Everything is hooked up but nothing is working. What should I do?

When you troubleshoot issues with a VDSL Extender, there are some quick tests that you can complete to rule out potential problems. To identify what the source of the issue is, observe the power LED, LAN LED, and VDSL LED on the units.

If the power LED is not illuminated for the transmitter or the receiver, complete the following:

  • Make sure that you are using the provided power adapter(s).
  • Make sure that the adapter is plugged into a compatible wall outlet.
  • Make sure that the adapter is plugged into both the transmitter and receiver.

If another LED is not operating as expected, make sure that the components in your setup are working correctly. To test your setup components, try the following:

  • Use the cables, VDSL extender, and network devices in another setup to see if the problem is with the components or the setup.
  • Use different cables, a different VDSL extender, and network devices in your setup to see if the problem persists. Ideally, you should test components that you know work in another setup.

When you test your cables, it is recommended that you do the following:

  • Test each cable individually.
  • Use short cables when you are testing.

Make sure that the DIP switches are set to the following:

  • DIP switch one (CO/CPE) is opposite on both units. It does not matter which unit is set to CO or CPE.
  • DIP switches two to four are identical on both local and remote units. By default, DIP switches two to four are set to Off (the switch is pointing up).

If there is still no VDSL connection or if there is intermittent connection issues, try the following:

  • Modify the Signal to Noise Ratio (SNR) by changing switch four on both units.
  • Modify the operation mode of the unit by changing switch two or three so that they match on both units.

If you cannot establish a network connection between your remote and local units, you need to do the following to make sure that the issue is not related to the network configuration:

  • Use two computer systems directly connected to the VDSL extender LAN ports.
  • Open a command prompt on Computer 1 and ping Computer 2.

If the issue is not related to the network configuration, you should receive a response from Computer 2.
