Troubleshooting

The PMG1005-T20C doesn't turn on.

• Ensure the power cable is securely connected and the power button has been pressed.
• Verify the power adapter is plugged into a working power outlet.

I cannot see or access the Login screen in the Web Configurator.

• Confirm your computer has an IP address within the same subnet as the PMG1005-T20C. For the default IP (192.168.1.1), your computer's IP should be between 192.168.1.2 and 192.168.1.254. Consult your computer's help for IP configuration.
• Double-check that you are using the correct IP address (default is 192.168.1.1).
• If the IP address was changed and forgotten, reset the device to factory defaults.
• Ensure your web browser does not block pop-up windows and has JavaScript enabled.
• Verify the User Name and Login Password are entered correctly. Use the default 'admin' and the password found on the device label.
• If you changed the password and cannot recall it, use a pin to press and hold the RESET button for more than 5 seconds to restore factory defaults, including the default admin password.

I cannot access the Internet.

• Check all hardware connections and the status of the LEDs.
• If the PON LED is off, restart the PMG1005-T20C.
• Inspect the fiber optic cable for loose connections or damage. Contact your vendor for replacement if necessary.
• Try disconnecting and reconnecting all cables to the PMG1005-T20C.

Note: If problems persist, please contact your vendor or customer support.
