It also offers some more configuration options. The Adapter offers the Configuration and Monitor Application for Windows 98, Windows 2000 and Windows ME. Note: Please keep in mind that the Configuration and Monitor Application can be used to change the above configuration parameters when the Adapter is active. When the Adapter is not in use, please use the Control Panel method described in previous sections. 6.1 How to Install the Configuration and Monitor Application In order to setup the Configuration and Monitor Application, run the program SETUP.EXE, which you will find in the Config_Utility folder of your installation CD and follow the instructions as they appear on the screen. As soon as a link is established, the application will start running and will appear as an icon on the system tray. You can locate the application under Start -> Programs -> Instant Wireless - Network -> Instant Wireless - Network USB Adapter Configuration. 6.2 Using the Configuration and Monitor Application The Configuration and Monitor Application appears as an icon on the system tray of Windows every time the Adapter is running. You can open it by doubleclicking on this icon. While the station is in infrastructure mode and not associated to an access point, the color of the icon is red. As soon as the station associates itself to an access point, the icon color turns to blue. In ad-hoc mode the color is always blue, except when the card is reseting where it turns to red during the reset procedure. A typical screen of the application in infrastructure mode is shown in Figure 6-1. The configuration parameters are shown at the top of the screen, while the statistics of the communication are shown at the bottom. In the middle of the screen there is information about which Access Point the Adapter is associated with, the address of the AP, its SSID and the channel. The four LEDs at the 24 Instant Wireless - Network USB Adapter User Manual bottom of the dialog box indicate which of these features are enabled. Figure 6-1. A typical screen of the Configuration and Monitor Application in infrastructure mode. A similar screen appears in case the Adapter operates in ad hoc. In this case, Short Preamble has been enabled (Figure 6-2). 25 Instant Wireless - Network USB Adapter User Manual Figure 6-2. A typical screen of the Configuration and Monitor Application in ad-hoc mode. By pressing the Change button in any of the two modes, you can change basic configuration settings such as the Operating Mode, Channel, SSID, and Transmission Rate (Figure 6-3). While in infrastructure mode you can select a preferred Access Point (AP) by checking the Enable check box and giving the MAC address of the AP. In that case you must also specify the channel the preferred AP is using. 26 Instant Wireless - Network USB Adapter User Manual Figure 6-3. Change of basic configuration. By pressing the Advanced button in any of the two modes, you can change advanced configuration settings, such as the Preamble Type, Fragmentation Threshold, and RTS/CTS Threshold (Figure 6-4).
