Intermittent internet and television service interruption.
I have been experiencing intermittent internet and television service interruptions for the past several weeks.
These interruptions last anywhere from 5 seconds to 1 hour, and present as nearly 100% packet loss and garbled freeze frames from the cable box.
I experienced this a 3 years ago when I had business internet from Comcast. It was explained to me by the regional support agent (whose name and number I have lost) that was sent out after 3 regular tech visits that this is due to interference on the cable line causing the modem's upstream power to peak and trigger the safety shutoff. For the record when this happens modem upstream power is peaking at ~56 dBmV.
The cable line from the pole to my house is only 3 years old. This occurs with the Xfinity Gateway whether it is in bridge mode or not.
After dealing with the useless Xfinity Assistant chatbot for the past several weeks I come here as a last ditch effort to actually be able to talk to a human being at Xfinity about this.

@Anon1210784, Thank you for your post. Do you get any text messages or app notifications that there is an issue in your area when this happens? There can be many causes for intermittent service like this, so I don't want to jump to conclusions and possibly miss important details.

You'll want to get the techs reinvolved and keep pressure on Comcast until things are fixed properly.
Bear in mind that if the premises facing techs can not find or fix a problem at your home, it is they who are responsible for escalating it up to their line / network / maintenance dept. techs. The problem may lie beyond your home in the local neighborhood infrastructure somewhere but it is their S.O.P. to start at the home. And if the problem is found to be on their side of the demarcation point, there will not be any charge.
Good luck !

Had the tech out Monday. He agreed with my evaluation: external interference coming in. Replaced the drop because that's standard procedure. Also enrolled my modem in an enhanced monitoring program to take more regular/advanced measurements from the modem to check if there are other issues stemming from the line. I still firmly believe that the issue is on the Xfinity line, but with the advanced monitoring I am hopeful they gather enough data to track it down.
Still waiting on the results from that however.
