I am unable to see Miracast (AirServer) as a destination to mirror to

When dealing with wireless technology, there are a number of circumstances that can block the signal. If the casting button does not appear, your computer does not show up on the list of destinations, or nothing appears on your computer after selecting it from the destination list, then your device is not able to communicate with AirServer for one of a few possible reasons.

The first thing you should try is powering off and restarting your device(s), computer(s), and router. Make sure your device and computer are on the same network.

Your router might be running old firmware. Visit the router manufacturer’s website and download / install the latest firmware. Please also make sure that Bonjour/mDNS and multicast are enabled in your router's settings.

Try switching off the protocols which you are not using and restart the app. For example: if you are only using AirPlay, switch off Miracast and Google Cast.

For AirPlay/Google Cast specific discovery issues, try switching off AirPlay/Google Cast, waiting 10 seconds, and switching it back on.

If that does not solve your issue, run all available Windows updates on your computer. Your device(s) should also be updated with the latest software updates. If you are using Windows 10, we highly recommend using at least build 1809 for the best results.

Connection issues are most often caused by firewall software. You may have to adjust your firewall settings to allow AirServer to receive incoming networking traffic. Also, ensure the same is done on any secondary firewalls your computer may have. In most cases, the problem is caused by the native Windows Security. You can learn how to configure it correctly in .

Another possible cause of your connection issue may be that your connection cannot handle the bandwidth required for streaming or mirroring. You can try connecting your computer to the network with an ethernet cable to see if the performance is better.

Please also make sure that your network is listed in Windows as a private network or that you do not have any restrictions for AirServer in place when using the Public network setting. More information on this can be found on the .

If you are still not able to connect, the issue may be with your router or network.

If your Wi-Fi router supports interface isolation or Wi-Fi isolation, make sure that these settings are turned off. These settings prevent wireless devices from communicating with each other. Refer to the documentation that came with your Wi-Fi router to access its settings and make sure your router has the latest firmware.

If you are behind a multi-subnet or Layer 3 network, as is common on larger networks and schools, please ensure that multi-casting is enabled and Bonjour is discoverable across the network. In most cases Bonjour will not be accessible across the network, as it's blocked by default, however, there is you can look over or send to your networking Administrator to look over regarding Bonjour across Layer 3 Networks and Multiple Subnets.
