I removed the wifi chip.
I found the motherboard diagram on www.s-manuals.com
Tablet Samsung GT-N8000 Galaxy Note 10.1 3G - Service manuals and Schematics, Disassembly / Assembly
to remove the chip was not easy, because I don't have the correct tools but any way I did it.
that solve my problem.
thank you.
(bluetooth is removed permanently to because the wifi chip control that to)
