Upload speed not exceeding 40Mb/s -- Upstream OFDMA Channels not locked
CM2050V modem, achieving about 900Mb/s download speed, but only 40Mb/s upload.
Checked the modem and discovered that --while upstream OFDM channels are locked, downstream OFDMA channels are not (see below)
If they were, I would get higher upload speeds.
What has to happen to get these upstream channels locked ?
Thanks,
Wolf.

The CM2050V is compatible with their Internet and home phone services, but is still not compatible with the higher upload speeds they introduced in 2023.
See the "Next Gen" list at the top of the "All Compatible Devices" PDF linked near the bottom of https://www.xfinity.com/support/devices (at the moment it points to https://assets.xfinity.com/assets/dotcom/projects/cix-4997_compatible-devices/2025.03.25 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.
ETA: The year-old post at https://forums.xfinity.com/conversations/your-home-network/faster-internet-speeds-now-available-until-you-backdated-my-modem/65978b4f2e4f0f284530df88?commentId=659a8be32e4f0f2845312956 is the latest statement I know of from Comcast/Xfinity regarding CM2050V compatibility with higher upload speeds. The post is a vague "we're working on it" statement. You would think that, 12 months later, more would have been accomplished.
