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?
If you have a spare coax cable that you can use for testing (even if it is a short one), try swapping it out, and see if your blue lights come back on.
I've had borderline / intermittent coax cables in the past.
