Your Home Network

Location: Christiansburg, VA (served via Blacksburg-area network)

Problem: Intermittent packet loss and connectivity drops every evening ~6:30–10 PM for months. Affects Discord voice (drops to 1-2 red bars), Rocket League, Dota, Battlefield, etc.

What has already been done:
- All CPE replaced (including exterior hardware and XB8 gateway)
- Problem continues on direct Ethernet to the XB8 (rules out my router and Wi-Fi)
- Modem signal levels are in range (downstream ~6 dBmV, SNR 41–42 dB, upstream ~45 dBmV)
- Restarts do not help

Evidence:
- Continuous PingPlotter monitoring shows 0% loss on hop 1 (gateway 10.0.0.1)
- Packet loss and latency spikes begin at the first Comcast hops in the Blacksburg area
- Xfinity’s own system previously flagged DOCSIS Health Red + Network Intermittency
- Short real-time checks and 4-packet pings often look clean (as expected with an intermittent peak-hour issue)

Tickets:
- CR273466011 – escalated Aug 25 to plant/node team, promised 24–48 hr update, later closed as “fixed” with no resolution or contact
- CR274014899 – created Aug 29 after follow-up. Agent confirmed no CPE tech would be scheduled and that the advance team would contact me

I am not looking for another modem replacement or standard tech visit. The data points to a local node congestion or plant impairment issue that only appears under evening load. Requesting a proper plant/node review of the serving area.

Happy to provide PingPlotter CSVs or additional details if needed.
