Click Search Now. A few files matching these criteria are possible, if previous drivers have not been removed properly. Choose the files that have been found and delete them from the system. 2-14 4. To complete the uninstallation, ar5210b.sys should also be removed from the \WINNT\system32\drivers folder. 2-15 Device Configuration Configuration of the D-Link DWL-A520 Wireless Network Adapter can be done through the Network Control Panel (NCP) in adapter properties. You can set the Wireless Network Adapter to work in one of two modes, either infrastructure mode (which leverages an AP) or ad hoc mode (which consists of a group of stations participating in the WLAN). In infrastructure mode, the Wireless Network Adapter participates in a basic service set (BSS) as a station, and communicates with the other stations through an AP, as illustrated in Figure 2-1. STA2 STA1 AP Ethernet Figure 2-1. Infrastructure Mode 2-16 In ad hoc mode, a Wireless Network Adapter works within an independent basic service set (IBSS), as illustrated in Figure 2-2. All stations communicate directly with other stations without an AP. STA1 STA3 STA2 STA5 STA4 Figure 2-2. Ad Hoc Mode To configure the DWL-A520 Wireless Network Adapter:
1. In the Device Manager, right-click D-Link DWL-A520 Wireless Network Adapter, and click Properties to access the properties of the adapter. 2-17 2. Configuration additions, modifications, and deletions are made under the Settings tab of the D-Link DWL-A520 Wireless Network Adapter properties. 3. Select one of the configurations under the configuration list, and click Modify to show the Network Configuration Settings screen. This property sheet has two pages: General and Security. The General page has the following fields:
Configuration Name: This field identifies the configuration. This name must be unique. Configuration names are case insensitive. Network Name (SSID): This is the name of the IEEE 802.11a wireless network, for example, D-Link 802.11a Wireless Network. This field has a maximum limit of 32 characters. Network Connection: This field defines whether the STA is configured for an ad hoc or infrastructure network. 2-18 Power Saving: This field allows the configuration of power management options. The options are Off, Normal, and Maximum. Power management is disabled when ad hoc mode is selected in the Network Connection field. When the Power Saving setting is Off, the adapter receives full power from the PC. When the Power Saving setting is Normal, the driver turns off power to the adapter for brief periods over briefly-spaced time intervals. When the Power Saving setting is Maximum, the driver turns off power to the adapter for longer periods over more widely-spaced time intervals. Turbo Mode: This field enables or disables D-Link turbo mode. Locally Administered Address: This field defines the locally administered MAC address (LAA). To enter a value in the address field, the check box needs to be selected. Typically, an LAA is not required, because the driver automatically loads a unique, globally administered address from the EEPROM. 4. The next tab on this property sheet allows for the selection of security features. The fields on this page are as follows:
Enable Security: This field completely enables or disables the IEEE 802.11 wired equivalent privacy (WEP) security feature. Default Encryption Key: This field defines the type of encryption key to use (either Unique Key or Shared Keys). This field allows you to select only a key (Unique, First, Second, Third, or Fourth) whose corresponding field has been completed. 2-19 Unique Key: This field defines the unique encryption key for security for the current network configuration. In ad hoc mode, this encryption key type is not used. To enable security using a Unique Key, this field must be populated. Shared Keys: These fields define a set of shared encryption keys. To enable security using Shared Keys, at least one Shared Key field must be populated. Key Length: This field defines the length for each encryption key. As the Key Length is changed, the number of available characters in the field is changed automatically. If after a key is entered the length is adjusted to a smaller number, the key is automatically truncated to fit. If the length is increased again, the field is not automatically updated to its previous value. All encryption key fields are displayed only when initially entered. On subsequent entry into the security property page, the fields are masked. The keys must be entered as hexadecimal digits. 2-20 Infrastructure Mode To configure an D-Link DWL-A520 Wireless Network Adapter in infrastructure mode:
1. Ensure that the Locally Administered Address checkbox is unchecked. 2. Choose the following settings:
Configuration Name: This field identifies the configuration. This name must be unique. Configuration names are case insensitive. Network Name (SSID): This is the name of the IEEE 802.11a wireless network, for example, D-Link 802.11a Wireless Network. This field has a maximum limit of 32 characters. If this field is left blank, the STA connects to the AP with the best signal strength. Network Connection: AP (infrastructure). Power Saving: This field allows the configuration of power management options. The options are Off, Normal, and Maximum. Turbo Mode: This field enables or disables D-Link turbo mode. Locally Administered Address: This field defines the locally administered MAC address (LAA). To enter a value in the address field, the check box needs to be selected. 2-21 Usually infrastructure mode is used in an enterprise environment where APs are installed and maintained by corporate IT staff. Much of the data in the enterprise network is confidential. It is important to configure security to make sure only stations with appropriate keys can receive sensitive data. The D-
Link DWL-A520 Wireless Network Adapter and NDIS driver support key lengths of 40 bits, 104 bits, and 128 bits. Typically, the appropriate encryption and decryption keys are supplied by the corporate IT staff. Ad Hoc Mode An ad hoc network usually is a short-lived network with a small number of stations. The network is usually created for a special purpose such as exchanging data between friends, or between customer and client. Because the duration of the ad hoc network tends to be limited, Power Saving and Security features are not typically a requirement. For ad hoc network activity, the Power Saving and Security features can be disabled. Currently, shared key security is supported in ad hoc mode. Future D-Link software implementations will provide unique key support. In ad hoc mode, a station scans the air for an existing BSS.

Therefore, the D-Link NDIS driver installation uses an approach that is different from the installation used in other Operating Systems. In order to install D-Link DWL-A520 Wireless Network Adapter in Windows NT 4.0 with Service Pack 6, a PC Card utility called CardWizard is used. If your computer system does not have CardWizard utility pre-loaded, then you can purchase it from SystemSoft Corporation (www.systemsoft.com) or you can download a 14-day evaluation copy from ftp://www.systemsoft.com/pub/Wn51tren.exe. Note that CardWizard requires Windows NT 4.0 Build 1381 (Service Pack 6) installed in order to function correctly. Please install Service Pack 6 if your Windows NT 4.0 is not updated. After CardWizard utility is loaded, insert the D-Link DWL-A520 Wireless Network Adapter into a 32-bit CardBus slot, and follow these steps to install the NDIS driver:
1. CardWizard will detect the insertion of the D-Link CardBus card and show the following screen. Click Correct to continue. 6-1 2. Click OK to continue. 3. Windows NT 4.0 Network Properties windows displays. Click Add to continue. 6-2 4. Click Have Disk. 5. Manually enter the location of where the D-Link NDIS 4.0 driver is located. For example, D:\NDIS\BIN\PRODUCTION\NDIS4. Click OK to continue. 6-3 6. Make sure D-Link DWL-A520 Wireless Network Adapter is selected. Click OK to continue. 7. Set Map Registers, QoS, and Transmit Power Control to default values and click OK. 6-4 8. Windows NT 4.0 binds TCP/IP protocol to D-Link DWL-A520 Wireless Network Adapters and TCP/IP properties have to be entered. Depending on the type of network the station connects to, Gateway and DNS Configuration information may also be required. IP configuration information (DHCP or assigned IP address, Gateway and DNS server IP addresses) is usually obtained from the corporate IT staff. For a simple demonstration, the station is assigned a static IP address. Choose Specify an IP address and enter an IP address and subnet mask. Assigning an IP address and subnet mask allows the station to interact with the AP or other stations in the same IP subnet. Click OK to complete the TCP/IP configuration. 6-5 9. Restart the system for the changes to take effect. Device Configuration Configuration of the D-Link DWL-A520 Wireless Network Adapter can be done through the D-Link NIC Configuration Control Panel applet provided by D-Link. Similar to Windows 2000, the device can be set to work in one of two modes, either infrastructure mode or ad hoc mode. See Section Device Configuration beginning on page 2-16 for more details on these network connection types. Start D-Link NIC Configuration utility from the Control Panel. 6-6 Select one of the configuration(s) under the configuration list and click Modify or click New, and follow the Section Infrastructure Mode on page 6-7 and Section Ad Hoc Mode on page 6-10 to set up the station to work in infrastructure mode and ad hoc mode. Infrastructure Mode This section defines the process of configuring an D-Link DWL-A520 Wireless Network Adapter in infrastructure mode. Refer to Section Device Configuration beginning on page 2-16 for detailed descriptions of each option in the Network Configuration Settings. 1. Under the General tab, make sure the Locally Administered Address checkbox is unchecked. Use the following information as a guideline to choose the values of each field in the configuration window:
Configuration Name: This field identifies the configuration. This name must be unique. Configuration names are case insensitive. For example, AP. 6-7 Network Name (SSID): This is the name of the IEEE 802.11a wireless network. For example, D-Link_AP. This field has a maximum limit of 32 characters. If this field is left blank, the STA will connect to the AP with the best signal strength. Network Connection: AP (Infrastructure). Power Saving: This field allows the configuration of power management options. The options are Off, Normal, and Maximum. Turbo Mode: This field enables or disables D-Link Turbo mode. 6-8 Usually, infrastructure mode is used in an enterprise environment where APs are installed and maintained by corporate IT staff. Much of the data in the enterprise network is confidential. It is important to configure security to make sure only stations with appropriate keys can receive sensitive data. The D-Link DWL-A520 Wireless Network Adapter and NDIS driver support key lengths of 40-bits, 104-bits and 128-bits. Typically, the appropriate encryption and decryption keys will be supplied by the corporate IT staff. 6-9 Ad Hoc Mode This section defines the process of configuring an D-Link DWL-A520 Wireless Network Adapter in ad hoc or IBSS mode. Refer to Section Ad Hoc Mode on page 2-22 for detail descriptions of ad hoc operation. 1. Similar to the set up of AP Infrastructure mode described in the previous section, ad hoc mode is also configured by changing the options in Network Configuration Settings window. Use the following information as a guideline to choose the values of each field in the configuration window:
Configuration Name: This field identifies the configuration. This name must be unique. Configuration names are case insensitive. For example, Ad Hoc. Network Name (SSID): A Network Name is mandatory for ad hoc mode. The SSID for all stations in a single ad hoc network must be the same. Network Connection: Ad Hoc. Power Saving: Power saving mode is not currently supported in an ad hoc network. Turbo Mode: All stations participating in the ad hoc network must have the same rate setting. Locally Administered Address: This field defines the locally administered MAC address (LAA). To enter a value in the address field, the check box needs to be selected. 6-10 2. You may optionally set up security features, but it is not typically a requirement, since the duration of the ad hoc network tends to be limited. Currently, only shared key security is supported in ad hoc mode. Future D-Link software implementations will provide unique key support. 6-11 3. In ad hoc mode, a station will scan the air for an existing BSS. If no BSS is found, the station will establish a BSS for other stations to join. When other stations scan the air and find an established BSS in place, they join that BSS to form an ad hoc network. If a specific set of stations requires ad hoc network connectivity, it is recommended to have one station establish a BSS first before configuring the remaining stations. This will prevent the scenario of several stations trying to form a BSS at the same time, which may result in multiple singular BSSs being established rather than a single BSS with multiple stations. Verify Connection You may use LinkMon utility to monitor the operating status of D-Link DWL-
A520 Wireless Network Adapter once the STA is connected. Please refer to Chapter 7 for descriptions of LinkMon utility. If the STA is configured properly then you will be able to perform ping test as well as other network applications that a wired Ethernet device can perform. 1. Choose Start > Programs > Accessories > Command Prompt to open the command prompt window. Type ipconfig to determine if the TCP/IP configuration has taken effect. To test IP connectivity in ad hoc or infrastructure mode, use the ping <ipaddress> command. 6-12 2. To map the drive on another machine to your computer, right-click My Computer and click Map Network Drive. 3. Specify the path of a network-shared folder. 4. After mapping the drive, you can perform file transfers, video streaming, and all other network data transfers that are normally performed with wired 10/100 Ethernet connections. 6-13 Driver Uninstallation This section provides uninstallation procedures for removing the D-Link NDIS driver from the system. 1. To remove the NDIS driver from the system, go to Control Panel and open Network properties. 6-14 2. Under the Adapters tab, choose D-Link DWL-A520 Wireless Network Adapter and click Remove. 3. Click OK to confirm the removal of the D-Link DWL-A520 Wireless Network Adapter. 6-15 4. D-Link DWL-A520 Wireless Network Adapter is no longer listed under the Adapters tab. Click Close to continue. 5. Restart the system to complete the un-installation of D-Link NDIS 4.0 driver. 6-16 Installation 7 LinkMon LinkMon is a Graphical User Interface (GUI) program that provides detailed operational status and statistics for the D-Link DWL-A520 Wireless Network Adapter. The LinkMon executable file, linkmon.exe, is included on the D-Link Release Version Error! Reference source not found. CD, and is in the folder
\ndis\bin\production\. Copy this file from the CD to a local drive for execution. Since Windows 98 SE does not have native support for WMI, which is required to make LinkMon work correctly, an upgrade from Microsoft is needed. Use the procedures described in the following section to acquire and install the necessary WMI module from Microsoft. This is only required for Windows 98 SE installations. 1. Download WMI installer from Microsoft (wmi9x.exe) and save it to your hard disk. 2. Execute WMI installer by double-clicking wmi9x.exe. 7-1 3. Click Next to continue. 4. Click I accept this agreement and then click Next to continue. 7-2 5. Click Next to continue. 6. The installer now installs files to the SYSTEM directory. 7. The system must be rebooted for the WMI installation files to become effective. When the system completes the rebooting process, launch LinkMon. 7-3 Features There are five tabs in LinkMon used to display STA information:
General tab
Frame Statistics tab
Transmit Retries tab
Station tab
Driver tab Under the General tab of the LinkMon program property sheet is general information about the program and its operations. Under the Frame Statistics tab is statistical information showing the number of frames being sent and received, retry count on frames sent, frame checksum error counts for received frames, and receive signal strength indicator (RSSI) information. These fields are described in the Station Programmers Guide under Appendix A as OIDs. LinkMon supports most of the OIDs listed in that section. 7-4 Under the Transmit Retries tab is detailed transmit retry statistical information for transmitted frames. 7-5 Under the Station tab is detailed BSS information including SSID, BSSID, association status, operating channel frequency, and information about scanned APs. Under the Driver tab is statistical data pertaining to NDIS driver operation. 7-6 The Action menu enables a NDIS driver unloading and reloading, and network interface card (NIC) reset. Note that driver unload option is not available in Windows Me, Windows 98SE, and Windows NT 4.0. NIC reset is also not available in Windows NT 4.0. On the Options menu, choose Settings. 7-7 Under the Display tab, you can select the data display modes of Cumulative or Relative. Cumulative mode displays statistical LinkMon data collected from the beginning of driver load. Relative mode displays differences in the statistical data since the last update. Under the Log File tab, the logging function can be enabled to log to a file the statistical information collected by the LinkMon utility, for later reference or post processing by an application such as Microsoft Excel. 7-8 8 RFSilent This chapter describes the RFSilent application that allows you to enable or disable the RF Signal (radio) on all D-Link STA Reference Designs. The RFSilent is a Windows-based application that appears in the right-hand corner of your Windows taskbar. System Requirements The RFSilent application communicates with most Windows applications using Windows Management Instrumentation (WMI). For Windows NT 4.0, RFSilent communicates through the Input and Output Control (IOCTL) mechanism. If you are using Windows 98SE, WMI does not come pre-installed and you must install it prior to using RFSilent. Refer to the following procedure to acquire and install the required WMI module from Microsoft. Windows 98SE Environment If you want to use the RFSilent application in a Windows 98SE environment, you must install WMI. Follow these steps to install WMI:
1. Download the WMI installer (wmi9x.exe) from Microsoft and save it to your hard disk. 2. Execute the WMI Installer by double-clicking wmi9x.exe. 3. Click Next to continue. 4. Click I accept this agreement and then click Next to continue. 8-1 5. Click Next to continue. The installer now copies the necessary files to the SYSTEM directory. 6. Reboot the system. RFSilent Setup The RFSilent application allows you to enable or disable D-Link STA References Designs. You can enable or disable the RFSilent application through user-defined settings. Refer to a description of driver parameters in the AP Programmers Reference Guide. Operation The RFSilent application is a Windows-based application that, once enabled, appears as an icon (RF) in the right-hand corner of your Windows taskbar
(see Figure 8-1). You can automatically launch RFSilent at system boot-up by entering a shortcut statement in the Startup folder. Figure 8-1.

Read the following descriptions if you are having problems. If you cannot find an answer here, please contact an D-Link field application engineer for assistance. 1. My computer does not recognize the D-Link CardBus reference card. Make sure the CardBus card is properly inserted into a 32-bit CardBus slot. If Windows does not detect the hardware upon insertion of the card, the system could have a previous D-Link NDIS driver installed. Remove the old driver and try again. 2. The D-Link DWL-A520 Wireless Network Adapter does not work properly after the driver is installed. Re-insert the CardBus card into the slot. A beep should be heard if the adapter is properly inserted. Go to Device Manager and make sure the D-Link DWL-A520 Wireless Network Adapter exists under the network adapters device node. If you see the yellow exclamation mark then there are conflicting resources. In this case, make sure the computer system has a free IRQ and make sure you have installed the proper driver. Uninstall the driver, restart the system, and repeat the driver installation steps if necessary. 3. Stations cannot associate in ad hoc mode. Make sure the same service set identifier is specified for all stations that need to join the same ad hoc network. Set up one station to establish a BSS and wait briefly before setting up other stations. This prevents several stations from trying to establish a BSS at the same time, which can result in multiple singular BSSs being established, rather than a single BSS with multiple stations associated to it. 9-1 4. The station cannot access the Internet in the infrastructure configuration. Make sure the station is associated and joined with the AP. If Wired Equivalent Privacy (WEP) security is enabled on the AP, the station must have the proper WEP keys specified. Also make sure TCP/IP properties are correctly configured. 9-2 A Channel and Data Rate Selection This section provides basic information for selecting fixed data rate and channel frequency in the NDIS driver. This becomes necessary if you want to test the D-Link Wireless Network Adapter at a specific channel with the rate adaptation controls turned off. To select channel frequency and data rate in the Windows environment with NDIS driver installed:
1. Choose Start > Run, and type regedit to open Registry Editor. 2. For Windows 2000 and Windows XP, locate the following registry key, and select Find from the Edit menu:
HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\
For Windows 98SE and Windows Me, locate the following registry key, and select Find from the Edit menu:
HKEY_LOCAL_MACHINE\System\CurrentControlSet\
3. Type clist and click Find Next to find the registry key. Note that if you have multiple instances of the D-Link Wireless Network Adapter installed, for example, the NDIS driver is installed more than once, then you will need to click Find Next to locate the current instance of the device that is in use. 4. Double-click on clist and enter the channel number in the Value Data field. Enter the IEEE channel number from the following table. For example, enter 40 to select channel frequency of 5.20 GHz. The channel numbers follow the IEEE format where:
Channel Frequency (in GHz) = 5 + 0.005 * (Channel Number) Channel Number Channel Frequency Regulator Domain 26 28 30 32 34 36 38 40 42 44 46 48 50 52 54 56 58 60 62 64 66 68 70 72 74 76 78 80 5.13 GHz 5.14 GHz 5.15 GHz 5.16 GHz 5.17 GHz 5.18 GHz 5.19 GHz 5.20 GHz 5.21 GHz 5.22 GHz 5.23 GHz 5.24 GHz 5.25 GHz 5.26 GHz 5.27 GHz 5.28 GHz 5.29 GHz 5.30 GHz 5.31 GHz 5.32 GHz 5.33 GHz 5.34 GHz 5.35 GHz 5.36 GHz 5.37 GHz 5.38 GHz 5.39 GHz 5.40 GHz N/A (not calibrated) N/A (not calibrated) N/A (not calibrated) N/A (not calibrated) TELEC FCC TELEC FCC TELEC FCC TELEC FCC N/A (not calibrated) FCC N/A (not calibrated) FCC N/A (not calibrated) FCC N/A (not calibrated) FCC N/A (not calibrated) N/A (not calibrated) N/A (not calibrated) N/A (not calibrated) N/A (not calibrated) N/A (not calibrated) N/A (not calibrated) N/A (not calibrated) Channel Number Channel Frequency Regulator Domain 82 84 86 5.41 GHz 5.42 GHz 5.43 GHz N/A (not calibrated) N/A (not calibrated) N/A (not calibrated) 5. To select the fixed data rate at which you want the station to transmit, double-click on rateCtrlEnable from the same registry key location where clist resides, and enter 0 to disable rate adaptation. Double-click on TransmitRate and enter the value specified in the following table to select the actual data rate. For example, enter 3 for 18 Mbps. Rate Number Data Rate 0 1 2 3 4 5 6 7 6 Mbps 9 Mbps 12 Mbps 18 Mbps 24 Mbps 36 Mbps 48 Mbps 54 Mbps 6. For the changes to take effect:
If you are running Windows 98SE or Windows Me, close Register Editor and restart the systems. If you are running Windows 2000 or Windows XP, unload and load the driver from LinkMon. 7. To undo these changes and go back to normal operation where the channel and data rate are dynamically set, change rateCtrlEnable to 1 and clear the clist value.
