I think it's a real shame that a manufacturer such as Netgear routers delivers a top with such a scrap PSU. Now I have 3 different routers of the same type ausprübiert and all 3 had the same sufferings ... The power supply is a very disturbing and loud, high-pitched tone of itself ... absolutely not suitable to be used in continuous operation -.> Return ... will probably not buy a Netgear product more!
