Other computers can send and receive email and access the Web as if it were connected directly to the Internet. ASUS WLAN Card 15 Chapter 2 - Installation Soft AP Access Control and WDS Soft AP mode allows for Access Control and WDS configuration. Chapter 2 Quick Start Access Control The AP provides facilities to limit the wireless clients that associate with it and the data packets that can forward through it. Filters provide network security or improve performance by eliminating broadcast/multicast packets from the radio network. The Access Control List (ACL) contains MAC addresses for wireless clients allowed to associate with the AP. This provides security by preventing unauthorized access. The AP also uses a disallowed address list of destinations. This feature prevents the AP from communicating with specified destinations. This can include network devices that do not require communication with the AP or its wireless clients. Network Range Extension For multiple WLAN connections, the AP incorporates the powerful WDS (Wireless Distribution System). WDS allows direct connection, repeating, or bridging between multiple WLANs through wireless communications instead of wired connectivity. This way you can extend the coverage of your network without having to use cables to link the Access Points. With this advanced technology, MIS professionals can establish multiple WLANs for optimal signal reception without wasting cost and time in laying down long winding cables. Access Control and WDS Settings Clicking Apply after configuring Soft AP will give two extra tabs - Access Control and WDS. 16 Here is a view of the extra Soft AP tabs from the Basic page. ASUS WLAN Card Chapter 2 - Installation Chapter 2 Quick Start IMPORTANT: Before setting up a WDS network, make sure all APs have the same Channel and WEP encryption settings. Enter a MAC Address on the Access Control page and select "Accept" or "Reject" or "Disable". Enter a MAC Address on the WDS page and select "WDS enabled" or uncheck to disable this function. Note: Both the Access Control and WDS functions require MAC address using 12 hexidecimal numbers. Soft AP Mode will also provide two extra tabs on the Status pages - Association Table and Event Log. The Association Table shows clients that are currently connected to the Soft AP. The Event Log tracks messages associated with the Soft AP. IMPORTANT: If the end points of a chain are connected to each other a loop is created. Normally it is advised to avoid loops involving bridges as it can lead to performance breakdowns, and broadcast and multi-cast storms.

For data confidentiality in a wireless environment, IEEE 802.11 specifies a Wired Equivalent Privacy (WEP) algorithm to offer transmission privacy similar to wired network. The WEP uses keys to encrypt transmit data packets and decrypt received data packets. The encryption process can scramble frame bits to avoid disclosure to others. Pull Down Menus Data 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 data before it is transmitted over the air. If you enable WEP encryption, you will only be able to communicate with wireless devices that have use the same WEP keys. WEP Key This option is enable only if you enable WEP Encryption. The WEP Key is a 64 bits (5 byte) or 128 bits (13 byte) Hexadecimal digits that is used to encrypt transmit data packets and decrypt received data packets. Key Format You can enter the WEP Key as a Hexadecimal digits (0~9, a~f, and A~F), or as ASCII characters, based on the state of the Key Format. ASUS WLAN Card 35 Chapter 3 - Reference Key Length For 64 bits encryption, each Key contains exactly 10 hex digits, or 5 ASCII characters. For 128 bits encryption, each Key contains exactly 26 hex digits, or 13 ASCII characters. Two ways to assign WEP keys Chapter 3 Windows Settings 1. Manual Assignment - When you click this button, the cursor appears in the field for Key 1. For 64-bit encryption, you are required to enter four WEP Keys. Each Key contains exactly 10 hex digits (0~9, a~f, and A~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, numbers, or symbols in the Passphrase column, then the Wireless Settings Utility uses an algorithm to generate four WEP Keys for encryption. NOTE: This function ease users from having to remember their passwords and is compatible to some existing WLAN utilities, but it is not very secure. "Manual Assignment" is more secure. Default Key The Default Key field lets you specify which of the four encryption keys you use to transmit data on your wireless LAN. You can change the default key by clicking on the down arrow at the right of this field, selecting the number of the key you want to use and then clicking the Apply button. As long as the Access Point or station with which you are communicating has the same key in the same position, you can use any of the keys as the default. You then click the Apply button to create your encryption keys. After you click the Apply button, the Wireless Settings Utility uses asterisks to mask your keys. NOTE: Click the Apply or OK button to save the encryption settings. The keys you entered will be masked by asterisks. 36 ASUS WLAN Card Chapter 3 - Reference 64/128bits versus 40/104bits You may be confused about configuring WEP encryption, especially when using multiple wireless LAN products from different vendors. There are two levels of WEP Encryption: 64 bits and 128 bits. First, 64 bit WEP and 40 bit WEP are the same encryption method and can interoperate in the wireless network. This lower level of WEP encryption uses 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 64 bits (40 + 24). Some vendors refer to this level of WEP as 40 bits and others refer to this as 64 bits. ASUS WLAN products use the term 64 bits when referring to this lower level of encryption. Chapter 3 Windows Settings Second, 104 bit WEP and 128 bit WEP are the same encryption method and can interoperate in the wireless network. This higher level of WEP encryption 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 together makes 128 bits (104 + 24). Some vendors refer to this level of WEP as 104 bits and others refer to this as 128 bits. ASUS WLAN products use the term 128 bits when referring to this higher level of encryption. Click Apply to save and activate the new configurations.

Glossary Access Point (AP) An 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 Hoc A wireless network composed solely of stations within mutual communication range of each other (no Access Point). Basic Rate Set This option allows you to specify the data transmission rate. Basic Service Area (BSS) A set of stations controlled by a single coordination function. Broadband A type of data transmission in which a single medium (such as cable) carries several channels of data at once. Channel An 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. Chapter 5 Glossary Client A 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 specifically 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 lowerspeed 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 reflection recovery, thanks to its encoding scheme and error correction. ASUS WLAN Card 63 Chapter 5 - Glossary Each 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 specifies 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 Key This 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 Pass Phrase is compatible with other ASUS WLAN products. The Pass Phrase option is not as secure as manual assignment. Device Name Also known as DHCP client ID or network name. Sometimes provided by an ISP when using DHCP to assign addresses. DHCP (Dynamic Host Configuration 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. Chapter 5 Glossary 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. Direct-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. 64 ASUS WLAN Card Chapter 5 - Glossary 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 predefined 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 specifications. 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. Encryption This 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 (BSSs) and integrated local area networks (LANs) can be configured as an Extended Service Set. ESSID (Extended Service Set Identifier) Chapter 5 Glossary You must have the same ESSID entered into the gateway and each of its wireless clients. The ESSID is a unique identifier for your wireless network. Ethernet The 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 segment share total bandwidth. Ethernet networks operate at 10Mbps using CSMA/CD to run over 10-BaseT cables. ASUS WLAN Card 65 Chapter 5 - Glossary Firewall A firewall determines which information passes in and out of a network. NAT can create a natural firewall 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 files. Gateway A network point that manages all the data traffic of your network, as well as to the Internet and connects one network to another. IEEE The 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 802.11 IEEE 802.xx is a set of specifications for LANs from the Institute of Electrical and Electronic Engineers (IEEE). Most wired networks conform to 802.3, the specification for CSMA/CD based Ethernet networks or 802.5, the specification for token ring networks. 802.11 defines 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 specifies a carrier sense media access control and physical layer specifications 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 2.4GHz ISM (Industrial, Scientific and Medical) band using direct-sequence spreadspectrum 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 office environments. Chapter 5 Glossary 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). The 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. 66 ASUS WLAN Card Chapter 5 - Glossary 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 significantly 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 specification allocates the 2.4 GHz frequency band into 14 overlapping operating Channels. Each Channel corresponds to a different set of frequencies. IEEE 802.11g Chapter 5 Glossary 802.11g 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. Infrastructure A 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 traffic in the immediate neighborhood. IP (Internet Protocol) The TCP/IP standard protocol that defines 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. ASUS WLAN Card 67 Chapter 5 - Glossary IP Address An IP address is a 32-bit number that identifies each sender or receiver of information that is sent across the Internet. An IP address has two parts: the identifier of a particular network on the Internet and an identifier of the particular device (which can be a server or a workstation) within that network. ISM Bands (Industrial, Scientific, 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 defined geographical area. The benefits include the sharing of Internet access, files 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) Chapter 5 Glossary 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. Packet A basic message unit for communication across a network. A packet usually includes routing information, data, and sometimes error detection information. Pass Phrase The Wireless Settings utility uses an algorithm to generate four WEP keys based on the typed combination. 68 ASUS WLAN Card Chapter 5 - Glossary PCMCIA (Personal Computer Memory Card International Association) The Personal Computer Memory Card International Association (PCMCIA), develops standards for PC cards, formerly known as PCMCIA cards. These cards are available in three types, and are about the same length and width as credit cards. However, the different width of the cards ranges in thickness from 3.3 mm (Type I) to 5.0 mm (Type II) to 10.5 mm (Type III). These cards can be used for various functions, including memory storage, land line modems and wireless modems. 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. Preamble Allows 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 Identifier) Chapter 5 Glossary 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. Station Any device containing IEEE 802.11 wireless medium access conformity. Subnet Mask A subnet mask is a set of four numbers configured like an IP address. It is used to create IP address numbers used only within a particular network. ASUS WLAN Card 69 Chapter 5 - Glossary TCP (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 certifies 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 fixes to WEP such as Weak IV (Initialization Vector) filtering 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 significant 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 Config service is needed. Users can download the Windows XP WPA patch here: http://microsoft.com/downloads/details.aspx?FamilyId=009D8425-CE2B-47A4-ABEC-274845DC9E91&displaylang=en Please note that this patch requires the installation Windows XP Service Pack 1, which is available here: http://www.microsoft.com/WindowsXP/pro/downloads/servicepacks/ sp1/default.asp Chapter 5 Glossary For earlier Windows Operating systems, a WPA capable supplicant is required such as Funk Software's Odyssey Client.
