Steps To Fix AT&T Broadband Blinking Red Light Issue

Here are some of the troubleshooting methods which will help you to fix the AT&T broadband blinking red light.

Check all the cords and connections

The first thing you need to do is check all the cords and connections. Make sure that everything is plugged in firmly and there are no loose connections. Once you’ve done that, restart your Att gateway and see if that solves the problem. Follow the below steps if you don’t know how to restart your modem or router:

  1. Just unplug the cord from the wall adapter
  2. Wait for a couple of minutes
  3. Plug the cord back in and turn on the device.
  4. Wait until all the LED lights stop blinking.

If your broadband is still showing red light that means you need to move to the next solution.

Check for outages in your area

Sometimes, the problem isn’t with your equipment but with the service itself. There might be an outage in your area that’s causing the issue. You can check for outages on AT&T’s website or by calling customer service.

Outage means that your particular area is being affected by some technical problem so all you can do is wait until the problem is fixed.

Update Gateway Firmware

You might be able to prevent this from happening by making sure that your network devices are up-to-date with all of the latest software. You can also try reseating any cables or rebooting them as well!

If none of these solutions work then it’s probably time for you to fix some bugs to avoid interruptions while online browsing.

Luckily fixing these problems isn’t difficult at all! You’ll only need to spend five minutes on this task and then you’ll be good as new again – so don’t stress out too much about what might have gone wrong if something does go wrong because we’ve got everything taken care of here for YOU!!

  1. From a PC or a mobile browser, go to Smart Home Manager and sign in.
  2. Select Home Network Hardware.
  3. Choose your Wi-Fi Gateway > Device Details.
  4. Now you can see the firmware version.

If your router or modem’s firmware version turns out to be old then update it by the following methods:

  1. Go to Smart Home Manager.
  2. Choose Network > Home Network Hardware.
  3. Choose your Wi-Fi Gateway, then select Restart.
  4. Confirm the Restart.

Now check again to make sure your version has been changed.

Reset Gateway or Router

If your problem still persists then the only solution left is to reset your router or modem. By doing this, all of your settings will go back to default which might fix the problem. Although, you’ll have to set up your equipment again from scratch.

To reset your router:

Hard Reset: Press and hold the Reset button on the back of the gateway for about 10 seconds.

Soft Reset: Unplug the power cord from the gateway, wait about 15 seconds, then plug it back in.

After that, check to see if your problem has been fixed or not!

What lights should be on my AT&T router?

The answer to this question depends on which AT&T router you have. Most routers have a power light, a Wi-Fi light, and an Ethernet light. The power light should be green and the Wi-Fi and Ethernet lights should be white. If any of these lights are not lit, it could indicate a problem with your router.
