It seems we both have the high packet loss problem. Question for you -- you said the packet loss got really bad in the last 2-3 months.... Is it possible that you downgraded your service recently? I did and it appears that was the culprit combined with this thing called Bufferbloat. Try and turn on Quality of Service or Bandwidth Limits in your router and put the MB/s at or just under what you are paying for from Comcast. It fixed my problem. When I turn on QoS with the limits, problem goes away. As soon as I turn it off, problem back. Back on again, problem gone. Check out on the web about Bufferbloat, but limiting bandwidth of your router to match what you are paying from Comcast seems to fix it for me. Interesting if it could fix it for you.
