Miracast keeps disconnecting

[Paul_Watson]

The laptop keeps randomly disconnecting from miracast.  The wifi connection to my router keeps running seamlessly but the miracast connection is lost and I have to restart it.

How Do I Find My Model Number or Product Number?

I grasp that your Miracast continaully disconnects but your wireless connection it unaffected. Miracast uses a Wi-Fi direct  link for the connection and does not use the network router.  Theoretically you could turn the router off and the Miracast should work.

Have you done all your Windows updates?

Have you ran the Windows troubleshooter?

 Have you ran the  HP Support Assistant  to aid with HP updates and troubleshooting?

Here is a link to Project to a wireless display with Miracast (from windowsitpro) that may help.

If you have a firewall running have you tried adding the Miracast connection to the white list?

If you disable the firewall temporarily do you have the same issue?

Thanks - I tried all those but with no luck.  However, it seems to run fine when I'm watching something on BBC iPlayer but continually disconnects when I watch BT Sport, which I believe uses Silverlight.  Could this be significant?

Hi @Paul_Watson,

Thank you for the update. 

Yes that could be important.  Is there any updates for Silverlight available? When it disconnects is it just the program your watching that stops or does the display itself disconnect.

If it is just the program it could be the web site.

Have you checked for viruses and malware which could affect your performance?  MS Malicious Software Removal Tool

I hope this helps!

Thanks.  The display itself disconnects.

I've done all the latest updates for Silverlight.

The malicious software removal tool found nothing.

I'm running Avast and Malwarebytes.  They also report no problems.

Hi @Paul_Watson,

Thank you for the update.

As this appears to only happen when using Silverlight, have you tried using a different browser with it?

Here is a link to Frequently asked questions about Silverlight  which will help with support options for you to explore.

This link will provide the  browser that support it.  Click on 'system requirements"

Microsoft Silverlight

Hope this  helps!

[Paul_Watson]

I'll try it on different browsers and let you know
