Let me tell you about the hell that is Roku. They create so much wireless interference and I can’t just get rid of them.
The problem stems from WiFi direct. They automatically scan for the busiest channel and then broadcast full strength on that channel. I don’t know why they do this but it creates a crazy amount of interference.
And before you ask, no you can’t turn WiFi direct off. Also the remote uses WiFi direct for some reason.
WHY, ROKU WHY!
I have an Nvidia shield for now, and run Plex on unRAID. I will be moving to a HTPC one the shield goes tits up. For the most part, I consume my media from my PC, but if I’m using the TV, it’s currently my shield.
