Hi David,
Wow that is unfortunate! I've also suffered from a lot of the Oreo bugs on my Mi Bo but fortunately for me wifi disconnection was not something that happened a lot. SInce this latest update it hasn't happened once, but I am disappointed to see that there are still occasional stuttering and freezing during video playback. This was never the case on Marshmallow.
I believe there is a 'main' mi box thread somewhere were we can post out bugs on the latest update but at the moment I am not sure where it is. I'll let you know if I find it, could you also let me know if you end up finding it?
