Now when I try to install it by doing to device manager, update driver and then browse my computer for update, when I go next it again says I have the latest update already installed and wont let me install the mentioned driver from the folder

The one you are mentioning is a Bluetooth update. Will it fix my wifi problems as well with that one update?

The one u mentioned is a Bluetooth driver update and I have issues with Wifi... will downloading it work for both?
