However, a modem is a lot more complex when it comes to the details. There are many aspects that need to be taken care of. If even one thing does not work the way it is supposed to, then the modem will not get you connected to the internet.

There are many ways that the modem signals that there is some problem with the modem. One of these ways is by blinking in different colors. 

In this article, we are going to address the question of How to Fix AT&T Modem Broadband Light Blinking Red and Green.

We will first discuss what it means when the modem blinks in these specific colors, why it might be happening and how it can be solved.


What does it mean when the AT&T modem blinks red & green?


When you see that the AT&T Modem is blinking in red and green color, it shows that the modem has been trying to establish an internet connection for more than 3 minutes.

When the modem is unable to connect even after three minutes have passed, it shows the inability to connect to the internet by blinking in red and green colors.

So, now we know that the exact issue is the modem not being able to connect to the internet.


Why “AT&T Modem Broadband Light Blinking Red & Green”?


Now let us discuss, what are the factors that are causing the modem to fail in connecting to the internet.

Reason 1: The network is weak

It is quite possible that the modem is facing issues in connecting to the internet because the internet service provider is facing server issues.

This will cause serious network trouble and with no fault of the modem, will cause the connection to fail.


Reason 2: The cables to the modem are loose or worn out

The cables that connect to the modem are very important to the functioning of the modem. If the cables are not connected securely, then the modem will not be able to function.

The cables could also be old and worn out and that is why the cables may break.


Reason 3: The modem is not recognizing the networks due to a bug

There are many bugs that may cause a modem to face issues with the internet connection. In these cases, the internal issues with the modem need to be solved before the internet can be connected again.

The modem might also be out of essential updates or the modem model might be old. All these issues need to be addressed before the internet connectivity.


Reason 4: Hardware issues with the modem

As discussed above, if the model of the modem is old then the device might be out of commission. In these cases, there might be several hardware issues that will take over and not let the modem connect to the internet.

Sometimes, due to the issue in the hardware, you will also see the modem blinking without any errors in the internet connection.

You might wonder what is wrong as the internet is working fine, but in such cases, it is merely a hardware issue.
