    I have used several different cable modems in the past and I don't remember any of them making noises. My current modem though, makes a kind of static-like buzzing sound (not too unlike the sound of a HDD, but more high pitched) whenever there is any kind of internet activity, like for example downloading a file or loading a webpage. Is this normal, or should I give my ISP a call? My modem is a RCA DCM425.

    It only buzzes when they have the camera on and are watching you.

    It probably has an internal fan, which would be making the noise. You should pay attention to see if performance degrades when it's making noise--the fan might be failing.

    I too think it's an internal fan that's probably slightly off kilter. You could try power cycling and or shaking it just a bit to see if the fan reseats properly; but as long as there isn't any performance degradation, and the noise isn't unbearable, I wouldn't worry too much.
