Causes Behind Xfinity Modem Blinking Green

The Xfinity blinking green light indicates an unstable and faulty internet connection. However, if the Xfinity modem is showing a stable green light, then it indicates a steady internet connection. Even though it is a modem or a modem router combo. 

A blinking green light indicates the internet is malfunctioning. There can be a number of possibilities; for instance, the modem was kept on rest, or the cables are loosely plugged. Below we have listed the causes:

  • The broken ethernet cables. 
  • The provider’s end is the main culprit.
  • The power outage.
  • Network overload.
  • The hardware is having issues.
  • The gateway configuration is wrong.
  • Due to overheating.
  • Due to overwhelmed splitters.
  • These issues are quite common. 

Now, let’s take some time to address these issues.

What are the Ways to Fix the Xfinity Modem Blinking Green?

You should not take too much pressure on yourself when you observe the Xfinity modem blinking green. It is quite a common problem, and we have also given the appropriate focus on its fices. Thus, you won’t face any problems. Below we have discussed the fixes:

1. Proper Cables

Cables are one of the key reasons for a steady internet connection. Henceforth, it is very important to have a proper cable. Make sure to check the cables, if they are rightly connected or not. Also, it is very important to know whether any further damage has been caused or not. 

Unplug the cable and again plug in to see whether it’s making any difference or not. If you observe that the cables are cracked or broken, replace them as soon as possible. It is also important to check the splitter connection and health. 

2. Maintenance 

Maintaining equipment and cables are also very important. ISP even shut down the internet services to maintain equipment and cables. Henceforth, this can be the reason why you are experiencing an unstable internet connection. Thus, at the end of ISP, the internet outage can be the reason for the Xfinity modem blinking green.

When any users log into the  Xfinity account, they get notified about the maintenance sessions and outages. You will also get an advanced message from the service provider in advance. We also advised you to keep track of every update to stay away from issues like this. 

3. Power Cycle the Modem

After you check the cables, now is the time to power cycle the modem if the former one does not work. You can either unplug the router from the power supply or remove the power cord from the router. 

Make sure you keep it unplugged for at least 15-25 seconds. After you have unplugged, press and hold the power button on the modem and plug the router back in. Finally, see if this step helps you out or not. 

4. Make a Direct Connection

You can use the main cable to plug directly into the router. This means that you don’t have to use the splitter to divide and separate the connection. In case you don’t know how to distribute the bandwidth to different devices a splitter is used. In the case of the splitter brakes, you might observe the blinking green light. 

5. Modem Overloading 

Network overloading arises when you enroll for a high-speed internet plan, and thus can be one of the causes for the green light blinking. There is a possibility that the networking device is connected to several other devices at once, thus limiting the services. And, you might experience a drop in internet connection. 

6. Factory Reset

You can also use the factory reset to solve the problem. Plugged in the modem if you see it is not and observe the power LED light has been enabled. At the back of the router, you will notice a small hole. 

You will see the Reset written either below or beside. Hold the reset button for at least 6 seconds. Further, you don’t need to press when the lights are off and when the Power light is turned back on again. 

7. Check for Service Interruption

You can also check the Xfinity website and observe if there is any service interruption or outage in your region. You can also check it through your XFI application. 

  • First, you have to launch the XFI application.
  • Now, log in using your account and locate the Check The Link Of Service Interruption. 
  • Finally, you need to check if the problem is solved or not.
