Modem making high pitched sound

Modem making high pitched sound

I have an NVG589 modem which was recently installed. It's making a completely unbearable high pitched sound while it's on. It's been giving me headaches and the only solution is to unplug the modem. Does anyone have the same problem or have any solutions. Any help is much appreciated!

I have the same problem! I contacted AT&T and they told me they weren't aware of the issue. They didn't believe me (and couldn't hear the noise over the phone), so I made this video: https://youtu.be/SN1sx2uv_Bs

Re: Modem making high pitched sound

Update: I'm finally free of the high-pitched noise! The modems have a date printed on the side of them. My original NVG589 was from May 2015 and it made the noise. They sent me a replacement modem (same model) from Dec 2014 and it also made the noise. Finally, a technician came by. He had a refurbished modem (again, NVG589) from Feb 2013 and it *doesn't* make the noise! (Actually, it seems to make the noise extremely quietly, but the important thing is that I can't hear it unless I put my ear right up next to it, whereas I could hear the other one from down the hall!) So this appears to be a problem that affects NVG589 modems made between Dec 2014 and now, possibly going back as far as March 2013 (but the cutoff date is not clear).

Re: Modem making high pitched sound

So what should I do about this? Should I get a new one?

I have no noise issues with my NVG589, and it is dated 1/29/2015.

It would be interesting though to poll the dates of those having noise issues to see if it is a certain batch related issue rather than a random defect.

Re: Modem making high pitched sound

I just got a NVG589 install earlier today. I didn't notice anything immediately after install, but after I got home work later today this high-pitched noise you are describing was there.

 

I definitely need to get this thing replaced because it will drive me insane if I don't. My model looks like it was Dec 2014. Same month you are talking about. Maybe it's isolated with some batches as mentioned in this thread, but this is definitely annoying.

Re: Modem making high pitched sound

I have the NVG599 model, its wider and taller than the 589 and it makes the same high pitched whine noise. Is there anything I can do to make it stop? Can I put it in the entertainment system drawer or something or does it need to be out in the open?

Re: Modem making high pitched sound

I have this issue and need to resolve it. Has there been a solution found? I had ATT come to the house. The techs were able to hear the noise. They replaced the modem but they found that the new modem made the same noise. I may be going back to Time Warner if this can not be resolved.

Re: Modem making high pitched sound

This is a design flaw made by arris. Replacement also makes this high pitched frequency noise when pulling data down +10Mbps over WiFi only. This is likely a voltage regulator improperly tuned which creates low-frequency noise when pulling current from main power rails of system, which to human ear sounds like high pitched noise or audible harmonics (~18-19khz) Unfortunately I cannot pay for this cheap faulty arris hw and att’s goofy SW, going back tomorrow and canceling.
