I mistakenly installed the header with arm7 and removed it replacing it with header of raspberry. I doubt it isn't this problem.
I doubt is the kennel not match the driver.
So is there any solution to fix it? Or I have to buy a new wifi adaptor?

Do you have the headers for you kernel installed?

[Sequencer]

I have only installed the Raspberry Pi's Header
$this->bbcode_second_pass_code('', '

I wander if i should install the ARM v7 header for Pi 2

YOu shouldn't need dkms package at all with rpi kernel. The driver is in the kernel.
