Re: Roku media player need wifi to play off a usb stick?
No, it does not. But your media must use supported codecs and be in a supported container. Roku players have limited support for codecs or containers. I would need to know what model Roku you have to know for certain what it supports.
Of course, for all current models of Roku players only the Ultra has a USB port.
Dan Roku Stick (3600), Ultra (4640), Ultra (4670), Premiere (3920), Insignia 720p Roku TV, Sharp 4K Roku TV, Nvidia Shield, Windows 10 Pro x64 running Serviio and Plex on a wired Gigabit network.
