A missing or outdated Wi-Fi driver can cause wireless networks to disappear, prevent a computer from connecting to Wi-Fi, or lead to frequent connection problems. If your Windows PC uses a Realtek wireless adapter, installing the correct driver can help restore normal wireless connectivity.
Realtek produces many different wireless chipsets, so it is important to identify your exact adapter before downloading a driver. The correct driver can depend on the wireless chipset, computer model, Windows version, and sometimes the manufacturer’s customized hardware configuration.
Windows 10 and Windows 11 can install many drivers automatically through Windows Update, but you may need to manually download a driver when Windows cannot identify the adapter or when the manufacturer provides a newer compatible version.
Method 1: Identify the Realtek WiFi Adapter
The first step is to find the exact wireless adapter installed on your PC.
- Press Windows + X.
- Select Device Manager.
- Expand Network adapters.
- Look for an entry containing Realtek and Wireless or WLAN.
- Write down the complete adapter name.
If the wireless driver is missing, the adapter may instead appear under Other devices as Network Controller.
You can get additional information from the hardware ID:
- Right-click the wireless adapter.
- Select Properties.
- Open the Details tab.
- Open the Property dropdown.
- Select Hardware Ids.
- Note the displayed values.
The hardware ID can help identify the correct chipset when the normal adapter name is unavailable.
Method 2: Download the Driver From Your PC Manufacturer
For most laptops and prebuilt desktop computers, the manufacturer’s support website is the best place to download a Realtek Wi-Fi driver.
Start by finding the exact model of your computer.
- Visit your PC manufacturer’s official support website.
- Enter the computer model, serial number, or service tag.
- Open the Drivers or Downloads section.
- Select Windows 10 or Windows 11.
- Look for Wireless LAN, WLAN, or Wi-Fi.
- Check that the driver is listed for a Realtek adapter.
- Download the driver package.
- Open the downloaded installer.
- Follow the installation instructions.
- Restart your PC.
Manufacturers such as Dell, HP, Lenovo, ASUS, Acer, and MSI can provide drivers specifically tested for their hardware.
This is often preferable to downloading a generic driver because laptop manufacturers can customize wireless drivers for particular models.
Method 3: Download the Realtek WiFi Driver
If you know the exact Realtek wireless chipset, you can check Realtek’s official download resources.
- Open Realtek’s official website.
- Go to its Downloads section.
- Find the wireless LAN or WLAN category.
- Locate your specific chipset or product family.
- Check the supported Windows versions.
- Download the appropriate driver.
- Extract the package if necessary.
- Run the installer.
- Restart Windows after installation.
Do not select a driver simply because its name contains “Realtek WiFi.” Realtek manufactures many wireless adapters, and the driver must match your hardware.
If you are unsure about the chipset, return to Device Manager and check the adapter name or hardware IDs before downloading anything.
Method 4: Install the Realtek Driver Through Windows Update
Windows Update can automatically find compatible hardware drivers.
- Press Windows + I.
- Select Windows Update.
- Click Check for updates.
- Install available updates.
- Select Advanced options.
- Open Optional updates.
- Expand the available driver updates if shown.
- Look for a Realtek wireless driver.
- Install it.
- Restart the computer.
This method is useful when you do not want to manually search for a driver.
However, Windows Update does not necessarily provide every driver version available from the computer manufacturer. If Wi-Fi is still not working, check the manufacturer’s support page.
Method 5: Install the Downloaded Driver Manually
If you already downloaded a Realtek driver, you can install 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 driver.
- Make sure Include subfolders is enabled.
- Click Next.
- Allow Windows to install the compatible driver.
- Restart the PC.
If the driver is supplied as a normal executable installer, you can usually double-click the downloaded file instead.
If Windows identifies the adapter as Network Controller, right-click that device and use the same Update driver process.
Method 6: Download the Driver on Another Computer
If your Wi-Fi driver is missing, your PC may not have an internet connection. You can download the driver using another device and transfer it with a USB drive.
- Use another computer with internet access.
- Find your affected PC’s exact model.
- Open the manufacturer’s support website.
- Download the appropriate Realtek wireless driver.
- Copy the installer to a USB flash drive.
- Connect the USB drive to the affected PC.
- Copy the driver installer to the computer.
- Run the installer.
- Restart Windows.
- Connect to your wireless network.
This is one of the easiest solutions when the computer’s only internet connection depends on the Realtek adapter.
If possible, download the driver before uninstalling an existing working driver.
Method 7: Reinstall the Realtek WiFi Driver
Reinstalling the driver can resolve problems caused by corrupted or incorrectly installed driver files.
First, make sure you have a compatible driver available.
- Press Windows + X.
- Select Device Manager.
- Expand Network adapters.
- Right-click the Realtek wireless adapter.
- Select Uninstall device.
- Confirm the removal.
- Restart the computer.
Windows may automatically reinstall a compatible driver after restarting.
If it does not, manually install the Realtek driver you downloaded earlier.
After installation:
- Open Device Manager.
- Expand Network adapters.
- Check that the Realtek adapter appears normally.
- Open its Properties.
- Check the Device status section.
A yellow warning icon can indicate that the driver is still missing or experiencing a problem.
Method 8: Check the Installed Driver Version
After installing the Realtek Wi-Fi driver, verify that Windows is using the expected version.
- Open Device Manager.
- Expand Network adapters.
- Right-click the Realtek wireless adapter.
- Select Properties.
- Open the Driver tab.
You can view information such as:
- Driver Provider
- Driver Date
- Driver Version
- Digital Signer
You can compare the installed version with the driver available from your PC manufacturer’s support website.
If the newer driver causes problems, you may also find a Roll Back Driver option in Device Manager. This can be useful when Wi-Fi stops working immediately after a driver update.
Troubleshoot Realtek WiFi After Installing the Driver
If the driver is installed but Wi-Fi still does not work, check the following:
- Make sure Wi-Fi is enabled in Windows.
- Restart the computer.
- Check whether Airplane mode is turned off.
- Confirm that the Realtek adapter is enabled in Device Manager.
- Check for a physical Wi-Fi switch or keyboard shortcut on a laptop.
- Restart the router.
- Test another wireless network.
- Check Windows Update.
- Reinstall the driver if necessary.
You can also open Settings > Network & internet > Wi-Fi to check whether Windows recognizes the wireless connection.
If the adapter has a warning icon in Device Manager, open its Properties and review the displayed error message.
Conclusion
Downloading the correct Realtek Wi-Fi driver can solve many wireless problems on Windows 10 and Windows 11. The most important step is identifying the exact wireless adapter before installing anything.
For laptops and branded desktop PCs, the computer manufacturer’s support website is generally the best starting point because the driver is matched to the specific hardware. If you know the exact Realtek chipset, you can also use Realtek’s official download resources.
Windows Update provides another convenient way to obtain compatible drivers, while Device Manager can be used to manually install or reinstall a downloaded driver.
If the affected computer has no internet connection, download the driver on another computer and transfer it using a USB flash drive. After installation, verify the driver version and confirm that the Realtek adapter appears normally in Device Manager.
