I rarely see the main interface since I mostly stream with a ShieldTV, so I can't really say anything about ads there. I did finally end up enabling wifi though. I kept it off for the first month but the TV got more and more aggressive about posting overlays that warned my that my TV did not have internet access. Even while streaming on an external device. It really took me out of the moment. I probably would have returned it at that point but my car isn't big enough to fit it and any other TV would probably end up the same way or worse.
