AT&T BGW320 Blinking White Light: Causes And Effective Fixes

Seeing the AT&T BGW320 blinking white is normal when you turn on or reset the router. However, it shouldn’t last long and ideally, the AT&T router LED light should turn solid white at the end, indicating that the device is online and ready for use.

However, sometimes your router can get stuck in the blinking white state which is something we have to pay attention to if it lasts for longer than usual. In this article, we’re going to explain what are the frequent causes of the BGW320 blinking white light issue, what it means, and most importantly, how to solve it.

Why Is My BGW320 Blinking White?

If the white light continues to blink for an extended period, it could indicate a problem. This can be caused by several different reasons:

  1. Connectivity issues – Connectivity issues often occur because of your ISP (in this case AT&T) or a problem within your home network.
  2. Firmware update – the blinking white light can also indicate that an automatic firmware upgrade is happening at the moment so it’s better just to wait a little. The light should turn solid white when the upgrade completes.
  3. Hardware issues – A faulty or damaged router can also be the reason for the white blinking light.

How To Fix The BGW320 Blinking White Light Issue

Finding the right solution for the BGW320 blinking white light issue can be somewhat difficult, but we did our best to make the process as simple as possible.

Here are some solutions for you to follow and if you are unsure whether or not you should try some of them please get in touch with AT&T support and ask for their assistance.  

Don’t Act Immediately

Although this might not seem like a solution, sometimes you just have to give your device some time. Sometimes there is a temporary glitch or your ISP was doing some changes in the configuration that prevent your router to connect properly.

Potentially, there is a firmware upgrade going on at that moment and you shouldn’t interrupt the process in any way.

Just wait for some time (20-30 minutes) to see whether the issue will resolve on its own or not. If the LED light is still blinking after that time try the following solution.

Restart Your Gateway

Restart your BGW320 gateway

The first thing to try whenever you are experiencing issues with your router and other electronic devices as well is to restart the device. You can press the power button at the back to do this, but we prefer disconnecting the power cable from the electrical outlet.

This should shut down the router completely. Plug the power cable back into the router after 2-3 minutes and pay attention to whether it will go past the white blinking light and eventually turn solid white.

You can also restart your router using the Smart Home Manager app.

  1. Install the Smart Home Manager on your smartphone or tablet and sign in.
  2. Select Network.
  3. Now scroll down a little and choose Home Network Hardware.
  4. Tap on the Wi-Fi Gateway and choose Restart.
  5. Confirm your decision by selecting Restart again.

If the LE Dlight on the router is still blinking white after the restart, it is time to move on to the next potential solution.

Check Your Cables

Sometimes, the issue isn’t with the router itself, but with the connections it relies on. Therefore, you need to check all the cables connected to your BGW320:

  • Confirm that each cable is securely plugged in.
  • Look for any visible damage such as cuts, severe bends, or fraying.
  • If any cables appear damaged, consider replacing them and see whether the white light is still blinking.

If all your cables are in good condition, but the light continues to blink white, it is time to try the next solution.
