Check the AT&T network

For fast internet connectivity, all the hardware must function optimally. This means that you should check for any loose connections or damages. Ensure that the wires are properly plugged into the right ports. Replug or tighten all the connections on your router and modem.

Also, make sure that the main power source is undamaged and is working properly.

You can also try to move the router to some other place for better internet connectivity.

Power cycle the Gateway

To power cycle, shut down your device and then remove all the connections. Wait for a few minutes and then put back all the connections and turn on the device.

Power cycling fixes any minor bugs that can affect the device and hampers the internet connectivity.

Update the firmware

Companies release regular firmware for their device to patch any malfunction or errors. So, it would be a good idea to update the firmware when it is released.

You can use the AT&T app to update the gateway. If updating the gateway doesn’t fix the problem, then move on to the other steps.

Reset the Gateway

To perform a factory reset, press and hold the reset button for 15 seconds. The device will reset automatically and the light will turn green from red.

You should perform a factory reset only as a last resort as it will remove all the data.

Contact AT&T support

If all else fails, then contacting AT&T support is the last option. Head on to the AT&T support page and then type in your issue. You can also call support at the number given on the support page.

We hope that this guide will help in fixing the AT&T broadband red light issue.
