I moved into my new Lennar home about four years ago. Recently one of the ceiling boxes has started showing a red 'PWR' light only. When I unplug it from the main control box, it will resume working/show flashing or stable green lights, but a day or two later it will return to red status. The other box seems okay. I am unable to connect to an Unleashed Network through the app in order to troubleshoot. Of note, I recently upgraded to a new modem/router combo - but as mentioned, one of the boxes still works as expected.
