8260 wireless adapter - Miracast freezes and sometimes randomly slows down net speed below 1mbps

  • When I'm casting my screen onto my TV, my wifi connection speed on the tablet I use slows down to between 50-60mbps from 400, however, the real problem is that it frequently drops below 1 or even to 0 for minutes at a time, making it impossible to browse the web and miracast at the same time.
  • I'm regularly disconnected from my router when using miracast.
  • The connection between my tablet and TV randomly freezes in a strange way, everything on screen becomes unresponsive and I also don't get any sound when this happens, however, the pointer does not freeze, so I'm definitely not disconnected.
  • Sometimes small parts of my screen turn pink indicating data loss.



I don't necessarily experience these things at the same time, for all I know, they could even be unrelated.



Things that I've tried so far:

-Updating my wireless adapter driver.

-Updating my bios (just to be sure)

-Turning off RSC

-Disabling power saving for my adapter

-Checking the wireless connection log. There were no errors recorded whatsoever. 


I also tested it with another laptop that has an 8265 adapter, and I got similar results. Managed to reproduce 2/4 problems in a brief amount of time (the internet slowdown and pink patches on the screen).

Contact Microsoft regarding Miracast support.

I did contact them but they are yet to find out what's causing it. It goes without saying that an OS is necessary for using an adapter so I don't think it's a stretch to ask for help from the adapter's manufacturer regardless of what's causing it. It's also plenty possible that the problem's with the driver.

Hello ABogn1,


Thank you for posting on the Intel® communities.


I was checking this thread and I would like to mention that the information provided by Al.Hill is correct.


It is worth mentioning that Miracast* is no longer supported and support should be addressed to your Original Equipment Manufacturer (OEM, PC-laptop manufacturer) or Microsoft® support, and in the case that a driver issue would be found, the OEM/Microsoft will determine root cause and work internally with Intel.


For more information, please refer to Using Miracast* with Windows 8.1* and Windows® 10



We will proceed to close this inquiry.
