PLEASE READ MY PROBLEM FULLY!!!

 

Hi all,

 

I have an acer aspire 4750g i7 8gb 640gb geforce 540m 1gb laptop and been using it with the preloaded win7 home premium till yesterday and wanted to do a clean install of win 7, so downloaded a win 7 home premium iso burned it to a dvd, formatted my hdd and installed win7, activated it and all went good. I downloaded all the latest drivers from acer support site and installed them all and now i find my wifi not working at all. i updated my bios before and thought that must have created the problem so tried downgrading the bios with all the available versions but no success with the wifi. The strange thing is i can see that my wifi starts working from the welcome screen untill the windows boots fully into desktop after which the adapter shuts itself off. The Atheros CCX diagnostic utility confirms that when the desktop is visible and windows still loading the adapted works but after few seconds windows fully loads and the wifi adapter shuts off. I tried to use windows mobility center but the "turn wireless on" option is greyed out. Network diagnostics return that "wireless capability is turned off" and asks me to turn it on but i don't understand how to turn it on, I tried the fn+F3 combination keys but it shows as the adapter is on but the adapter is not really on Smiley Frustrated
