When installing drivers for your Asus Motherboard, you might face a common problem where the LAN Driver does not install properly and gives an error message such as “Windows was unable to install your Network Controller“. This issue affects various Asus Motherboard models, including the ROG STRIX B550 series. It usually occurs due to outdated Windows versions or corrupted driver files.
To assist you with resolving this problem and ensuring a successful LAN Driver installation, we’ve created this guide with quick, straightforward, and guaranteed solutions.
1. Download the LAN Driver from the Asus Website
If you are downloading drivers from the CD that came with your Asus Motherboard but the LAN or Wi-Fi Driver is not installing, one of the possible reasons is that the file on the CD is corrupted.
Luckily, you can get around this problem by simply downloading the LAN Driver file from the Asus website. To do this, you’ll first need to know the exact model of your motherboard.
1.1 Finding the Model of Your Motherboard
To do that, you can either look at the manual that came with the motherboard or you can open System Information on your PC. To do the latter, follow the steps listed below:
- Press Windows Key + R at the same time to open the Run dialog box.
- In the search bar, type msinfo32 and press enter.
- In the System Information Window, look at the “System Model.”
1.2 Downloading the Driver File
Now that you know the exact model of your motherboard, you can go online and download its drivers. Since you currently don’t have access to the internet on your system due to the LAN Driver, there are three ways for you to download it.
The first way is to connect your phone to your PC using a USB cable and then enable USB Tethering on your phone to share your phone’s Wi-Fi with your PC. You can find this option in your phone’s settings.
The second way is to download the file on your phone and transfer it to your PC using a USB cable or Bluetooth (if your Motherboard supports it).
The third way is to use a USB (or a portable SSD/HDD) and another system that has an active internet connection. You can download the drivers on the system, copy the files to the USB, and then use the USB to transfer the files to your PC.
Once you’re ready to download the driver file, follow the steps written below to download it:
- Open this website.
- Use the search bar to select the model of your motherboard.
- Click on “Driver and Utility” on the right.
- On the new website that opens, select your OS.
- Download the LAN Driver.
1.3 Installing the Drivers
Once you’ve downloaded the zip file and transferred it to your PC, you can finally start installing the drivers. The best way to do so is through Device Manager. Follow the steps listed below to install the LAN Drivers:
- Create a folder named “LAN Drivers” anywhere on your PC.
- Right-click on the zip file and extract it in the folder you just created.
- Once it’s done extracting, press the Windows Key + X at the same time and select Device Manager.
- Click on the small arrow next to “Network Adapters” to expand it.
- Right-click on the “Network Controller” device.
- Click on “Update Drivers.”
- Select the “Browse my computer for drivers” option.
- Press the “Browse” button and select the LAN Drivers folder (make sure “Include subfolders” is selected).
- Press the Next button and install the driver.
- Wait for the installation to finish.
Once the driver has finished installing, restart your PC. After it boots back up, your Ethernet/Wi-Fi should finally start working without any issues.
However, if you encounter an error message while installing the drivers, it means that the drivers are likely not compatible with your version of Windows. In this case, try the next solution listed below.
2. Update Windows to the Latest Version
Before you perform this step, it’s very important to check what version of Windows you’re actually running. If you’re already running the latest version of Windows, then your OS version is not the cause of the issue. To check your Windows version, simply press Windows Key + R together, type winver and press enter.
As of September 2023, the latest version of Windows 10 and 11 is 22H2. So if you’re running an older version, follow the rest of the steps in this solution. And if you’re already running the latest version, skip to the next solution in this guide.
To update your Windows to the newest version, you’ll have to use the Media Creation Tool. If you’re connected to the internet on your PC through USB Tethering, you can download it on the PC directly. But if you’re unable to use USB Tethering, you’ll have to download it on another PC that has an active internet connection. This is because an active internet connection is required for the tool to work.
This tool will allow you to download an ISO file of the newest Windows update. You can then use the file to update your Windows.
To use the Media Creation Tool to update your Windows, follow the steps we’ve listed below:
- Visit this website.
- Click on the “Download tool now” button and wait for the file to finish downloading.
- Once the file has finished downloading, right-click on the file and press “Run as administrator.”
- When the program opens, it will take a few minutes to load before you can do anything with it. The time it takes to load will depend on the power of your system – it may take up to 10 or more minutes.
- Once the tool loads up, press the Accept button to accept the license agreement.
- Select the “Create installation media” option.
- Select the appropriate language, edition, and architecture for your PC and press Next.
- Select the ISO file option and press Next.
- Select the location where you want to save the ISO file.
- Wait for the ISO file to finish downloading.
- Once it’s downloaded, press the Finish button.
Now, simply transfer this ISO file to your PC using a USB or another portable storage device. Once you’ve done that, right-click on the ISO file, click on “Open With”, and select Windows File Explorer.
After that, follow the steps written below to update your Windows:
Note: While this is a completely safe process, it’s always a good idea to create a System Restore Point just in case something unexpectedly goes wrong, such as the power to your system being disconnected during the installation.
- Right-click the “setup.exe” file and run it as administrator.
- Wait for the setup program to load.
- Accept the license agreement and press the Next button.
- In the “Ready to Install” menu, click on the “Change what to keep” option.
- Select the “Keep personal files and apps” option.
- Click Next and press the Install button to begin updating your Windows.
- Wait for the installation to finish. This may take up to 30 minutes or more, depending on how powerful your system is.
Once the installation is finished, your PC will reboot one last time and then your Windows will finally be updated. You can enter winver in the Run dialog box to confirm that your Windows has been updated to the newest version.
You can then install the LAN Drivers you downloaded earlier and they will install without any issues.
3. Contact Asus Support
If your LAN Drivers are not installing even after you’ve updated Windows, then there are some other issues plaguing your system. The best thing to do now is to contact Asus Support and ask for their professional opinion.
Asus has a knowledgeable support team that is available 24/7 for assistance.
