Diagnostics – Troubleshooting
The Diagnostics – Troubleshooting page contains a number of predefined tests with test results and other diagnostic settings.
Connection tests
This group contains the results of fourteen tests of various aspects of your connection to
your local network, the connection to your DSL service provider, and the connection to
your Internet service provider.
Note – Your Internet service provider must support diagnostics features in order for correct
DSL diagnostics results.
Diagnose the connection by clicking the Test button or click the Test With OAM F4
button.
The following results indicator buttons will display for each test:
A Pass icon displays when the connection is operating
correctly.
Click Help to see the criteria for success for this test.
A Fail icon indicates that the test was unsuccessful.
Click Help to see the possible reasons for the failure.
In the Help screen there are also Troubleshooting suggestions
specific to that particular type of test which may be able to
rectify the problem.
Click the Rerun Diagnostic Tests button after the
troubleshooting has been completed.
The service is either disabled by a setting in your NF18ACV or
that diagnostic functionality is not supported by your ISP.
If after trying all the troubleshooting suggestions you are still experiencing a fail condition, contact your ISP Technical Support.
