MT8733 upstream stuck at ~6 Mbps, same as an old thread
I'm hitting the exact same problem as this thread: https://forums.xfinity.com/conversations/your-home-network/upstream-only-6mbps-with-motorola-mt8733-provisioning-problems-12gig-service-plan/6620501312df8b16cf69f155
Motorola MT8733, plan 1000/100. Download is fine (~650 Mbps), but upload is stuck at ~6 Mbps.
Already ruled out the usual stuff: signal is clean (upstream 42–44 dBmV, 0 uncorrectable), tested wired directly to the modem (not Wi-Fi), line already fixed by a tech, and I've power-cycled several times. My event log also shows "UCD invalid or channel unusable."
Same as that thread, how should I handle this?
