If you’re still experiencing a blinking green light on your Xfinity modem, it’s crucial to check for local outages. Local outages, whether due to maintenance or unforeseen issues, can impact your internet connection. To determine if there’s a local outage affecting your service, visit the official Xfinity status page or contact Xfinity support. This step ensures that you rule out external factors contributing to the blinking green light and allows you to stay informed about any ongoing service disruptions in your area.
4. Disconnect And Reconnect All Devices
When you find a blinking green light on your Xfinity modem, disconnecting and then reconnecting all devices connected to the modem can help troubleshoot the issue.

5. Clean Your Xfinity Modem Or Router Ports
Did you know that a dirty router or modem can interrupt your internet signal and cause your modem to blink green? Yes, it is. If you didn’t clean your modem or router devices properly and regularly, then it’s time to perform a proper cleaning section.
Leaving the devices untouched at any location for a long time means providing a clear way for the dust and debris to get inside the ports and might restrict the cable connection. So, clear the debris carefully from the ports of your devices by using a dry, soft brush, and make it a routine.
6. Make A Direct Connection
To address the blinking green light on your Xfinity modem, consider connecting the modem directly to the main cable, bypassing the use of a splitter. A splitter is a coaxial cable device designed to divide a single incoming cable/internet signal into multiple outputs/devices. If the splitter is malfunctioning or broken, it can disrupt the connection and result in the blinking green light. By directly connecting the modem to the main cable, you eliminate the potential issues associated with a faulty splitter, providing a more direct and stable connection for your Xfinity modem.
7. Disconnect Some Devices From The Xfinity Modem/Router
When troubleshooting a blinking green light on your Xfinity modem, consider disconnecting some unused or heavy bandwidth-consuming devices from the network to alleviate potential overload or congestion issues. Here are the steps to disconnect devices:
