High pitched whine noise from new Arris NVG589

I have a new NVG589 as well, and there is a high pitched whine noise coming from it BUT I can only hear it in a quiet room with my ear within 1 inch of the RG. Depending on the length of the connected cables/wires, try moving the RG around - it might be picking up some electrical interference from an outlet or another device. OR...since it's new, contact your installation tech and state that your RG is defective.

I recieved a brand new one and mine does this as well....

Does it still produce this sound when you disable the NVG589's wireless?

I know that a few devices make a low noise whine sound when there is wireless activity.

I also have this problem with the high-pitched whine.  I worked with an AT&T rep yesterday and we tested two NVG589's.  Both had the high-pitched whine. We tested them disconnected from the power source and running only on the battery--still had the high-pitched whine.  We tested it without the battery and only running on the power source--same result, even without any lines connected to it.  It takes a minute or two to warm-up, then starts humming.  I went as far as plugging it into a neighbor's home, just the gateway, and it still whines, after warmup.

The solution-- we placed it in a cabinet to buffer the sound.  New problem--the outside walls of the cabinet are now warm to the touch.  I'm not comfortable with this amount of heat.

I believe that Arris must have had a bad batch of gateways, since this whine does not seem to be common problem for them.  I will be calling AT&T to try others, hopefully from a different batch.

I also have this whine when the wifi is off. I can hear it sitting anywhere in my office which is about 12x12 feet. If I throw a blanket over the router, the noise is mostly gone, but it gets very hot and I'm not leaving it like that for fear it will start a fire.

I called AT&T and they would not ship me a replacement, they want a tech to come out, which is quite inconvenient as I have to be home to meet them again.

I have kept the NVG589 RG in the cabinet (to muffle the whine) for three days now.  It gets hot and heats up the cabinet, but I don't believe it is enough heat to be concerned about a fire danger.  Other electronics in that cabinet do warm up from it, which I do believe is a concern; and hence, I've moved them away from the RG.  The whine is still pronounced when the cabinet doors are open.

My access to the internet has dropped (during use) every morning since switching to the NVG589.  Interestingly, the power, battery, wireless, broadband1, broadband2, and service light remain green.  The phone1 becomes disconnected.  It doesn't seem to reset itself, and requires me to do a reset with the button on the back of the RG to get online and phone again.  I wonder if this is an issue with the RG or the AT&T service in my area.  Looking forward to input from others.

I called AT&T and they told me that they weren't aware of the problem. They clearly didn't believe me, so I made this video! https://youtu.be/SN1sx2uv_Bs
