you dont need to install 5 different drivers. you only need to install the correct driver from Acer's website for your particular model of laptop and operating system.
I'ts not that i havent installed the right one
its just that i have the driver now . but its always off .. like there is no radio discovery ... the function key is working for every other options .. and its not responding to the wireless ... tried with 3 older versions from the driver that works .. and still the same
