What matters more is your internet speeds, Google WiFi is an AC1200 Router meaning it can handle up to 1200 Mbps, theoretical, internet speeds which is faster than anything available in most areas now. So you want to make sure your internet download speeds are near 25 Mbps or more because if they aren't then you won't be able to stream 4K on any device in your home. Even a computer on hooked up via an ethernet cable.
