Re: Connection going from normal to very slow every 2-3 days
said by tshirt:Well, now it's -8 and it does say
downstream power is pretty low, COULD be a potential problem, depending which way it swings. SNR looks ok for such low power. Upstream looks ok.
For all modems: -10 dBmV to +10 dBmV "Recommended".
The main thing I don't get is why is my speed going from normal for 2 or 3 days to super slow for 2 or 3 days, back and forth like that?

A 3.5dBmV fluctuation in signal on any given day is totally within normal range.
so assuming your modem is exactly right about the level(it's not a precision meter, but a "close enough" sort of reading) depending on exact when you took the reading, it could actually be down at -12 or so part of the time, throw in changing temps/seasonal manual adjustments, and you could have such a low signal that your modem is constantly saying "sorry, I didn't hear that, please say again" continual resends could explain the bad performance days.
It is borderline enough to make it worth calling in for a tech and fixing/adjusting it before you totally lose contact.
