Yes, if you're at -20dbmv, you have a line issue.
Move the modem right where the coax comes into the home and direct connect it.
See if that works. If it doesn't, then its something exterior to the home causing the issue and the isp needs to come check the line.
If it connects, post a screensnip of that cable connections page. It'll let us see how the incoming signal is and if its something interior to the home you need to work on or if the signal is still poor.
