Hello, may I ask for the operating system you are using? Is it 64-bit?
These are some versions you can try: 15.8, 16.1.1, 16.7. The version 16.11.0 only provides 64-bit driver for your Intel® wireless adapter.
I'm using 64 bit Windows 8 Pro. I have been playing back and forth and it seems the reconnect is much faster now, although I'm still showing driver version 15.11. However, I have a new issue. As soon as I run the install to either uninstall or repair the driver, I'm getting a message that the access to a specific registry path is denied. This may have something to do with the changes in Admin privileges, as I had also updated bluetooth drivers yesterday, which required me to add access to a bluetooth entries in the registry.
While I am not aware of such changes in the registry or if they made your Bluetooth work, there are a few things that you might want to try, if you choose to.
