Possible Causes of Bluetooth Performance Issues

1. Bluetooth Interference
   Wireless signals in the 2.4 GHz band are susceptible to interference from Wi-Fi networks, other Bluetooth devices, and household electronics, leading to disrupted connections and degraded audio quality.

2. Driver and Firmware Compatibility
   Outdated or incompatible Bluetooth drivers and firmware can cause stability issues. Ensuring all drivers are current is essential.

3. Power Management Settings
   Power-saving features implemented by Windows or the motherboard may inadvertently throttle Bluetooth device performance, leading to lag and disconnections.

4. Hardware Limitations
   While modern motherboards generally provide robust Bluetooth capabilities, some onboard Bluetooth adapters may have lower signal strength or reliability, especially if they share bandwidth with other system components.

Recommended Solutions

1. Optimize Bluetooth Placement
2. Minimize physical obstructions between your PC and Bluetooth devices.

3. Reduce the number of active wireless devices operating on the same frequency.

4. Update Bluetooth Drivers and Firmware

5. Visit the motherboard manufacturer’s website to download the latest Bluetooth drivers.
6. Check for BIOS updates that may improve hardware compatibility.

7. Update the firmware of your Bluetooth headphones if available.

8. Adjust Power Settings

9. Navigate to Windows Power & Sleep Settings.
10. Access Additional Power Settings and select your active power plan.
11. Click on “Change plan settings” > “Change advanced power settings.”
