[Signals] Why do signal levels change?

Click for full size
Just a question about levels and why they change.
I had to move my desk around and had to powered down the modem and router.
Moved them both about 3 feet.
Before the move my SNR was 38 across the board with power levels of 0 across the board.
These are the levels after the move. Nothing changed other than the 3 foot move.
I know the level are still good, but just wondering how that could be. The upstream power didn't change.

Re: Signals

may have change the angle of a bend/damage/normal wear and tear on the cable, or changed the torque on the connector or maybe moved the modem to a spot slightly better shield from some source of interference.
Also by power cycling your modem may have reset it's error counter and now believes your SNR is better.
(it will likely edge back down over the longer term)
Luckily your signals look great so minor fluctuation shouldn't effect you.

Thanks tshirt.
I see what you are saying.
Not worried about the signal levels, just curious.
