• 🔒 Firewall: temporarily disable Windows Defender or add an exception for the broadcast application.
• 🔄 Drivers: Update your Wi-Fi adapter driver via device Manager or the manufacturer's website (Intel, Qualcomm).

Typical errors and solutions:

Error	Cause	Solution
The device does not support Miracast	Old Wi-Fi adapter or driver	Please update your driver or use an external adapter (eg. TP-Link Archer T4U)
Failed to connect to the device	IP address conflict on the network	Reboot your router or assign a static IP to your TV.
No sound during broadcast	The wrong input is selected on the TV.	In your laptop's sound settings, select the TV as the output device.
