Avoid using Ethernet with tvOS if DFS wifi channels are used

Normally, when deploying Apple TVs, you want to connect them to the network via ethernet. Like all hard and fast rules, there is one big range of exceptions. Apple TV should be connected to the network over Wi-Fi instead of Ethernet when using DFS channels on the Wi-Fi network and peer-to-peer AirPlay is desired.

 

Dynamic Frequency Selection Channels

When a DFS–enabled radio is operating on one of the following channels, the wireless device uses DFS to monitor the operating frequency and switch to another frequency or reduce power as necessary:

  • 52 (5260 MHz)
  • 56 (5280 MHz)
  • 60 (5300 MHz)
  • 64 (5320 MHz)
  • 100 (5500 MHz)
  • 104 (5520 MHz)
  • 108 (5540 MHz)
  • 112 (5560 MHz)
  • 116 (5580 MHz)
  • 120 (5600 MHz)
  • 124 (5620 MHz)
  • 128 (5640 MHz)
  • 132 (5660 MHz)
  • 136 (5680 MHz)
  • 140 (5700 MHz)
