We recommend this mode for devices running on battery power. Others Encryption Click this link to show the "Encryption" tab. Advanced Click this link to show the "Advanced" tab. In most cases, the default values do not have to be changed. Config - Advanced Click Advanced link on Config-Basic page to show this tab. This tab allows you to set up additional parameters for the wireless Adapter. We recommend using the default values for all items in this window. RTS Threshold (0-234) The RTS/CTS (Request to Send/Clear to Send) function is used to minimize collisions among wireless stations. When RTS/CTS is enabled, the router refrains from sending a data frame until another RTS/CTS handshake is completed. Enable RTS/CTS by setting a specific packet size threshold. The default value (2347) is recommended. Fragmentation Threshold (26-2346) Fragmentation is used to divide 802.11 frames into smaller pieces (fragments) that are sent separately to the destination. Enable fragmentation by setting a specific packet size threshold. If there is an excessive number of collisions on the WLAN, experiment with different fragmentation values to increase the reliability of frame transmissions. The default value (2346) is recommended for normal use. Frame Bursting Frame Bursting technology improves wireless network efficiency and boosts throughput. 26 ASUS WLAN Adapter Chapter 3 - Software Reference Config - Encryption This page enables you to configure the Wireless LAN Adapter encryption settings. For data confidentiality in a wireless environment, IEEE 802.11 specifies a Wired Equivalent Privacy (WEP) algorithm to offer transmission privacy. The WEP uses keys to encrypt and decrypt data packets. The encryption process can scramble frame bits to avoid disclosure to others. The WPA/WPA2 is improved security system for 802.11 which are developed to overcome the weakness of the WEP protocol. Network Authentication Since there is no precise bound in wireless LANs, the WLAN users need to implement certain mechanism to provide security solution. The Authentication policies in this tab provide protection of different levels such as Open, Shared, WPA-PSK, WPA, WPA2 and WPA2-
PSK. Open - Select this option to make the network operate on Open System mode, which use no authentication algorithm. Open stations and APs can authenticate with each other without checking any WEP Key, even if there is. Shared - Select this option to make the network operate on Shared key mode. In a Share Key Authentication system, four-step exchange of frames is required to validate that the station is using the same WEP Key as the access point. WPA-PSK/ WPA2-PSK - Select this option to enable WPA Pre-Shared Key under Infrastructure mode. It enables communication between your client and APs using WPA-PSK/WPA2-PSK encryption mode. WPA/ WPA2 - The network is operating in IEEE 802.1x authentication mode. This mode is for environments with RADIUS (Remote Access Dial-in User Service). In a RADIUS environment, five Extensible Authentication Protocol
(EAP) are supported, including PEAP, TLS/Smart Card, TTLS, LEAP and Md5-
Challenge. ASUS WLAN Adapter 2
3 r e t p a h C e c n e r e f e R e r a w t f o S S o f t w a r e R e f e r e n c e C h a p t e r 3 Chapter 3 - Software Reference Data encryption For Open and Shared authentication mode, the configuration options of encryption type are Disabled and WEP. For WPA, WPA-PSK, WPA2 and WPA2-PSK authentication mode, Temporal Key Integrity Protocol (TKIP) encryption and Advanced Encryption Standard (AES) encryption are supported. Disabled - Disable the encryption function. WEP - WEP Key is used to encrypt your data before it is transmitted over air. You can only connect and communicate with wireless devices that use the same WEP keys. TKIP - TKIP uses an encryption algorithm method that is more stringent than the WEP algorithm. It also uses existing WLAN calculation facilities to perform encryption. TKIP verifies the security configuration after the encryption keys are determined. AES: AES is a symmetric 128-bit block encryption technique that works simultaneously on multiple network layers. Wireless Network Key This option is enabled only if you select WPA-PSK or WPA2-PSK authentication mode. Select TKIP or AES in the encryption filed as encryption mode to begin the encryption proceed. Note: 8 to 64 characters are required in this field. Wireless Network Key (WEP) This option is configurable only if you enable WEP in Network Authentication field. The WEP Key is a 64 bits (5 byte) or 128 bits (13 byte) Hexadecimal digits which is used to encrypt and decrypt data packets. Key Format You can select to enter Hexadecimal digits (0~9, a~f, and A~F) or ASCII characters to setup keys by defining the Key Format. Key Length For 64 bits encryption, each key contains 10 hex digits or 5 ASCII characters. For 128 bits encryption, each key contains 26 hex digits or 13 ASCII characters. Manual assign WEP keys - When you select this option, 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). 28 ASUS WLAN Adapter Chapter 3 - Software Reference Select one as your Default Key The Default Key field allows you specify which of the four encryption keys is to use for transmitting data over wireless LAN. You can change the default key by clicking on the downward arrow, selecting the number of the key you want to use, and clicking the Apply button. If the access point or station with which you are communicating uses the identical key by the same sequence, you can use any of the keys as the default on your WLAN Adapter. Click the Apply button after you have created the encryption keys, the Wireless Settings Utility uses asterisks to mask your keys. 64/128bits versus 40/104bits There are two levels of WEP Encryption: 64 bits and 128 bits. Firstly, 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. Our Wireless LAN products use the term 64 bits when referring to this lower level of encryption. Secondly, 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. Our Wireless LAN products use the term 128 bits when referring to this higher level of encryption. ASUS WLAN Adapter 29 3 r e t p a h C e c n e r e f e R e r a w t f o S Chapter 3 - Software Reference Config - Authentication This tab allows you to set the security settings to match those of your AP. It is configurable only if you have set Network Authentication to WPA or WPA2 in Config-Encryption tab. Authentication Type The authentication type methods include:
PEAP: PEAP (Protected Extensible Authentication Protocol) authentication is a version of Extensible Authentication Protocol
(EAP). EAP ensures mutual authentication between a wireless client and a server that resides at the network operations center. TLS: TLS (Transport Layer Security) authentication is used to create an encrypted tunnel and achieve server-side authentication in a manner similar to Web server authentication using Secure Sockets Layer (SSL) protocol. This method uses digital certificates to verify the identity of a client and server. TTLS: TTLS authentication uses certificates to authenticate the server, while maintaining similar security properties to TLS such as mutual authentication and a shared confidentiality for session WEP key. Survey - Site Survey Use the Site Survey tab to view statistics on the wireless networks available to the WLAN adapter and their parameters. SSID: The SSID of the available Channel: The channel used by each networks. network. S o f t w a r e R e f e r e n c e C h a p t e r 3 30 ASUS WLAN Adapter Chapter 3 - Software Reference RSSI: The Received Signal Strength Indication (RSSI) transmitted by each network. This information is helpful in determining which network to connect to. The value is then normalized to a dBm value. Security: Wireless network encryption information.

. Troubleshooting The 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 difficulties 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 points Follow the procedure below to configure 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. T r o u b l e s h o o t i n g C h a p t e r 4 44 ASUS WLAN Adapter Chapter - Troubleshooting Cannot connect to a Station (WLAN Adapter) Follow the procedure below to configure 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 strength There 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 configuration before installing the WLAN Adapter driver.

4 r e t p a h C g n i t o o h s e l b u o r T Chapter 6 - Glossary 6. Glossary Access 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 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. 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 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 reflection recovery, thanks to its encoding scheme and error correction. 46 ASUS WLAN Adapter l G o s s a r y C h a p t e r
Chapter 6 - 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 Passphrase is compatible with other WLAN products. The Passphrase 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. 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. ASUS WLAN Adapter 4
r e t p a h C y r a s s o G l Chapter 6 - Glossary 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. 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 (BSS) and integrated local 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 wireless clients. The ESSID is a unique identifier for your wireless network. 48 ASUS WLAN Adapter l G o s s a r y C h a p t e r
Chapter 6 - Glossary 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. Firewall A firewall determines which information passes in and out of a network. NAT can create a natural firewall by hiding a local networks 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 (4Mbits/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 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. 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). ASUS WLAN Adapter 49
r e t p a h C y r a s s o G l Chapter 6 - Glossary 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. 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 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.

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 networks 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. ASUS WLAN Adapter

USB-N13 WLAN Adapter User Manual Configuration - Encryption The Encryption page allows you to set up the encryption settings for your WLAN adapter 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. WEP uses keys to encrypt data packets sent and decrypt data packets received. The encryption process can scramble frame bits to avoid disclosure to others. Wi-Fi Protected Access (WPA) is an improved security system for 802.11 that encrypts data sent over radio waves. WPA is developed to overcome the weakness of the WEP protocol. Network Authentication - Set up authentication for your WLAN adapter. Options are:
Open - Sets the network in the Open System mode that disables authentication protection for the network or use the WEP encryption for the network. Shared - Sets the network in the Shared Key mode that uses the WEP encryption for your network. WPA-PSK/WPA2-PSK - Use the WPA Pre-Shared Key/WPA2 Pre-Shared Key in the Infrastructure mode for authentication. Data Encryption - In the Open and Shared authentication modes, options are:
Disabled and WEP. Disabled - Disables the encryption protection for your WLAN adapter. WEP - Encrypts the data before it is transmitted over the air. You can communicate with wireless devices that use the same WEP keys. In the WPA-PSK and WPA2-PSK authentication modes, options are: Temporal Key Integrity Protocol (TKIP) and Advanced Encryption Standard (AES). TKIP - Dynamically generates unique keys to encrypt data packet. AES - Offers stronger protection and increases the complexity of wireless encryption. It is a symmetric 128-bit block encryption method that works simultaneously on multiple network layers. 16 ASUS Wireless-N Adapter USB-N13 WLAN Adapter User Manual Wireless Network Key (WEP) - This option becomes configurable when you select WEP in the Data encryption field. 64-bit WEP key uses 5 ASCII characters
(10 hexadecimal digits). 128-bit WEP key uses 13 ASCII (26 hexadecimal digits). Key Format - Allows you to select the key format. Manual Assignment (WPA and WPA2)- Allows you to assign WEP Keys manually. Key Length - Allows you to select the key length. For 64bits encryption, each key consists of 10 hexadecimal digits or 5 ASCII characters. For 128bits encryption, each key consists of 26 hexadecimal digits or 13 ASCII characters. Select one as your Default Key - Allows you to select one of the four WEP Keys as the default key. Configuration - Advanced The Advanced page is intended for experienced users to set up additional parameters for the WLAN adapter. We recommend that you keep the default values. RTS Threshold (0-2347) - The Request to Send/Clear to Send (RTS/CTS) function is used to minimize collisions among wireless stations. When RTS/CTS is enabled, the router refrains from sending a data frame until another RTS/CTS handshake is completed. Enable RTS/CTS by setting a specific packet size threshold. The default value (2347) is recommended. Fragmentation Threshold (26-2346) - Fragmentation is used to divide 802.11 frames into smaller pieces (fragments) that are sent separately to the destination. Enable fragmentation by setting a specific packet size threshold. If there is an excessive number of collisions on the WLAN , experiment with different fragmentation values to increase the reliability of frame transmissions. The default value (2346) is recommended for normal use. Preamble Mode - Select the preamble mode. The default value is Auto. ASUS Wireless-N Adapter 17 USB-N13 WLAN Adapter User Manual 5.

Troubleshooting This chapter provides solutions to problems which you may encounter when installing or using the ASUS USB-N13 WLAN adapter. Contact a qualified service technician for assistance if the problem still exists after you have performed the troubleshooting solutions. My WLAN adapter cannot connect to any Access Points. Check if Network Type is set to the Infrastructure mode. Check if the SSID of your WLAN adapter is the same as that of the access point you want to connect to. Check if the Encryption settings of your WLAN adapter are the same as those of the access point you want to connect to. My WLAN adapter cannot connect to a station or WLAN adapter. Check if Network Type is set to the Ad Hoc mode. Check if the SSID of your WLAN adapter is the same as that of the station or the WLAN adapter you want to connect to. Check if the Channel of your WLAN adapter is the same as that of the station or the WLAN adapter you want to connect to. Check if the Encryption settings of your WLAN adapter are the same as those of the station or the WLAN adapter you want to connect to. The connection quality is bad and the signal strength is weak. Keep your WLAN adapter away from microwave ovens and large metal objects to avoid radio interference. Adjust the WLAN adapter antenna. Move your WLAN adapter closer to the access point, station, or WLAN adapter you want to connect to. The TCP/IP protocol does not bind to the WLAN adapter. This occurs when your PC 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 configuration before installing the WLAN adapter driver. ASUS Wireless-N Adapter 19 USB-N13 WLAN Adapter User Manual 7. Glossary Access 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 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. Client A client is the desktop or mobile PC that is connected to your network. 20 ASUS Wireless-N Adapter USB-N13 WLAN Adapter User Manual 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 20MHz wide and is broken up into 52 subchannels, each approximately 300KHz 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. Each subchannel in the COFDM implementation is about 300KHz wide. At the low end of the speed gradient, BPSK (binary phase shift keying) is used to encode 125Kbps of data per channel, resulting in a 6,000Kbps, or 6Mbps, data rate. Using quadrature phase shift keying, you can double the amount of data encoded to 250Kbps per channel, yielding a 12Mbps data rate. And by using 16-level quadrature amplitude modulation encoding 4bits per hertz, you can achieve a data rate of 24Mbps. 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 24Mbps. 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 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. ASUS Wireless-N Adapter 21 USB-N13 WLAN Adapter User Manual 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. 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. 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. 22 ASUS Wireless-N Adapter USB-N13 WLAN Adapter User Manual 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) 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. Firewall A firewall determines which information passes in and out of a network. NAT can create a natural firewall by hiding a local networks 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. ASUS Wireless-N Adapter 23 USB-N13 WLAN Adapter User Manual ICS ICS is used to share one computers Internet connection with the rest of the computers on your network. When this computer is connected to the Internet, all the communications to and from the Internet on your network are sent through this computer which is called the host computer. The rest of the computers can send and receive e-mail messages and access the web as if it were connected directly to the Internet. 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 (4Mbits/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 thats intended to be friendlier to office 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). 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. 24 ASUS Wireless-N Adapter USB-N13 WLAN Adapter User Manual 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 5GHz spectrum from 2.4GHz 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 5GHz 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 11Mbps for direct sequence spread spectrum devices. Under 802.11b, direct sequence devices can operate at 11Mbps, 5.5Mbps, 2Mbps, or 1Mbps. This provides interoperability with existing 802.11 direct sequence devices that operate only at 2Mbps. Direct sequence spread spectrum devices spread a radio signal over a range of frequencies. The IEEE 802.11b specification allocates the 2.4GHz frequency band into 14 overlapping operating Channels. Each Channel corresponds to a different set of frequencies. IEEE 802.11g 802.11g is a new extension to 802.11b (used in majority of wireless LANs today) that broadens 802.11bs 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. ASUS Wireless-N Adapter 2
USB-N13 WLAN Adapter User Manual 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. 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 902MHz, 2.400GHz, and 5.7GHz. 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 networks 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. 26 ASUS Wireless-N Adapter USB-N13 WLAN Adapter User Manual 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. 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. 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. ASUS Wireless-N Adapter 27 USB-N13 WLAN Adapter User Manual 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 60Hz, the AM broadcast radio frequency band is 0.55-1.6MHz, the FM broadcast radio frequency band is 88-108MHz, and wireless 802.11 LANs operate at 2.4GHz. SSID (Service Set Identifier) 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. 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 prod WPA (Wi-Fi Protected Access) 28 ASUS Wireless-N Adapter USB-N13 WLAN Adapter User Manual 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
