Also, check that the wires are not damaged from anywhere as physical damage on the wire can weaken the connection. If you find that there is some kind of damage on the wire, then you must replace it with a new wire to stabilize the green light. 

2) Temporary outage

If regular maintenance or repair is going on in your area, then you will not be able to access the internet. When this happens, you will see a green light flashing on your router. If you find that the green light is blinking in an uneven pattern, then that means the signal is coming back. Once your ISP resumes the services, you are going to see a stable green light on your Xfinity router-modem. 

3) Hardware damage

Any damage caused to the hardware or splitters can lead to internet connectivity issues. The router needs to receive a signal from the wires in order to function properly. If any junction point through which the signal passes gets damaged, then it can lead to signal interruption. This can lead to a green blinking light problem on your router. To resolve this problem, you need to connect the router to the main cable wire. If the lights are solid green, then that means the splitter was the defaulter. 

4) Authentication failiure

To avoid overheating, keep your Xfinity modem router in a place where it receives sufficient airflow. 

6) Reset your Xfinity gateway
