CM2050V - Significant packet loss detected - Is my Cable modem failing?
It is suspected that the cable modem may be experiencing a defect and thus necessitate replacement. During the process of backing up substantial video files, ranging in size from 40GB to 80GB, to a c...
Attached is a diagnostic status sheet from my CM2050V I am running on Xfinity just outside of Seattle. What area are you located?
The first thing I noticed is you have only one upstream bonded channel and I have four.
Your power levels are closer to normal than mine. The local technicians tell me Xfinity is running the power levels in my area hot. They did not have an explanation as to why.
If you run a throughput test using the Ookla stand alone application, what up/down values do you get? On my setup, I average 1300/42.
Occasionally I upload 30-40 GB files to Microsoft One Drive. I am running an ASUS RT-AX88U Pro router and have not noted any packet loss entries in the logs.

My location is Woodbridge, NJ.
My down load speeds and uploads speed are good. The download speed hovers around 1000 Mbps - 1300 Mbps and the uploads speed (with the filter) hovers around 280 Mbps - 350 Mbps.
I use Ubiquiti equipment (router, switches, and APs).
You are connected to an area that has been upgraded to the Xfinity Enhanced Speed Network and your modem has a boot file that provides the full allowed upstream throughput. This is based on your throughput values and your OFDM/OFDMA channels. Xfinity is gradually releasing the boot files for the CM2050V to see if the new firmware has a negative effect on their network.
I would be curious about the specification details on the filter that was installed. A model number or a picture would be helpful if you can get it. It could possibly be an attenuator that the technician called a filter.
Back to the question in your original post, in my opinion there is no indication your modem is failing. Possibly both Xfinity and Netgear are being cautious about the recently released firmware for the CM2050V, and it still may need some fine tuning.
Kitsap,
Thanks for your input.
I'm not certain precisely when the issues began, but I recall starting to upload large files around late January. This coincided with Comcast's network upgrade to higher upload speeds, although the new firmware for the CM2050V was not yet available as it today. In early January, the upload speed were limited to about 100Mbps.
Attached is a file with two pictures illustrating the situation:
- The left picture shows my line within the junction box is tagged. Notably, out of the eight lines entering the box, mine is the only one that is tagged.
- The right picture shows the filter that has been added to my line. The filter's part number is SHP3-35.
An interesting point to note is that Comcast has performed at least two "planned maintenance" events in the last two months, specifically on April 11th and May 1st. They have also scheduled another "planned maintenance" for tomorrow, May 6th. All of these maintenance periods occur overnight between 1:00 am and 4:00 am.
Thank you in advance for any insight you can provide regarding this matter.
