CM3000 Not Locking Upstream OFDMA – Upload Stuck at 63 Mbps on 2 Gig Plan
CM3000 on Xfinity 2 Gig plan. Download is correct (~2313 Mbps), but upload remains ~63 Mbps. Modem shows downstream OFDM locked, but zero locked upstream OFDMA channels. Router bottleneck already eliminated with ASUS RT-BE92U. Looking for verification that my modem/account/node is correctly provisioned for next-gen upload speeds and upstream OFDMA.

Update: During a technician visit, I was informed that while the node serving my area has been upgraded, the FDX/enhanced upstream connection has not yet been completed. As a result, the upstream OFDMA connection cannot properly lock, preventing delivery of the advertised enhanced upload speeds associated with my service tier.

Didn't mention. Ticket has been escalated, so I am told.
However, at the same time Xfinity sold me a service that wasn't available. That's an unfortunate business practice.
