Flashing Green Router Light

The red button on the back? I've done that about 5 times. Anything else it could be?

Hi cameronsdavis87,

Thanks for reaching out on the AT&T Community Forums! We'll happily help you learn what your Gateway lights mean and stabilize your Internet connection.

We can give you troubleshooting options to try on your gateway. You can try restarting and factory resetting your gateway. Here are the steps to restart:

• Unplug the power connection behind the gateway for ~15 seconds.
• Plug it back in and wait for the broadband light to turn green.

Here are the steps to factory reset:

• Locate the small red button & pinhole on the lower rear of the gateway
• Depress for ~15 seconds.

Also, the gateway status light chart that my thoughts provided should give you a good idea as to why the gateway is acting up. Please go through this article to understand your Gateway lights: 

• Green: The gateway is powered on. 
• Flashing green: The gateway is starting. 
• Amber: There’s a software update in progress. Don’t unplug the gateway or remove the battery until the update completes. 
• Red: The gateway or power supply may be malfunctioning. Try rebooting your gateway to fix it. 

We recommend you to please go through this article to reboot your Gateway by following these below steps:

1. Unplug the power cord from the back of your gateway or modem. If you have: 
   • An internal battery backup, remove it
   • DSL, unplug the phone cord from your modem or gateway
2. Wait 20 seconds.
3. Put the internal battery back in if you have one. 
4. Plug the power cord back in. If you have DSL service, reconnect the phone cord.
5. Wait up to 10 minutes for the gateway or modem to restart and your Broadband light to turn solid green.

Let us know if this helps.

Happy to Assist!

If the reset does not resolve then flashing green is waiting for activation of the ONT.

This was always performed by the tech, but as equipment was shipped to you for self install hopefully you have instructions how to activate the gateway ONT

Thanks everyone. I called the help line at 800-288-2020 and it was easily resolved in about 10 minutes. The tech was able to send a signal to my box and get it activated.
