Up.
My Asus N76VZ with Intel Centrino N-2230 has got the same problem.
Drivers are the latest (17.1.0) and i am using Windows 7 64 bit.
I try to change all value in advanced settings, but no result. My wifi still drop connection and goes in "limited connection" (small yellow triangle in the wi-fi bar, don't know the exaclty name in English). I have to disconnect and reboot the pc all the time.
Now i am trying to install the driver from Asus server...let's see.
I hope someone can fix the problem...of course this is a driver problem. Regards.
EDIT: Installed drivers Asus...still crash.
