Re: Connection going from normal to very slow every 2-3 days
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.
