We have received some reports from customers who are not being able to have the Wi-Fi or Bluetooth* connection working properly because Windows* Update Dynamic seems not to be working accurately upon installation, as it is supposed to uninstall the current wireless or Bluetooth* driver installed before upgrading to Windows* 10. The OS upgrading process tries to find the latest inbox driver in Windows* Data Base; but the process is not being completed successfully. We would like to inform you that there is a new driver release available in our download center and comes with several fixes for the situation previously mentioned.
Intel® PROSet/Wireless Software for Windows® 10
Intel® PROSet/Wireless Software for Bluetooth® Technology for Windows® 10 64-bit (WP)
Intel® PROSet/Wireless Software for Bluetooth® Technology for Windows 10® 32-bit (WP)
If you need to get an specific driver version, you can get in contact with your http://www.intel.com/support/oems.htm Computer Manufacturer Support and ask for the most recent driver for your system once it is upgraded to Windows* 10.
