Wireless Internet has become an integral part of everyday life, but what to do if your laptop suddenly stops seeing Wi-Fi networks? In 90% of cases the problem lies in absence or incorrect operation of the network adapter driver. This article will help you figure out how to correctly install the Wi-Fi driver for laptops of any brands - from ASUS And Lenovo to HP And Acer, regardless of the model and version of Windows.

We will consider all possible scenarios: from automatic installation through Device Manager before manually searching for drivers by Equipment ID. We will pay special attention to typical mistakes that users make during installation, and provide recommendations for diagnosing problems. If you have never encountered updating drivers before, don’t worry, the instructions are adapted for beginners with step-by-step screenshots and explanations.

1. How to understand that the problem is in the Wi-Fi driver

Before proceeding with the installation, it is important to make sure that the problems are indeed related to the driver. Here are the key signs:

  • 🔍 The laptop does not see any Wi-Fi networks, although other devices connect normally
  • 🚫 There is no wireless network icon in the tray (or it is crossed out with a red cross)
  • ⚠️ B Device Manager There is a yellow exclamation mark next to the network adapter
  • 🔄 Wi-Fi periodically turns off or works at extremely low speeds

If at least one of these symptoms is present, there is a 99% chance that the driver is to blame. But before installation, check the physical condition of the adapter:

⚠️ Attention: On some laptops (eg Lenovo ThinkPad or Dell Latitude) The Wi-Fi module can be disabled by a hardware button or key combination (usually Fn + F2 or Fn + F12). Make sure the adapter is not blocked at the BIOS level.

For an accurate diagnosis, open Device Manager (Win + X → Device Manager) and expand the thread "Network adapters". If there are no devices with words in the list Wireless, Wi-Fi or 802.11 — the driver is either not installed or the adapter is faulty.

2. Automatic driver installation via Windows Update

The easiest way is to use the built-in update system. This method is suitable for most modern laptops with adapters from Intel, Qualcomm Atheros or Realtek.

Instructions:

  1. Connect your laptop to the Internet via Ethernet cable or USB modem.
  2. Open Start → Settings → Update & Security → Windows Update.
  3. Click "Check for updates" and wait for the process to complete.
  4. If the system finds a driver for Wi-Fi, it will be installed automatically.

If there are no updates or Wi-Fi is still not working, move on to manual methods. Windows Update often offers outdated versions of drivers that may not support modern Wi-Fi 6 (802.11ax) standards.

Make sure the laptop is connected to power

Download the driver to another computer (if Wi-Fi does not work)

Remember the adapter model (via Device Manager)

Disable antivirus during installation -->

3. Search for a driver by hardware ID (for advanced users)

When the automatic installation did not work and the adapter model is unknown, this will help Equipment ID — unique device identifier in the system. This method is universal and works even for rare Chinese adapters.

How to find ID:

  1. Open Device Manager (Win + X).
  2. Expand "Network adapters".
  3. Right-click on the device with the exclamation mark → "Properties" → tab "Information".
  4. From the drop down menu select "Equipment ID".
  5. Copy the first line from the list (for example, PCI\VEN_168C&DEV_003E).

Now use the ID to search for the driver:

  • 🔗 Enter the copied code into a search engine (for example, PCI\VEN_168C&DEV_003E driver).
  • 🛒 Download the driver only from official sources:
  • ⚠️ Avoid sites like driverpack.io — they often install unnecessary software.
⚠️ Attention: If you see several driver versions in the search results by ID, select the one where yours is listed in the description. adapter type (For example, Intel AX200 or Realtek RTL8822CE). Installing the wrong driver may result in BSOD (blue screen of death).

4. Installing the driver from the official website of the laptop manufacturer

Laptop manufacturers (HP, Dell, Lenovo etc.) often modify standard drivers to suit their equipment. Therefore, it is better to download software from their official websites.

Algorithm of actions:

  1. Define exact laptop model (written on the sticker below or in System Information).
  2. Go to the manufacturer's support site:
  • Enter your laptop model → section "Drivers" → select your OS.
  • Find a driver for Wireless LAN or Wi-Fi and download it.

    • Pay attention to the operating system version. For example, a driver for Windows 10 x64 may not work for Windows 11, even if the bit depth is the same.

    Manufacturer Section on the site Features
    Dell dell.com/support Uses Service Tag for automatic model detection
    MSI msi.com/support Drivers are divided by laptop series (for example, Prestige, Modern)
    HP support.hp.com Requires serial number entry or automatic detection
    Lenovo pcsupport.lenovo.com Supports search by Machine Type Model (For example, 20L6S2H100)
    💡

    If the manufacturer's website does not have a driver for your version of Windows, try installing a driver for an older OS in compatibility mode. To do this, right-click on the installation file → "Properties" → "Compatibility" tab → select the previous version of Windows.

    5. Manual driver update via Device Manager

    If the driver is already installed but is not working correctly, try updating it manually. This method will also help if you downloaded the driver in advance and want to install it without running .exe-file.

    Step by step instructions:

    1. Open Device Manager (Win + X → Device Manager).
    2. Expand "Network adapters".
    3. Right click on your Wi-Fi adapter → "Update driver".
    4. Select "Search for drivers on this computer".
    5. Specify the path to the folder with the downloaded driver (if you downloaded it from the manufacturer’s website).
    6. Click "Next" and follow the instructions.

    If the system reports that "the best drivers are already installed", try first remove current driverand then repeat the installation:

    1. В Диспетчере устройств щёлкните правой кнопкой по адаптеру → "Удалить устройство".

    2. Поставьте галочку "Удалить программы драйверов для этого устройства" (если есть).
    

    3. Перезагрузите ноутбук.
    

    4. Установите драйвер заново.

    ⚠️ Attention: After removing the Wi-Fi driver, the adapter will disappear from the list of devices until you reboot. Don't be alarmed - this is normal. If the adapter does not appear after rebooting, check whether it is included in BIOS/UEFI (section Advanced → Wireless Device Enable).
    💡

    Removing the old driver before installing the new one increases the chances of successful Wi-Fi operation, especially if there were previous version conflicts.

    6. Installing the driver without the Internet (via another computer)

    What to do if Wi-Fi doesn’t work and you can’t connect to the Internet via cable? In this case, the driver can be downloaded on another device and transferred to the laptop via a USB flash drive.

    Algorithm:

    1. Determine the Wi-Fi adapter model (via Device Manager or laptop documentation).
    2. On another computer, download the driver from the official website (see section 4).
    3. Copy the files to the USB drive.
    4. Connect the USB flash drive to your laptop and start the installation.

    If you don't have a second computer, you can use mobile internet:

    • 📱 Connect your laptop to your smartphone via USB modem (turn on "Modem mode" in your phone settings).
    • 🔌 Use USB cable (not Bluetooth or Wi-Fi Direct).
    • 🌐 Download the driver directly to your laptop via your mobile connection.

    For laptops Lenovo And Dell There is an alternative way - use utilities for automatic driver detection:

    • Lenovo System Update (you can download from official website)
    • Dell SupportAssist (built into most models Dell)

    These programs will scan the system and offer to download all missing drivers, including Wi-Fi.

    What to do if the driver is installed, but Wi-Fi still does not work?

    1. Check if the service is enabled WLAN AutoConfig:

    - Click Win + R, enter services.msc

    - Find a service WLAN AutoConfig → right click → "Run"

    2. Reset network settings:

    - Open Settings → Network and Internet → Status → Network reset

    3. Check your power settings:

    - Open Device Manager → Wi-Fi adapter properties → tab "Power Management" → uncheck "Allow this device to turn off to save power"

    7. Solving common errors when installing a driver

    Even if the driver is installed correctly, problems may occur. Let's look at the most common errors and how to fix them.

    Error Reason Solution
    Code 10: This device cannot start Driver conflict or damaged files Remove the driver completely (including programs) and install again
    Code 28: Drivers for this device are not installed No compatible driver available Download the driver from the official website according to the adapter model
    Code 43: Windows has stopped this device because it has reported problems Hardware failure or incompatible driver Try rolling back the driver or test the adapter in another laptop
    Wi-Fi adapter has disappeared from Device Manager Disabled in BIOS or physically damaged Check BIOS settings and antenna connections (for removable modules)

    If after installing the driver the laptop starts spontaneously disconnect from Wi-Fi, the reason could be:

    • 🔋 Power settings (disable power saving for the adapter, as described in the spoiler above).
    • 📶 Interference from other devices (for example, microwaves or wireless headphones at a frequency of 2.4 GHz).
    • 🛠️ Driver incompatibility with the Windows version (try rolling back the system to the previous build).

    To diagnose the network, use the command line:

    ping 8.8.8.8

    netsh wlan show interfaces
    

    ipconfig /all

    If the team ping shows packet loss, the problem may be on the side of the router or provider.

    8. Alternative ways to connect to the Internet without Wi-Fi

    If installing the driver did not help, and you urgently need the Internet, use one of these methods:

    • 🔌 Ethernet cable: Connect your laptop directly to the router via LAN port.
    • 📱 USB modem: Use your smartphone in modem mode (as described in section 6).
    • 📡 4G/5G modem: Buy a USB modem from your operator (for example, MTS or MegaFon).
    • 🔄 Powerline adapter: Transmits the Internet through electrical wiring (useful if the router is far away).

    For laptops with slot m.2 there is a radical solution - Wi-Fi module replacement. Modern adapters (for example, Intel AX210) support Wi-Fi 6E and cost from 2000 rubles. The main thing is to check compatibility with your laptop model (some manufacturers, like HP, block non-original modules at the BIOS level).

    ⚠️ Attention: When replacing the Wi-Fi module, disconnect the laptop from the network and remove the battery (if it is removable). Static electricity can damage the motherboard. If you are not confident in your abilities, contact the service center.
    💡

    Before purchasing a new Wi-Fi module, check which standard your router supports. There's no point in buying Wi-Fi 6E, if the router only works on Wi-Fi 4 (802.11n).
