My Netgear CM3000 upload speed capped at 40 Mbps.

My Netgear CM3000 diagnostics show that the upstream OFDMA channel is successfully Locked at 36.2 MHz (Power: 43.3 dBmV), proving my modem hardware is fine. However, my upload speeds are still capped at 40 Mbps. This confirms my modem is stuck on a partial or legacy bootfile. Please have a Tier 2 network engineer review my account provisioning codes and force-push the correct Next-Gen / Mid-Split speed tier configuration file to my modem's MAC address.

Multiple techs visited my home and they couldn't fix the issue. field technician verified my physical line is capable of high upload speeds, but my speeds are capped at 40 Mbps. Also, multiple front-line agents couldn't solve it either.
