Well... I factory reset my Roku 3 two additional times, and re-paired the remote each time (this is on top of the initial pairing after factory reset).
That brings the totals up to:
3 Factory resets, (Fun fact: Having to link my Roku to my account without
the benefit of wi-fi is sooo much fun. I know I need to exercise, but running from the room with the Roku to the nearest room with a wire connected PC wasn't the kind I needed.)
4 remote re-pairings (on top of the three with factory reset),
And my Roku 3 is still
squashing the living daylights out of my wi-fi network.
Despite my Roku having no contact with my wi-fi router, and considering I am a glutton for punishment, I went ahead and factory reset my wi-fi router. What a major PITA that was... Had to break out an ethernet cable and get to the router... Not the wisest suggestion by the way.
Still no joy. As long as the Roku is plugged in, my wi-fi network is jammed by Roku's WiFi Direct.
So, at least today, there is a user who has this problem that factory reset didn't even come close to fixing. Check here: viewtopic.php?f=28&t=74898
So what now Mister Wizard?
What other hoops can I jump through to convince you it is an issue with the Roku 3? Or, at the very least, MY
Roku Engineers: Post hoc ergo propter hoc. Which is Latin that apparently means "even if you can provide evidence to the contrary, it never happened. Simply because I can quote Latin."
I bet this post gets me another board warning too!
