3. 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.

 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. 2.5.1 Infrastructure Mode To configure an 802.11a Wireless LAN 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.

2.5.2 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.

2.5.3 TCP/IP Setup After configuring the 802.11a Wireless LAN Network Adapter through the Network Control Panel, the TCP/IP address for the network device must be configured. 1. 2. 3. Open the "Control Panel" and click "Network and Dial-up Connections." Find the "Local Area Connection" that is associated with the 802.11a Wireless LAN Network Adapter. Right-click that connection, and click Properties. Select "Internet Protocol (TCP/IP)" and click Properties. 4.

6. Click Start, Programs, Accessories, and Command Prompt to open the DOS command prompt window. Type "ipconfig" at the C:\> prompt to determine if the TCP/IP configuration has taken effect. To test IP connectivity in ad hoc or infrastructure mode, use the "ping " command. When a TCP/IP connection is established, the LinkMon utility (See Section 6) can be used to monitor the 802.11a Wireless LAN Network Adapter operating status.

3 Windows Millennium Edition 3.1 Driver Installation We recommends that you remove any existing 802.11a NDIS driver on the PC system before installing Version 1.2 release of the NDIS driver. See Section 3.2 for the instructions on how to remove previous driver releases. When the system no longer has the 802.11a NDIS driver installed, insert the Wireless LAN Network Adapter into a 32-bit CardBus slot, and follow these steps to install the NDIS driver: 1. Wait for the following dialog box to appear.
PAGE 10
2. Choose "Search for the best driver for your device. (Recommended)" and select "Specify a location." Click Browse to locate the NDIS driver. The default folder is "D:\ndis\bin\production) (assuming D: is the CD-ROM drive). Click Next to continue.
PAGE 11
3. When the 802.11a driver installation file (NET5210B.INF) has been found, click Next to continue. 4. Click Finish to continue, and restart the system to complete driver installation. Refer to Section 3.3 for device configuration.
PAGE 12
3.2 Driver Uninstallation This section provides uninstallation procedures for removing the 802.11a NDIS driver from the system. Uninstallation is recommended for upgrading the NDIS driver from previous 802.11a driver releases. 1. To remove the NDIS driver from the OS, go to "Start Menu" "Search" "Find Files or Folders...," and search for the INF file containing the "802_11a" text string under the \WINDOWS\INF folder. Be sure to include subfolders in the search criteria. When "802_11a.

3.3 Device Configuration Configuration of the 802.11a Wireless LAN Network Adapter can be done through the 802.11a NIC Configuration utility found in the Windows Control Panel. Similar to Windows 2000 the device can be set to work in one of two modes: infrastructure mode or ad hoc mode. Please refer to Section 2.4 for more details on these network connection types. To launch the configuration utility, go to Control Panel and double-click on the 802.11a NIC Configuration icon.

3.3.1 Infrastructure Mode This section defines the process of configuring an 802.11a Wireless LAN Network Adapter in infrastructure mode. See Section 2.4 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.

2. 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 802.11a Wireless LAN Network Adapter and NDIS driver support key lengths of 40 bits, 104 bits and 128 bits.
PAGE 18
3.3.2 Ad Hoc Mode This section defines the process of configuring an 802.11a Wireless LAN Network Adapter in ad hoc or IBSS mode See Section 2.4.2 for description 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 the Network Configuration Settings of the 802.11a NIC Configuration utility.
PAGE 19
2. You can optionally set up other properties, bur 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 802.11a software implementations will provide unique key support. 3. Click OK when the properties are set correctly.

3.3.3 TCP/IP Configuration After configuring the 802.11a Wireless LAN Network Adapter network adapter properties, the TCP/IP address for the network device needs to be configured. 1. From Control Panel, launch the Network properties window. Select “TCP/IP → 802.11a Wireless LAN Network Adapter" and click Properties. Depending on the type of network the station connects to, Gateway and DNS Configuration information can also be required.
