8. Windows NT 4.0 binds TCP/IP protocol to 802.11a Wireless LAN 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 1P address.
9. Restart the system for the changes to take effect. 6.2 Device Configuration Configuration of the 802.11a Wireless LAN Network Adapter can be done through the 802.11a NIC Configuration Control Panel applet . 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 2.4 for more details on these network connection types. Start 802.11a NIC Configuration utility form the Control Panel.
Select one of the configuration(s) under the configuration list and click Modify or click New and follow the Section 6.2.1 and Section 6.2.2 to set up the station to work in infrastructure mode and ad hoc mode. 6.2.1 Infrastructure Mode This section defines the process of configuring an 802.11a Wireless LAN Network Adapter in infrastructure mode. Refer to Section 2.4 for detailed descriptions of each option in the Network Configuration Settings. 1.
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 802.11a Turbo mode.
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.
6.2.2 Ad Hoc Mode This section defines the process of configuring an 802.11a Wireless LAN Network Adapter in ad hoc or IBSS mode.

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 802.11a software implementations will provide unique key support. 3. In ad hoc mode, a station will scan the air for an existing Basic Service Set (BSS). If no BSS is found, the station will establish a BSS for other stations to join.
6.2.3 Verify Connection You may use LinkMon utility to monitor the operating status of 802.11a Wireless LAN Network Adapter once the STA is connected. Please refer to Chapter 7 for descriptions of LinkMon utility.
