Manual Wi-Fi Driver Installation Guide: From Search to Configuration

• 🔧 Sites like pcidatabase.com or devicehunt.com allow you to find a driver by codes VEN_XXXX And DEV_XXXX, obtained earlier.

If you don't have internet access on the problematic PC:

1. Download the driver on another device (phone, second computer).
2. Save the file to a flash drive or external drive.
3. Transfer it to the target PC and install it manually (more on that in the next section).

Adapter manufacturer	Official download site	Peculiarities
Intel	downloadcenter.intel.com	Drivers for AX200/AX201/AX210 Updated frequently. Search by full model name.
Realtek	www.realtek.com	The site is difficult to navigate - use the search by model (for example, RTL8821CE).
Qualcomm Atheros	www.killernetworking.com	For adapters Killer (For example, Killer AX1650) download from this site, not from the general one Qualcomm.
Broadcom	Through the laptop manufacturer's website	Broadcom rarely releases drivers directly - they are usually distributed Dell, HP and others.

⚠️ Attention: If you downloaded the driver in format .zip or .exe, do not unpack it into a folder with Cyrillic characters (for example, Drivers). Use Latin, for example C:\WiFi_Driver, otherwise the installation may fail.

3. Installing the driver via Device Manager

This is the most universal method that works even if you don't have the installation executable file (.exe). Suitable for drivers in the format .inf, .sys or unpacked folders.

Step-by-step instructions:

1. Open device Manager (Win + X → Device Manager).
2. Find your Wi-Fi adapter (it may be in the section Network adapters or Other devices with an exclamation mark).
3. Right click on it → Update driver.
4. Select Search for drivers on this computer.
5. Click Select a driver from the list of already installed drivers (if the driver has already been downloaded) or Review → specify the folder with the unpacked driver.
6. Confirm the installation and wait for the process to complete.

If the adapter is not displayed in Network adapters, but there is in Other devices How Unknown device:

• 🔄 Try deleting it first (right click → Remove device), then press Update hardware configuration on the menu Action.
• 🔧 If the adapter does not appear after this, install the driver manually via Install the old device V Device Manager.

The official driver has been downloaded from the manufacturer's website. The driver files have been unpacked into a folder with a Latin name. The adapter has been disconnected from the network (if it is a USB dongle). Ready to reboot the PC after installation?

After successful installation:

• 🔄 Restart your computer (required!).
• 📶 Check if the Wi-Fi icon appears in the taskbar.
• 🔧 If the connection doesn't work, open Network parameters and try to connect to the network manually.

4. Installing the driver via the command line (for experienced users)

This method is useful if standard methods don't work or you need to install drivers on multiple devices automatically. We'll use the utility pnputil, built into Windows.

Instructions:

1. Unzip the downloaded driver into a folder (for example, C:\WiFi_Driver).
2. Open command prompt as administrator (Win + X → Command Prompt (Administrator)).
3. Enter the command to install the driver:

   pnputil /add-driver "C:\WiFi_Driver\*.inf" /install

   (replace the path with the current one).

4. Wait for the message about successful installation and restart your PC.

If you need to remove a problematic driver before installing a new one, use:

pnputil /delete-driver oemX.inf /uninstall /force

(Where oemX.inf — the name of the driver file, which can be found using the command pnputil /enum-drivers).

To check the current drivers in the system:

driverquery | find "Network"

⚠️ Attention: Teams pnputil require administrator rights. If you receive an error Access denied, make sure that the command prompt is run as administrator (right-click → Run as administrator).

What should I do if pnputil returns the error "INF file not found"?

This error occurs if the specified folder does not contain a file with the extension .inf or its structure is damaged. Check:

1. Is the path to the folder specified correctly (no typos).

2. Is the archive with the driver unpacked (sometimes .inf hidden in subfolders).

3. Is the driver compatible with your version of Windows (for example, a driver for Windows 10 may not work in Windows 11).

If the problem persists, try downloading the driver in a different format (for example, .exe instead of .zip).

5. Typical mistakes and their solutions

Even after installing the driver, Wi-Fi may not work. Let's look at the most common issues and how to fix them.

Error 1: "The driver for this device is not installed (code 28)"

• 🔄 Try updating the driver via device Manager once again, choosing Automatic search.
• 🔧 Remove the device in Dispatcher, then press Update hardware configuration.
• 📥 Download the driver from another source (for example, from the laptop manufacturer's website instead of the chip's website).

Error 2: "This device cannot start (code 10)"

• 🔄 Restart your computer - sometimes this solves the problem.
• 🔧 Roll back the driver to the previous version (in the device properties → tab Driver).
• 🛠️ Check if the driver conflicts with other network software (for example, virtual VPN adapters).

Error 3: Wi-Fi connects, but the internet doesn't work

• 📶 Check your IP settings: open Control Panel → Network Connections, right-click on Wi-Fi → Properties → Internet Protocol Version 4. Make sure the boxes are checked. Obtain an IP automatically.
• 🔄 Restart your router and PC.
• 🔧 Update your router firmware (sometimes the problem is with the router, not the driver).

Error 4: Driver crashes after reboot

• 🔄 Install the driver with the mark Install for all compatible devices (if such an option is available in the installation wizard).
• 🔧 Disable automatic driver updates in Windows:

  Control Panel → System → Advanced system settings → Hardware → Device installation settings → No, let me choose

• 🛠️ Check your computer for viruses - some malware damages drivers.

6. Alternative ways to connect to Wi-Fi without a driver

If you can't install the driver and need internet access urgently, you can use workarounds. These methods won't replace a full driver installation, but they will help you temporarily gain internet access.

Method 1: Use a USB modem or smartphone in hotspot mode

• 📱 Connect your smartphone via USB and turn it on Modem mode in the phone settings.
• 🖥️ Windows will automatically install the driver for the USB modem (if this does not happen, download it from the phone manufacturer's website).

Method 2: Connect via Ethernet and update the driver

• 🔌 Connect your PC to the router with a cable (if there is an Ethernet port).
• 📥 Download the driver for Wi-Fi via a wired connection and install it.

Method 3: Transfer the driver from another PC

• 💻 On your working computer, download the driver and save it to a flash drive.
• 🔄 Connect the flash drive to the problematic PC and install the driver manually (as described in section 3).

Method 4: Use a LiveCD or other bootable disk

• 💿 Create a bootable USB flash drive with Linux (For example, Ubuntu) - many distributions automatically detect Wi-Fi adapters.
• 📶 Connect to Wi-Fi via Linux, download the Windows driver, and transfer it to your main drive.

⚠️ Attention: If you use USB Wi-Fi adapter, and it's not detected on any system, try it on another computer. The adapter may be physically faulty. Also, make sure the USB port is working (connect another device).

7. How to avoid driver problems in the future

To avoid experiencing no Wi-Fi after a Windows update or system crash, follow these guidelines:

• 🔄 Update your drivers regularly: Even if Wi-Fi works, check for updates on the manufacturer's website 1-2 times a year.
• 💾 Create restore points: Before installing a new driver, create a rollback point (Control Panel → Recovery → Configure System Restore).
• 📁 Keep backup copies of your drivers: After successful installation, copy the folder with the driver (usually C:\Windows\System32\DriverStore\FileRepository) to an external drive.
• 🛡️ Disable automatic driver updates: Windows sometimes installs incompatible versions. To avoid this, use gpedit.msc (for Pro versions) or registry editor.
• 🔧 Check compatibility: Before purchasing a new Wi-Fi adapter, make sure that it has drivers for your version of Windows (especially important for Windows 11).

For Windows 10/11 You can disable automatic installation of drivers through Local Group Policy Editor:

1. Click Win + R, enter gpedit.msc.
2. Follow the path: Computer Configuration → Administrative Templates → System → Device Installation → Device Installation Restrictions.
3. Enable the option Prevent installation of devices using drivers that match these device installation classes and specify the class {4d36e972-e325-11ce-bfc1-08002be10318} (this is a class of network adapters).

For Windows 10/11 Home, where there is no gpedit.msc, the same result can be achieved through registry editor:

HKEY_LOCAL_MACHINE\SOFTWARE\Policies\Microsoft\Windows\DeviceInstall\Restrictions
Create a DWORD (32-bit) value named DenyDeviceIDs with a value of 1
Create a string parameter DenyDeviceIDsRetroactive with a value of 1

FAQ: Frequently Asked Questions about Installing Wi-Fi Drivers

Is it possible to install a Wi-Fi driver without internet?

Yes. Download the driver on another device (phone, second computer), save it to a flash drive, and transfer it to the problematic PC. Then install it via device Manager (as described in section 3) or the command line (pnputil).

Why does Wi-Fi disappear after rebooting after installing the driver?
This is a typical issue when there's a driver version conflict or when Windows automatically replaces the driver with its own version. Solutions:
1. Disable automatic driver updates (see section 7).
2. Install the driver with a check mark Install for all compatible devices (if there is such an option in the installation wizard).
3. Check if your antivirus is blocking the driver installation.
How do I know which driver I need for my Wi-Fi adapter?

Determine the exact adapter model (see section 1), then:

1. Go to the website of the adapter or laptop manufacturer.
2. Enter the model into the site's search engine.
3. Download the driver for your version of Windows (32-bit or 64-bit).

If you are unsure of the model, use Equipment ID (VEN and DEV) for searching on sites like pcidatabase.com.

What should I do if the driver is installed, but Wi-Fi does not find networks?
Check the following:
• 🔌 Is Wi-Fi enabled on your laptop (sometimes it is disabled by a hardware button or key combination, for example Fn + F2).
• 📶 Is the router working (check on another device).
• 🔧 Is the adapter disabled? Device Manager (right click → Engage).
• 🛠️ Does the driver conflict with software (for example, with utilities like Killer Networking Suite).
Can I use a Windows 10 driver for Windows 11?
Sometimes yes, but not always. Windows 11 is stricter about driver compatibility, especially for new adapters (e.g. Wi-Fi 6E). If Wi-Fi doesn't work or the system returns an error after installing the Windows 10 driver, download the version specifically for Windows 11 from the manufacturer's website. As a last resort, try installing the driver in compatibility mode:
1. Right-click on the file .exe or .inf.
2. Select Properties → Compatibility.
3. Check the box Run the program in compatibility mode for: and select Windows 10.
