Constant network jitter with spurts of packet loss
Hi,
Over the past year I've run into issues with abnormal network jitter and packet loss. I've had Xfinity come out to take a look at the configuration and we went as far as replacing the coaxial cable from my house to the xfinity box. It definitely reduced the frequency but never resolved the problem but I let it slide because it was marginally better. After a year, we are back and worse then before. At anytime of the day (used to be fine during work hours), I have high network jitter coupled with packet loss. Looking for some assistance on the forums as a last resort. I tried talking to the support staff on call with no luck. Yesterday, I tried to get it escalated but i don't think the support staff and I were on the same page, they just wanted to send another tech out.
Let me know how I can help get to the bottom of this issue!

We did not come to a conclusion on the root cause of this issue but I am choosing not to investigate it any further. During the debugging process, I randomly started seeing less frequent and less intense ping spikes (still happens but the applications are able to adjust better at this periodic) and because of that, I am satisfied. One item of note is if anyone experiences an issue like this one is to run tracert (windows) or tracepath (linux) to determine the RTT time of packets at each hop as it goes to the destination. If I decided to go further, this would have been a key metric to evaluate and I had a good conversation with the support staff when I provided my results.

I should also add I tried both DOCSIS 3.0 & 3.1 modems last year and DOCSIS 3.0 gave me the least amount of jitter so I have been using that modem (Motorola) ever since.
