Ongoing issues after neighborhood upgrade - how to get resolution?

I am experiencing ongoing connectivity problems that started/worsened after a recent neighborhood line upgrade work in my neighborhood.

Previously, Xfinity replaced the drop line from the outside box to my house twice.   The second time with a tech visit to inspect the outside box and a threat to switch internet providers given inability to reliably work from home largely resolved my issue.  The problems returned after the recent "neighborhood upgrades".

This is something where I do not want the drop line replaced again and them to tear up my lawn. I would like a technician to inspect the outside box/junction and the plant work that was recently completed, as the symptoms point to noise/ingress beyond my home.

Current symptoms and evidence- I have detailed logs to support this as needed over last week

• Frequent Critical T3 timeouts (“No Ranging Response received”)
• A major event around 1:16 AM on 10/23/2026 involving Loss of Sync, T2/T3/T4 timeouts, RCS/TCS Partial Service, Lost MDD Timeout, and the modem re-initializing
• Continuous CM-STATUS Event Type 16 and 24 (OFDM profile failure/recovery) on Channels 193 and 194
• Frequent upstream OFDMA profile changes on Channel 41

Current signal status (as of today):

• Downstream QAM channels: generally clean power (~0.5–2.3 dBmV) and SNR (~38.6–39 dB)
• Channel 193 (OFDM): Power 3.0 dBmV, SNR 42.0 dB, ~175M corrected errors, 159 uncorrectables
• Channel 194 (OFDM): Power 2.2 dBmV, SNR 41.0 dB, ~200M corrected errors, 2,505 uncorrectables
• Upstream: All channels locked at ~44.5 dBmV

The combination of high OFDM error counts, ongoing profile flapping, and upstream ranging failures (especially the full re-registration event) is consistent with plant or junction issues introduced or exposed by the recent upgrade work. Power and SNR levels look acceptable, so a simple “levels are fine” remote check will not address this.

How can I get Xfinity to schedule a technician to inspect the outside box/junction and the recent neighborhood work rather than replacing the drop line again. I can provide the full modem log if needed but don't want to waste time going through the basic troubleshooting given the past history and current fact pattern. 

Thanks in advance.
