My ISP is cable. Called and said they needed in my house to find the source of the signal that was affecting everyone else in my neighborhood. Literally nothing had changed and my house has been connected since 2010.

The tech arrived and I had them start outside. He replaced every connection/coupling and kept testing. After all of them were replaced, his testing machine showed a perfect signal. Noise eliminated. I was not charged for this service.

I found this baffling. My neighbor’s coax connections affect me?

Same thing happened to me,
But the noise was intermittent 2 minutes every 10 or so. It was upstream channels, so tech suspected it was someones modem failing.

No way to find out who's modem without shutting them down in groups in process of elimnation.

Took about 2 days and my upload was eventually returned from 100k back to 10mb
