Hi, I had the same problem after installing update 1511, so I tried to reinstall the driver with DoubleDriver. The installation went fine, but WiFi still didn’t work. I then rebooted, opened Device Manager and uninstalled the Broadcom board (when asked if I wanted to remove driver too I confirmed I wanted to remove it). After another reboot, WiFi started working again.
Now I have the rotation problem: sometimes it works, sometimes it doesn’t.
