A residential technician came out and verified that my inside wiring passes all static tests. However, my Netgear CM3000 is experiencing severe intermittent upload-only packet loss. My signal logs show my downstream is perfect, but my Upstream OFDMA Channel 2 is failing to lock (0 Hz / 0 dBmV), and Channel 1 is running on an exceptionally low transmit power of 37.8 dBmV. This is causing frequent Notice 6 Profile Flapping and T3 Timeouts. I need an escalation ticket submitted to the Outside Plant (OSP) / Line Engineers to balance the upstream carrier frequencies at the local node and check for upstream ingress noise.
