AC68U Beeping?

[nfshp253]

My router has suddenly started to beep strangely after updating to the latest firmware. Everything works fine but it's just making that incessant noise. Anyone knows what the issue is?

Almost sounds like the hiss I experienced, when I initially upgraded firmware from 380 to 382 out of the box. After a factory default reset, using the reset button on back of router, haven’t heard it again. I could actually reproduce the sound by changing wireless channels on the 5Ghz channel.

Have you reset the router to factory default?

Anyone knows what the issue is?

Sounds a bit like the "ringing coils" of a switching power supply. Does it seem related to differing loads on the router?

Coil noise. Nothing unusual.
