hi guys
i have dell 5110 and windows 8 64 bit
my bluetooth driver is "Qualcomm Atheros AR3011 Bluetooth 3.0"
in device manager this driver does not install and has a yellow eror near it
i tried everything like driver pack solution , download a driver by the same name for windows 8 64 bit but non of them work
please help me my friends?

goto device manager,

find your bluetooth device

uninstall it

on top click action

click scan for hardware changes

wait for it to reload

is it still with a yellow hazard?

do you have this version of drivers 1.0.3.0 ?

These are driver files, extract the CAB files into a folder (with winrar or 7zip) and when you update drivers from the device manager select manually select and point to the folder where you extracted the files..
