I received the streaming stick 4 years ago as a gift. It is used with Wi-Fi only. I’m trying to minimize my Wi-Fi usage. I would like to get some thing I don’t know if it would be an adapter that would allow me to plug into the ethernet. I have a router and modem. I have no idea how I would even go about doing this. Do I need an adapter? Or do I have to buy an entirely different Roko device? Thank you
