I'm a sony employee, hard wired connection to your router will give you a steady connection while downloading the huge 4K content file. Therefore, we recommend using the Ethernet cable . However, if hard-wired will not work for you, we are suggesting the powerline network adapter so you can get a wired connection from your router to the FMP-X1 easily. You could try a wireless bridge; however, they might have performance issues depending on a number of factors that we cannot predict. We have not heard any current plans to provide a wireless version of FMP-X1; however that doesn’t mean that we will never provide this option.
