Netgear CM2050V upload speed not performing

I have a Netgear CM2050V modem and currently have the 2000mb/300mb and am only getting 41mb upstream. A technician has come out and validated everything up to the modem. Upon researching the issues, there was a bug in the CM2050V a year ago or so. The issue was corrected and then apparently firmware was downgraded due to stability issues. The issue was to be addressed within 90 days or so. We are now a year down the road and I have this issue. Can you provide any insight? Do you just need to push an updated firmware down?
Thank you.

araposo8 Thank you for following up with us and letting me know the technicians findings. With our gigabit x2 speeds the upload offered is 300 Mbps. I'm sorry that you are not seeing that speed on your devices. I know how important it is for our services to deliver 100%. I would love to help out and make sure that we have this corrected.

I am seeing a similar problem with my CM2050V, using Gigabit Extra in an Enhanced Speed/Network area. I am in San Jose, CA, and my neighborhood was upgraded this past summer of 2024. My CM2050V is running firmware V10.01.03, and on Gigiabit Extra, I should receive 1300/300 (under the new plans announced on March 11, 2025). Xfinity support told me that the CM2050V is NOT approved for Enhanced, yet I have seen others on this forum receive a resolution to the new speeds. My speeds are consistently 1200/41Mbps. I have power cycled the modern, and no difference. Can I get some assistance and clarification? I really appreciate any help you can provide.

... CM2050V, using Gigabit Extra ... I should receive 1300/300 ... My speeds are consistently 1200/41Mbps ...

The CM2050V is compatible with their Internet and home phone services, but not with the higher upload speeds they introduced in 2023. See the "Next Gen" list at the top of the "All Compatible Devices" link near the bottom of https://www.xfinity.com/support/devices (at the moment that link points to https://assets.xfinity.com/assets/dotcom/projects/cix-4997_compatible-devices/2025.03.06 Full List of Compatible Devices.pdf, but this changes from time to time).

Comcast could make all of this much simpler and clearer, but they have chosen not to do so.
