First, ensure your ONT (Optical Network Terminal) has a solid green Power and PON light. If either light isn’t solid green, check the power supply connection and the fiber cable connected to the ONT's PON port. Make sure the cable is securely connected to the ONT, and follow the cable line through your house, checking for any visible issues like cuts or kinks, especially if it runs underground or overhead. If you find any problems, call us 24/7 at 1-800-282-5064, option 2.
Additionally, the ONT should have a flashing Data light, either amber or green. If the Data light isn’t flashing, but the Power and PON lights are solid, there might be an issue with the LAN cable between the ONT and the router. Ensure the ethernet cables are securely connected at both ends and inspect them for any damage. If the issue persists, try replacing the ethernet cable.
