Intermittent packet loss along coastal California, just south of San Francisco

We have been experiencing high packet loss, over multiple days, at our home in Montara, CA, just south of SF. This affects online work meetings, streaming services, video games, etc. Our home is fully CAT6 wired and we use Ethernet to all our computers to maximize performance, and we don't use any splitters that could degrade the signal quality.

It's extremely frustrating because we can't do anything about it beyond restarting our cable modem, which only occasionally helps.

We had an Xfinity tech come out and check the line to our home for signal quality and such. The day he was out here, it looked fine. That was several weeks ago. Now we're getting packet loss regularly.

More recently, Comcast did an overnight maintenance (IIRC on May 14), and that fixed the awful packet loss we were seeing. That lasted about a week. The past couple days, the packet loss issue has been occurring through the day.

We lived in San Francisco for years and never experienced these kinds of sustained issues.

The tech did say that with the salty air and wind that equipment degrades quickly. I get that. But what exactly is our monthly bill paying for, if the service is unreliable?
