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 can inspect the relevant local evidence and propose a fix plan for review.
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.
