Panoramic WiFi router not working

Our internet randomly went out yesterday.  None of our devices can connect or even find our WiFi. Panoramic router alternates blinking green for a few seconds, then orange for a few seconds, over and over again.

We did all of the resetting, unplugging, etc. and did troubleshooting over the phone with cox support. Nothing worked and they can’t send a tech out for a few days. What could be the issue that this would happen out of nowhere? If I could troubleshoot this myself without having to have someone come into my house, that would be awesome.
