Step 1: Check for Service Outages
Before diving into more complex troubleshooting, check if there is a service outage in your area.

If an outage is reported, there’s nothing you can do but wait until the service is restored. You can also sign up for outage notifications to stay updated.

Step 2: Inspect All Cables and Connections
Check all the connections that link your modem to your wall outlet, router, and other devices. Loose or damaged cables are often the cause of connectivity issues. Disconnect and reconnect each cable to ensure a secure connection. Inspect the coaxial cable and Ethernet cable for visible damage. If you find any frays, cuts, or other damage, replace the cables to ensure proper functionality.

Ensure that your modem is not overheating by placing it in a well-ventilated area. Remove any objects around the modem that may be blocking airflow, and avoid placing the modem near heat-producing devices like a television or a gaming console.
If your modem has been overheating, turn it off and allow it to cool down. Once it’s cool, power it back on and check if the red light persists.
Step 5: Update Modem Firmware
Outdated firmware can also cause issues with connectivity and lead to a red light on your modem. Check if your Cox modem’s firmware is up-to-date. If your modem has a built-in system for automatic updates, it should have updated itself. However, if updates are available, follow the instructions provided by Cox to manually update the firmware.
