A red light that blinks is not a good thing. It’s especially important when the problem is with your internet equipment. You rely on it to work, watch your favorite shows, and do other things. Stay calm. If the red light on your AT&T broadband is blinking, there are some common reasons and easy solutions.
What Does a Red Light on AT&T Broadband Indicate?
If your AT&T broadband is working properly, you will see a green light on the modem gateway. When the light is flashing green, it indicates that the gateway is starting up. When you see an amber light, it means that a software update is currently happening. If there’s a red light, it could mean that the gateway or power supply is not working properly.

Reasons
If the red light on your AT&T broadband is blinking, it could be due to a problem with the server connection, equipment, power supply, or something else. When the red light appears, it means there are problems with the internet or connection. However, there is usually a simple solution.
1- AT&T Network Is Down
If there is an AT&T service outage in your area, the red light may blink. You can find out if there’s an AT&T internet outage in your area by searching on the AT&T website using your zip code or account information. If your computer or tablet’s internet isn’t working, you can use your cellular service to access the website. You can sign up for outage alerts on your AT&T account page to receive notifications if there is a service disruption in your area.
2- Check the Power Supply or Connection
If your modem or router is blinking, it could be because the power supply is not consistent. If there is no power, the system will turn off and there won’t be a blinking light. Make sure your power cord is securely plugged into the outlet or power strip. Also, check that the cords connecting your modem or router are properly connected.
If you have been using your power strip for more than three years, it might be time to replace it. This is because power strips usually work well for only three years. It’s better to connect your modem and router directly to a wall outlet.
3- Hardware Issue
If you added something to your modem and are having problems, that thing you added might be causing the problem. To test the equipment, remove it from the modem and check if the light is still blinking. If it’s not working, it’s probably because of hardware that isn’t from AT&T.
Your AT&T gateway might have a problem, although it’s not very common. If you hear a strange humming noise or loud connection sounds along with a red light, it could mean that your gateway is not working properly.
4- There Is a Major Network Device
Your AT&T internet provider should allow you to connect multiple devices to the network simultaneously. If one of your devices is causing trouble, it may affect your gateway. If you lose service at a particular time of day or when you use a specific device, it could be an indication that the device is causing the problem. To find the problematic device, unplug all devices from the network and then plug them back in one by one. Check which device causes the red light to blink.
5- Update Firmware
Firmware that is old can cause problems too. To update, you can use the AT&T app or connect your computer to the AT&T gateway to check for updates. If it doesn’t work, you can reset your gateway to the factory settings. Note that this action will delete your personalized preferences. To reset your router or modem to its original settings, press and hold the reset button for 15 seconds. To reset the device, trigger it and wait for the light to turn green.
6- Contact AT&T Broadband Support
If you’ve tried everything to fix the problem but it still persists, you can contact AT&T customer support for help. You can find solutions to AT&T’s internet problems on their website, and they also offer chat and phone support.
