Hello evrybody! My lenovoG580 mainboard was failed with a power shortage problem and some of its elements burned . After replacment the mainboard ( I bought a stock mainboard ) , I reinstall the os , drivers and other programs and everything is alright but wifi icon has a red X mark and dont work , Also Fn+F5 or Win+X can not enable that wifi and the drivers is 100% ok and the is not any yellow sign in device manager.My half min pci e wireless is Atheros ar5b195. I replaced it with 3 other mini wifi all was the same model and brand and reinstall the driver again but after installing there is that red X mark again.Is it true that the mini pci e wifi card must be registered in the mainboard's bios?so I must edit some codes in the wifi card or in the new mainboard bios? For now I use an extelnal mini wifi usb adapter to connect to the network but I like to know the reason of this problem.Thank you in advanced.
