Sound high frequency on the modem DPC3925

[ferreirasf]

Hi, I got a modem DPC 3925 and I saw that the modem emits a sound as a mosquito after three or four hours turn on. I turned off the equipment from energy oftentimes, but the sound restart after three or four hours turn on. I don't know if this is a normal behavior, I don't believe. Can anyone help me? Thanks!

I guess the sound may have something to do with impedance mis match ( radio elements ) . However , elements like capacitor and transistor gates also generate noise.

Is your dect phone place close to the cable modem, someone did mention that the dect n the wireless are causing some interferences.

If not then go to SH to exchange if still under warranty.

There are not much choice for devices on cable, only cisco DPC3925 n motorola SB6120 support DOCSIS 3.0. SB6120 is just a cable modem and nothing else.

Don't think u can just purchase a cable modem outside and use cos SH have mac address control, u can only use devices from SH as other devices u could not submit the mac address for processing.
