Bluetooth Driver Error in Device Manager – Fix
Yellow exclamation mark on your Bluetooth radio? This means the "Bluetooth Support Service" has failed or the driver handshake is broken. Againly fixes this automatically by re-starting the wireless stack and clearing the cached device pairings.
Why this happens
- Service Mismatch: The "Bluetooth User Support Service" is set to Manual instead of Automatic.
- Radio Interference: Too many 2.4GHz devices are confusing the Bluetooth controller.
- Update Regression: A Windows Update replaced your Intel/Qualcomm Bluetooth driver with a version that doesn't support BLE (Low Energy).
Fix it manually
- Restart Services: Win+R >
services.msc> Find "Bluetooth Support Service" > Right click > Restart. - Uninstall and Cycle: Uninstall the Bluetooth device in Device Manager, then toggle airplane mode on and off.
- Turn Off Power Management: Uncheck "Allow the computer to turn off this device" for your Bluetooth radio.
