I recently had a sb6190 modem which I took back to best buy in exchange for a netgear cm600. I'm trying to figure out if my modem signal levels have any issues or if they're around where people would expect.
A little background.. My setup use to be (street cable box coax cable -> 3 way splitter -> coax cable into grounding bridge piece -> coax cable to modem)
I was told that my levels have a swing in them and so I was told to try seeing how it would look with out the splitter and without it, the levels are 8-12dbmv, etc. which i guess is a bit on the hot side? so I was told to get a -6db atteunier piece to replace the splitter with, but it keeps everything right around what the splitter was doing already.. Now I'm being told to remove the -6db piece and let it run 8-12dbmv and such, so I'm a bit confused here since I lack the know how of modem signals, etc.

Those are what my levels look like, left is without splitter but using the -6db piece and right is without splitter and without -6db piece. Wondering which setup I should use for now in the mean time before I get a tech to come out and replace our street cable box coax cable with a new one to see if that's what the cause of the swing is.. cause everything else aside from that has been fully replaced with new stuff.
