Fixing this issue is rather simple so just follow the step described below. Since the broadband connection can’t be established for some reason we have to take a look at what may be causing this issue. So, let’s check the most effective solutions.

Check All The Cables And Connectors

When we say to check the cables and connectors there are actually several different things to do:

  • Check whether the cables are properly connected
  • Check whether they are firmly connected
  • Check whether the cables are damaged

Sometimes when we install new equipment by ourselves it is possible to connect a cable to the wrong port which will result in broadband connection problems. Therefore, when you are doing that we recommend you to place your old and new router side by side and disconnect and connect one cable after another. By doing this the chances to plug in the cable to the wrong port are minimal.

A loose cable can be a big problem because it is difficult to notice that without actually checking the connection. Therefore, we recommend checking the connectors on both ends of each cable and make sure that there are no loose connections.

A damaged cable or a connector can also cause the problem we are discussing in this article. Check your cables visually and if you notice any damage or some unnatural bending try to use a new cable and see whether the broadband green and red light are still blinking.

Restart the AT&T Router

This is one of the solutions that is as basic as possible but highly effective in resolving any issues you might have with your networking devices.

To restart your AT&T router manually you need to unplug it from the power source and after 15-20 seconds, plug it back again. Wait for the router to boot up and hopefully you will see a solid green light indicating that the router is connected to the broadband network.

Hard-Reset the AT&T Router

If the tips given above haven’t helped you fix the broadband light blinking green and red problem, then it is recommended to hard-reset the router. This practically means that the router will be reset to factory settings. You need to know that this means that every change in the settings you have made before will be erased. This applies to the static IP address, port forwarding, custom network name and wireless password. When you hard-reset the router you will be able to connect to the network with the default Wi-Fi password and login to your AT&T router using the default admin username and password.

If you decide to hard-reset your AT&T router follow these steps:

  1. Find the Reset button at the back of the router.
  2. Depending on the router model, press it with a paper clip or something similar or just press the Reset button with your finger, and hold it like that for 10 or more seconds.
  3. After this time the router will restart. When it boots up again and all the LED lights on the router become stable again, the green and red blinking light should be history. Instead you should see a solid green light.
