4.3 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 2.5 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.
The configuration utility allows addition, modification, and deletion of the configuration profiles.
Select one of the existing configuration profiles under the configuration list to modify or click New
to add a new configuration profile. Follow Section 4.3.1 and Section 4.3.2 to set up the station to
work in infrastructure mode and ad hoc mode.
64
4.3.1 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. This name must be unique.
Configuration names are case insensitive.
Network Name (SSID): This is the name of the IEEE 802.11a Wireless LAN 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 802.11a turbo mode.
65
66
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. Typically, the appropriate encryption and decryption keys are
supplied by the corporate IT staff.
67
4.3.2 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 descriptions of ad hoc operation.
1. Similar to the setup of the AP infrastructure mode described in the previous section, ad hoc
mode is also configured by changing the Network Configuration Settings of the 802_11a NIC
Configuration utility. 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.
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.
2. You can optionally set up other properties, but 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. The system needs to reboot in order for the
changes to take effect.
68
4.3.3 TCP/IP Setup
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. 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. From "TCP/IP Properties," choose "IP Address" and
select "Specify an IP address." Input 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, and restart the system for the
changes to take effect.
69
2. Click "Start," "Programs," "Accessories," and "Command Prompt" to open the DOS 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.
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. To map the drive on another machine to your computer, right-click "My Computer" and click
"Map Network Drive...." 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.
