its mostly down but it does come back on sometimes for a few minutes but its very random. Yes completely down modem lights that are on when its working turn off like the online light goes from blue to off, ds and us go off and turn to green blinking light but that's from what i remember. Its not like the internet slows down i test it all the time and i get 60+Mbs it just turns off.
That isn't congestion, your modem is actually de-registering. Ask the Tech Support folk why your modem de-registers every day.
