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.
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.
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.
− 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.
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.
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.
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.
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.
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.
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.
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.

7 LinkMon Installation 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.
3. Click Next to continue. 4. Click “I accept this agreement” and then click Next to continue.
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.
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 Transmit Retries tab is detailed transmit retry statistical information for transmitted frames.
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.
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….
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.
