Packet Loss on a New XB8-T +install
I signed up for 800 mbps service last week and the tech came out to install the modem. Even though they are seeing 800+, when I do a speed test on a PC as the only connection to the modem, I get speeds of 360 max. I am using PingPlotter to look for packet loss and I'm seeing tons of it. AT the modem and at various hops along the way. Here's a typical report.
When I call the Xfinity "help" line, the support people don't know what Packet Loss is. Their solutions are for me to upgrade my service, or to just go away. I've been having buffering and glitches with all streaming services, even podcasts for several weeks. My initial contact about this was last week and his solution was to upgrade my service, so here I am, a week later with the same issue. How do I get this fixed? Mike

Thank you for reaching out. I hope you are doing well today, despite the issues with the network. I understand that at the time of the installation, the tech captured full speeds, but you have yet to see this on your end. Additionally, you've seen gradual packet loss affecting videos, streams, and podcasts. I'm sure this has been frustrating. I appreciate you bringing this to our attention and creating a new post.
I did check the levels at home, and I did see the upstream RX power wasn't up to par, but I didn't see any other red flags yet. Are you able to provide a screenshot of your most recent speed to gateway test?

I have tried connecting a high-end i9 windows PC to the modem, with this being to only connection. There is no improvement. I suspect that the issue is with the Comcast servers.

The Xfinity speed test shows 150.6Mbps today. What are next steps?

Not sure if you know but they can actually see the speeds you are testing at on the Xfinity speed test site on their end. So, they should be aware something is wrong.

New info for you. (I know this is company policy so I'm not blaming you. Just the opposite -- I know how big companies are, and I appreciate your help.)
When I initially went online @ Xfinity to get help about 3.5 weeks ago, I had been having these same connectivity issues for the prior 3-4 months. Eventually, the data loss was so great, that I worked through the Xfin site and talked to a chat-based technician. He said that he could see that my modem was old technology (it was working great 4 months earlier) and I needed to upgrade to a higher tier of service, which included a "current" modem. At that point, I had no choice but to upgrade. After the new modem was installed, and both on-site techs said that they did the best they could, we are still seeing the same problem I saw before upgrading. I seem to be getting a very choppy 150Mbps going through Comcast servers.
After I discovered that the new modem didn't help, I talked to tech support 3 more times and they all said that was they checked the modem and I needed to move up to a higher tier. This leads me to believe that I never needed a new modem at all and I was conned into upgrading on that very first call.

This shows an 85% packet loss at server "be-501-arsc1.capitolhghts.md.bad.comcast.net". This was reported three weeks ago. Why has this not been addressed?

I get the same run around. I was told my plan was obsolete and had to downgrade and it was which I thought was funny as i had been at 13.gbps for years and then had to drop to 1100mbps or the same price and the website showed 1.3,gbps was discontinued. Then a month later I called and was put back on 1.3 Gbps for $15 a month cheaper. So to tell you the truth I don't t many people have an clue on what is going on at the backend.

I've been working with Xfinity for almost 30 days trying to resolve a data loss problem that makes my new Xfin modem practically useless. (I have an 800Mbps plan with their newest modem, however all streaming services glitch to the point where my devices crash.
I have been handed off to ~15 techs and none of them know what to do. I have to re-explain the problem every time. My issue is beyond the knowledge base of the standard Xfin tech. I need an engineer to take a look at the issue and resolve this mess. How can we make this happen?

COMCAST SERVER "be-501-arsc1.capitolhghts.md.bad.comcast.net" IS BAD. The top large red area at the bottom of this screenshot shows practically continual packet loss
