Screen Mirroring is not working. I have a Netgear Nighthawk Dual Band router.

Some of our users have reported screen mirroring problems with the Netgear Nighthawk router. It turns out there is a problem with network traffic between the 2.4Ghz network and the 5Ghz network.

For optimal performance of screen mirroring with your Netgear Nighthawk dual band router, connect both your Mac and your TV to the 2.4Ghz network.
