It is not that uncommon to see your Xfinity router blinking green. Usually, this green light is closely connected to internet connectivity problems, so in order to fix the problem it is good to know what it actually means and how to fix it on your own.
So, let’s begin!
While in some cases the green blinking light doesn’t really indicates that there is a problem, Comcast and Xfinity users can experience an unstable internet connection.
Normally, there are several different reasons for that so let’s see what they are and how to fix them.
Loose or damaged cables
Normally, it is highly unlikely that you have any contact with the cables on your Xfinity router or modem. However, there are still chances that you have done something to them while cleaning the house, repositioning the router or modem or replacing the equipment.
So, just in case, check all the cables on both their ends and see if they are firmly connected o the appropriate ports. At the same time, check if there is any visible damage on the cables and connectors, and also whether any of the cables is bent unnaturally. Consider replacing the cable if you notice any damage.
If you have checked everything and the green light is still blinking after that, try the following step.
Your ISP can either have a scheduled maintenance going on, or there may be a power outage in your area that may result in you experiencing poor service quality or no service at all.
To check whether this is the reason for the green blinking light on your Xfinity router you can either contact Comcast directly, you can check the Xfinity app or visit a third-party site like downdetector.com to see what’s happening at the moment.
Damaged or malfunctioning splitter
Sometimes the reason for this problem can be the damaged or malfunctioning splitter. Normally, we highly recommend you to use the one provided by Xfinity.
To check whether the splitter is causing the problem, you can also connect the cable directly to the router and see what happens or you can try using another splitter if you have a spare one. Hopefully, you won’t see the blinking green light again.
To make sure your router is not overloaded, thus causing the green blinking light, it is recommended to disconnect some devices from the network and see what happens.
Additionally, you can restart the router and wee whether it will change something.
You can restart your Xfinity router either over the Xfinity app, Xfinity site or manually. The manual restart is what we highly recommend, and it is pretty simple. All you need to do is to disconnect the router from the power source, wait for about 60 seconds and then connect it back again. When the router boots up again the green blinking light should be gone.
Hard-Reset Your Xfinity Router
The factory reset is usually the last solution we recommend. This is because the router is being restored to the factory settings when you do this and it means that you will have to set up the router from the beginning.
Most people are uncomfortable with this so you can either do the hared reset or contact the Xfinity support to help you troubleshoot the problem.
You can properly reset the Xfinity router via the admin dashboard and the reset button on the router itself.
To factory reset the Xfinity router using the Admin dashboard, you need to login to your Xfinity router first. Then navigate to Troubleshooting in the left-hand menu, and select Reset/Restore gateway. Click on Restore Factory Settings.
This will reset the router to factory settings and you will be able to login to the dashboard again using the default username and password. However, you will have to set up the router from scratch now.

Another way to factory-reset the router is by using the hidden Reset button at the back of the router. Just take a paper clip or a pen and press and hold the Reset button for half a minute.
The lights on the router should turn off. Release the reset button now and wait for the router to boot up again. This should help you get rid of the green blinking light.
If you have tried all the steps given above and the green light is still blinking then it is time to get in touch with the Xfinity tech support. They can test and diagnose your connection and guide you through the necessary steps to fix the problem.
Hopefully, with their help your Internet connection will be up and running in no time and the Xfinity router blinking green issue will be fixed.

I hold a bachelor’s degree in network engineering and a master’s degree in computer science and engineering. I’m also a Cisco-certified service provider.
In my professional career, I worked for router/modem manufacturers and internet providers. I like to think that I’m good at explaining network-related issues in simple terms. That’s exactly what I’m doing on this website – I’m making simple and easy-to-follow guides on how to install, set up, and troubleshoot your networking hardware. I also review new network equipment – modems, gateways, switches, routers, extenders, mesh systems, cables, etc.
My goal is to help regular users with their everyday network issues, educate them, and make them less scared of their equipment. In my articles, you can find tips on what to look for when buying new networking hardware, and how to adjust your network settings to get the most out of your wi-fi.
Since my work is closely related to computers, servers, and other network equipment, I like to spend most of my spare time outdoors. When I want to blow off some steam, I like to ride my bike. I also love hiking and swimming. When I need to calm down and clear my mind, my go-to activity is fishing.
