If you have any splitters, attenuators, or amplifiers in line, I'd recommend removing them.

Also get a screen snip of the cable connection page showing all the upstream/downstream info. 

Post that back here.

Re: connection dropping dynamic range window

you're upload link speed is to low and you have errors on the downstream link 

If they haven't, the isp needs to check the line.
