When a connection issue is detected, a desktop alert appears at the bottom right corner of your desktop screen. Once you click on the desktop alert, a diagnostic message displays the steps recommended to resolve the connection issue. For example, if a connection issue occurred because of an invalid password, the Profile Wizard application is launched when you click on a displayed hyperlink. You can also launch Wireless Event Viewer and enable or disable alert notifications. The Intel Wireless Troubleshooter is supported under Microsoft Windows XP and Microsoft Windows 2000.
