I have had a cable modem for more than a year now, but recently something strange has started to happen.
I’ll be sitting on my computer (well, on the chair in front of my computer), and all of a sudden, my modem will make a short slide-whistle type noise. It’s a short, almost muffled sound like a slide whistle going down in pitch.
This has only started in the last few months. Does anybody else have this?
