Causes of Xfinity Modem Blinking Green

This is usually due to a lack of enough airflow or the placement of your router in an area where a lot of heat is generated.

Cables are Broken

Another cause of the Xfinity router’s blinking green light is the use of loose cable connections, which interfere with the internet connection. 

This type is only extremely sensitive, necessitating frequent examinations. If we do not do so, it will begin to lose on its own after a period of time.

Alternatively, we can put them in a location where there are a lot of people coming and going. Then they break it somewhere, and you start having problems with loose cable connections.

Power Interruption

When your Xfinity modem or router isn’t getting enough power, you’ll notice an internet connection problem. After that, you’re stumped as to how to solve it.

This power loss is similar to a local power outage, in that it affects both your home and your business.

This power outage is a form of a server problem that causes issues since the signal speed is not received properly.

Failure to Communicate with the Router

Because you are using multiple modems, you are having trouble communicating with one another. 

A blinking green Xfinity router can result from miscommunication, causing your internet connection to become slow or even unusable. This kind of fluctuation wreaks havoc on the internet’s stability.

Authentication with your ISP Failed

Everyone understands that the modem is connected to a specific type of internet, but when it fails to detect your connection, we call it authentication failed. After that, the only way to solve the problem is to contact the Internet service provider. 

By the way, this issue is usually caused solely by the ISP. You do not need to be concerned that are simply waiting for a little, or alternatively contact your ISP.
