A while back I had a small adventure.. http://www.dslreports.com/forum/r29412628-Large-upstream-power-level-change-after-3hr-outage.
During the troubleshooting, a tech placed an EQ on my line. (on the house side of the grounding block) At that time, he said that my issue was upstream, and the EQ might make a tiny improvement until it got fixed. Also saying that after the fix occurs, I should probably remove the EQ. It is one of these...

I left it on the line for a week, recording a new baseline for 'normal' signal levels.
Last night, the internet went down during the maintenance window, so I thought it would be a good time to remove the EQ from my line. The results were horrific to say the least.

My signal levels were NEVER that bad, even before the repair.
I tired rebooting the modem, to see if the signal levels would reset, but they did not. I put the EQ back on the line, and we are back to normal. Now, before you say "You didnt get his coax reconnected properly after removing the EQ." Know that the EQ is now connected to my modem, and not the grounding block outside. Meaning, the outside connection is as well connected now, as it was while the signal was measuring bad.
So the end question is... Should I have left it off longer? Does it take time (longer than 45minutes) for my modem and the head end to re-evaluate signal levels and readjust? Or is this a sign of something else wrong?
PS:
The only reason I want to remove the EQ, is that every little thing in your line between the grounding block and the modem, (splitters, long coax, etc..) results in signal loss, albeit small. I would like to do whatever I can to keep my SNR as high as possible.
