Please note some Intel® wireless adapters are supported in Windows* 8.1 but do not have a compatible driver yet; those adapters are using a Microsoft* inbox driver for the moment and therefore they may or may not work with Intel® WiDi or Miracast*. It is recommended to wait for the compatible Intel® wireless drivers to be released for better functionality. I apologize for the inconvenience.
