If that cap is part of a switch mode regulator, I will pay close attention, that the replacement capacitor has a low ESR. Otherwise you will get a huge ripple voltage on the power rail, this switchmode regulator is powering. So the oscilloscope won't start either, although there are maybe no other damaged components.
How did you measure the netgear supply's output voltage. If you did with a multimeter, then there is the possibility, that the actual peak output voltage is above 16V, because maybe the output ripple is several volts with no load. To confirm this, you'll have to measure the output voltage with a oscilloscope if you have a second one to hand. But pay attention that you don't make a undesired earth connection with the ground clip of your scope. Best you use a isolating mains transformer. See for more details
