Bluetooth audio devices and wireless displays greatly enhance our productivity and entertainment experiences. However, many Windows 10 users encounter problems such as Bluetooth devices failing to connect, unstable connections, or wireless displays not working. Here's a guide to help you solve these issues.  

Common Problems and Their Causes

• Interference from sources like Wi-Fi or microwave ovens.  

• The system's Bluetooth service is not running properly.  

Wireless display cannot connect:

• The Miracast feature is not enabled or the hardware does not support it.  

• The display or graphics driver needs updating.
