An unstable internet connection or complete outage can be very frustrating, especially as most devices we use need a working connection to function properly.

If you experience internet connection issues, the first thing we do is check the router’s lights. In most cases we will see the AT&T broadband red light.

So, the question now is what does it mean and how you can fix the AT&T broadband light red?

What does the AT&T broadband red light mean?

When the AT&T broadband light is red it is good to know what are the possible reasons for it.

They are as follows in this instance:

  1. The gateway isn’t working correctly
  2. It is impossible to detect DSL or broadband signals.
  3. The gateway can’t connect to the service provider network

Now when we know the possible reasons let’s see what we can do about it.

How to fix the AT&T broadband red light?

These fixes are simple enough that you can use them all.

Look out for service outages

AT&T has an outage site located at this address where you can check if there is a service outage in your area at the moment. These happen after a power cut or storm. If this is the cause of your red light problem, you will need to wait until things are back up and running.

Make sure to inspect the connections, particularly the DSL Broadband green cable

Sometimes, a loose connection could be the problem. You can check your connections easily, or disconnect everything and reconnect everything again. This will ensure that everything is tight and secure. Make sure the DSL Broadband green cable is securely inserted into the gateway.

Start the gateway manually

You don’t need any special tech skills for this one but restarting a device usually resolves most of the problems you may experience. If the problem persists, you will need to restart your modem.

Reset the modem back to factory defaults

This option is usually left at the end. This is because your modem will be reset to factory settings. You will need to setup it again. All customizations, including network name, Wi Fi password, guest network, and other settings, will be lost.

You can still proceed if you wish. Here are some official solutions on how to factory reset your AT&T modem.
