Recurring intermittent outages — high downstream power, requesting line/tap inspection

Here you go — cleaned up and forum-safe:

I'm experiencing recurring intermittent internet drops on my Comcast Cable connection (2 Gig plan). This has been ongoing for roughly a month and is documented with router-side logging, not a vague "feels slow" complaint. I've already power-cycled and factory-reset the gateway multiple times with no change, so I've ruled out my own equipment.

EVIDENCE:

Uptime: My router logs 94.4% WAN uptime over the past month — roughly 5.6% downtime. That's far outside normal.

Recurring drops (router-logged events):

• Chronic low-level packet loss as a baseline throughout the day, with acute spikes on top.
• Packet loss recurring at nearly the same time four nights running, drifting about a minute later each day — suggests a scheduled network-side process or a recurring noise/ingress source.
• Full WAN drops also recurring in the overnight window over the same period.
• An outage tonight around 9 PM during active use (not overnight) — so this is also hitting prime-time usage, not just off-hours.

Signal readings from the gateway (taken this evening):

• Downstream power: primary channel reading +12.2 dBmV, other channels ~9.4–9.6 dBmV. This is above the -7 to +7 dBmV spec — the downstream is running hot, with a ~2.7 dB imbalance between the primary and the other channels.
• Downstream SNR: 38.8–41.0 dB (healthy).
• Upstream power: ~39.8–40.3 dBmV (healthy).

INTERPRETATION: Upstream and SNR are clean, but downstream power is over spec. Combined with the chronic packet loss and recurring drops, this points to a physical line issue — a problem at the tap, a bad/corroded connector or splitter, or insufficient attenuation on my drop. Not a congestion issue (peak utilization ~2% down / ~11% up, nowhere near saturating the line) and not customer equipment (the pattern predates all my equipment changes).

REQUESTS:

1. Please dispatch a technician to inspect the physical drop, tap, connectors, and splitters, and check/correct the downstream power level.
2. Please confirm whether there's scheduled node/CMTS maintenance on my segment, given the regular overnight cadence.
3. Please check for upstream noise/ingress on my segment.

Happy to share screenshots of the router WAN event log and gateway signal tables on request.
