First, check the fiber optic cable connection at the ONT device. The cable should click firmly into place and the green light should stay solid, not blinking. If you see red or no light at all, unplug the ONT power adapter for 30 seconds, then reconnect. Sometimes dust accumulates in the fiber connector, so gently clean it with a lint-free cloth if you need to reseat the cable. Check your router's WAN port connection as well. Many connection drops happen because the ethernet cable between ONT and router works loose over time.
Connect your computer directly to the router with an ethernet cable and run a speed test. WiFi almost never delivers the full fiber speed, especially through walls or on older devices. If the wired speed is still low, restart your router and the ONT device. Wait three minutes between restarts. Check if other household members are streaming 4K video or downloading large files simultaneously. Your router's Quality of Service settings might also be throttling certain types of traffic.
The ONT device needs about two minutes after power-up to authenticate with the network. If the internet light stays red after five minutes, there might be a service interruption in your area. Check the service status page on your smartphone using mobile data. Verify that your account payment went through, as automatic renewal failures can temporarily suspend service. If everything checks out, note down all the LED statuses on both devices and contact technical support with this information.
This usually points to upstream bandwidth congestion. Log into your router settings and check how many devices are connected. Smart home gadgets, security cameras, and automatic cloud backups consume upstream bandwidth quietly in the background. Disable or schedule these for off-hours. Position your router centrally and away from microwave ovens or cordless phones. If you're on WiFi, switch to the 5GHz band for video calls since it handles real-time data better than 2.4GHz.
