--- Quote from: obob ---idk, i haven't studied much into the workings of cable internet, one of the few things I can't find a ton of literature on, I know it was showing very low negatives before line amplification, and would lose signals, and now with line amplifcation, it's showing low positives...so I was wondering if the amplifier sucked, but then forgot that it can work with negatives...whatever, i'm not going to question it as long as it keeps working...

 On the contrary: if you never question, you never learn.  We've offered what insight we have on the matter, but it might be best to pursue it elsewhere for a more detailed explanation.  Google is your friend, but if you know somebody that works for a major player they might have more of an idea regarding the subject.  :)

true, true however i think i've got a bit much on my plate regarding stuff to read up on...

some day...

--- Quote ---Q: What should my modem levels be? (#1084)   
A: Receive: -15dbmV to +15dbmV
Transmit: 30dbmV to 55dbmV
Carrier/Noise Ratio: >30dB

The closer to the center of the spec, the better (for receive and transmit).

As you get closer to the edge of the spec, you might start to see some connectivity problems.

Note: signal strength does not really affect speed. So as long as you aren't getting disconnects/pauses/packet loss, you probably are ok, even if you are nearer the edge of the spec.

A lot of ISPs lock you out of the diagnostics specifically so you can't read the signal strengths and complain.  If you're ever in a situation like that and you call a 'tech' and they do a remote reading telling you, "everything looks good" ask, "No, but what are the exact readings?"  Good to them can mean one or two degrees above or below failing.
