Gig Internet keeps dropping to 20mbps

Asking here since there is no phone or chat support available. Ever since I upgraded to gig speed six months ago, I started to have tons of problems.

 

My cable modem (Netgear CM1150V) is unable to keep a steady connection. So I replaced it, and still the same problem. After 50 phone calls, Comcast finally came out and replaced the drop line in my yard. It did not fix the issue. I replaced two splitters and coax cables (Beldon rg6 full copper), and did not fix the problem. The cable modem is connected near the drop line.

 

. My internet keeps dropping from 1000mbps to 20mbps. I have to restart the modem at least 4 to 5 times a day.

 

Can someone tell me if something is wrong with the cable connection stats below? Thank you
