Highly Intermittent Uploads

For the last around 5 months, I've been dealing with wildly varying upload speeds. At times, down as low as 0.15 Mbps. I've had a tech out, the line signals are good to my modem. The speeds can be good, but at times the uplink (wired connection) drops to the dirt, stopping applications such as games, causing an experience that is very inconsistent, slow and unresponsive. I've called tech support, got ahold of Tier 2 support but they disconnected on me in the middle of my call and they weren't available when I tried to call them back. This issue happens when I am hard wired directly into my router even though I use a separate modem as well. Discord audio is garbled when this happens along with other voip systems. Meetings I've been in have had interruptions or periods of disconnection. 

I've run tracert and pings to various network devices trying to determine where the issue might be but the results so far have been inconclusive. It doesn't appear to be device delays for the ping, but throughput congestion or traffic shaping that is almost cutting off the network and the applications that are using the internet are severely impacted. I am a network Engineer and I am frustrated with the inconsistency of this service. Does anyone have any ideas what might be causing these issues? There are no service impacting reports per the xfinity site but I find your automated tools and customer support lacking. Puyallup WA

I was watching The Seahawks, 49ers game on ABC streaming through Xfinity on that same wired connection a few minutes ago. Everything stopped, download speeds seem fine once the speedtest started working but the upload was .019 Mbps.

Hi, @Not2Wired! Our community is an awesome place to get to the root cause of this problem. We want your service to be stable and reliable! We appreciate the steps you tried as well as having a technician out. If you are wired to the modem are there no problems with the service? Do you have a high speed port that the modem is attached to at the modem?

I probably need another tech out. I had an appointment scheduled for Tuesday but I couldn't make it back from work in time so I cancelled it Monday night. I changed my router to a Xfinity rented router Sunday and today it started exhibiting the exact same behavior tonight. I have a screenshot of a speedtest that is  886 down and 0.46 upload. 

I have a desktop with a Cat8e cable plugged directly into the Xfinity router. I have another modem for wifi plugged in for the rest of our devices. I had tested on both devices and you definitely have issues with the service. 

As I stated, it is highly intermittent and when it chokes, it is internet stopping.

@Not2Wired We can certainly get something rebooked. Worst case if they cannot find the issue onsite the tech can escalate to the maintenance team if needed. Please send us a direct message with your full name and service address and we will get you rescheduled.

That image was not personal information. It was speedtest information showing 886.12 Mbps download and 0.46 Mbps upload. Looking forward to seeing what the tech finds today. This intermittent issue has been horrible.
