A missing, outdated, or incorrect Wi-Fi driver can prevent a Windows PC from connecting to wireless networks properly. If your computer uses a Realtek wireless network adapter, installing the correct Realtek Wi-Fi driver can help restore wireless connectivity and improve compatibility.
The most important thing is to download a driver that matches your exact Realtek adapter and Windows version. Realtek provides drivers for several WLAN chipsets, including different PCIe, USB, and other wireless solutions, so there is no single Realtek Wi-Fi driver that works with every computer.
For laptops and branded desktops, the computer manufacturer’s support website is often the best place to get the correct driver because manufacturers can customize drivers for a particular model. Microsoft also recommends checking the PC manufacturer’s website when a network adapter driver needs to be manually installed.
Method 1: Find Your Realtek WiFi Adapter Model
Before downloading a driver, identify the exact wireless adapter installed on your computer.
- Press Windows + X.
- Select Device Manager.
- Expand Network adapters.
- Look for an entry containing Realtek, Wireless, WLAN, or a similar description.
- Note the complete adapter name.
For example, you might see a name containing a Realtek RTL series chipset or a Realtek wireless network adapter.
If the adapter is not visible under Network adapters, check for Network Controller under Other devices. A missing driver can cause Windows to display the hardware without its normal adapter name.
You can also open the device properties:
- Right-click the wireless adapter.
- Select Properties.
- Open the Details tab.
- Select Hardware Ids from the Property dropdown.
- Note the displayed hardware IDs.
The hardware ID can be useful when the exact Realtek model is difficult to identify.
Microsoft recommends using Device Manager to identify the wireless adapter and checking the Driver tab for the current driver version and date.
Method 2: Download the Realtek WiFi Driver From Your PC Manufacturer
For a laptop or prebuilt desktop, start with the manufacturer’s website.
This is often the safest option because the manufacturer can provide a driver specifically tested for your computer model.
- Identify your PC’s exact model number.
- Open the manufacturer’s official support website.
- Enter the model or serial number.
- Open the Drivers, Downloads, or Support section.
- Select Windows 11 or Windows 10, depending on your operating system.
- Find the Wireless LAN, Wi-Fi, or WLAN driver.
- Check whether the driver is listed as Realtek.
- Download the driver.
- Run the downloaded installer.
- Follow the instructions on screen.
- Restart the PC when installation is complete.
If you are unsure whether a driver is compatible, compare the adapter name in Device Manager with the description on the manufacturer’s download page.
This approach is especially useful for Dell, HP, Lenovo, ASUS, Acer, MSI, and other branded computers because their wireless drivers may contain device-specific configurations.
Method 3: Download the Driver Directly From Realtek
You can also check Realtek’s official download pages for compatible WLAN drivers.
Realtek maintains a WLAN download section containing multiple wireless product families and chipset models.
Realtek Wireless LAN downloads
To find the correct driver:
- Open the official Realtek download page.
- Locate the Wireless LAN ICs or WLAN NIC section.
- Find your Realtek chipset or product family.
- Open the corresponding software page.
- Check the supported Windows versions.
- Download the appropriate WLAN driver.
- Extract the downloaded package if necessary.
- Run the installer or install the supplied driver files.
- Restart Windows.
Realtek’s website lists several different WLAN families, so avoid downloading a driver simply because it says “Realtek Wireless.” The chipset must match your hardware.
Some Realtek driver pages are also relatively old, particularly for older chipsets. If your PC manufacturer provides a newer model-specific driver, that is generally the better choice.
Method 4: Download the Driver Through Windows Update
Windows Update can automatically provide compatible hardware drivers.
To check for driver updates:
- Press Windows + I.
- Select Windows Update.
- Click Check for updates.
- Install available updates.
- Open Advanced options if necessary.
- Select Optional updates.
- Look for available driver updates.
- Install the Realtek wireless driver if one is offered.
- Restart your computer.
Windows Update can be particularly useful if you do not know the exact Realtek model.
However, Windows Update may not always provide the newest driver available from the PC manufacturer. Microsoft notes that you may still find a newer driver on the manufacturer’s website even when Windows reports that the best driver is already installed. (Microsoft Support)
Method 5: Install the Realtek WiFi Driver Using Device Manager
If you already have the driver package, you can install or update it through Device Manager.
- Press Windows + X.
- Select Device Manager.
- Expand Network adapters.
- Right-click the Realtek wireless adapter.
- Select Update driver.
- Choose Browse my computer for drivers.
- Select the folder containing the downloaded driver.
- Enable Include subfolders.
- Click Next.
- Allow Windows to install the compatible driver.
- Restart the computer.
If Windows cannot find the driver automatically, make sure you selected the folder containing the actual driver files.
For driver packages containing an .inf file, Device Manager can use that file to install the driver.
If the wireless adapter is listed as Network Controller under Other devices, right-click it and select Update driver, then point Windows to the downloaded driver folder.
Method 6: Install the Driver Without an Internet Connection
If the Realtek driver is missing, your Wi-Fi may not work at all. In that situation, download the driver using another device.
You can use another computer or a smartphone with internet access.
- Identify your PC model and Realtek adapter.
- Visit the PC manufacturer’s support website using another device.
- Download the appropriate Wi-Fi driver.
- Copy the driver installer to a USB flash drive.
- Connect the USB drive to the Windows PC.
- Copy the driver to the computer.
- Run the installer.
- Restart Windows.
Microsoft specifically recommends downloading the required network adapter driver on another computer and transferring it by USB when the affected PC cannot connect to the internet.
Keep a copy of the working driver on the USB drive until you confirm that Wi-Fi is functioning correctly.
Method 7: Reinstall the Realtek WiFi Driver
Reinstalling the driver can help when Wi-Fi stopped working after a driver update or when the existing driver has become corrupted.
First, download a compatible replacement driver so you have it available.
Then:
- Press Windows + X.
- Select Device Manager.
- Expand Network adapters.
- Right-click the Realtek wireless adapter.
- Select Uninstall device.
- If available, select the option to attempt to remove the driver.
- Click Uninstall.
- Restart the PC.
After restarting, Windows may automatically reinstall the network adapter driver. Microsoft recommends this procedure as one troubleshooting option for network adapter problems.
If Windows does not reinstall the driver, manually install the driver you downloaded earlier.
Do not uninstall the driver before obtaining a replacement when your computer depends entirely on that adapter for internet access.
Method 8: Verify That the Realtek WiFi Driver Is Working
After installing the driver, confirm that Windows recognizes the wireless adapter correctly.
- Open Device Manager.
- Expand Network adapters.
- Find the Realtek wireless adapter.
- Right-click it and select Properties.
- Open the General tab.
- Check the Device status section.
You should not see a yellow warning icon or an error message.
Next, open Settings > Network & internet > Wi-Fi and check whether Wi-Fi is available.
You can also test the connection by selecting a nearby wireless network and connecting to it.
To check the installed driver version:
- Open the Realtek adapter’s Properties.
- Select the Driver tab.
- Check Driver Provider, Driver Date, and Driver Version.
You can compare this information with the driver offered by your PC manufacturer.
If the adapter still does not work, Microsoft recommends checking whether it is disabled in Device Manager and verifying that the installed driver is current.
Conclusion
Downloading the correct Realtek Wi-Fi driver is important when Wi-Fi is missing, unstable, or not working correctly on Windows 10 or Windows 11. The first step should always be identifying the exact wireless adapter and computer model.
For laptops and branded PCs, the manufacturer’s support page is usually the best place to obtain a compatible driver. You can also use the official Realtek WLAN download pages when you know the exact chipset.
Windows Update and Device Manager provide additional ways to update or install the driver. If the computer has no internet connection, download the driver on another device and transfer it using a USB drive.
Avoid installing a random Realtek driver simply because it has the Realtek name. Different wireless chipsets require different drivers, and using the wrong package may fail to install or may not properly support your hardware.
