How to Fix Bluetooth Not Working in Windows
Bluetooth on your Windows computer has stopped working. The Bluetooth toggle is missing from Settings, Bluetooth will not turn on, your computer cannot find nearby devices, or previously paired devices no longer connect. Bluetooth problems in Windows usually come down to drivers, services, or adapter issues — and they follow a logical troubleshooting path from simplest to most involved.
Check if Bluetooth is turned on
Before troubleshooting, verify Bluetooth is actually enabled:
- Quick Settings: Click the network/volume/battery icon area in the taskbar (bottom-right). Look for a Bluetooth tile. If it is grayed out, click it to turn Bluetooth on. If the Bluetooth tile is missing entirely, the Bluetooth adapter may be disabled or not installed
- Settings: Open Settings, Bluetooth and Devices. The Bluetooth toggle should be at the top. If the toggle is missing, Windows does not detect a Bluetooth adapter
- Airplane Mode: Check that Airplane Mode is off. Airplane Mode disables all wireless radios including Bluetooth. Settings, Network and Internet, Airplane Mode — make sure it is off. Some laptops have a physical wireless switch or a keyboard function key (often Fn+F2 or similar) that toggles all wireless radios
Restart the Bluetooth adapter
Toggling the Bluetooth adapter off and on resets its state and often fixes connection issues:
- Open Settings, Bluetooth and Devices
- Turn the Bluetooth toggle Off
- Wait 10 seconds
- Turn it back On
If the toggle is unresponsive or stuck, try disabling and re-enabling the adapter in Device Manager:
- Right-click Start, Device Manager
- Expand Bluetooth
- Right-click your Bluetooth adapter (usually named Intel Wireless Bluetooth, Realtek Bluetooth, Qualcomm Atheros, or similar)
- Select Disable Device, confirm
- Wait 10 seconds, right-click again, Enable Device
Run the Bluetooth troubleshooter
Windows has a built-in Bluetooth troubleshooter that checks common issues automatically:
- Open Settings, System, Troubleshoot, Other Troubleshooters
- Find Bluetooth and click Run
- Follow the prompts. The troubleshooter checks the Bluetooth radio, driver, and service status and attempts to fix any issues it finds
Check the Bluetooth service
The Bluetooth Support Service must be running for Bluetooth to function. If this service has stopped or is not set to start automatically, Bluetooth will not work:
- Press Windows+R, type services.msc, press Enter
- Find Bluetooth Support Service in the list
- Check that Status is Running and Startup Type is Automatic
- If it is stopped, right-click and select Start
- If it will not start, right-click, Properties, set Startup Type to Automatic, click Apply, then click Start
Also check Bluetooth User Support Service if it exists — this service handles Bluetooth audio and file transfer in Windows 10 and 11.
Update the Bluetooth driver
An outdated or corrupted Bluetooth driver is one of the most common causes of Bluetooth problems, especially after a Windows update:
- Open Device Manager, expand Bluetooth
- Right-click your Bluetooth adapter, select Update Driver
- Select Search Automatically for Drivers
If Windows does not find a newer driver, download the latest Bluetooth driver directly from your computer manufacturer's website (for laptops) or from the Bluetooth adapter manufacturer (Intel, Realtek, Qualcomm). The manufacturer's driver is almost always newer than what Windows Update provides.
Reinstall the driver
If updating does not help, a clean reinstall removes any corrupted driver files:
- In Device Manager, right-click the Bluetooth adapter
- Select Uninstall Device. Check the box for Attempt to Remove the Driver if available
- Restart the computer. Windows will reinstall a basic Bluetooth driver automatically
- After restarting, check if Bluetooth works. If it does, optionally install the manufacturer's full driver for the best performance
Check for hidden or disabled adapters
The Bluetooth adapter may be present but hidden or disabled:
- In Device Manager, click View, Show Hidden Devices
- Look under Bluetooth for any grayed-out or down-arrow entries (disabled devices). Right-click and Enable Device
- Also check under Network Adapters — some Bluetooth adapters appear here instead of under the Bluetooth category
- Look for entries with a yellow warning triangle — these indicate driver errors. Right-click, Properties, and read the error in the Device Status box
USB Bluetooth adapter checks
If your computer uses a USB Bluetooth adapter (a small dongle plugged into a USB port):
- Try a different USB port: USB ports can fail individually. Move the adapter to a different port, preferably a USB 2.0 port on the rear of a desktop (USB 3.0 ports can cause interference with Bluetooth signals due to the 2.4 GHz noise they generate)
- Check USB power management: Windows may be powering down the USB port to save energy. In Device Manager, expand Universal Serial Bus Controllers, right-click each USB Root Hub, Properties, Power Management tab, uncheck Allow the Computer to Turn Off This Device to Save Power
- Replace the adapter: USB Bluetooth dongles are inexpensive and can fail. If the adapter is not recognized in Device Manager at all (not even as an unknown device), it may have died. Try a different adapter
Intel Bluetooth specific fixes
Intel Bluetooth adapters (the most common in laptops) have specific known issues:
- Intel Driver and Support Assistant: Download and run the Intel Driver and Support Assistant from Intel's website. It detects your specific Intel hardware and provides the exact correct driver version
- Wi-Fi and Bluetooth combined adapter: Most Intel Bluetooth adapters share a physical card with the Wi-Fi adapter (Intel AX200, AX210, etc.). If both Wi-Fi and Bluetooth stop working simultaneously, the wireless card itself may have failed or become loose in its M.2 slot. Reseating the card (removing and reinstalling it in the laptop) can fix connection issues
- Firmware update: Intel Bluetooth adapters have firmware that is updated through driver packages. Using an outdated driver means outdated firmware, which can cause pairing failures with newer devices
Windows Update complications
Windows updates sometimes install incompatible Bluetooth drivers or change power management settings:
- If Bluetooth stopped working after a specific Windows update, check Windows Update history (Settings, Windows Update, Update History) to identify which update was installed
- You can roll back the Bluetooth driver to the previous version: Device Manager, right-click the Bluetooth adapter, Properties, Driver tab, Roll Back Driver. This option is only available if a previous driver version exists on the system
- If a specific Windows update broke Bluetooth and rolling back the driver does not help, you can uninstall the update: Settings, Windows Update, Update History, Uninstall Updates. Find the recent update and uninstall it, then pause updates until a fix is released
BIOS and hardware checks
- BIOS wireless setting: Some computers have a BIOS setting that enables or disables the wireless adapter (which includes Bluetooth on combo Wi-Fi/Bluetooth cards). Enter BIOS (restart and press F2 or Del) and check for a Wireless or Bluetooth setting under Advanced or Peripherals
- Physical wireless card: On desktops with a PCIe or USB Bluetooth adapter, check that the adapter is properly seated. On laptops, the wireless card is usually an M.2 module accessible through a panel on the bottom. If the card has worked loose from its slot, it will not function
