Realtek GbE Family Controller Driver for PC (Windows 11/10): Download & Install

The Realtek GbE Family Controller is a wired Ethernet network adapter commonly found in desktop computers, laptops, and motherboards. It allows Windows to communicate with a wired network through an Ethernet cable. The adapter depends on a compatible network driver to work correctly.

If the Ethernet connection is missing, frequently disconnects, shows a yellow warning icon in Device Manager, or stops working after reinstalling Windows, the Realtek network driver may need to be installed or updated.

Realtek provides software packages for its PCIe FE, GbE, and newer 2.5GbE and faster Ethernet controllers. Its current download page includes Windows 10 and Windows 11 packages for supported controllers.

In this guide, I will explain how to identify your Realtek controller, download the appropriate driver, install it manually, and update it through Windows.

Realtek GbE Family Controller

GbE stands for Gigabit Ethernet. A Realtek GbE Family Controller is a wired network adapter that connects your computer to a router, modem, switch, or other Ethernet network.

The exact hardware can vary. For example, Realtek’s PCIe Gigabit Ethernet family includes controllers such as RTL8111B, RTL8111C, RTL8111E, RTL8111G, RTL8111H, RTL8168B, RTL8168E, RTL8168G, and RTL8168H. Realtek also provides separate drivers for 2.5GbE and faster controllers.

The driver acts as the communication layer between Windows and the Ethernet hardware. Without a suitable driver, Windows may not recognize the adapter correctly, or the Ethernet connection may not function.

You may see the adapter listed in Device Manager as Realtek PCIe GbE Family Controller or with a similar name. 

Microsoft explains that Device Manager displays device information, including the manufacturer, device status, and installed driver details.

Realtek GbE Family Controller Driver for PC (Windows 11/10): Download & install

There are several ways to get the correct driver. The most straightforward method is to use the computer or motherboard manufacturer’s support page, because manufacturers sometimes customize the Realtek driver for a particular system.

Another option is the official Realtek download page, especially when you know that your computer uses a compatible Realtek PCIe GbE controller. Realtek currently lists a Win10/Win11 Auto Installation Program (NDIS) and a DASH all-in-one installer for supported Ethernet controllers.

You can also use Windows Update or Device Manager. Microsoft says Windows can automatically obtain recommended hardware drivers through Windows Update, while Device Manager can be used for automatic or manual driver installation.

The following steps cover these methods in a beginner-friendly way.

Step 1: Check Your Windows Version and System Type

Before downloading a driver, first check which version of Windows you are using.

Press Windows + I to open Settings. In Windows 11, select System and then select About. In Windows 10, open Settings > System > About.

Look for Windows specifications to confirm whether you are running Windows 11 or Windows 10. You should also check System type to see whether your PC is running a 64-bit operating system.

This information matters because driver packages can be designed for particular Windows versions and system architectures. Microsoft also recommends making sure that manually downloaded drivers match the Windows version and architecture installed on the computer.

Step 2: Identify the Realtek Ethernet Controller

Next, check exactly which network adapter is installed on your PC.

Right-click the Start button and select Device Manager. Expand Network adapters.

Look for an entry containing Realtek, such as Realtek PCIe GbE Family Controller.

If you see a yellow exclamation mark beside the adapter, Windows has detected a problem with the device or its driver. Device Manager can also display information about the driver and device status through the adapter’s Properties window.

If the Realtek adapter does not appear under Network adapters, select View > Show hidden devices in Device Manager. If it still does not appear, check Other devices for an Ethernet Controller or Unknown device.

Step 3: Download the Driver From Your PC or Motherboard Manufacturer

For many users, the PC or motherboard manufacturer’s website is the safest place to begin.

If you have a Dell, HP, Lenovo, ASUS, Acer, MSI, Gigabyte, ASRock, or another branded computer or motherboard, open its official support page.

Enter your computer model, motherboard model, or service tag when requested. Open the driver section and look for LAN, Ethernet, Network, or Realtek LAN Driver.

Download the package that corresponds to your version of Windows.

This method can be preferable when the manufacturer supplies a customized driver for the particular hardware. Microsoft also recommends checking the hardware manufacturer’s website when Windows Update cannot find a suitable driver.

Step 4: Download the Driver From Realtek

If you prefer to obtain the package directly from Realtek, open the company’s official Network Interface Controllers download section.

Realtek lists its PCIe FE / GbE / 2.5GbE / 5G / 10G Family Controller Software on its download page. For traditional Gigabit Ethernet controllers, look under the 10/100/1000M Gigabit Ethernet section.

For supported Windows systems, Realtek currently lists a Win10/Win11 Auto Installation Program (NDIS). The page also lists a DASH all-in-one Installer for Win10/Win11 for applicable hardware.

Do not assume that every Realtek Ethernet driver works with every Realtek adapter. The controller family and hardware ID determine compatibility.

Step 5: Extract the Downloaded Driver

After downloading the driver, open your Downloads folder.

If the downloaded file is a ZIP archive, right-click it and select Extract All. Choose a convenient folder and select Extract.

Open the extracted folder and look for an installation program such as Setup.exe or a similar executable.

Some driver packages instead contain files such as .INF, .SYS, and .CAT files. These are driver package components and can be installed manually through Device Manager if an executable installer is not provided.

Step 6: Install the Realtek Driver

If the package contains an installer, double-click the installation file.

Windows may display a User Account Control prompt asking whether you want to allow the program to make changes to your device. Select Yes if you downloaded the driver from a trusted official source.

Follow the instructions displayed by the installer. The installation may temporarily reset the Ethernet connection, so do not be concerned if the wired connection briefly disconnects.

When the installation finishes, restart your computer if prompted.

A restart is useful because Windows can reload the newly installed network driver and initialize the Ethernet adapter again.

Step 7: Install the Driver Manually Through Device Manager

If the downloaded package does not have a working setup program, you can install the driver through Device Manager.

Open Device Manager and expand Network adapters. Right-click Realtek PCIe GbE Family Controller and select Update driver.

Select Browse my computer for drivers. Select Browse, navigate to the folder containing the extracted Realtek driver files, and select that folder.

Make sure Include subfolders is selected if the option is available. Select Next.

Windows will search the selected folder for a compatible driver and install it if an appropriate package is found. Microsoft documents this manual installation process for downloaded manufacturer drivers.

Step 8: Update the Driver Through Windows Update

You do not always need to download the driver manually.

In Windows 11, open Settings > Windows Update > Advanced options > Optional updates. If compatible driver updates are available, select the relevant network driver and choose Download and install.

In Windows 10, open Settings > Update & Security > Windows Update, then check for available updates and optional driver updates.

Microsoft notes that Windows Update can provide recommended drivers for hardware, including network adapters. Optional driver updates, however, are not installed automatically.

After the driver installation completes, restart the computer.

Step 9: Update the Realtek Driver Using Device Manager

Another simple option is to let Device Manager search for a driver.

Right-click Start, select Device Manager, expand Network adapters, right-click the Realtek adapter, and select Update driver.

Select Search automatically for drivers. Windows will check for a suitable driver.

If Windows does not find a newer driver, you can also check Windows Update for available driver updates. Microsoft provides this automatic Device Manager method for Windows 10 and Windows 11.

Step 10: Restart and Test the Ethernet Connection

After installing the driver, restart your computer.

Connect an Ethernet cable between your PC and router or network switch. Open Settings > Network & internet and check whether the Ethernet connection is recognized.

You can also open a web browser and visit a website to test Internet connectivity.

If the Ethernet connection works normally and the Realtek adapter no longer shows a warning icon in Device Manager, the driver installation was successful.

Step 11: Verify the Installed Driver Version

You can check the installed driver version whenever you want to confirm that Windows is using the newly installed package.

Open Device Manager, expand Network adapters, right-click the Realtek controller, and select Properties.

Open the Driver tab. You can view information such as the Driver Provider, Driver Date, and Driver Version.

Compare this information with the driver package you downloaded if you need to verify the installation.

Additional Tips

Always download Realtek drivers from the official Realtek website or your computer and motherboard manufacturer’s official support website. Microsoft specifically advises avoiding driver downloads from websites other than the manufacturer’s official site.

If your Ethernet connection stopped working immediately after a driver update, open the Realtek adapter’s Properties > Driver tab and check whether Roll Back Driver is available. Microsoft documents driver rollback as an option when a recent update causes a problem.

If Windows cannot find the adapter at all, check whether Ethernet is enabled in the system firmware and whether the network adapter appears under Other devices in Device Manager.

If you are reinstalling Windows and have no Internet connection, download the appropriate Realtek driver on another computer and copy the installer to the affected PC using a USB flash drive.

Also remember that Realtek GbE, Realtek 2.5GbE, and other Ethernet controller families are not necessarily interchangeable. Identify the actual controller before choosing a driver.
