OK I find the problem (and solve-it ;-). 

In the bios there some (very strange for me) configuration for the wifi
card, it seem it's same card to handle wifi and bluetooth. And when I pres
Fn+F2 he switch to bluetooth and my laptop crash...

So because I don't have any bluetooth device I don't use it. After
disabling bluetooth in the bios everything work fine.

So that answer my question about change to current...

Yes I known ;-)

OK. When I've some time I going to do this.
