AT&T U-verse NVG589 modem/router high-pitched noise

**UPDATE July 7, 2015**
Replacing this modem with a refurbished one (NVG589; same model) from Feb 2013 eliminated the high-pitched noise! My original modem was from Dec 2014 and made the horrible noise. The first replacement we tried was from May 2015 and also made the noise. 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).

**original description**
My AT&T U-verse Arris NVG589 modem/router (dated Dec 2014) makes this high-pitched noise whenever it's connected to the Internet, and it has done so since it was first installed in June 2015 (i.e., since it was brand new). It's extremely annoying and I can hear it from a room away. When I contacted AT&T, they told me they weren't aware of the problem and sent me a replacement modem (same model) that made the same noise. A technician is supposed to come by and check it out soon; my only hope is that they can replace it with a different model, because this noise is driving me insane!
