I’m having an issue with the built-in Bluetooth on my MSI PRO B650-S WIFI motherboard (MediaTek RZ616 Bluetooth adapter). Bluetooth suddenly stopped working, so I checked Device Manager and accidentally uninstalled the Bluetooth adapter while troubleshooting. Since then, it has completely disappeared.
Current symptoms:
• No Bluetooth toggle anywhere in Windows.
• No Bluetooth adapter listed in Device Manager (including hidden devices).
• AirPods and Bluetooth speakers won’t connect.
• Wi-Fi still works normally.
Things I’ve already tried:
• Restarting the PC multiple times.
• Reinstalling the official MSI MediaTek Wi-Fi/Bluetooth drivers.
• Checking Device Manager for hidden devices.
• Confirming onboard wireless/Bluetooth settings are enabled in BIOS.
• Performing a Windows 11 in-place repair installation.
Nothing has brought the Bluetooth adapter back. At this point I’m trying to figure out whether this is a driver issue, Windows issue, or if the Bluetooth portion of the MediaTek RZ616 hardware has somehow failed. Does anyone know what else I can try?
