I think i found what causes wifi to drop and reconnect all the time. As most of you know turning on best wifi kills the battery. But if you leave it off, and choose one of the frequencies 2.5ghz or 5ghz, wifi is super stable and also no dropping. I figured this out about an hour ago and don't have an app to test batrery, but i can already tell its better than having best wifi turned on. Hope this helps. 5ghz is faster but with shorter range. 2.5ghz is the oposite.
