AT&T BGW320 blinking green light, and you’re wondering why? Well, this guide covers everything!
- The AT&T BGW320 Wi-Fi gateway uses 2 different LED indications, which sometimes appear green, blinking, or solid.
In this guide, we will understand the different green indicators on your BGW320 Wi-Fi gateway and how to solve them based on whether the blinking is fast or slow.
To fix the blinking green light on the AT&T BGW320, verify that your gateway is activated and perform a power circulation. Next, connect your Wi-Fi device correctly, or wait at least 2 minutes for the WPS setup mode to disable.
Let’s unwrap everything in more detail!
Understanding the BGW320 Flashing Green Light
On your AT&T BGW320 Wi-Fi gateway, there are 2 different LED indicators that may produce the blinking green light.
First, there is the Service LED, which could blink in green, and there is the WPS LED, which blinks in green (slow) or (fast).
Hence, the first step is to identify whether you’re observing a blinking green light on the Service or WPS LED.
The Service LED is on the front of the device, while the WPS LED is right on top of the WPS button, so make sure to find out which one it is.
Based on your findings, here’s what the green light means on the BGW320 gateway:
| AT&T BGW320 Green Light Indicators | ||
| Indicator: | Pattern: | Meaning: |
| Service LED | (fast blinking) | The gateway is connected to the network and ready for activation. This only occurs during the first installation. |
WPS LED | (fast blinking) | The gateway is undergoing a factory reset, so please wait until the device automatically restarts. |
| (slow blinking) | The WPS button has just been pressed, so please take action on your connection device to establish a link. | |
| Ethernet LED | (solid) | The port has been connected to the device, and if this LED is off, your unit is not connected correctly. |
| Power LED | (solid) | Your Wi-Fi gateway is powered on and currently working. |

How to Fix the BGW320 Blinking Green Light Easily?
Tip: Follow the solutions chronologically!
1. Activate the BGW320 WiFi Gateway
So, if you’re at the first-time installation of your AT&T BGW320 gateway, then after connecting the device, you’ll see a blinking green light.
This means the gateway is connected to the service box (network) and is ready for the initialization process.
To set up your AT&T BGW320 gateway, you’ll need the following:
The AT&T Smart Home Manager app is available for Android and iOS, so if you still have not downloaded the software, feel free to do so now.
Then, sign in to your account, verify that you have an existing AT&T account to log in to the application, and complete the setup initialization.
How to Activate BGW320 Wi-Fi Gateway
Here’s how to activate your BGW320 gateway when everything is setup:
- Locate the AT&T service box in your home.
- Verify that the service box is powered “ON.”
- Open the AT&T Smart Home Manager app.
- Then, tap on the “Set Up Equipment” button.
- Scan the QR code on the BGW320 gateway.
- Tap on the “Get Started” button in your app.
- Connect the ONT cable to your service box.
- Info: The box may have a cover you must lift.
- Connect the ONT cable to the Wi-Fi gateway.
- Connect the gateway to the electrical socket.
- Follow the steps in the Home Manager app.
- Wait for the BGW320 gateway to update fully.
- Name your network and complete the setup.
Note: If the setup succeeds, the blinking green light should turn solid white!
2. Switch to Another Power Source!
If you see a blinking green light next to the power connector on the AT&T BGW320 gateway, it’s possible that the device is not receiving a sufficient power supply.
The A/C LED indicator should always be solid green, and when the LED blinks in green, the A/C source may be inconsistent.
So, the best way to overcome power fluctuations from the source would be to verify that your AT&T Wi-Fi gateway is connected directly to the outlet.
So, remove any third-party connectors such as electrical extenders, power dividers, or smart plugs.
Tip: If the Power LED blinks green, connect your gateway to a different outlet!
3. Power Cycle the BGW320 Gateway
If you have carried out the AT&T BGW320 gateway first-time setup previously, but the service green light started to blink unexpectedly, this may be a system bug.
Hence, you should perform the power cycle process on your gateway to refresh the system and resolve any minor glitches.
Here’s how to power cycle your AT&T BGW320 gateway:
- Press the Power button to turn off the gateway.
- Then, unplug the gateway from the power outlet.
- Wait for 60 seconds with the gateway unplugged.
- Then, reconnect the power cable on both sides.
- Verify that the Power LED is illuminated in green.
- Turn on your gateway and wait for it to load fully.
When your AT&T BGW320 gateway is fully powered on, check whether the Service is flashing in green, and if yes, try to activate the gateway again.
If the activation fails and the gateway blinks green, continue with the next step…
Note: The power cycle will not erase anything from your AT&T BGW320 gateway!
4. Reinstall the Smart Home Manager
The Smart Home Manager app is the fundamental aspect of the BGW320 gateway activation, and if the Service LED is still blinking green, the activation has failed.
So, to verify that the app is not causing issues with the activation, we recommend uninstalling and reinstalling the app.
Here’s how to uninstall and reinstall the Smart Home Manager app:
- First, find the Smart Home Manager app icon.
- Then, press and hold the app’s icon continuously.
- On Android, drag the app icon to the Trash Bin.
- On iOS, select the “Remove This App” option.
- Then, open the Google Store or the App Store.
- Next, find the “AT&T Smart Home Manager” app.
- Then, tap the “Install” or Cloud + Arrow button.
- Wait for the app to get installed, and then sign in.
When the Smart Manager app is downloaded and installed, and you’re signed in, scroll up and use the activation steps from earlier in the guide to set up your AT&T BGW320 gateway.
If the activation process succeeds, the Service indicator will switch from blinking green to solid white.
Tip: Verify that your AT&T Smart Home Manager app is up to date!
5. Connect via WPS the Correct Way!
If the AT&T BGW320 gateway WPS button is blinking green, then the button has been pushed, and the WPS Mode has been enabled.
This means that you must now interact with your WPS device, which you want to connect with, to complete the WPS setup and establish a connection.
Typically, the WPS setup works by pressing the WPS button on both devices within 2 minutes so they can communicate over the network and connect effortlessly.
If you’ve pressed the WPS button accidentally and now it’s blinking in green, you must wait a while or restart the gateway.
Tip: You may discover more instructions about the WPS setup in your Wi-Fi device’s manual!
6. Factory Reset the BGW320 Gateway
The final and best solution against the BGW320 flashing green light is factory resetting your AT&T gateway.
This will completely reinstall the operating system of the gateway and will provide you with a fresh opportunity to perform the initialization process, which should help!
Info: The WPS LED light will start blinking in green during the factory reset!
Here’s how to factory reset your BGW320 gateway in easy steps:
- Verify that your BGW320 gateway is powered on.
- Then, locate the Reset button on the back panel.
- Press and hold the Reset button for ∼20 seconds.
- Then, wait for your gateway to restart automatically.
When the factory reset is completed, the Service LED light should start blinking in green, which means the gateway is ready to be activated.
So, scroll up in the guide and use the steps in the beginning to correctly activate the gateway, which will change the blinking green to solid white.
Tip: If you cannot complete the activation, contact AT&T Customer Service for help!
Quick Recap:
Hence, the BGW320 blinking green light can be fixed by correctly activating the gateway through the AT&T Smart Home Manager app.
If the blinking green is on the WPS button, you must carry out the WPS setup from your WiFi device or factory reset your gateway.
