Guys hopeless case, i have the same issue for the last 3 years and could not solve it at all. I reset the box, downloaded the original firmware, i made factory reset, i tried the new firmware lollipop rom1. i did all the possible things with no hope, the bluetooth works, the hotspot on the box works so antenna working 100% percent but no wifi at all, you put it on but can't find networks at all. I contacted the company a lot of times, i wrote on the forum with no help. I can't understand how it's possible that there is no way just to reinstall the wifi driver on an android. No one in the whole world could answer that, i mean where is the brains out there? With so many developers, geeks, hackers etc... No one can access a box drivers easily and fix a wifi issue. After so many years suffering from it, i finally got android TV which serves good so far but still trying to find a way to crack this wifi mystery. I did not let anyone that i know to buy minix boxes since i faced that issue, shame that the company did not care.
