If the distance between the Access Point and the
system is too far, the test may report failure even if
the device is properly working. If the encryption is
enabled on the Access Point, the test program
cannot properly communicate with the Access Point
to test the device, and will report failure.
Due to the nature of wireless connection, the test
may report failure with "No LinkTest response
received" error message in the log, even if the
device is working properly. When the test failed with
this error, please repeat the test for a few times.
The device may be working properly unless the
same error persists.

Keyboard Test. See "Running the Diagnostics" on page 27
for details.
