PCI Wireless LAN Card. For brevity, throughout this manual Wireless LAN Card is used to indicate 802.11g WLAN Card Mini PCI. Also, the following terms/abbreviations are used interchangeably:
Access Point-AP Wireless LAN-WLAN Ethernet network-LAN-network This Users 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. v Chapter 1 Introduction The Wireless LAN Card design is based on Atheros WLAN chipset. It supports 802.11g standards to provide maximum data rates of 54 Mbps. 7 802.11g Mini PCI WLAN Card Users 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. 8 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. Chapter 1 Introduction Figure 1-1 Ad Hoc Network 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 9 802.11g Mini PCI WLAN Card Users Manual 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 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 APs 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 802.11g This Wireless LAN Card is an IEEE 802.11g radio solution. Getting familiar with some technical terms will help you better understand your device. Operating Frequency Band Operates in the 2.4GHz band . Data Rates Supports data rates of 1, 2, 5.5, 6, 9,11, 12, 18, 24, 36, 48 and 54Mbps. Modulation Complementary Code Keying (CCK) and Orthogonal Frequency Division Modulation (OFDM). 10 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. Note: This Mini PCI model is an integrated Wireless LAN Card solution, your laptop computer is probably shipped with its driver and software properly installed. If this is the case, ignore this chapter and proceed with the configuration steps in the next chapter. In case you need to re-install the driver and software for any reason, we recommend that you remove any previously installed driver and software from your system first. Refer to the section Chapter 6 Uninstalling the Wireless LAN Card for the instructions on how to remove previous driver releases. 11 802.11g Mini PCI WLAN Card Users Manual System Requirements To use the Wireless LAN Card, your computer must meet the following minimum requirements:

Network Basic Configuration To add a new Ad Hoc or Infrastructure profile, click New on the Profile Management tab. The dialog box displays three tabs: General, Security and Advanced. General Tab The configuration items on the General tab are described as below. Profile Name: Enter a unique name to identify this network setting. Configuration names are not case sensitive. Network Names (SSID):
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. 18 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. 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. 19 802.11g Mini PCI WLAN Card Users Manual Note: All encryption key fields are displayed only when initially entered. On subsequent entry into the security property page, the field are masked. 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 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 20 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. Figure 3-4 Security tab under the Profile Management Advanced Tab The configuration items on the Advanced tab are described as below. Power Save Mode: Infrastructure mode ONLY. This feature reduces power consumption by the Wireless LAN Card to extend the battery life of your computer. The options include Off, Normal and Maximum. Off The power management is disabled and the card consumes full power from the computer. Normal The driver turns off power to the adapter for brief periods over briefly spaced time intervals. Maximum The driver turns off power to the adapter for longer periods over more widely spaced time intervals. The guideline for choosing Normal or Maximum:
The card wakes up more often and responds sooner to network requests in Normal mode than in Maximum mode. Maximum mode consumes less power than Normal mode. Network Type: Select Ad Hoc or Access Point. 21 802.11g Mini PCI WLAN Card Users Manual 802.11b Preamble: The preamble is part of the IEEE 802.11b physical layer specification. All 802.11b devices are mandatory to support the long preamble format, but may optionally support the short preamble. This Wireless LAN Card supports the short preamble. The default Short & Long option allows communication with other 802.11b devices which support short preamble to boost the throughput. If your device is having trouble to communicate with other 802.11b devices, you may try to select the Long Only option. Transmit Power Level: Specifies the transmit power to be used. Reducing the transmit power level conserves battery power but decreases radio range. Wireless Mode: Specifies the wireless operation mode. The Wireless LAN Card will scan the radio signals only in the base band you specified. You can check all for your convenience. 2.4 GHz 11 Mbps: Specifies whether to use 11 Mbps mode. 2.4 GHz 54 Mbps: Specifies whether to use 54 Mbps mode.

Chapter 7 Troubleshooting Chapter 7 Troubleshooting My station cannot associate in Ad Hoc mode. 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. 41 802.11g Mini PCI WLAN Card Users Manual 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. 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. Possible sources of interference can be microwave ovens, cordless phones or pager systems. Identify and eliminate the source of interference. 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 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. 42 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. Chapter 7 Troubleshooting 43 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.
