Recurring packet loss since March 19, 2026 – multiple nearby homes affected, XB10 possible factor

I’m trying to get this properly escalated because normal troubleshooting has not fixed the issue.

Since March 19, 2026, I have been experiencing recurring packet loss and internet interruptions. The packet loss tends to happen in intervals of about 5 minutes, often with 10%+ packet loss at a time, and sometimes the internet stops working completely during those events.

I am monitoring this through my UniFi firewall, so I can see the issue at the WAN side and not just on Wi-Fi devices inside the home.

Troubleshooting already done:

• Xfinity has reprovisioned the modem multiple times
• A technician came out today and removed a filter from the coax line
• The issue is still happening after that visit

Important detail:

My neighbors started having the same issue around the same time. In his case, replacing the XB10 with an XB8 appears to have resolved the problem.

Because this affected multiple nearby homes at about the same time, I do not believe this is only a basic in-home Wi-Fi issue. I am asking for this to be reviewed as a possible local line/plant issue, signal impairment, upstream noise issue, or possibly an XB10-related problem.

Can an Xfinity employee please review this and help escalate it beyond basic troubleshooting?
