I just purchased and installed an Intel Dual Band Wireless AC-7260 adapter for my desktop with the intent to use the Miracast feature in Windows 8.1. I've installed and uninstalled the latest Win 8.1 drivers many times, when i run dxdiag it continually outputs "Miracast: not supported by wifi driver". I've gone through all the community advice and haven't had any luck. I don't have any firewalls or vpn adapters. Suggestions?
