Hi, since when I bought my device I have this problem,
Its the W007 MT6575 smartphone, it keep disconecting my wireless conection when I try to play an online game, doesnt matter if I'm on the side of the router.
Edit: for surfing on the browser looks fine, so hard to get a disconect.
It has this issue too to find conections at middle range, such a crap wifi hardware I guess.
But I'm here too know if there are maybe other way to improve my wifi, like on engineer mode, I saw there is other channels to change in wifi and frequency and other things...As you can see on this screenshots:
Information of my device:
Someone can help me? By the way sorry for my english I'm brazilian xD.
