As i was reading through the forum, i noticed that quite some people have the low wifi bandwidth problem on these devices, especially on AP6210 chip. It is connected but nothing goes through, or hardily goes.
Anyway, the chips on motherboard are generating a lot of background noise, and since the internal antenna is almost sitting on it, the signal gets damped.
Just open your device and move the antenna away from the motherboard. Get it out from the housing and let it hang there.
