Common Causes

Are you dealing with an AT&T Gateway blinking white? Understanding the common causes can help you fix the issue quickly. Below, we break down some of the most frequent reasons behind this problem.

Power Issues

One of the most common reasons for a blinking white light is power issues. Ensure that your gateway is properly plugged into a power source. A loose or faulty power connection can disrupt its normal operation.

• Check if the power cable is securely connected.

If you still see the blinking white light, consider using a different power cable. Sometimes, the cable itself could be faulty.

Another common cause is firmware updates. Your AT&T Gateway might be updating its firmware. During this process, the light may blink white.

1. Allow the gateway some time to complete the update.
2. Do not turn off the gateway during the update.
3. Check the gateway’s manual or website for update duration.

If the light continues to blink after an hour, a manual reboot might be necessary. To reboot:

• Unplug the gateway from the power source.

• Plug it back in and wait for the device to restart.

In some cases, a firmware update might fail. If this happens, contacting AT&T support can be your best option.

Initial Checks
