Random Packet Loss / Noise

Hello,

I have been experiencing this issue off and on for almost 6 months now. I've had 5 techs come out and replace cabling outside the house and/or putting an attenuator on/removing and then test, saying there were no issues after making changes. Well, shortly after they left, the issue came back. I've told numerous technicians/support reps ignore the fact that I have tried three different modems and had my cabling redone multiple times, as well as that this issue has happened before and it affected my area and not just my house.

The issue itself is intermittent packet loss. During these times, the SNR and power levels fluctuate. The issue was resolved at one point. A tech that was scheduled to come to my house called me to tell me that there was nothing that he could do, and that technicians found an issue somewhere in the area that was affecting several other residents in my area. They performed work (not sure what - I think he said something about an amplifier) and the issue was resolved. Then, a month later, the issue returned and has been slowly getting worse since then.

Here is the status on my modem currently:

Is it possible to check other customers in my area and confirm that they are experiencing the same/similar issues? I am confident there is a wider issue going on in my area, especially since the one tech said that there was nothing that he could do, that there was an issue on equipment in the area, and that it was resolved later that day.

Someone please help. I am tired of this terrible service on both the technical and customer service side. I am already looking into other ISPs and am very close to switching to another provider.

Thank you.

Thanks for posting on our community forums, @user_dxomb4. I appreciate the detailed information. I'm sorry that this has been a persisting issue without a resolution. We'd like to help get to the bottom of this. To confirm, since the last technician, have you completed any self-troubleshooting? Checked the coaxial connection on both ends (wall plate and modem) to make sure it's tight and there's no damage on it, and rebooted the modem manually or through the Xfinity App.

I (and a technician) have checked all physical connections, inside and out, and there are no issues. The only thing they haven't checked is the connection on the pole. I have rebooted the modem multiple times (as well as replaced the modem twice, per my original post) and the issue is still present.

The issue seems to happen most often during peak usage hours. Most recently, between 10:00 am - 4:00 pm, and sometimes between 4:00 pm - 8:00 pm. It has been more frequent lately as well.

On my most recent phone call to support, the technician indicated that some other customers in my area had reported similar issues and there has been a ticket open for an issue in the area for a long time (more than 30 days), but there has been no recent activity on it.

This is getting to the point where I cannot rely on my internet connection for work or pleasure, and it's incredible frustrating.

Is there any way someone can help me look at the open ticket in the area and escalate the issue?

Thank you.

A technician came out today and saw water in the line coming from the tap, so he replaced it. However, the issue still persists and I am still getting random packet loss. Here is the status of the modem after replacing the cable from the tap to the house:

Also - not sure if this is relevant, but thought I'd throw it out there. I am paying for the gig service (1000/20) and I never get above 800 Mbps download, even when wired directly into the modem.
