The Diagnostics menu provides a suite of tests which you can
run to identify problems with your computer�s connection to your adapter and to
the wireless network. Clicking this tab displays the following window:

The MAC and IP addresses used by your adapter appear at the
top of this window. The window below these addresses lists the tests you can
perform. Choose the test or tests to perform by clicking the check box next to
the desired test(s). You can select all tests by clicking the Select All
button, or clear all check boxes by clicking
the Deselect All button.
When the tests you wish to run are selected, click the Run button.
The Configuration Utility then performs all
the tests you have selected and displays the result of the test in the window.
You can stop all tests in progress by clicking the Stop
button.
At the bottom of the Diagnostics menu are three buttons. Clicking the
OK button applies any changes you made in this or any of the other menus
of the Configuration Utility and closes the utility. Clicking the Cancel
button cancels any changes you made since you last clicked the Apply but
does not close the utility. Clicking the Apply button saves any changes
you made in this or any of the other menus of the utility and leaves the utility
open.
