First, confirm whether Bluetooth is enabled, check the status of Bluetooth switches in keyboard shortcuts, flight mode and settings; 2. Run the built-in Bluetooth troubleshooting tool in Windows 11 to automatically repair common problems; 3. Make sure that key services such as Bluetooth Support Service are started and set to automatic in service management; 4. Update, manually download or uninstall the Bluetooth driver to solve the driver problem through the Device Manager; 5. Delete the pairing record of the failed device and re-pair it to ensure that the device is in pairing mode; 6. Check Windows updates and install the latest patches including optional driver updates; 7. Finally, you can try running a command prompt as an administrator and execute the net stop bthserv and net start bthserv commands to reset the Bluetooth service. If there is still no Bluetooth option, you need to check hardware support or BIOS settings. The above steps can basically solve the Windows 11 Bluetooth connection problem.

Bluetooth connectivity issues with Windows 11 are indeed quite common, especially after the system is updated or when the device is replaced. If you find that Bluetooth cannot be turned on, the device cannot be connected, the device cannot be searched, or the connection is frequently disconnected after connecting, don't worry, the following methods can basically solve most situations.

1. Check whether Bluetooth is enabled and turn on the hardware switch

First, make sure that your computer's Bluetooth function is enabled:

• Keyboard shortcuts : Many laptops have Fn Fx (such as F2 and F3) to turn on/off wireless or Bluetooth, and check whether it is turned off by mistake.
• Flight Mode : Make sure Flight Mode is not turned on (Settings → Network and Internet → Flight Mode).
• Bluetooth switch : Enter "Settings" → "Bluetooth and Other Devices" to confirm that the Bluetooth switch is "on".

Sometimes the Bluetooth switch is gray and cannot be clicked, which usually indicates that there is something wrong with the driver or service.

2. Run Bluetooth troubleshooting

Windows 11 comes with troubleshooting to automatically detect FAQs:

1. Open "Settings" → "System" → "Troubleshooting" → "Other Troubleshooting"
2. Find "Bluetooth", click "Run"
3. Follow the prompts and the system will try to fix the problem

This tool can solve many problems caused by the service not being started or configuration errors.

3. Restart Bluetooth Support Service

Bluetooth relies on several critical services, and if they are not running, Bluetooth will fail.

Press Win R , enter services.msc , find the following services, and check the status one by one:

• Bluetooth Support Service
• Bluetooth Handsfree Service (if any)
• Device Association Service

Right-click → Properties → Startup type is set to "Auto", and then click the "Start" button.

A common problem is that the Bluetooth Support Service is disabled or failed to start.

4. Update or reinstall Bluetooth driver

Driver issues are the number one reason why Bluetooth is not working.

Method 1: Update through the Device Manager

1. Right-click the "Start" menu → "Device Manager"
2. Expand "Bluetooth" and right-click your Bluetooth adapter (such as Intel Wireless Bluetooth, Realtek Bluetooth, Broadcom, etc.)
3. Select "Update Driver" → "Automatically search for drivers"

Method 2: Manually download the latest driver

Go to the official website of the computer brand (such as Dell, HP, Lenovo) or the motherboard manufacturer website, enter the model to download the latest Bluetooth/wireless driver (usually Bluetooth and Wi-Fi are the same module).

Note: Do not only update the "Bluetooth Driver". It is recommended to update the entire wireless combination driver (for example, the Intel Wi-Fi 6 AX200 driver package includes Bluetooth support).

Method 3: Reinstall after uninstall

Right-click Bluetooth device → "Uninstall device" → check "Delete driver for this device" → restart the computer, and the system will automatically reinstall the driver.

5. Delete the pairing record and re-pair it

Sometimes old pairing information conflicts can cause connection failure:

1. Go to "Settings" → "Bluetooth and Other Devices"
2. Click on the question device → "Delete device"
3. Restart Bluetooth, search and match

For headphones, mouse and other devices, it is recommended to enter the "pairing mode" on the device side (for example, press the power button for 5 seconds long).

6. Check for Windows Updates

Microsoft often fixes Bluetooth compatibility issues through system updates:

• Go to "Settings" → "Windows Update" → "Check for Updates"
• Install all optional updates (especially "Driver Update" or "Optional Update")

7. Ultimate attempt: Reset Bluetooth module

If none of the above works, you can try resetting the system Bluetooth component:

1. Open Command Prompt as administrator
2. Execute the following commands in turn:

 net stop bthserv
net start bthserv

Or more thoroughly:

 net stop bthserv
net start bthserv
ipconfig /flushdns

This refreshes Bluetooth service and network cache.

Basically that's it. Most Bluetooth problems can be solved by updating the driver, restarting the service, or running troubleshooting. If your computer does not have Bluetooth options at all, it may be that the hardware does not support it, or it is disabled in the BIOS (come into the BIOS to check the wireless settings). Not complicated, but it is easy to ignore details.
