Are you wondering why the AT&T BGW320 blinking red? Stay with us throughout this guide!
- The blinking red light on your BGW320 gateway is only one of the possible indicators that could impact the network device.
So, knowing what each color of the LED lamp indicates is critical to troubleshooting the BGW320 gateway and restoring the functionality of the network and Wi-Fi!
Whenever the AT&T BGW320 gateway blinks in red, you must check the connection with the service ONT and power cycle the network device.
If the issue persists, identify any ongoing AT&T service outages or outdated subscriptions and factory reset the gateway.
There is much more to learn, so let’s get started!
Why is the BGW320 Red Light Blinking?
The red light indicates a potential connectivity error between the BGW gateway and the AT&T service box and causes the network to go offline until further notice.
Hence, the red light on the gateway can occur in two states, and in all cases, it indicates a particular functionality problem.
Here are the primary causes for the red blinking light on AT&T BGW320:
Let’s understand more about the blinking patterns on your AT&T BGW320 gateway!
| All AT&T BGW320 Blinking Patterns | |
| WHITE (solid) | Indicates that the BGW gateway is online and the connection to external servers is reliable. |
| RED (solid) | The AT&T gateway could be overheating or has developed a potential hardware issue. |
| RED (slow blinking) | The AT&T network is offline due to installation or service issues. |
| YELLOW (only for phone lines) | Indicates that one or more of your voice lines is offline or has a connection problem. |
Those were the possible causes for the blinking red light on the gateway and what the different blinking styles of the lamp indicate.

AT&T BGW320 Blinking Red – 5 Quick & Proven Solutions
Tip: Follow the steps in chronological order.
1. Power Cycle Your AT&T Setup
You can address AT&T gateway and service box issues by power circulating the device’s HW.
This is an effective remedy against any hardware or software issues with the gateway and can restore the connectivity to the AT&T ONT service box.
How to Power Cycle the AT&T BGW320 Gateway?
- Unplug the power adapter of the gateway from the wall.
- Disconnect the other end of the cable from the gateway.
- Wait for 60 seconds while the BGW320 is discharging.
- Reinstall the power adapter of the device into the outlet.
- Connect the other end of the cable to the electrical port.
How to Power Cycle the AT&T Service Box?
- Disconnect the Power cable from the service box.
- Unplug the other end of the cable from the outlet.
- Wait for 60 seconds while the wire is unplugged.
- Reseat the adapter on both ends after the cycle.
- Finally, wait until the AT&T service box reactivates.
How to Locate the BGW320 Service Box?
If the BGW320 gateway uses an extended Ethernet cord and the service cable is not nearby, follow the service cable all the way to the service box’s location.
The unit is generally installed on a wall next to an electrical outlet for easy user access and filtration of wireless interference.
Tip: Inspect the power cord of either device for damages while unplugged!
2. Check for a Local AT&T Outage
The next step is to check if an ongoing service outage with the provider has impacted the AT&T service in your area.
You can receive accurate outage information about AT&T and DIRECTV services through the online Outage Checker, accessible through AT&T’s Official Web Page.
Follow these steps to inspect if there’s an ongoing AT&T service outage:
- Open a web browser on your mobile or computer device.
- After that, access the official AT&T website at “att.com.”
- Tap on the “Outages” button from the homepage of AT&T.
- Click the “Sign In” button under the “Service outage info.”
- Sign in to your AT&T client account with your credentials.
- If prompted, enter your Residential Location on the field.
- Once logged on, you will be forwarded to the outage table.
The outage table will bring up all AT&T and DIRECTV outages happening now and provide you with information about the service status in the last 24 hours.
You can always contact AT&T Customer Support to request status information on the AT&T service within your area.
Are the Service Box Lights Green?
Another way to tell if your AT&T service has been suspended is to pay attention to the indicator lights on the service box.
Thus, during the guide setup through the AT&T mobile app, you will be reminded to check if the service cable’s lights are solid green or whether they blink alternatively.
Note: A red light on the ONT service could also mean that the issue is outside your home!
3. Reconnect the Gateway Service Cable
The BGW gateway uses two mandatory cables to connect to a power supply and service to the “Ethernet” port on the ONT.
If the data transfer of the service cable is disrupted, the gateway may suddenly lose connection to the service box, and the indicator LED will start blinking red.
Follow these steps to properly reseat the BGW gateway service cable:
- Disconnect the service cable from the “ONT” wire on the box.
- Unplug the other end of the cable from the BGW320 gateway.
- Inspect the service cable’s physical condition for impairments.
- Connect the service cable to the “Ethernet” port on the BGW.
- Reconnect the other end to the “ONT” port on the service box.
If the service Ethernet cable no longer transfers information due to a defect, you can purchase a replacement or order a brand-new Ethernet cable online.
There aren’t any preset preferences towards a specific cable as long as it is compatible with the “ONT “port on the AT&T service box.
Note: Verify that the new Ethernet cable is RJ-45 or CAT-5!
4. Reactivate Your AT&T Subscription
The BGW320 blinking red light is also set to occur whenever your AT&T subscription expires.
Not completing scheduled provider payments on time will temporarily deactivate your service and cause the gateway to blink in red until the AT&T subscriber status is restored to “Online.”
- To renew your AT&T subscription, sign in to your user profile through the official website and go to “Change my Plan.”
Once in the “Plans” section, you can either re-subscribe to your current plan or choose a new plan with other perks and benefits listed in the information bubble.
After choosing a subscription, you must follow the steps to include your personal and payment information.
Note: Verify that the associated payment source has enough funds to cover subscription costs!
5. Factory Reset the BGW320!
Performing a factory reset on the BGW320 gateway will erase all system and network settings, including service transcription and transfer issues.
Remember that all lost information as a result of the factory reset cannot be saved or restored later for repetitive use.
Here’s how to perform a factory reset on the AT&T network gateway:
- Verify that the BGW320 gateway is plugged into power.
- Next, locate the reset button compartment on the back.
- After that, open the factory reset button compartment.
- Use something thin, such as a paper clip, to reach in.
- Hold the reset button of the gateway for 10-15 seconds.
- Finally, release the button once BGW enters reset mode.
You will know that the gateway has entered the reset mode after the LED light on the frontal panel goes off or starts blinking in an alternative way.
How to Complete the Initial BGW320 Setup?
To set up the gateway initially after a factory reset, all you need to do is connect the device with an Ethernet cable to your computer device and access the web GUI.
To access the GUI, copy and paste “https://192.168.1.1/” into your browser and sign in using the AT&T login credentials.
Alert: The AT&T Wi-Fi networks will be erased due to the factory reset!
Quick Recap:
To resolve the AT&T BGW320 blinking red, simultaneously power cycle the service ONT and the gateway.
If the issue persists, reconnect the service cable, check for an ongoing AT&T service outage, inspect your equipment, and factory reset your BGW320 gateway.
