The simplest fix is to call your ISP since you are paying for the service. However, the problem may be something simple like a loose cable. Let’s explore a few common solutions:
1) Check the Physical Cables
First, ensure that your physical connections are secure. If you reset your router manually, a cable might have come loose. Check the router/ONT’s power connection cable and the Ethernet cable in the LAN port. If you have a Fiber Optic connection, examine the Fiber Optic cable from the Fiber Termination Box to the ONT. Routers nowadays have multiple LAN/Ethernet ports. Check all LAN ports one by one, after verifying that the cable itself is functional.
2) Power Cycle Your Router
Power cycling involves turning hardware off and then on again. A restart usually fixes most connection issues. If you have a router and modem combo, turn both devices off, wait for 30 seconds to 1 minute, and then turn them on again. The process is the same for an ONT. Unplug or turn your ONT off, wait for 30 seconds, and then turn it on again to complete the power cycle.
3) Internet Outage
If your ISP is experiencing an outage or conducting maintenance, you are likely to be informed beforehand. If not, contact them via their customer service helpline. Some ONTs indicate an Internet outage with a red light, meaning the router cannot connect to the Internet because there is an outage in your area.
4) Faulty Hardware
After checking your settings, router, and cables, consider if the Ethernet Controller on your motherboard might be at fault. Try using the same Ethernet cable with another device like a laptop. Most motherboards now come with built-in Wi-Fi. If Wi-Fi works flawlessly and the cable is not damaged, the issue might be with the Ethernet port or controller.
5) Check the Log Files
Your router’s web interface contains log files that can help diagnose the error if you can decode them. This option may be found under the “Maintenance” or “Diagnostics” section; consult your router’s manual for specifics. You can share these logs (while hiding sensitive information) on Reddit with experts for advice. Alternatively, reach out to your ISP; their technician will likely use the log files to diagnose the issue.
6) Reach Out to Your ISP
If you have exhausted all troubleshooting steps, contact your ISP. Remember, you are paying for both Internet and after-sales service. If the issue cannot be fixed remotely, a team from your ISP may visit to find the root cause of the problem. If your Internet is provided by a local ISP sharing bandwidth from a larger national ISP, your router is likely configured manually by the ISP during installation. If you reset your router, these settings are lost, and only the ISP can fix it.
