how can ı install bluethoot driver on windows 11?

You are updating from the wrong places

Win11 by default only installs critical security updates, unless you made the mistake of selecting “Get latest updates” which includes drivers.

See your laptop/PC makers support to update both bios and ALL drivers.

There should be a shortcut to that makers update utility on your system.

Then set Bios to defaults & Pwr to balanced. At the end of the day shutdown, do not leave in sleep.

Do NOT update from any other source inc Device Manager

You only need to set the Advanced options for notify & Time, then leave win update to do its own thing.

If a self-build drivers/bios update via the mobo makers support site + any vid card site

Dear Canberk ALTINTAŞ!

Welcome to the Microsoft Community!

If you can't see Bluetooth or it doesn't work on Windows 11, you can try the following steps to install or update the Bluetooth driver:

1. Make sure Bluetooth is on:

On laptops, there is usually a physical button or key combination (such as Fn + F5) to turn Bluetooth on or off. Confirm that the Bluetooth switch is on.

2. Go to Device Manager:

Right-click the Start button and select Device Manager.

In Device Manager, expand the Bluetooth or Network adapters section and see if there is a Bluetooth device listed.

3. Update the driver:

If the Bluetooth device is listed but has a yellow warning sign next to it, there is a problem with the driver. Right-click the device and select Update Driver.

If the Bluetooth device is not listed, you can try to add it manually using the Add Legacy Hardware wizard, select Install the hardware that I manually select from a list (Advanced) and then select Bluetooth.

4. Use a downloaded driver:

If you have already downloaded the latest Intel Bluetooth driver, select Browse my computer for driver software in the Update Driver window.

Navigate to the location where you downloaded the driver, select the folder, and let Windows install the driver.

5. Use Windows Update:

Sometimes, Windows Update can automatically resolve driver issues. Go to Settings > Update & Security > Windows Update, click Check for Updates, and install any available updates.

6. Reset the Bluetooth module:

If none of the above steps work, you can try resetting the Bluetooth module. This usually requires going into the BIOS/UEFI settings, finding the Bluetooth settings, and resetting them to their default state.

7. Contact manufacturer support:

If the problem persists, you may need to contact Lenovo or other PC manufacturer's customer support to get drivers and help for your specific model.

8. Use a USB Bluetooth adapter as an alternative:

Using a USB Bluetooth adapter can also normally replace the built-in Bluetooth module, but no additional driver is required to use Bluetooth directly.

Note that some older hardware may not support Windows 11 or require specific drivers to work properly with Windows 11. If you have older hardware, make sure it is compatible with Windows 11.

I sincerely hope that the above troubleshooting steps and related information can help you. If you have any questions, please feel free to post in this thread. Although our responses are not real-time, I will be happy to work with you to resolve the problem if we have more information and further progress in troubleshooting.

Thank you for your understanding and support! 

I wish you all the best.
