In certain instances, there’s nothing you can do about the ATT gateway broadband light blinking green; you have to wait it out or contact customer service. Here are a few troubleshooting tactics to assist you: 

1. Restart the AT&T Router

The number one solution to blinking broadband 1 light AT&T is to restart the modem. When you take this action, you’re clearing the cache for the internal memory. Therefore, whichever configurations or glitches were causing an issue will usually get wiped clean once the rebooting process starts. 

Follow these steps to restart your modem and correct an ATT broadband light blinking green:

  1. First, unplug the router cord from the power source. 
  2. Allow it to stay like that for about 30 seconds, and then plug it in again. 
  3. Next, turn the device’s power on and let it reboot entirely. 
  4. Finally, see if there’s still a blinking green broadband light ATT.

If this hasn’t fixed the problem, try the following options. 

2. Check for Service Outage

You always want to ensure that you check for maintenance or any service outages announced by the company. If the broadband signal isn’t strong enough, it results in you seeing the broadband light green but flashing or an ATT broadband light red. 

Head to the information page online that displays service outages in your area. Login to your personal account details, or use your zip code to confirm if others are likely having problems. 

This problem is a situation where you’ll need to have patience until the technicians resolve the connectivity issues.

3. Use the Smart Home Manager App or the Troubleshoot & Resolve Page 

You can also check out the Smart Home Manager app to attempt to find the problem behind your bgw320 blinking green light. You might also come across extra tips not listed that can help you fix the issues efficiently. 

Aside from the Smart Home Manager app, the Troubleshoot & Resolve page has specific areas with inquiries regarding blinking lights and how to address them. 

Once you sign into your account through the app, you can select the diagnostics option and wait to see the recommendations presented to you. 

4. Check To See That The Connection is Stable

After trying everything under the moon for an ATT broadband light blinking green, it all comes back to the connection strength. Sometimes users report that everything is working fine, and the connection starts getting shaky, and the light blinks. 

In this case, you can disconnect just the connection cable and plug it in again after about 20 seconds. If your connection doesn’t seem stable despite this effort, proceed to the next option. 

5. Reset Your Modem or Gateway

The only drawback is that your custom settings will get erased, so you must customize your settings again. 

However, if you make your wireless password and network name the same as they were before, you won’t have to reconnect all of your home devices to the network again. 

On the contrary, if you change your password and network name, you’ll have no choice but to reconnect your devices to your new network name and use your new password to gain access.

Below are the steps to reset the AT&T router correctly:

  • Find and press the reset on the back of the router—hold it for ten seconds.
  • After ten seconds pass, the router will reboot—release the button.
  • Wait a few moments, and it’ll start rebooting.
  • At this point, the blinking green light should remain solid now.

6. Disconnect and Reconnect Your Modem or Gateway

If the standard reset fails to remedy the problem, try to unplug the Gateway or modem, wait 45 seconds, then reconnect the plug.

Next, wait for the modem to reboot, ensuring all the lights turn solid green without blinking, as you may see the ATT router blinking red first.

7. Check the Cables Plugged Into Your Modem or Gateway

A damaged or loose cable can cause the broadband light to blink. Therefore, check all the wires in your home network if the problem persists. 

Specifically, is your phone cable placed correctly and firmly to the wall jack and the modem port—is the cord damaged altogether? 

Perhaps you’re using a jack splitter or a microfilter. If this is the case, try plugging the phone cable directly into the router. Now, inspect your work and check if the lights are solid green.

8. Update Gateway Firmware

Sometimes outdated firmware causes blinking lights because you need to update the gateway firmware. It may also be the system updating itself, and you must wait until it finishes. 

In this case, you could see orange or amber lights as well. Once the firmware updates, you should be good to go.

9. Contact the AT&T Support

Contacting AT&T support is typically the last resort on the list. AT&T will have all the necessary equipment to run a diagnostic test to determine where the problem originates. Additionally, they can manually send a technician to your home to fix the problem.

AT&T Broadband Light Flashing Green Then Red 

An ATT U-verse broadband light blinking red and green usually happens due to the modem trying to connect to the network for more than three minutes. Blinking lights, in general, don’t mean a huge problem, but they could result in poor to no internet connection. 

However, the color of the blinking lights plays a significant role in the problem diagnosis. For example, a broadband light blinking green and then solid red means you went from a weak signal to no signal. 

Or, you went from having internet usage to none whatsoever because there was a system disruption. 

How Do I Know if AT&T Modem is Bad?

If none of the above suggestions fixes the problem, it’s possible your modem or gateway may be faulty. However, when a modem is on the fritz, there’s often more than one problem.

Here are some indicators that it’s time to replace your gateway or modem:

  • Your modem makes noises or gets hot
  • You’re having connection problems regularly
  • Various codes start blinking
  • Your modem turns off and on by itself
  • AT&T broadband light flashing red continually


Hopefully, we’ve provided you with the solution to remedy your AT&T broadband light blinking green. However, a defective modem or router can be the culprit, albeit rarely. A primary indicator is the AT&T broadband red light. In this situation, it’s best to replace the modem or router completely.
