Windows 10: Connect to a wireless display disappeared after upgrading wireless network adapter to Intel...

After reading about a dozen articles and compiling all the requirements for Miracast, I finally figured out the settings change required for the Intel AC-9260 wireless adapter. Apparently Miracast requires both the 2.4GHz capability and the 801.11 a,b,g,n capability.

In the AC-9260 Adapter Configuration, there is an Advanced Setting named 802.11 n,ac Wireless Mode. It must be set to either Disabled or 802.11n. It cannot be set to 802.11ac.

And kudos to Microsoft folks. Changing the setting instantly updates all associated control panel and settings and made it relatively painless to exercise the changes and detemine the proper settings, without multiple reboots.

Windows Wireless Display Adapter-not connecting anymore

Hello Phillip,

Did you notice any changes on your PC prior to the issue? I suggest that you follow the steps outlined in this support article:
Troubleshooting Wireless Display Adapters.

Since updating drivers did not work, in addition, you can try to reset the Wireless Adapter.

1. On the adapter, press and hold the reset button for 10 seconds.
2. When the message " Ready to connect "shows, open the
   Action Center.
3. Select Connect, and in the list of displays, select
   Microsoft Wireless Display Adapter.

Please respond to this thread to let me know how the issue progresses. Similarly, if you have more questions, please inform me by replying to this post.

 

Wireless network adapter disappearing?

Hi, I've had an Asus Q400A for about 4 years now. A few months ago, it started doing this thing where I'll be working online, and suddenly I'll lose wifi connection. Then the wifi bars at the bottom of the screen have a yellow exclamation mark on
them, and then a few seconds later it turns into the Ethernet sign with a red x on it. My wireless adapter disappears completely. If I go to my device manager, all that is listed under my network adapters is the "Qualcomm Atheros AR8151 PCI-E Gigabit Ethernet
Controller (NDIS 6.30)." I am missing my "Intell Centrino Wireless-N 2230" wireless network adapter. It's like my computer's wifi is completely disabled, and I am only able to connect to the internet via Ethernet. Sometimes I am able to fix it with the troubleshooter
before the adapter shuts off completely and disappears, as it always turns yellow with the exclamation mark for a few seconds before disappearing. If I am fast enough I can run the troubleshooter and it will reset the wireless network adapter before it disappears.
But when this doesn't work or I am too late, not even restarting or shutting down my computer will bring it back. It just kind of comes back on its own after I let my computer sit turned off for a few hours. This is INCREDIBLY annoying, as I am a busy high
school senior, and most of my school work and internship work is done on my computer. I have tried reinstalling the intell wireless adapter driver, and that did not work. What should I do? Is this a hardware problem? I have an Asus Q400A notebook running Windows
10. I have also tried turning off the option for the computer to turn off the adapter to save battery and that did not work.

 

Microsoft Wireless Display Adapter connection issues

Hi,

Thank you for posting your query in Microsoft Community.

I understand your concern, however I suggest you to follow the steps below and check if it helps.

• 
  Press Windows Logo + X.
  
• 
  Go to Device Manager on your Surface Pro 3.
  
• 
  Go to Display Adapters.
  
• 
  Search for Intel (HD) graphics driver.
  
• 
  Uninstall this graphics driver and reboot your Surface Pro 3.
  

After reboot, an updated Intel (HD) graphics driver should be installed. And this driver might be capable to connect to Microsoft’s Wireless Display Adapter.
