ASUS WLAN AdapterChapter 5 - TroubleshootingChapter 4Troubleshooting445. TroubleshootingThe following troubleshooting guides provide answers to some of the more common problems, which you may encounter while installing or using WLAN Adapter products. If you encounter difculties that are not mentioned in this section, please contact the Wireless LAN Technical Support.Verify if the WLAN Adapter is installed correctly.When the WLAN Adapter setup is complete, you can verify if the driver has been setup properly. Right click My Computer, select Properties, and click the Device Manager tab. Then double-click the Network adapters icon; you should see “802.11g Network Adapter” with an icon of an expansion adapter. There should not be a “!” or “?” (problem) or “x” (disabled) symbol over this icon. There is a yellow exclamation mark or a yellow question mark in Device Manager in front of my WLAN Adapter.To resolve the problem, you should update/reinstall the WLAN Adapter driver. In “Device Manager”, right click 802.11g Network Adapter, select Properties, and select Driver tab. Click on Update Driver button, then follow the “Update Device Driver Wizard” to complete the driver installation. Cannot connect to any access pointsFollow the procedure below to congure your WLAN Adapter.a. Verify that the “Network Type” is in “Infrastructure” mode.b. Verify that the “SSID” of your WLAN Adapter is set to the same “SSID” of an access point.c. Verify that the “Encryption” type is the same as that of an access point. If you enabled “WEP” encryption, you must also set the same WEP Keys on both sides.
ASUS WLAN Adapter 45Chapter 5 - TroubleshootingChapter 4TroubleshootingCannot connect to a Station (WLAN Adapter)Follow the procedure below to congure your WLAN Adapter.a. Verify that the “Network Type” is in “Ad Hoc” mode.b. Verify that the “SSID” of your WLAN Adapter is set to the same “SSID” of the other station (or another WLAN Adapter).c. Verify that the “channel” of the WLAN Adapter is “Auto” or set to the same “channel” of the other station (or another WLAN Adapter).d. Verify that the “Encryption” type is the same as the other station (or another WLAN Adapter). If “WEP” encryption is enabled, you must 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 environment around the WLAN Adapter away from microwave ovens and large metal objects. Then try to reorient the WLAN Adapter antenna. Second is the distance, decrease the distance between your WLAN Adapter and the access point or station (or another WLAN Adapter).The TCP/IP protocol did not bind to the WLAN PC Adapter.This will occur when the computer already has six TCP/IP bindings in Windows 98 or ten bindings in Windows Me. These limits are imposed by the Microsoft operating system.Solution: If your computer already has the maximum number of TCP/IP bindings, remove one of the network adapters from the Network conguration before installing the WLAN Adapter driver.
46 ASUS WLAN AdapterChapter 5Chapter 6 - GlossaryGlossary6. GlossaryAccess Point (AP)A networking device that seamlessly connects wired and wireless networks. Access points combined with a distributed system support the creation of multiple radio cells that enable roaming throughout a facility.Ad HocA wireless network composed solely of stations within mutual communication range of 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) carries several channels of data at once.ChannelAn instance of medium use for the purpose of passing protocol data units that may be used 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 acceptably low 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/g environment. To compensate, a new physical-layer encoding technology was designed that departs from the traditional direct-sequence technology being deployed today. This technology is called COFDM (coded OFDM). COFDM was developed specically for indoor wireless use and offers performance much superior to that of spread-spectrum solutions. 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 20 MHz 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 for error correction. COFDM delivers higher data rates and a high degree of multipath reection recovery, thanks to its encoding scheme and error correction.
ASUS WLAN Adapter 47Chapter 5Chapter 6 - GlossaryGlossaryEach subchannel in the COFDM implementation is about 300 KHz wide. At the low end of the speed gradient, BPSK (binary phase shift keying) is used to encode 125 Kbps of data per channel, resulting in a 6,000-Kbps, or 6 Mbps, data rate. Using quadrature phase shift keying, you can double the amount of data encoded to 250 Kbps per channel, yielding a 12-Mbps data rate. And by using 16-level quadrature amplitude modulation encoding 4 bits per hertz, you can achieve a data rate of 24 Mbps. The 802.11a/g standard species that all 802.11a/g-compliant products must support these basic data rates. The standard also lets the vendor extend the modulation scheme beyond 24 Mbps. Remember, the more bits per cycle (hertz) that are encoded, the more susceptible the signal will be to interference and fading, and ultimately, the shorter the range, unless power output is increased.Default KeyThis option allows you to select the default WEP key. This option allows you to use WEP keys without having to remember or write them down. The WEP keys generated using the Passphrase is compatible with other WLAN products. The Passphrase option is not as secure as manual assignment.Device NameAlso known as DHCP client ID or network name. Sometimes provided by an ISP when using DHCP to assign addresses.DHCP (Dynamic Host Conguration Protocol)This protocol allows a computer (or many computers on your network) to be automatically 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 IP addresses. A DNS server keeps a database of host computers and their respective domain names and IP addresses, so that when a user enters a domain name into the Internet browser, the user is sent to the proper IP address. The DNS server address used by the computers 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 over a segment of the radio frequency band or spectrum. Direct-sequence is a spread spectrum technique where the transmitted signal is spread over a particular frequency range.
48 ASUS WLAN AdapterChapter 5Chapter 6 - GlossaryGlossaryDirect-sequence systems communicate by continuously transmitting a redundant pattern of bits called a chipping sequence. Each bit of transmitted data is mapped into chips and rearranged into a pseudorandom spreading code to form the chipping sequence. The chipping sequence is combined with a transmitted data stream to produce the output signal.Wireless mobile clients receiving a direct-sequence transmission use the spreading code to map the chips within the chipping sequence back into bits to recreate the original data transmitted by the wireless device. Intercepting and decoding a direct-sequence transmission requires a predened algorithm to associate the spreading code used by the transmitting wireless device to the receiving wireless mobile client.This algorithm is established by IEEE 802.11b specications. The bit redundancy within the chipping sequence enables the receiving wireless mobile client to recreate the original data pattern, even if bits in the chipping sequence are corrupted by interference. The ratio of chips per bit is called the spreading ratio. A high spreading ratio increases the resistance of the signal to interference. A low spreading ratio increases the bandwidth available to the user. The wireless device uses a constant chip rate of 11Mchips/s for all data rates, but uses different modulation schemes to encode more bits per chip at the higher 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 area decreases as bandwidth increases.EncryptionThis provides wireless data transmissions with a level of security. This option allows you to specify a 64-bit or a 128-bit WEP key. A 64-bit encryption contains 10 hexadecimal digits or 5 ASCII characters. A 128-bit encryption contains 26 hexadecimal digits or 13 ASCII characters.64-bit and 40-bit WEP keys use the same encryption method and can interoperate on wireless networks. This lower level of WEP encryption uses a 40-bit (10 hexadecimal digits assigned by the user) secret key and a 24-bit Initialization Vector assigned by the device. 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 to establish connection. Keep a record of the WEP encryption keys.Extended Service Set (ESS)A set of one or more interconnected basic service set (BSS) and integrated local area networks (LANs) can be congured as an Extended Service Set.ESSID (Extended Service Set Identier)You must have the same ESSID entered into the gateway and each of its wireless clients. The ESSID is a unique identier for your wireless network.
ASUS WLAN Adapter 49Chapter 5Chapter 6 - GlossaryGlossaryEthernetThe most widely used LAN access method, which is dened by the IEEE 802.3 standard. Ethernet is normally a shared media LAN meaning all devices on the network segment share total bandwidth. Ethernet networks operate at 10Mbps using CSMA/CD to run over 10-BaseT cables. FirewallA rewall determines which information passes in and out of a network. NAT can create a natural rewall by hiding a local network’s IP addresses from the Internet. A Firewall prevents anyone outside of your network from accessing your computer and possibly damaging or viewing your les.GatewayA network point that manages all the data trafc of your network, as well as to the Internet and connects one network to another.IEEEThe Institute of Electrical and Electronics Engineers. The IEEE sets standards for networking, including Ethernet LANs. IEEE standards ensure interoperability between systems of the same type.IEEE 802.11IEEE 802.xx is a set of specications for LANs from the Institute of Electrical and Electronic Engineers (IEEE). Most wired networks conform to 802.3, the specication for CSMA/CD based Ethernet networks or 802.5, the specication for token ring networks. 802.11 denes the standard for wireless LANs encompassing three incompatible (non-interoperable) technologies: Frequency Hopping Spread Spectrum (FHSS), Direct Sequence Spread Spectrum (DSSS), and Infrared. 802.11 species a carrier sense media access control and physical layer specications for 1 and 2 Mbps wireless 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, Scientic and Medical) band using direct-sequence spread-spectrum technology. The 802.11a standard, on the other hand, was designed to operate in the more recently allocated 5-GHz UNII (Unlicensed National Information Infrastructure) band. And unlike 802.11b, the 802.11a standard departs from the traditional spread-spectrum technology, instead using a frequency division multiplexing scheme that's intended to be friendlier to ofce environments. The 802.11a standard, which supports data rates of up to 54 Mbps, is the Fast Ethernet analog to 802.11b, which supports data rates of up to 11 Mbps. Like Ethernet and Fast Ethernet, 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 (only faster), 802.11a uses an entirely different encoding scheme, called OFDM (orthogonal frequency division multiplexing).
50 ASUS WLAN AdapterChapter 5Chapter 6 - GlossaryGlossaryThe 802.11b spectrum is plagued by saturation from wireless phones, microwave ovens and other emerging wireless technologies, such as Bluetooth. In contrast, 802.11a spectrum is relatively free of interference.The 802.11a standard gains some of its performance from the higher frequencies at which it operates. The laws of information theory tie frequency, radiated power and distance together in an inverse relationship. Thus, moving up to the 5-GHz spectrum from 2.4 GHz will lead to shorter distances, given the same radiated power and encoding scheme.Compared with 802.11g: 802.11a is a standard for access points and radio NICs that is ahead of 802.11g in the market by about six months. 802.11a operates in the 5GHz frequency band with twelve separate non-overlapping channels. As a result, you can have up to twelve access points set to different channels in the same area without them interfering with each other. This makes access point channel assignment much easier and signicantly increases the throughput the wireless LAN can deliver within a given area. In addition, RF interference is much less likely because of the less-crowded 5 GHz band.IEEE 802.11b (11Mbits/sec)In 1997, the Institute of Electrical and Electronics Engineers (IEEE) adopted the 802.11 standard for wireless devices operating in the 2.4 GHz frequency band. This standard includes provisions for three radio technologies: direct sequence spread spectrum, frequency hopping spread spectrum, and infrared. Devices that comply with the 802.11 standard 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 the 802.11 standard except 802.11b provides for data rates of up to 11 Mbps for direct sequence spread spectrum devices. Under 802.11b, direct sequence devices can operate at 11 Mbps, 5.5 Mbps, 2 Mbps, or 1 Mbps. This provides interoperability with existing 802.11 direct sequence devices that operate only at 2 Mbps.Direct sequence spread spectrum devices spread a radio signal over a range of frequencies. The IEEE 802.11b specication allocates the 2.4 GHz frequency band into 14 overlapping operating Channels. Each Channel corresponds to a different set of frequencies.IEEE 802.11g802.11g is a new extension to 802.11b (used in majority of wireless LANs today) that broadens 802.11b's data rates to 54 Mbps within the 2.4 GHz band using OFDM (orthogonal frequency division multiplexing) technology. 802.11g allows backward compatibility with 802.11b devices but only at 11 Mbps or lower, depending on the range and presence of obstructions.InfrastructureA wireless network centered about an access point. In this environment, the access point not only provides communication with the wired network but also mediates wireless network trafc in the immediate neighborhood.
ASUS WLAN Adapter 51Chapter 5Chapter 6 - GlossaryGlossaryIP (Internet Protocol)The TCP/IP standard protocol that denes the IP datagram as the unit of information passed across an Internet and provides the basis for connectionless packet delivery service. IP includes the ICMP control and error message protocol as an integral part. It provides the functional equivalent of ISO OSI Network Services.IP AddressAn IP address is a 32-bit number that identies each sender or receiver of information that is sent across the Internet. An IP address has two parts: the identier of a particular network on the Internet and an identier of the particular device (which can be a server or a workstation) within that network. ISM Bands (Industrial, Scientic, and Medicine Bands)Radio frequency bands that the Federal Communications Commission (FCC) authorized for wireless LANs. The ISM bands are located at 902 MHz, 2.400 GHz, and 5.7 GHz.ISP (Internet Service Provider)An organization that provides access to the Internet. Small ISPs provide service via modem and ISDN while the larger ones also offer private line hookups (T1, fractional T1, etc.).LAN (Local Area Network)A communications network that serves users within a dened geographical area. The benets include the sharing of Internet access, les and equipment like printers and storage devices. Special network cabling (10 Base-T) is often used to connect the PCs together. MAC Address (Media Access Control)A MAC address is the hardware address of a device connected to a network.NAT (Network Address Translation)NAT masks a local network’s group of IP addresses from the external network, allowing a local network of computers to share a single ISP account. This process allows all of the computers on your home network to use one IP address. This will enable access to the Internet from any computer on your home network without having to purchase more IP addresses from your ISP.NIC (Network Interface Card)A network adapter inserted into a computer so that the computer can be connected to a network. It is responsible for converting data from stored in the computer to the form transmitted or received.
52 ASUS WLAN AdapterChapter 5Chapter 6 - GlossaryGlossaryPacketA basic message unit for communication across a network. A packet usually includes routing information, data, and sometimes error detection information. PassphraseThe Wireless Settings utility uses an algorithm to generate four WEP keys based on the typed combination.PPP (Point-to-Point Protocol)PPP is a protocol for communication between computers using a serial interface, typically a 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 to connect 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, Hz The international unit for measuring frequency is Hertz (Hz), equivalent to the older unit 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, the AM broadcast radio frequency band is 0.55-1.6 MHz, the FM broadcast radio frequency band is 88-108 MHz, and wireless 802.11 LANs operate at 2.4 GHz. SSID (Service Set Identier)SSID is a group name shared by every member of a wireless network. Only client PCs with the same SSID are allowed to establish a connection. Enabling the Response to Broadcast SSID requests option allows the device to broadcast its SSID in a wireless network. This allows other wireless devices to scan and establish communication with the device. Unchecking this option hides the SSID to prevent other wireless devices from 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 congured like an IP address. It is used to create IP address numbers used only within a particular network.
ASUS WLAN Adapter 53Chapter 5Chapter 6 - GlossaryGlossaryTCP (Transmission Control Protocol)The standard transport level protocol that provides the full duplex, stream service on which many application protocols depend. TCP allows a process or one machine to send a stream of data to a process on another. Software implementing TCP usually resides in the operating system and uses the IP to transmit information across the network.WAN (Wide Area Network)A system of LANs, connected together. A network that connects computers located in separate areas, (i.e., different buildings, cities, countries). The Internet is a wide area network.WECA (Wireless Ethernet Compatibility Alliance)An industry group that certies cross-vender interoperability and compatibility of IEEE 802.11b wireless networking products and to promote that standard for enterprise, small business, and home environments.WPA (Wi-Fi Protected Access)Wi-Fi Protected Access (WPA) is an improved security system for 802.11. It is part of the 802.11i draft security standard. WPA encompasses TKIP (Temporal Key Integrity Protocol) along with MIC (Message Integrity Check) and other xes to WEP such as Weak IV (Initialization Vector) ltering and Random IV generation. TKIP uses 802.1x to deploy and change temporary keys as opposed to static WEP keys once used in the past. It is a signicant improvement over WEP. WPA is part of a complete security solution. WPA also requires authentication servers in enterprise security solutions.Requirements(1) A WPA compatible access point or Wireless router, (2) Operating system updates that support WPA. In XP, an updated Windows Zero Cong service is needed.
