The Realtek GbE Family Controller is a network adapter used by many desktop computers and laptops to provide a wired Ethernet connection. If Windows cannot detect your Ethernet connection, shows a yellow warning icon in Device Manager, or reports that the network adapter driver is missing, installing the correct Realtek driver can often resolve the problem.
Windows can sometimes install a suitable network driver automatically through Windows Update. However, you may need to install the driver manually after reinstalling Windows, upgrading your PC, replacing hardware, or troubleshooting an Ethernet connection. Realtek currently provides Windows 10 and Windows 11 driver packages for several PCI Express Gigabit Ethernet controllers, while Microsoft also distributes compatible Realtek networking drivers through Windows Update and the Microsoft Update Catalog.
The important part is choosing a driver that matches your Realtek network controller, Windows version, and system architecture.
Installing a random driver package can leave the Ethernet adapter unavailable or cause compatibility problems.
How to Download & Install Realtek GbE Family Controller Driver on PC (Windows 11/10)

Before downloading anything, it helps to understand what you are looking for. The name Realtek GbE Family Controller generally refers to a Realtek Gigabit Ethernet controller connected through PCI Express. Realtek’s current PCIe Ethernet software covers several controller families, including RTL8111, RTL8168, and other related chips.
Your computer may display a slightly different name depending on the exact controller and driver version.
That’s why checking the hardware information first is important.
Step 1: Check Your Windows Version
Start by confirming which version of Windows is installed on your PC. This prevents you from downloading a package intended for a different operating system.
Press Windows + I to open Settings. In Windows 11, go to System > About. In Windows 10, go to System > About as well. Look under Windows specifications to see your edition and version.
Next, find System type under Device specifications. Most modern PCs use a 64-bit operating system, but it is still worth checking before installing a driver.
You can also press Windows + R, type winver, and select OK to quickly check your Windows version.
Step 2: Identify the Realtek Ethernet Controller
Before downloading the driver, identify the network adapter currently installed on your computer.
Press Windows + X and select Device Manager. Expand Network adapters and look for an entry containing Realtek, GbE, PCIe, or Ethernet.
If the driver is missing, the adapter may appear under Other devices as Ethernet Controller with a yellow warning icon. This is a useful clue that Windows recognizes the hardware but does not have the appropriate driver installed.
Right-click the device, select Properties, and open Details > Hardware Ids. The hardware ID can help you match the correct driver when several Realtek packages look similar.
Step 3: Choose the Correct Driver Source
The safest approach is to start with your PC or motherboard manufacturer’s support page because manufacturers sometimes customize network drivers for a particular computer model.
For example, if you have a Dell, HP, Lenovo, ASUS, Acer, MSI, Gigabyte, or another branded computer, search the manufacturer’s support section using your exact model number. Look for a category such as Network, LAN, or Ethernet.
If you need a driver directly from Realtek, use the Realtek PCIe FE/GbE/2.5GbE/5G/10G Family Controller Software section and select the Windows package that matches your hardware. Realtek lists current Windows 10 and Windows 11 Auto Installation Programs for its PCIe Ethernet controllers.
Avoid downloading drivers from unfamiliar third-party driver websites. A driver package should come from a trusted manufacturer or Microsoft distribution channel whenever possible.
Step 4: Download the Realtek Driver
Once you have identified the appropriate package, download it to your computer. Realtek’s current Windows packages are generally provided as downloadable installation archives. The exact file format and installer can vary between driver releases.
Before opening the downloaded file, make sure you know where it was saved. In most cases, it will be in Downloads.
If the download is a ZIP file, right-click it and choose Extract All. Select an easy-to-find folder, such as your desktop or Downloads folder, and extract the files.
If the package is already an executable installer, you can usually double-click it to begin the installation.
Step 5: Run the Driver Installer
Open the extracted driver folder and look for a setup application, often named something similar to Setup.exe or another installation program supplied with the package.
Double-click the installer. If Windows displays a User Account Control prompt asking whether you want to allow the program to make changes, check that the publisher is trustworthy and select Yes when appropriate.
Follow the installation wizard. You may see options to install, repair, or remove the existing Realtek driver. If you are installing the driver for the first time, choose the normal installation option.
Allow the installer to complete without shutting down the computer.
Step 6: Install the Driver Through Device Manager
If the downloaded package does not include a working installer, you can install the driver manually through Device Manager.
Open Device Manager > Network adapters or Other devices. Right-click the Realtek Ethernet controller and select Update driver.
Choose Browse my computer for drivers. Select the folder containing the extracted Realtek driver files and make sure the option to include subfolders is selected.
Continue through the prompts. Windows will search the selected folder for a compatible driver and install it if it finds one.
This method is particularly useful when you have downloaded an INF-based driver package rather than a traditional setup program.
Step 7: Restart Your PC
After the installation finishes, restart your computer even if Windows does not require an immediate restart.
Select Start > Power > Restart and allow Windows to boot normally.
Restarting gives Windows an opportunity to properly initialize the newly installed network driver and reload the Ethernet adapter.
Once Windows starts again, connect your Ethernet cable and wait a few seconds. Your PC should attempt to establish a wired network connection.
Step 8: Verify the Realtek Driver Installation
Now confirm that the driver was installed correctly.
Press Windows + X > Device Manager, then expand Network adapters. You should see your Realtek Ethernet controller listed without a yellow warning icon.
Right-click the adapter and choose Properties. Under the General tab, check the Device status area. A properly installed adapter should report that the device is working properly.
To check the installed driver information, open Properties > Driver. You can review the Driver Provider, Driver Date, and Driver Version.
If the adapter appears normally and your Ethernet connection works, the installation is complete.
Step 9: Test the Ethernet Connection
Connect your Ethernet cable directly from your PC to your router, modem, or network switch.
Then open Settings > Network & internet > Ethernet in Windows 11. In Windows 10, go to Settings > Network & Internet > Ethernet.
Check whether Windows identifies the Ethernet connection and provides network access.
You can also open a web browser and visit a few normal websites. If the connection works consistently, the Realtek driver is functioning correctly.
If Windows still reports No Internet, the driver may not be the only problem. The Ethernet cable, router port, network configuration, or Internet service could also be responsible.
Step 10: Use Windows Update if the Driver Does Not Work
If the manually installed driver causes problems, Windows Update is another option.
Open Settings > Windows Update in Windows 11. In Windows 10, open Settings > Update & Security > Windows Update.
Select Check for updates and allow Windows to search for available driver updates.
Microsoft’s Update Catalog contains Realtek networking drivers for different Windows versions and hardware configurations. Current catalog entries include Realtek networking packages for Windows 10 and Windows 11, although the correct package depends on your specific hardware and Windows release.
Do not assume that the newest-looking driver is automatically the correct one. Compatibility with your particular controller matters more than the version number alone.
