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
