# AT&T Router Blinking Red: Meaning & How to Fix (Broadband Light)

**Is your AT&amp;T router blinking red?** This status usually indicates a connection failure with the broadband network or a detected power issue. Whether you are using an AT&amp;T Fiber gateway (like the BGW320) or a standard DSL modem, a flashing red light effectively means your internet is down.

In this guide, we explain exactly why the broadband light blinks red and provide 10 proven steps to get your connection back online fast.

## Key Takeaways

- The AT&amp;T router shows a blinking red light when it cannot connect to the internet. A variety of hardware or software-related issues may cause it.
- In most cases, a fiber outage in your area, a power supply issue, or an issue with the ONT or modem could be the reason for the red light on your AT&amp;T router.
- You can resolve the issue by rebooting the router, upgrading the firmware, resetting the device, checking the ONT for problems, and confirming whether an AT&amp;T outage is in effect.

## Fixing AT&amp;T Router Blinking Red Issue

To fix the AT&amp;T router blinking red issue, **restart** your router and check for network outages. If the problem persists, you can perform a **factory reset** and set everything up again. You can also contact AT&amp;T tech support for a replacement.

## What the AT&amp;T Broadband Blinking Red Light Means

Before we proceed with the steps, it is helpful to understand the meaning of the blinking lights on an AT&amp;T router. We do not want to bore you with an exhaustive list, as it would include the steps for multiple AT&amp;T router models. Instead, here is a quick look:

- **Blinking Red Light** on your AT&amp;T router means the router cannot connect to the internet. It may also refer to troubles with the router battery.
- **Blinking Green light** on your AT&amp;T router indicates that the router is attempting to connect to the internet. You will see this status when you turn on the router. It is best to wait for a few minutes.
- **Blinking Red/Green light** means the router is updating its firmware. This process happens from time to time, and you should not disconnect or turn off the router.

You must keep in mind that these meanings are part of a broader concept related to AT&amp;T routers. You can rely on these meanings as soon as you have the **BGW320**, **Pace 5268**, **NVG599**, **NVG589**, and **BGW320** models at your disposal. However, the specific lights for other models might vary. Therefore, check the model number and user manual if you encounter a confusing combination of LED status lights.

So, while a blinking red light on an AT&amp;T router indicates that the router cannot connect to the internet, it does not pinpoint the specific issue. Therefore, we must identify the potential causes of the problem to fix it.

- AT&amp;T **fiber outage** in your area or across the country
- Connection issues with your **[Ethernet cables](https://datafeature.com/ethernet-cables-types/)**
- Issues with the **power supply** unit of the router
- Your AT&amp;T router could be **overheating** or **overloaded**
- Additional **hardware issues** with the router
- Problems with the **fiber ONT** or **modem** from AT&amp;T

As you can see, multiple reasons may cause the flashing red LED light on your AT&amp;T router. Since we cannot be specific about any of these reasons, I recommend adopting a systematic approach.

## 10 Effective Ways to Fix AT&amp;T Router Blinking Red

In this method, we will attempt to address the most common issues before moving on to the more advanced ones. Therefore, if the problem can be solved by rebooting or power cycling, you do not need to put in additional effort.

### \#1 Reboot your AT&amp;T Router

As with most errors, the blinking red LED can be resolved with a reboot. A **hard reboot** will resolve temporary connection issues and enable the AT&amp;T router to reconnect to the network.

To **[reboot the AT&amp;T Wi-Fi router](https://datafeature.com/automatically-schedule-reboot-wifi-router/)**, you can press the Power button. Alternatively, you can unplug the power cable, which would turn off the router. Then, when you reconnect the power cable, the router will turn back on.

### \#2 Check Connection Cables

If you still see a blinking red light after rebooting the router, you should check all the **connection cables**. First, you should check whether you have correctly connected the [**Ethernet**](https://datafeature.com/what-is-ethernet/) cable. Two, if there is a fiber ONT, it should also be connected to the Wi-Fi router properly.

It is a good idea to restart your Wi-Fi router after checking all the cables. By the way, if you still use a coaxial internet connection from AT&amp;T, you should check whether the cable is functioning correctly.

### \#3 Check the Power Supply and Power Cycle

It is equally important to check whether your AT&amp;T router receives the recommended power. Therefore, it is a must to use a compatible power supply system. It is ideal to use the power cable that came with the router. If that is not possible, you should check the power requirements of the router before proceeding.

Equally helpful is **[power-cycling your router](https://datafeature.com/power-cycle-your-router-modem/)**. This process takes your AT&amp;T router through a form of software reset. In my experience, power cycling has resolved multiple issues. To power-cycle your router, disconnect all cables, including the power cable.

Then, you can reconnect these cables before connecting the power cable. The steps take only a few minutes and can effectively resolve internet connection issues.

### \#4 Check for AT&amp;T Fiber Outage

Before you go any further, check whether there are **AT&amp;T fiber outages in your area**. In worst cases, the ISP may face countrywide outages as well. If there is a network outage, you have to wait until it is solved. All these steps will not help you until that happens.

You can find the current status of network outages on AT&amp;T’s official website. It’s also a great way to stay ahead of any network outage that may disrupt your routine.

### \#5 Run a Router Firmware Update

Firmware issues with your router can also cause the blinking red status light. There are two sides here. One, you cannot intervene in this process. Router firmware updates are released by manufacturers or **[ISPs](https://datafeature.com/best-internet-service-provider-in-usa/)**, such as **AT&amp;T**. On the bright side, ISPs typically handle firmware-related issues well.

![Router Firmware Update - ATT Router Blinking Red](https://datafeature.com/wp-content/uploads/2024/03/router-firmware-update.jpg)If you regularly experience the flashing red light issue with your AT&amp;T router, you should run a firmware update. You can do it by logging into the router **dashboard** &gt; **settings** &gt; **firmware update**. The update may take a few minutes, and it is essential not to turn off the router during that time.

### \#6 Fix Overloading/Overheating Issues

You should optimize the AT&amp;T router’s location to avoid overloading and overheating. It is also a good idea to check whether you have **too many devices connected** to the router. If you see a blinking red light when too many devices are on the network, you may want to reduce the number of devices.

### \#7 Check the ONT

Often, the AT&amp;T router blinking red issue is caused by a connection issue with the ONT. So, you should check if the **[ONT](https://datafeature.com/optical-network-terminal-ont/)** is **working correctly**. Once again, you may have to check the recommended LED lights from the manual. If you find a serious issue with ONT, you may have to contact technical support.

### \#8 Factory-Reset Your AT&amp;T Router

If you find no issues with ONT but are still stuck with a red blinking light, the last resort is to factory reset your AT&amp;T router. Since you may not have access to the network, we suggest the most straightforward method for [**resetting your AT&amp;T router**](https://datafeature.com/reset-att-router/).

1. Locate the **Reset button** on the rear side of the router
2. Use a paperclip or SIM ejector tool to **press the button**
3. **Hold** the button for at least **10 seconds**
4. When the router lights start blinking, you can **release** it
5. Now, **wait** until all the router lights are back to stable

While this step will delete saved information, you can have quick access to the AT&amp;T network. Refer to the user manual or product box to check the default password and Wi-Fi SSID.

### \#9 Get AT&amp;T Technical Support

If you do not have luck even after factory resetting your AT&amp;T router, you are left with a few options. I recommend contacting the company’s official technical support. Depending on the arrangement, you may receive a replacement router or get the current one repaired.

In my experience, AT&amp;T customer support is pretty quick. As long as you make an appointment, they are on time, and you should have your internet connection working in time.

### \#10 Use a Third-party Router

If continuous changes to the AT&amp;T router do not help, you can go for this option.

With some additional steps, you can use a **[third-party router with your AT&amp;T connection](https://datafeature.com/best-routers-for-att-internet/)**. This setup may not offer the same level of optimization as the company-provided one, though.
