# Test the Adapter from Microsoft Windows*

Intel® PROSet allows you to run several diagnostic tests, including:

- Connection Test: Tests the adapter's connection to the network. If the adapter connects below its maximum speed, the connection test reports the reason for this lower speed. If the adapter has link but does not have an IP address, the test reports whether the adapter can communicate with the link partner. If the adapter has link and has an IP address, ping tests are performed.

- Link Test: Tests the link speed and duplex capabilities of the link partner and reports the optimum settings.

- Cable Tests: Provide information about cable properties.

- Hardware Tests: Determines if the adapter is functioning properly.

To access these tests, select the adapter in Windows* Device Manager, click the Link Speed tab, and click Diagnostics. A Diagnostics window displays tabs for each type of test. Click the tab and run the test.

The availability of these tests is dependent on the adapter and operating system.
