference and fading, and ultimately, the shorter therange, unless power output is increased.Default KeyThis option allows you to select the default WEP key. This option allows youto use WEP keys without having to remember or write them down. The WEPkeys generated using the Pass Phrase is compatible with other ASUS WLANproducts. The Pass Phrase option is not as secure as manual assignment.Device NameAlso known as DHCP client ID or network name. Sometimes provided by anISP when using DHCP to assign addresses.DHCP (Dynamic Host Configuration Protocol)This protocol allows a computer (or many computers on your network) to beautomatically assigned a single IP address from a DHCP server.DNS Server Address (Domain Name System)DNS allows Internet host computers to have a domain name and one or more IPaddresses. A DNS server keeps a database of host computers and their respective domainnames and IP addresses, so that when a user enters a domain name into the Internetbrowser, the user is sent to the proper IP address. The DNS server address used by thecomputers on your home network is the location of the DNS server your ISP has assigned.DSL Modem (Digital Subscriber Line)A DSL modem uses your existing phone lines to transmit data at high speeds.Direct-Sequence Spread Spectrum (for 802.11b)Spread spectrum (broadband) uses a narrowband signal to spread the transmission overa segment of the radio frequency band or spectrum. Direct-sequence is a spread spectrumtechnique where the transmitted signal is spread over a particular frequency range.Direct-sequence systems communicate by continuously transmitting a redundant patternof bits called a chipping sequence. Each bit of transmitted data is mapped into chipsand rearranged into a pseudorandom spreading code to form the chipping sequence.The chipping sequence is combined with a transmitted data stream to produce theoutput signal.
ASUS WLAN Card 63Chapter 5Chapter 5 - GlossaryGlossaryWireless mobile clients receiving a direct-sequence transmission use the spreadingcode to map the chips within the chipping sequence back into bits to recreate the originaldata transmitted by the wireless device. Intercepting and decoding a direct-sequencetransmission requires a predefined algorithm to associate the spreading code used bythe transmitting wireless device to the receiving wireless mobile client.This algorithm is established by IEEE 802.11b specifications. The bit redundancy withinthe chipping sequence enables the receiving wireless mobile client to recreate the originaldata pattern, even if bits in the chipping sequence are corrupted by interference. Theratio of chips per bit is called the spreading ratio. A high spreading ratio increases theresistance of the signal to interference. A low spreading ratio increases the bandwidthavailable to the user. The wireless device uses a constant chip rate of 11Mchips/s for alldata rates, but uses different modulation schemes to encode more bits per chip at thehigher data rates. The wireless device is capable of an 11 Mbps data transmission rate,but the coverage area is less than a 1 or 2 Mbps wireless device since coverage areadecreases as bandwidth increases.EncryptionThis provides wireless data transmissions with a level of security. This option allowsyou to specify a 64-bit or a 128-bit WEP key. A 64-bit encryption contains 10 hexadecimaldigits or 5 ASCII characters. A 128-bit encryption contains 26 hexadecimal digits or 13ASCII characters.64-bit and 40-bit WEP keys use the same encryption method and can interoperate onwireless networks. This lower level of WEP encryption uses a 40-bit (10 hexadecimaldigits assigned by the user) secret key and a 24-bit Initialization Vector assigned by thedevice. 104-bit and 128-bit WEP keys use the same encryption method.All wireless clients in a network must have identical WEP keys with the access point toestablish connection. Keep a record of the WEP encryption keys.Extended Service Set (ESS)A set of one or more interconnected basic service set (BSSs) and integratedlocal area networks (LANs) can be configured as an Extended Service Set.ESSID (Extended Service Set Identifier)You must have the same ESSID entered into the gateway and each of its wirelessclients. The ESSID is a unique identifier for your wireless network.EthernetThe most widely used LAN access method, which is defined by the IEEE 802.3 standard.Ethernet is normally a shared media LAN meaning all devices on the network segmentshare total bandwidth. Ethernet networks operate at 10Mbps using CSMA/CD to runover 10-BaseT cables.

The IEEE sets standards fornetworking, including Ethernet LANs. IEEE standards ensure interoperability betweensystems of the same type.IEEE 802.11IEEE 802.xx is a set of specifications for LANs from the Institute of Electrical andElectronic Engineers (IEEE). Most wired networks conform to 802.3, the specificationfor CSMA/CD based Ethernet networks or 802.5, the specification for token ringnetworks. 802.11 defines the standard for wireless LANs encompassing threeincompatible (non-interoperable) technologies: Frequency Hopping Spread Spectrum(FHSS), Direct Sequence Spread Spectrum (DSSS), and Infrared. 802.11 specifies acarrier sense media access control and physical layer specifications for 1 and 2 Mbpswireless LANs.IEEE 802.11a (54Mbits/sec)Compared with 802.11b: The 802.11b standard was designed to operate in the 2.4-GHz ISM (Industrial, Scientific and Medical) band using direct-sequence spread-spectrum technology. The 802.11a standard, on the other hand, was designed to operatein the more recently allocated 5-GHz UNII (Unlicensed National InformationInfrastructure) band. And unlike 802.11b, the 802.11a standard departs from thetraditional spread-spectrum technology, instead using a frequency division multiplexingscheme that's intended to be friendlier to office environments.The 802.11a standard, which supports data rates of up to 54 Mbps, is the Fast Ethernetanalog to 802.11b, which supports data rates of up to 11 Mbps. Like Ethernet and FastEthernet, 802.11b and 802.11a use an identical MAC (Media Access Control). However,while Fast Ethernet uses the same physical-layer encoding scheme as Ethernet (onlyfaster), 802.11a uses an entirely different encoding scheme, called OFDM (orthogonalfrequency division multiplexing).The 802.11b spectrum is plagued by saturation from wireless phones, microwave ovensand other emerging wireless technologies, such as Bluetooth. In contrast, 802.11aspectrum is relatively free of interference.
ASUS WLAN Card 65Chapter 5Chapter 5 - GlossaryGlossaryThe 802.11a standard gains some of its performance from the higher frequencies atwhich it operates. The laws of information theory tie frequency, radiated power anddistance together in an inverse relationship. Thus, moving up to the 5-GHz spectrumfrom 2.4 GHz will lead to shorter distances, given the same radiated power and encodingscheme.Compared with 802.11g: 802.11a is a standard for access points and radio NICs thatis ahead of 802.11g in the market by about six months. 802.11a operates in the 5GHzfrequency band with twelve separate non-overlapping channels. As a result, you canhave up to twelve access points set to different channels in the same area without theminterfering with each other. This makes access point channel assignment much easierand significantly increases the throughput the wireless LAN can deliver within a givenarea. In addition, RF interference is much less likely because of the less-crowded 5GHz band.IEEE 802.11b (11Mbits/sec)In 1997, the Institute of Electrical and Electronics Engineers (IEEE) adopted the 802.11standard for wireless devices operating in the 2.4 GHz frequency band. This standardincludes provisions for three radio technologies: direct sequence spread spectrum,frequency hopping spread spectrum, and infrared. Devices that comply with the 802.11standard operate at a data rate of either 1 or 2 Mbps.In 1999, the IEEE created the 802.11b standard. 802.11b is essentially identical to the802.11 standard except 802.11b provides for data rates of up to 11 Mbps for directsequence spread spectrum devices. Under 802.11b, direct sequence devices can operateat 11 Mbps, 5.5 Mbps, 2 Mbps, or 1 Mbps. This provides interoperability with existing802.11 direct sequence devices that operate only at 2 Mbps.Direct sequence spread spectrum devices spread a radio signal over a range offrequencies. The IEEE 802.11b specification allocates the 2.4 GHz frequency bandinto 14 overlapping operating Channels. Each Channel corresponds to a different set offrequencies.IEEE 802.11g802.11g is a new extension to 802.11b (used in majority of wireless LANs today) thatbroadens 802.11b's data rates to 54 Mbps within the 2.4 GHz band using OFDM(orthogonal frequency division multiplexing) technology. 802.11g allows backwardcompatibility with 802.11b devices but only at 11 Mbps or lower, depending on therange and presence of obstructions.InfrastructureA wireless network centered about an access point. In this environment, the accesspoint not only provides communication with the wired network but also mediateswireless network traffic in the immediate neighborhood.IP (Internet Protocol)The TCP/IP standard protocol that defines the IP datagram as the unit of informationpassed across an Internet and provides the basis for connectionless packet deliveryservice.

These cards can be used for various functions, includingmemory storage, land line modems and wireless modems.PPP (Point-to-Point Protocol)PPP is a protocol for communication between computers using a serial interface, typicallya personal computer connected by phone line to a server.PPPoE (Point-to-Point Protocol over Ethernet)Point-to-Point Protocol is a method of secure data transmission. PPP using Ethernet toconnect to an ISP.PreambleAllows you to set the preamble mode for a network to Long, Short, or Auto.The default preamble mode is Long.Radio Frequency (RF) Terms: GHz, MHz, HzThe international unit for measuring frequency is Hertz (Hz), equivalent to the olderunit of cycles per second. One megahertz (MHz) is one million Hertz. One gigahertz(GHz) is one billion Hertz. The standard US electrical power frequency is 60 Hz, theAM broadcast radio frequency band is 0.55-1.6 MHz, the FM broadcast radio frequencyband is 88-108 MHz, and wireless 802.11 LANs operate at 2.4 GHz.SSID (Service Set Identifier)SSID is a group name shared by every member of a wireless network. Only client PCswith the same SSID are allowed to establish a connection. Enabling the Response toBroadcast SSID requests option allows the device to broadcast its SSID in a wirelessnetwork. This allows other wireless devices to scan and establish communication withthe device. Unchecking this option hides the SSID to prevent other wireless devicesfrom recognizing and connecting to the device.StationAny device containing IEEE 802.11 wireless medium access conformity.Subnet MaskA subnet mask is a set of four numbers configured like an IP address. It is used to createIP address numbers used only within a particular network.
