I have used this router for the last few years and just upgraded. It works well but does have a high pitched coil whine that my wife doesn't notice however I do if the router is under 5-6 feet away. The coil whine doesn't affect the performance, but make be irritating if you have sensitive ears and are close to the router frequently.
