How to Fix the AT&T Broadband Red Light Flashing

Move Your Router

The router may not be receiving a good signal if it’s placed in a dead spot location.

When this occurs, your network will detect the weak signal and alert you by blinking the red light.

Hence, moving the router to a location with less interference might help with this issue. Usually, it’s a good idea to put it somewhere high.

Check for Loose Connections

A loose connection may affect how the router receives the signal.

That said, check the cable for connection and ensure that they’re firmly attached to the router. If cables are damaged, you’ll have to replace them with a new ones.

A red light blinking may also indicate that a cable is bent or pressed firmly up against a sharp object. 

Power Cycle Your Gateway or Modem

Power cycling your gateway or modem to refresh the connection.

You’d be surprised at how often a quick power cycle will solve most issues with electronic equipment, even your AT&T broadband.

Follow these steps to power cycle your AT&T router:

1. Shut down your modem or gateway.
2. Disconnect the device’s power source.
3. Shut down the device for 60 seconds (at least)
4. Reconnect to the power supply.
5. Turn the device on.

Update Software

If your gateway hasn’t had an update in a while, buggy software may be a cause of this issue. In such cases, the gateway suddenly stops being able to connect to the internet.

If you decided to do this, you must first check your firmware version by following these steps:

1. Log in to Smart Home Manager on your phone or computer.
2. Choose home network hardware.
3. Choose Device Details, then your Wi-Fi Gateway.
4. The firmware version can be seen at the bottom of the page that opens.

After finding out the firmware version, you’ll also see some available updates. If there are, here’s how to update the AT&tT firmware:

1. Open your device’s web browser.
2. Open Smart Home Manager and log in.
3. Select Network.
4. Scroll down to locate Home Network Hardware.
5. Choose Restart after selecting your Wi-Fi Gateway.
6. Restart!

After the upgrade, the red light on the broadband should turn off.

Call AT&T

If nothing seems to work, you can call AT&T for help.

Additionally, AT&T should be able to inform you if there is an outage in your area (even if it doesn’t appear on the map) or if there might be a problem with your router or modem resulting in that red blinking light on the modem.

Conclusion

The red light blinking on your AT&T router usually means that there is no internet connection. It can be a problem with the AC power cord, connector or your gateway may require an upgrade.

The quickest solution is to restart the modem and check for firmware updates. You can also call AT&T to help you resolve the issue after attempting some basic troubleshooting.
