Netgear CM3000 stuck at ~40 Mbps

My Xfinity Broadband Label confirms 117 Mbps typical upload for my Gigabit tier. I have a Netgear CM3000 (approved for Next-Gen speeds). My modem diagnostics show the Upstream OFDMA channel IS locked (Channel 1, 47.3 dBmV), which I think means mid-split is active. However, my upload speed is stuck at ~47 Mbps. From a bit of research, I think this means my modem is running a legacy provisioning profile/bootfile. I need a Tier 2/provisioning engineer to:

  1. Review my account plan codes and confirm I'm on a Next-Gen speed tier
  2. Force-push the Next-Gen Speed Tier / OFDMA Upstream Profile bootfile to my CM3000's MAC address

Please DM me for account details. Thank you!
