How to Update Realtek Bluetooth Driver – Windows 11

The Bluetooth interface is used on Windows 11 (and Windows 10) systems to connect Bluetooth devices. Mobile phones, speakers, printers, or even another computer. Bluetooth wireless communication is ideal for short-range wireless communication. And like all hardware devices in Windows, the Bluetooth device needs a Bluetooth driver to function. The most common Bluetooth chips used in PCs are from Intel and Realtek.

If no driver is installed, Windows will not recognize the device, or Bluetooth will not function properly. So, if Bluetooth is not working in Windows 11, you might need to update the Bluetooth driver. In this article, we’ll show you how to update the Realtek Bluetooth driver. Of course, we also have instructions on updating the Intel Bluetooth driver.

Note: These instructions apply to both Windows 10 and Windows 11. It is important to update the Realtek Bluetooth driver on Windows 10 already, since the upgrade to a later Windows version can be blocked because of an old driver!

Windows 10 Update Problem Realtek Bluetooth

Updated Bluetooth drivers can solve this type of problem. Updated drivers will also make sure that any known bugs in previous versions are fixed, and performance and connectivity are maximized.

Automatically Update Drivers

Windows 10 and Windows 11 include support for a lot of devices by default. Drivers for the devices are either included in the Windows installation or retrieved during the Windows Update process.

If the Realtek Bluetooth driver needs to be updated, the first step is to run Windows Update. Also make sure that drivers updates are included in Windows Update, as automatic driver updates can be disabled in Windows!

Apart from Windows Update, a driver can also be updated from the Device Manager in Windows 11 directly.

Press the Windows + R keys to bring up the run dialog box.
Type devmgmt.msc in the Run field and press Enter or click the OK button.
In the Device Manager window, locate the device for which to update the driver. Right-click the device, and in the context menu select Update driver.
Next select the option to let Windows Search automatically for drivers.
Click the Close button when done.

For more details, also see installing driver updates using the Device Manager in Windows 11.

Another method to automatically update Windows drivers is to use the DriverFinder program. This software automatically scans all hardware devices in your PC and then recommends the appropriate device drivers for them. It will not just update the Realtek Bluetooth drivers, but allow you to update all your device drivers.

Manually Update the Realtek Bluetooth Driver

Manually updating drivers in Windows means downloading the driver installation files and running an installer or updating the driver from the Device Manager.

Driver files for Bluetooth devices can be available on the PC manufacturer’s website or the Realtek website. First, visit the support site of your PC manufacturer and check for updated drivers of your model. If they are not available, or still not the latest version, you can visit the Realtek website.

Realtek offers support for most of its devices online. This support includes the option to download Windows drivers for many of their devices.

Using the Realtek Support site

Open a web browser and navigate to the Realtek software download page.
On the Realtek web page, use the Product Line dropdown box to select Wireless Lan ICs.

Double-click the subfolder in the opened File Explorer
Now locate the setup.exe file in the subfolder and double-click it to execute the driver installation process. Follow the instructions on screen.

With the above instructions, you can download and install updated Realtek Bluetooth drivers for Windows. This should solve any issues you have with Realtek Bluetooth not working in Windows 11.

Lenovo Camera Driver for Windows 11

Using Windows 11 on a laptop can be great, assuming everything is working. And if you want to use your Lenovo laptop for video chat or video conferencing, you need the audio features and camera to be working. To make sure the Lenovo Integrated Camera is working, the right Lenovo camera driver needs to be installed.

Download and install the Lenovo camera driver

Since Lenovo uses different camera components in its laptops (Sonix, Realtek, and others), it is important to get the right driver for your device. The first place to look for the right Lenovo camera driver is the Lenovo support website.

Open an Internet browser and visit the Lenovo support website.
The website will automatically direct you to your local support site (region and language). If not, make sure to disable any VPN software you might be using.
On the webpage, click the SUPPORT menu and then click PC.
On the next page, enter the serial number or the model name of your Lenovo laptop and press Enter.

Tip: If you do not know either, you can use the Browse Product option, although that will also require you to know the model name/number.
Once you selected your product, you will see the Product Home page for your Lenovo laptop. Click the View Product Details link to show the extra options.
Next, click the Drivers and Software link.
On the Drivers & Software page, select the option Manual Update.
Then click the option Camera and Card Reader.
On the Camera and Card Reader page, click the downward pointing arrow to the right of the first entry of the Integrated Camera Driver for your Windows version.
Note: If no Windows 11 driver is available, try the Windows 10 driver since they are compatible. The entries in the list are sorted by date, newest on top, so you want the first entry for the newest Lenovo camera driver.
Now click the download icon next to the Integrated Camera driver to start the download.
Once the download completes, run the downloaded file to install the driver and follow the on-screen instructions.

Update the Lenovo Camera Driver from the Device Manager

If a camera device is already recognized by Windows 11, it will show up in the Device Manager. In that case, updating the integrated camera driver directly from within Windows 11 is also possible.

Press the Windows + R keys and type “devmgmt.msc” in the Run box. Press Enter to confirm, or click OK. This will start the Device Manager.
In the Device Manager, expand the category Cameras or Imaging devices.
Right-click the webcam device that is present, and then select Update driver in the popup menu.
Next, click the option Search automatically for drivers to let Windows 11 use the Microsoft update catalog for finding and updating the Lenovo camera driver.
Click the Close button and then close the Device Manager window.

If no new version of the integrated camera driver is found, Windows 11 will show a message stating that “The best drivers for your device are already installed”. Windows 11 depends on manufacturers providing the latest drivers for their devices to Microsoft for inclusion in the Update Catalog. Depending on the age of your laptop and support for Windows 11 for it, this method may or may not find an updated driver.

Using a Driver Update Program

As mentioned earlier in this article, Lenovo and other laptop manufacturers use third-party components for their integrated webcams. A common component these days is the Realtek webcam device, but other webcam components are also used. Sonix, Sunplus, and Ricoh are other common choices.

This means that if no camera driver for Windows 11 is available from Lenovo for your integrated camera, another manufacturer may have a driver available for Windows 11. The easiest way to find the right driver, in that case, is to use our driver finder program. The software will automatically scan for all devices on your computer, including webcams, and find any suitable driver for your device matching your Windows version.

If your Lenovo webcam is still not working, maybe this guide to solving webcam problems is of help.

Fix Video DXGKRNL Fatal Error in Windows

The DXGKRNL fatal error in Windows is a Blue Screen of Death error (or STOP error) that will halt the operating system. A critical error in the DirectX software system causes this error.

When this error occurs, you will see the BSOD with the error message. Depending on the Windows version, the system will halt, or Windows will try to recover by scanning for problems.

Cause of the DXGKRNL Fatal Error

As mentioned, the problem is related to the DirectX graphics system that is installed in Windows. DirectX is a library that enables software to interact with the PC’s video and audio hardware. It is mainly used by gaming software. DirectX has been part of Windows since XP (version 9.0) until Windows 11 (version 12).

DirectX allows software to use the multimedia accelerator features of your video and audio hardware for great performance. But to do this, DirectX operates at a high security level in the operating system. So, if something goes wrong, problems are serious for the operating system.

What can go wrong? Well, mainly device drivers and DirectX itself. DirectX uses objects and drivers that execute at kernel level, and it also interacts with devices through device drivers for the video and audio hardware. Any problem with the DirectX file or configuration, or a problem with the device drivers can cause the DXGKRNL fatal error.

Solving the DXGKRNL Fatal Error

There are two main solutions to fixing the error. The first is updating or reinstalling DirectX, and the second is updating or reinstalling the device drivers for video and audio hardware.

If you can still boot into Windows, you can execute the steps to solve the error. If Windows won’t start anymore, try using the Safe Mode boot. In that startup mode, Windows only uses a standard video driver with minimal features. For Windows 7 and Windows 8, the steps are different. Press F8 during boot to get into the Advanced Boot Options screen and select Safe Mode.

DirectX in Windows

With most software, you would simply say: uninstall it, reboot, and then reinstall it. That was possible for older versions of DirectX as well, but not in the latest Windows versions. DirectX is an integral part of Windows in the latest Windows versions.

For Windows 7 there was still a separate update that can be downloaded to install DirectX 11.1.

For later Windows versions, you simply need to make sure you run Windows Update.

In Windows 10, open Settings, select Update & Security and click Check for updates.

In Windows 11, open Settings, select Windows Update and click Check for updates.

DirectX Diagnosis

To check the version, and any potential problems, you can use the DirectX Diagnostic Tool. This tool is part of the DirectX installation and can be started by typing “dxdiag” in the Start menu search box.

After starting the dxdiag app, you will see the details of the DirectX installation.

With the System tab active, the DirectX Version can be seen at the bottom of the list with System Information.

Use the Next Page button to jump through the pages, or simply use the tab selectors to switch directly to the Display, Sound, or Input options.

In the Display tab, you can see which features are enabled. The Notes section will show any problems with the DirectX functionality. The Notes section is present for all tabs.

If a DirectX feature is Disabled, it might either disabled in the settings, not be supported by your PC hardware, or not supported due to driver limitations.

Update the Display Driver

If the DXGKRNL fatal error is caused by a device driver, the first step is to update the driver to the latest version. Updated drivers can have bug fixes, performance improvements, and feature enhancements.

To update the display driver in Windows, use the Device Manager.

Open the Device Manager using the search box in the Start menu, or press the Windows key + R and type devmgmt.msc in the Run box followed by the Enter key.
In the Device Manager, expand the Display adapters category by double-clicking it.
Next, right-click the listed graphics adapter, and in the popup menu, select Update driver.
Use the option Search automatically for drivers to let Windows check for graphics driver updates automatically. If you have downloaded the latest graphics driver for your computer manually, use the option Browse my computer for drivers and select the location.
Once the updated driver is installed, click Close and close the Device Manager.

Next, restart the computer and see if the problem is resolved.

Uninstall the Display Device to fix the DXGKRNL error

There may be no driver update available for the graphics card. Or an update is available, but the update did not fix the problem. In that case, the driver configuration may be a problem. Uninstalling the display device can then help solve the error.

Uninstalling a device and then restarting the PC will force Windows to reinstall the graphics device. If the driver was also deleted during uninstall, the driver will also be downloaded and installed again.

Use the instructions from the previous section to open the Device Manager and expand the Display adapters
Right-click the graphics adapter, and in the popup menu select Uninstall device.
In the Uninstall Device window that shows next, make sure to select the option Attempt to remove the driver for this device.
Note: for previous Windows versions this option is worded a little differently.
Click the Uninstall button to continue.

Once the device is uninstalled, restart Windows. The display device will be reinstalled during the restart with the latest driver.
Note: in case the display device is not automatically reinstalled, use the Scan for hardware changes in the Action menu of the Device Manager to force the device installation.

System Restore

None of the solutions so far working? If your Windows configuration is using System Protection, you can try the System Restore option to revert to an earlier, working configuration.

With every change, Windows can create a restore point that will help bring back a previous configuration. Here are the instructions for Windows 11.

Open Settings from the Start
Select System, and then About.
Scroll down to the Related links section, and then click Advanced system settings. This will bring up the System Properties.
In the System Properties window, select the System Protection
Next, click the System Restore button.
Click Next to show the list of restore points on your computer.
Select which restore point to use, and then click Next.
Click the Finish button to confirm the restore operation.
Click Yes in the confirmation window.

Windows will now create a restore point. Your PC may restart during the process. Just be patient and let the system restore complete.

After the final restart, see if the problem is solved.

Although this specific error is related to the display aspect, DirectX also uses sound and other media and input drivers. It is recommended to keep all device drivers up to date using DriverFinder.

Intel UHD Graphics 620

The Intel UHD Graphics 620 is a graphics solution from Intel for mobile computers. It is integrated into the 8^th generation Kaby Lake processors (or core U-series laptop processors). Since it is integrated into the processor chip, it does not come with its own memory but uses system RAM instead (up to 32 GB of shared memory can be used).

The main future of the Intel UHD graphics 620 processing unit is that it is a low-power solution (only uses 15W maximum). It supports DirectX 12, operates at 300 MHz frequency (can be boosted to up to 1000 MHz), and is an upgrade from the Intel HD 620 graphics solution. Full specs can be found at Intel.

Although usable for some gaming, the chip is not comparable to dedicated, external graphics solutions like the AMD and Nvidia graphics chips.

Intel UHD Graphics 620 Driver

To make sure the Intel UHD graphics 620 produces the best results, it is important to install the latest Intel drivers for it. Drivers are available for all Windows version from XP to Windows 11.

The right drivers will make sure the 4K resolution (at 60Hz) is supported and that DisplayPort 1. And HDMI 2.0 are properly working.

To get the latest driver for the Intel UHD 620 solution, download the latest version from the Intel support site. The file name will be something like gfx_win_xxx.xxxx_xxx.xxxx.exe, where each x represents a version number. The driver file for the Intel UHN graphics 620 solution supports all Intel 6^th – 12^th Generation core graphics processors.

When downloading the driver file, be aware that the file can be over 1 GB in size, so the download will take a moment to complete. Once complete, execute the downloaded file to begin the driver installation. After confirming the UAC dialog, the installation screen will show.

Click the Begin installation button and follow the instructions in the installer to complete the driver installation.

Updating the Intel UHD Graphics 620 Driver from the Device Manager

Instead of downloading the complete processor driver installation file from the Intel support website, you can also update the Intel graphics driver from the Device Manager in Windows.

Here is how:

Open the Device Manager by pressing the Windows key + R at the same time. Type devmgmt.msc in the Run dialog box, and press the OK button.
In the Device Manager, expand the Display adapters
Right-click the Intel UHD Graphics 620 device, and in the popup menu select Update driver.
Click the Search automatically for drivers option to let Windows find a newer driver for the graphics device.
Wait for the driver to be updated, and then click Close to finish the driver update process.

If no new driver is found, you will see a message showing “The best drivers for your device are already installed”. If you believe the is a newer version available while it is not being offered by the Windows update process, you will need to manually download and execute the installer as described earlier. This can happen on older Windows versions with no update support for the device.

Solving problems with the Intel UHD Graphics device

With the right drivers, your Intel UHD graphics 620 device should operate without problems. But an incorrect or outdated driver or even device configuration problems can cause the graphics device to have issues. Possible scenarios are a blue screen, flickering screen, no support for a dual monitor, animation issues with Windows Desktop on Windows 10 and Windows 11, and more.

These problems, in most cases, are caused by driver issues. Apart from the above-described driver installation process, there are other steps that can be used to solve graphics problems with the Intel UHD 620.

Reinstalling the Intel UHD graphics 620 device

If the driver is correct, but the driver and/or device configuration is a problem, reinstalling the device can solve it.

Open the Device Manager as described in the earlier steps.
In the Device Manager, open the Display adapters
Right-click the Intel UHD Graphics 620 device, and in the popup menu select Uninstall device.
In the Uninstall Device confirmation window, leave the Attempt to remove the driver for this device unchecked and click the Uninstall
Note: depending on the Windows version, the checkbox might be labeled “Delete the driver software for this device”.
After the device uninstall completes, reboot the computer to automatically reinstall the device with the existing driver.

If these steps do not fix your issue, repeat the steps to uninstall the device, but this time also uninstall the driver using the checkbox.

Rollback the driver to the previous version

In some cases, the graphics problems can be caused by a newer or incorrect version of the device driver. In this scenario, you want to revert back to the previous, working version of the Intel UHD graphics 620 driver. That can also be done using the device manager.

Open the Device Manager as described in the earlier steps.
In the Device Manager, open the Display adapters
Right-click the Intel UHD Graphics 620 device, and in the popup menu select Properties.
In the Properties dialog box, click the Driver
Next, click the Roll Back Driver button.
Follow the on-screen instructions to confirm the driver rollback operation.

Note: If the Roll Back Driver button is grayed out, that means no previous version of the driver for the device is available.

Recommended: find and download the latest drivers for your PC devices automatically by using DriverFinder.

Fix MediaTek MT7921 Wi-Fi 6 Problem with Windows 11

The MediaTek MT7921 Wi-Fi card from Taiwanese manufacturer MediaTek was introduced in 2021. The wireless card was first used by Asus in their ROG and TUF gaming laptops. The new MediaTek chipset has improved wireless network connectivity, offering better performance and improved battery life.

All great of course, but with Windows 11, there are reports that the MediaTek MT7921 is not working after the June 2022 update of Windows 11. Problems vary from intermittent connectivity, no Wi-Fi device showing at all, and device errors (This device cannot start. (Code 10).

Install the MediaTek MT7921 Driver

The primary cause of such problems is the device driver. So the first thing to try is to uninstall the MediaTek MT7921 device in the Device Manager and reinstall the driver.

To uninstall and reinstall the MediaTek MT7921 driver:

Open the Device Manager from the Start menu.
In the Device Manager, click on Network adapters to expand the category and show the devices.
Next, right-click the WIFI 6 MediaTek MT7921 device, and in the popup menu select Uninstall.

After this you have a few options:

Restart the PC, in which case Windows will reinstall the device (but most likely using the same driver). You can also use the Action menu and select Scan for hardware changes to reinstall the device.
– or –
Use the MyASUS app (available in the Microsoft Store).

Note: The screenshot is for illustration only, and shows the Intel WLAN Driver instead of the MediaTek MT7921 Driver.
1. Go to the Customer Support section (1).
2. Select LiveUpdate. (2)
3. Select Latest. (3)
4. Under Networking, locate the wireless driver and click the download icon. (4)
5. Select a folder to download the driver to and click OK.
6. Once the download completes, the download icon will change into a folder icon. Click it to open a File Explorer window with the downloaded file.
7. Click the downloaded driver installer to install the driver.

If the device re-install or the driver update did not fix the problem, you might need to reset the BIOS. This was reported as having worked for a system with BIOS version 310. It is not certain this will work for other versions, but it is a possible solution.

To load the Asus default BIOS settings:

With the system showing the Windows 11 desktop, press the power button and hold it for 20 seconds.
Press and hold the F2 key, and then press the power button again to turn on the computer. This will get you into the BIOS.
Click Default(F9) at the bottom of the screen, or press the F9 key on the keyboard.
Next, click the OK button to confirm.
Click Save & Exit(F10) at the bottom of the screen, or press the F10 key on the keyboard.
And finally, click OK again to confirm saving the changes with the default settings loaded.

The computer will reboot and start Windows 11.

Use a third-party driver

In general, is best to use a Microsoft driver or a driver from the computer or hardware manufacturer. But there is a difference in how fast different manufacturers release updated drivers for devices. And in the case of the MediaTek MT7921, the driver from ASUS might not be the latest driver.

If the Windows driver or the ASUS driver do not fix the problems with your MediaTek MT7921 Wi-Fi 6 card, try downloading and installing the Lenovo driver. This might sound weird, but the driver installer is the only real difference. The driver itself is for the exact same MediaTek device.

After the download completes, run the installer, and follow the on-screen instructions to extract and install the driver. If this does not help, you can uninstall it again after, or use a driver rollback to go back to the previous version.
