When you are unable to discover AirServer using Miracast (used by Windows 10 and Samsung devices), there can be a number of possible causes.
- Another software such as Microsoft's "Connect" app, is currently using resources that are needed by AirServer's Miracast functionality.
- Your computer does not have a Wi-Fi Adapter or a Wi-Fi adapter that is compatible with Miracast. This is a requirement in order to use Miracast as this screen mirroring protocol is built on Wi-Fi Direct.
Miracast mirroring requires a Miracast-compatible graphics adapter/card and a Wi-Fi adapter/card with, at least, NDIS 6.3 drivers on both the receiving and transmitting devices.
If you are unsure about this, you can check whether or not your computer running AirServer supports Miracast by following these steps:
- Open up a Command Prompt window
- Write "netsh wlan show driver" and press ENTER
- The command prompt will show you whether or not your device is Miracast compatible
If the command prompt displays the "The Wireless AutoConfig Service (wlansvc) is not running."-error, you can try to enable to. Instructions can be found in a dedicated support article.
To check if you are using the correct NDIS drivers, please follow these steps:
- Open Powershell and type “Get-NetAdapter | Select Name, NdisVersion”.
- The output will show NDIS versions that need to be 6.3 or higher for the Wi-Fi adapter.
- Make sure you are using at least Windows 10 build 1709 or higher (using at least build 1809 is recommend as this introduces Miracast PIN support).
- Try removing AirServer from the cached list of receivers in Windows on the sending device. This can be done by following the steps below:
- Press Windows Key + K.
- Choose "Find other types of devices" at the bottom of the sidebar that appeared.
- Find the AirServer which does not work in the list of "Wireless displays & docks".
- Click it and choose "Remove device".
- Try to connect again.
- Turn off any other software that you suspect is using Miracast such as Microsoft's "Connect" application, then restart AirServer. If the error message is still being displayed after restarting AirServer, go ahead and restart your computer and start AirServer again.
- Download and install/re-install the latest driver updates for your Wi-Fi adapter then restart the computer.
