Wifi driver windows 10 can not be installed

I have a dell vostro 3560. Recently I upgraded to windows 10. I tried to install drivers but had no success with wifi driver. I installed the file butwhen I go to device manager it still shows that the driver is the original one which windows had installed:

Broadcom 802.11n Network Adapter

I even tried to uninstall this driver and delete driver files and restart windows but no success.
