Card. For brevity, throughout this manual Wireless LAN Card is used to indicate 802.11a/b/g Combo WLAN Card Mini PCI. Also, the following terms/abbreviations are used interchangeably: • • • Access Point-AP Wireless LAN-WLAN Ethernet network-LAN-network This User’s Manual contains information on how to install and configure your Wireless LAN Card. From now on, we will guide you through the correct configuration steps to get your device up and run. Chapter 1 Introduction This Wireless LAN Card is an IEEE 802.11a/b/g combo radio solution. Users have the flexibility to connect to 802.11a, 802.11b or 802.11g networks effortlessly. The Wireless LAN Card design is based on Atheros WLAN chipset. It supports 802.11a, 802.11b and 802.11g standards to provide maximum data rates of 54 Mbps, 108Mbps (802.11a/g) and 11 Mbps (802.11b). 802.11a/b/g Combo Mini PCI WLAN Card User’s Manual Wireless LAN Basics This section contains some Wireless LAN basics to help you better understand how the products work together to create a wireless network. Local Area Network (LAN ) Simply put, a LAN is a network that exists in a relatively limited area. A network is two or more computers connected together sharing files and peripheral devices such as printers. The Wireless LAN Card allows you to interact with other computers without having to run cables normally associated with networks. This lets you move your computer around while staying connected to your network. There are two ways to use the Wireless LAN Card. One way is to connect directly to one or more Wireless LAN Card equipped computers, forming an Ad Hoc wireless network. The second way is to connect to an Access Point that gives you access to an existing wired LAN, forming an Infrastructure wireless network. Chapter 1 Introduction Wireless Network Topologies The 802.11 standard defines two wireless modes: Infrastructure mode and Ad Hoc mode. Ad Hoc Network An Ad Hoc network offers peer to peer connections between wireless stations that are in range of each other. The stations communicate directly with each other without using an Access Point or any connection to a wired network. This mode is useful for quickly and easily setting up a wireless network anywhere that a wireless infrastructure does not exist or is not required for services. In an Ad Hoc network, all wireless stations must have the same SSID, channel and WEP keys (if enabled) to communicate with each other. Figure 1-1 Ad Hoc Network 802.11a/b/g Combo Mini PCI WLAN Card User’s Manual Infrastructure Network An Infrastructure wireless network consists of at least one Access Point connected to the wired network infrastructure and a set of wireless end stations. The AP acts as a gateway, linking the wireless network to a wired LAN. As a result, wireless stations have access to all of the features of your wired LAN including e-mail, Internet, network printers and files server access. Figure 1-2 Infrastructure Network Roaming Between Multiple Access Points For large environments, multiple Access Points can be implemented to extend the wireless service coverage area for seamless wireless access. It allows wireless clients to roam from one AP to another while maintaining the wireless connectivity at all times. A wireless client Chapter 1 Introduction wandering across multiple APs will automatically change the operating radio frequency as required. In a roaming network, all APs and wireless clients must have the same Service Set Identity (SSID) and security setting (if enabled). Alternatively the mobile station may use an SSID of “any” to associate with any available AP, regardless of the AP’s SSID. Roaming among different Access Points is controlled automatically to maintain the wireless connectivity at all times. Figure 1-3 Roaming Across Multiple Access Points 802.11a/b/g Combo Mini PCI WLAN Card User’s Manual 802.11a, 802.11b and 802.11g As this Wireless LAN Card is an IEEE 802.11a/b/g combo radio solution, you can connect to either an 802.11a, 802.11b or 802.11g network. Getting familiar of some distinguish differences between these two standards will help you better understand your device. • Operating Frequency Band 802.11b and 802.11g operate in the 2.4GHz band while 802.11a operates in the 5GHz band. Therefore, throughout this manual the 2.4 GHz-related terms are referred to 802.11b/g networks while 5 GHz is referred to 802.11a. • Data Rates 802.11b supports data rates of 1, 2, 5.5, and 11 Mbps. 802.11g supports data rates of 1, 2, 5.5, 6, 9,11, 12, 18, 24, 36, 48 and 54Mbps, 108Mbps. 802.11a supports mandatory data rates of 6, 12, and 24 Mbps and optional data rates of 9, 18, 36, and 54 Mbps, 108Mbps. • Modulation 802.11a employs Orthogonal Frequency Division Modulation (OFDM) scheme. 802.11b uses Direct Sequence Spread Spectrum (DSSS) technologies. 802.11g uses Chapter 1 Introduction Complementary Code Keying (CCK) and Orthogonal Frequency Division Modulation (OFDM). Chapter 2 Installing the Driver and Utility Software This chapter describes the first-time installation of the driver and software for the Wireless LAN Card. Proper driver installation is to allow the device to operate on your host computer while the utility software, a Windows program, is to help you configure and monitor your Wireless LAN Card.

Configuration names are not case sensitive. Network Names (SSID): • • 18 Ad Hoc mode: It is the name of the Wireless LAN group you want to create or participate in. This field has a maximum limit of 32 characters. A network name is mandatory for Ad Hoc mode. The SSID for all stations in a single Ad Hoc network must be the same. Enter only one SSID. Infrastructure mode: It is the name of the Wireless LAN group you want to participate in. This field has a maximum limit of 32 characters. You can enter up to three SSID. In an Infrastructure network, the SSID must match on AP and all the wireless clients to communicate with each other. Note that under Access Point mode, if the Network Name (SSID) field is left blank or filled in with the special SSID name “any”, your Wireless LAN Card will connect to the first compatible and “open” AP with the best signal strength within the connection range. It allows your Wireless LAN Card to wander across networks with different SSID. Chapter 3 Utility Configuration Figure 3-1 General tab under the Profile Management Security Tab The Atheros Client Utility provides four types of encryption: Pre-Shared Keys, LEAP, Externally Managed 802.1x Keys and Disabled. Each wireless device within a WLAN must use the same security settings to allow communication. Depending on whether you are connecting to an Ad Hoc or Infrastructure network, you will need to consult one of the workgroup participants or network administrator for the correct security settings. 19 802.11a/b/g Combo Mini PCI WLAN Card User’s Manual Pre-Shared Keys To use this option, enable the Pre-Shared Keys option on the Security tab and click Define Pre-Shared Keys to set the encryption keys. Then configure the fields below: Key Entry Method: Select the method to enter the key. If Hexadecimal is selected, only digits 0-9 and letters a-f, A-F are allowed. If ASCII Text is selected, you can enter alphanumeric characters. Key Length (bit): Defines the length for each encryption key. Key length varies according to the WEP type. As the Key Length is changed, the number of available characters in the field is changed automatically. If an already entered key is too long, the key is automatically truncated to fit. If the key length is increased again, the field does not automatically restore to its previous value. Per-User Key: Defines the unique encryption key for network configuration security. This field must be populated to enable security using a unique key. This key is not used in Ad Hoc mode. Shared Keys (1 ~ 4): Defines a set of shared encryption keys for network configuration security. At least one Shared Key field must be populated to enable security using a shared key. Note: All encryption key fields are displayed only when initially entered. On subsequent entry into the security property page, the field are masked. 20 Chapter 3 Utility Configuration Select the default encryption keys to be used (either Per-User Key or Shared Key). You are only allowed to select one Per-User Key, or one Shared Key 1, Shared Key 2, Shared Key 3, or Shared Key 4 whose corresponding field has been completed. Note: Currently, Windows XP does not support 152-bit encryption when using the built-in Wireless Zero Configuration Utility. You must disable the zero configuration in order to use 152-bit encryption. Figure 3-2 Define Pre-Shared Keys screen 21 802.11a/b/g Combo Mini PCI WLAN Card User’s Manual LEAP (Light Extensible Authentication Protocol) Enables the use of LEAP for dynamic security keys. If you want to connect to a network using Cisco LEAP, make sure to check the LEAP option and enter the User Name and Password used to log in to the network in the provided fields. Note: If you are going to connect to an LEAP network, you should disable Windows XP Wireless Zero Configuration Utility entirely because it is basically incompatible with LEAP. Figure 3-3 Define User Information screen 22 Chapter 3 Utility Configuration Externally Managed 802.1x Keys Windows XP provides native support for 802.1x standard. Its Wireless Zero Configuration Utility allows to set up 802.1x related parameters. However, to use 802.1x function, your wireless station also needs some essential components, such as a certificate from the certificate authority. Please consult with the network administrator for the configuring procedures. If you are using a operating system other than Windows XP, the Define Static Encryption Keys button is available for you to enter at least one key into the Atheros Client Utility static key configuration. In the AP-802.1x network, the static keys serve only to initialize the security data structures. Real keys are dynamically provided by 802.1x key distribution protocol.

Make sure all the stations in the Ad Hoc network are set with the same SSID. You can set up one station to start the Ad Hoc network and wait briefly before setting other stations. This prevents several stations from trying to establish a network at the same time, which can result in multiple singular networks being established, rather than a single network with multiple stations associated to it. If you are in the Europe using ETSI regulatory domain, Ad Hoc mode is not supported. My station cannot access network resources in Infrastructure mode. Even your link status indicates a successful connection with the Access Point, this connection applies to the “physical” network layer only. It is just like pulling a cable between two wired computers. To access the network resource, you will need a login name and login password as implemented by most of network operating systems. You should consult with your network administrator for required settings. 50 Chapter 7 Troubleshooting Radio Interference You may be able to eliminate any interference by trying the following: • • • • Increase the distance between the wireless computers and the device causing the radio interference. Plug the computer equipped with the Wireless LAN Card into an outlet on a different branch circuit from that used by the affecting device. Consult the dealer or an experienced radio technician for help. For 802.11b connection, keep the computer with the Wireless LAN Card away from the microwave oven and large metal objects. Cannot Connect to Another Wireless LAN Card If you cannot make a connection to another Wireless LAN Card from your computer, it could be due to one of the following reasons: • • Incorrect SSID. Make sure the SSID is the same for all computers that have a Wireless LAN Card. Changes are not being recognized by your computer. Restart your computer. 51 802.11a/b/g Combo Mini PCI WLAN Card User’s Manual • • If in Ad Hoc mode, make sure the Log on to Windows NT domain check box is not selected in the Client for Microsoft Networks Properties dialog box in the Network Configuration tab. Incorrect IP address or subnet mask. Check these settings in the TCP/IP Properties dialog box in the Network Configuration tab. Poor Link Quality If the link quality display stays in the poor range, it could be due to one of the following reasons: • • • Radio interference. For 802.11b/g 2.4 GHz band, possible sources of interference can be microwave ovens, cordless phones or pager systems. Identify and eliminate the source of interference. Although 802.11a 5 GHz band has less interference, the signals have a higher absorption rate and may be blocked by walls or other building structures. Move your device closer to your target Access Point or wireless station. Distance between Wireless LAN Card and Access Point is too far. Decrease the distance between the Access Point or another wireless adapter. Cannot Connect to an Access Point 52 Chapter 7 Troubleshooting If you cannot make a connection to an Access Point, it could be due to one of the following reasons: • • • Make sure the Wireless LAN Card and the Access Point have no physical connection problems. Make sure the SSID for the Wireless LAN Card is the same as the Access Point. Make sure the security setting is the same as that of the Access Point. Also, make sure the default key is the same for both the Wireless LAN Card and the Access Point. 53 Appendix A Setting Up TCP/IP This section contains instructions for configuring the TCP/IP protocol of the Wireless LAN Card. The IP address policy depends on your network. You should configure your TCP/IP protocol as instructed by your network administrator. For Windows 2000/XP 1.

Appendix A Setting Up TCP/IP Federal Communication Commission Interference Statement This equipment has been tested and found to comply with the limits for a Class B digital device, pursuant to Part 15 of the FCC Rules. These limits are designed to provide reasonable protection against harmful interference in a residential installation. This equipment generates, uses and can radiate radio frequency energy and, if not installed and used in accordance with the instructions, may cause harmful interference to radio communications. However, there is no guarantee that interference will not occur in a particular installation. If this equipment does cause harmful interference to radio or television reception, which can be determined by turning the equipment off and on, the user is encouraged to try to correct the interference by one of the following measures: - Reorient or relocate the receiving antenna. - Increase the separation between the equipment and receiver. - Connect the equipment into an outlet on a circuit different from that to which the receiver is connected. - Consult the dealer or an experienced radio/TV technician for help. This device complies with Part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. FCC Caution: Any changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate this equipment. "Askey declare that WLL4070 is limited in CH1~CH11 by specified firmware controlled in USA." 57 802.11a/b/g Combo Mini PCI WLAN Card User’s Manual IMPORTANT NOTE: FCC Radiation Exposure Statement: This equipment complies with FCC radiation exposure limits set forth for an uncontrolled environment. To maintain compliance with FCC RF exposure compliance requirements, please avoid direct contact to the transmitting antenna during transmitting. This equipment should be installed and operated with minimum distance 20cm between the radiator & your body. This device is intended only for OEM integrators under the following conditions: 1) The antenna must be installed such that 20 cm is maintained between the antenna and users, and 2) The antenna should be integral if the end device is intended to be operated in 5.15 ~ 5.25GHz frequency range. As long as 2 conditions above are met, further transmitter test will not be required. However, the OEM integrator is still responsible for testing their end-product for any additional compliance requirements required with this module installed (for example, digital device emissions, PC peripheral requirements, etc.). IMPORTANT NOTE: In the event that these conditions can not be met (for example certain laptop configurations or co-location with another transmitter), then the FCC authorization is no longer considered valid and the FCC ID can not be used on the final product. In these circumstances, the OEM integrator will be responsible for re-evaluating the end product (including the transmitter) and obtaining a separate FCC authorization. 58 Appendix A Setting Up TCP/IP End Product Labeling This transmitter module is authorized only for use in device where the antenna may be installed such that 20 cm may be maintained between the antenna and users (for example: Notebook). The final end product must be labeled in a visible area with the following: “Contains TX FCC ID:H8NWLL4070”. Manual Information That Must be Included The OEM integrator has to be aware not to provide information to the end user regarding how to install or remove this RF module in the users manual of the end product which integrate this module. The users manual for OEM integrators end users must include the following information in a prominent location “ IMPORTANT NOTE: To comply with FCC RF exposure compliance requirements, the antenna used for this transmitter must be installed to provide a separation distance of at least 20 cm from all persons and must not be co-located or operating in conjunction with any other antenna or transmitter”. If the end product integrating this module is going to be operated in 5.15 ~ 5.25GHz frequency range, the warning statement in the user manual of the end product should include the restriction of "operating this device outdoors could void the user’s authority to operate the equipment". 59 802.11a/b/g Combo Mini PCI WLAN Card User’s Manual IC Statement Operation is subject to the following two conditions: 1) this device may not cause interference and 2) this device must accept any interference, including interference that may cause undesired operation of the device To prevent radio interference to the licensed service (i.e. co-channel Mobile Satellite systems) this device is intended to be operated indoors and away from windows to provide maximum shielding. Equipment (or its transmit antenna) that is installed outdoors is subject to licensing. Because high power radars are allocated as primary users (meaning they have priority) in 5250-5350 MHz, these radars could cause interference and/or damage to license exempt LAN devices. "This device has been designed to operate with an antenna having a maximum gain, please refer to below antenna table.
