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!
Not sure if it’s what the previous commenter meant, but Onn is a brand owned by Walmart.
