I have an Asus N751JX. Miracast worked fine with the original wifi chip, a Atheros Qualcomm Wifi and Bluetooth card. But the performance of this card was not optimal, so i decided to remplace it by an Intel Wireless AC-7260, compatible WiDi.
Performance are better, but miracast doesn't work anymore.
My laptop see my tv, my tv detect thnt the laptop try to connect, but after a few time, my laptop declare there is no response from my tv, and stop trying to connect.
I install Asus drivers, then newest drivers from intel, the same : does'nt work.
So, with no solutions, if i want to have miracast again, i must return on my old Wifi card.
(i originaly posted on widi topics, but it seems to have vanish).
We would like to inform that Intel® WiDi and Intel® Pro WiDi have been discontinued and support for these is no longer available. The Wireless display forums have been removed as well. For more information, please check the following advisory:
http://www.intel.com/content/www/us/en/support/emerging-technologies/000021693.html Product Discontinuation Notice for Intel® WiDi and Intel® Pro WiDi
Keep in mind that custom integrations of wireless adapters are not supported by Intel since this may lead to installation errors, connection issues, software error messages, and in some cases it may even be illegal.
Intel does not recommend end users install or upgrade the various Intel® Wireless Adapters; you should always contact the http://www.intel.com/content/www/us/en/support/topics/OEMs.html Computer Manufacturer or its authorized representative to check which adapters are supported by your PC and replace it with them whenever possible. In your specific case, the new wireless adapter may not be compatible with your system, or you may have missed steps during the replacement, causing Miracast* to stop working.

So, since PC exist, the base is the possibility to improve hardware by changing various parts and drivers, but now, it's nor more possible with intel ?
And, there's a topic on the community about the same model of laptop (Asus N751JX) with an original Intel AC 7260 wifi adapter. For me, it means this combination exists from the manufacturer (but maybe not fonctionnal for miracast....).
So i don't accept your answer, because it's just a way to not take responsability for a material sold with WiDi compliance (a norme created by Intel).
It's my fault, i should make more research before buying this card, because i found on this forums a lot of unresolved questions about this card.
I'll return on my Qualcomm wifi adapter.
Miracast* and Intel® WiDi are technologies that depend on the hardware of the computer, as well as the OS, drivers and other software components. We cannot assure that these components will interact properly in custom integrations.
Please engage Asus support, so they can let you know if the Intel® Dual Band Wireless-AC 7260 is supported in your PC, if it is, they will be able to provide the correct method to remove any software related to the old adapter before installing a replacement. Again, keep in mind that WiDi reached End of Interactive Support, and now this functionality is ruled by Miracast* standards and the built-in features of Windows* OS.
