Someone on FB said it went from docsis3.1 to 3.0. the down light is supposed to be blue. Randomly moving the modem a certain way I can get it blue but only a few seconds. It's also making my speeds almost dial up speeds. Is there a way to fix it?
Double check your model. I have an Arris, all four green is what i want to see. Flashing is an error/synching
