If your wireless screen mirroring fails, check the following:
①Check if the firewall is enabled. If yes, turn it off.
②Check if VPN is active. If yes, turn it off.
③Check if virtual network adapter is enabled. If yes, disable it.
④If you're connected to wired network and the scan bridge hotspot (but the IP is using wired network actually), switch to the the scan bridge hotspot.
Note:
For connecting the scan bridge hotspot, the QR code scan result should start with 192.168.
If the QR code scan result doesn't start with 192.168, switch to wired network first, then manually disconnect it and reconnect to the scan bridge's hotspot.
