I have an ASUS AC68U wireless router and lLgitech G930 wireless headset, and I kept finding that my headset with drop out. After some research, I came to the conclusion that I should try changing the wireless control channel on my router.
The control channels range from 1 to 11, so the best options to avoid interference are 1, 6 or 11 (i.e either end or the middle of the spectrum). I tried 11, then 6 and both weren’t much better, however control channel 1 seemed to do the trick. You can tell it works because a restart of the wireless on the router after changing the channel would cause a drop out, and this happened immediately on channels 6 and 11, but not on 1.
