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?
This happened to my sister they apparently had excessive RF leakage apparently causing issues with radios etc in the area. Said they were about to disconnect them from the tap but luckily she was home and found it was a crappy coax connection.
