How to Install a WiFi Driver on Windows 11
A WiFi driver is the software that lets your network card talk to Windows 11. If your WiFi adapter isn't showing up, won't connect, or keeps dropping, a missing or outdated driver is often the cause. You can install or update it three ways: let Windows find it automatically, read it from your adapter manufacturer's website, or use a driver disc if one came with your hardware.
The automatic method works first because it's fastest. If that fails, you'll need to identify your exact adapter model and read the right driver from the manufacturer. This guide walks you through each approach in the order you should try them.
Key Takeaways
- Windows 11 can often find and install WiFi drivers automatically through Windows Update, which should be your first step.
- If automatic installation fails, you need to identify your adapter model using Device Manager, then read the correct driver from the manufacturer's website.
- Most WiFi adapter manufacturers (Intel, Realtek, Broadcom, Qualcomm) host drivers on their support pages, organized by product model and Windows version.
- After downloading a driver, run the installer file or use Device Manager to point Windows to the driver folder you extracted.
- A restart is required after driver installation before your WiFi adapter will work properly.
Let Windows 11 Search for the Driver Automatically
Start here because Windows Update can find and install drivers without you hunting for them. Open Settings by pressing Windows key + I, then go to System > About and scroll down to Advanced system settings. Click Device installation settings and make sure Yes (recommended) is selected under "Do you want to search for drivers?" This tells Windows to check for missing drivers automatically.
Next, open Device Manager by right-clicking the Start button and selecting Device Manager. Look for Network adapters in the list and expand it. If your WiFi adapter appears with a yellow exclamation mark or question mark, right-click it and select Update driver > Search automatically for updated driver software. Windows will check Windows Update and your system for a matching driver.
Wait for the search to finish. If Windows finds a driver, it will install it automatically and you'll see a success message. Restart your computer and test your WiFi connection. If this works, you're done. If Windows says no driver was found, move to the next section.
Identify Your WiFi Adapter Model
To read the correct driver from the manufacturer, you first need to know exactly which adapter you have. Open Device Manager again and expand Network adapters. Look for an entry that contains "Wireless" or "WiFi" or "802.11" — this is your adapter. Right-click it and select Properties.
In the Properties window, click the Details tab. In the dropdown menu labeled Property, select Hardware IDs. You'll see a string of text that includes the vendor ID and device ID. Write down the full adapter name from Device Manager (for example, "Intel Wi-Fi 6 AX200" or "Realtek RTL8821CE Wireless LAN Controller") — this is what you'll search for on the manufacturer's website.
If your adapter shows as "Unknown device" with a yellow mark, the process is the same: note the hardware ID and search the manufacturer's support site. If you can't identify the manufacturer from the name, search the hardware ID online — it will point you to the right company and model.
read the Driver from the Manufacturer
Go to the support or downloads page of your adapter's manufacturer. The major WiFi adapter makers are Intel, Realtek, Broadcom (now part of Avago), and Qualcomm. Search their site for your adapter model and Windows 11 (specify 64-bit or 32-bit, depending on your system — check Settings > System > About to see which you have).
read the driver file to a folder you can find easily, like your Downloads folder. The file will usually be a .zip archive or an .exe installer. If it's a .zip file, right-click it and select Extract All, then choose a destination folder. Open the extracted folder and look for a file named setup.exe or install.exe — this is the installer.
If the read is already an .exe file, you can run it directly. Double-click the installer and follow the on-screen prompts. The installer will guide you through the installation, usually with just a few clicks. When it finishes, restart your computer. Windows will load the new driver on startup and your WiFi adapter should appear and work normally.
Use Device Manager to Install a Downloaded Driver
If the manufacturer's installer didn't work or you prefer not to run an .exe file, you can point Device Manager to the driver folder directly. Extract the driver .zip file if you haven't already, so you have a folder containing the driver files (.inf, .sys, and other files).
Open Device Manager, find your adapter under Network adapters, right-click it, and select Update driver > Browse my computer for drivers. Click Browse and navigate to the folder where you extracted the driver files. Select the folder (not a specific file) and click OK. Windows will search that folder for a matching driver and install it.
If Windows asks for administrator permission, click Yes. Once installation completes, restart your computer. The driver will load on startup and your WiFi should connect normally.
Troubleshoot if the Driver Still Won't Install
If you've tried both automatic and manual installation and your adapter still doesn't work, the problem may be a corrupted driver or a hardware conflict. Open Device Manager and look for any device with a yellow exclamation mark or question mark — these indicate problems. Right-click the problem device and select Uninstall device. Check the box that says Delete the driver software for this device and click Uninstall.
Restart your computer. Windows will detect the adapter again as a new device and attempt to install a driver from scratch. This often clears conflicts that prevent installation. If Windows still can't find a driver, double-check that you downloaded the correct version for your adapter model and Windows version (64-bit vs. 32-bit).
If your adapter is very old or no longer supported by the manufacturer, the driver may not be available for Windows 11. In that case, you may need to replace the adapter with a newer model that has Windows 11 drivers available.
Verify the Driver Is Working
After installation and restart, open Settings and go to Network & internet > WiFi. You should see a list of available networks. Click on your network and select Connect. Enter your WiFi password if prompted. Once connected, open a web browser and visit any website to confirm internet access.
If you want to confirm the driver version, open Device Manager, expand Network adapters, right-click your WiFi adapter, and select Properties. Click the Driver tab to see the driver version, date, and provider. This confirms the new driver is loaded and active.
Frequently Asked Questions
What's the difference between 64-bit and 32-bit drivers?
Your Windows 11 system is either 64-bit or 32-bit, and the driver must match. Go to Settings > System > About and look for "System type" — it will say either "64-bit operating system" or "32-bit operating system." read the driver that matches your system type. Most modern computers run 64-bit Windows 11.
Do I need to uninstall the old driver before installing a new one?
Not always. If you're updating to a newer version from the same manufacturer, the installer usually replaces the old driver automatically. If you're switching manufacturers or the update fails, uninstall the old driver through Device Manager first, restart, then install the new one.
Why does my WiFi still not work after installing the driver?
The driver is only one part of the connection. Check that your WiFi adapter is turned on (some laptops have a physical switch or keyboard shortcut), that airplane mode is off in Settings, and that your router is powered on and broadcasting. If those are fine, restart your computer and try connecting again.
Can I use a driver from a different manufacturer?
No. Each adapter model requires its specific driver. Using the wrong driver will not work and may cause system instability. Always read from the manufacturer of your adapter, not a generic driver site.
What if I can't find my adapter model on the manufacturer's website?
Search the hardware ID (from Device Manager Properties > Details) online along with "Windows 11 driver." This often leads to the correct product page. If the adapter is very old, the manufacturer may have discontinued support — in that case, you'll need to replace the adapter.
