Miracast Windows 11 issues

[OSSMAPhil]

Hi All,

We have Microsoft Wireless Display adapters (4 square logo) in all our teaching spaces in school.

Staff use Surface Pro 9 to connect. This Summer we upgraded to Windows 11 ready for the end of Win 10 support.

It was not realised that the MS wireless display adapters do not support Win 11.

 

Since, we have tested different combinations.

We have identified that it is not the devices. There are no issues with Windows 10.

Windows 11 surfaces will not cast to the MS adapters or the built-in screen sharing on the TVs in the classrooms.

 

Therefore, we believe there is an issue with Windows 11 and miracast, but cannot find anything online.

MS have just said that there are no known issues.

 

We have not got any other mobile devices to test with. Using an android phone, it connects to all methods without issues.

 

Has anyone else had any experience with Windows 11 and Miracast?

We’ve used the various models of MS Miracast adapters for years, with Windows 11 since it came out. We’ve been 100% Windows 11 for over a year with no issues connecting to these devices. Science classrooms are fully wireless and only connect to projectors via these adapters, all other classrooms are both HDMI and wireless, again no issues.

@OSSMAPhil did you ever resolve this problem? We've hit the same issue.

Hi,

Just we still have issues. It does seem that if you persist and keep trying to connected after 5-6 times it will connect.

It also seems to be if the device is in the same room as the adapter for a day, it seems to work the next day and once previously connected, seems fine.

 

Then if staff move around we get issues for a few days until it settles.

 

It doesn't seem to be just windows 11 now, with some windows 10 laptops also experiencing the same.

The adapter shows the user name of the logged on user and says "user is connecting" and then says couldn't connect. So its not an issue with not broadcasting, just seems to be if its a new wireless device that it doesn't know.

Thanks for the update. Our Windows 11 devices flat out refuse to connect while Windows 10 on the same device always works.

we have even tried some models of the j5Create devices, but its the same experience.

 

Using the built-in miracast on the TVs seems to be better, but they don't stay on cast source when turned off. At least the MS adapters connected to HDMI port, when the TV is power cycled they come back to the same source and show the Win + K.

Getting teachers to learn a new way to connect and find the remote for all rooms will be a bigger issue.

Just like you describe, the adapter shows the user name of the logged on user and says "user is connecting" and then says couldn't connect. But despite many many repeated attempts we never get a successful connection.

 

I've also got a j5create adaptor sat on my desk too - Windows 11 refuses to connect.

Well happy friday - I've just got this working having found this article https://screenbeam.my.site.com/support/s/article/Preparing-Domain-Group-Policy-Settings-for-Windows-Miracast-over-Wi-Fi-Direct

 

- Create a Firewall rule to allow all ports/protocols for %systemroot%\system32\WUDFHost.exe on the Public Profile

- Ensure "Computer Configuration > Admin Templates > Network > DNS Client > Turn off multicast name resolution" is set to DISABLED

 

Hope this helps others
