How to Check for Wi-Fi Drivers on Your Computer or Laptop: A Step-by-Step Guide

Lack of Wi-Fi connection is one of the most common problems faced by users of laptops and PCs with adapters. wireless communicationOften, the culprit is missing or incorrectly installed drivers, without which the operating system simply "cannot see" the network equipment. But how can you accurately determine whether the drivers are installed on your Wi-Fi adapter, and what should you do if they are missing?

In this article we will look at 5 reliable ways Wi-Fi driver checks - from standard tools Windows to specialized utilities. You'll learn how to recognize the problem by indirect signs (for example, the absence of a network icon in the system tray), where to look for information about drivers in Device Manager, and what commands will help diagnose the adapter's status through CMDWe'll also look at typical errors the system returns when drivers are missing and provide a checklist for quickly resolving the problem.

Important: If your computer has never connected to Wi-Fi (for example, after reinstalling Windows), the drivers are likely missing. If the network was working before but then disappeared, the cause could be a driver error or a conflict with system updates. In either case, our guide will help you pinpoint the source of the problem.

Signs of missing or faulty Wi-Fi drivers

Before we dive into the technical details, please note: indirect signs, which indicate problems with the wireless adapter drivers:

• 🔌 Network icon missing in the notification area (tray) - instead of the usual connection indicator, you see an empty space or a "no connection" icon.
• 🖥️ In Control Panel → Network Connections There is no "Wireless Network" option (only "Ethernet" or "Local Area Network").
• ⚠️ In Device Manager There is a yellow exclamation mark next to the network adapter or the device is marked as "Unknown".
• 🔍 When trying to connect to Wi-Fi, the system displays an error: "Unable to connect to this network" or "Windows cannot find a driver for this device.".
• 🔄 After updating Windows or drivers, the adapter is no longer detected (typical for laptops) Lenovo, HP And Dell with proprietary drivers).

If at least one of these symptoms is present, the problem is most likely related to the drivers. However, don't rush to reinstall them: first, confirm the diagnosis. For example, the absence of a network icon may be due to a disabled adapter (some laptops have a physical button or key combination to turn Wi-Fi on/off).

⚠️ Attention: On some laptop models (for example, ASUS ROG or Acer Predator) The Wi-Fi adapter may be disabled in the BIOS/UEFI. If none of the driver checks worked, check the BIOS settings (section Advanced → Onboard Devices Configuration) and make sure that the parameter Wireless LAN installed in Enabled.

Method 1: Checking via Device Manager

device Manager Driver Manager is the primary Windows tool for managing hardware. Here you can not only check for drivers, but also update, roll back, or uninstall them. To open Driver Manager:

1. Click Win + X and select device Manager.
2. Expand the section Network adapters.
3. Find the device with the names in the list Wireless, Wi-Fi, 802.11 or adapter model (for example, Intel Wi-Fi 6 AX200, Qualcomm Atheros QCA61x4).

What each option could mean:

If the adapter is found but there is an exclamation mark next to it, right-click on it and select Properties. In the tab General an error code will be indicated (for example, Code 10 — "The device cannot start." This code will help diagnose the problem more accurately.

Open Device Manager (Win + X)

Check the "Network adapters" section

Find a device with Wireless/Wi-Fi in its name

View status (exclamation mark = problem)

Write down the error code (if any)-->

Method 2: Command Prompt (CMD) for Diagnostics

If the Windows graphical interface is not available (for example, due to a system crash) or you prefer to work with commands, you can check the drivers via Command lineThis method is also useful for generating network status reports.

Open CMD as administrator (click Win + S, enter cmd, then select Run as administrator) and run the following commands:

netsh wlan show drivers

This command will output detailed information about the Wi-Fi driver, including:

• 📋 Driver name and version.
• 🔄 Supported standards (802.11n, 802.11ac, Wi-Fi 6).
• ⚡ Radio type (802.11n, 802.11ac etc.).
• ✅ Driver status (Launched or Stopped).

If you see the line in the response Driver status: Stopped, this means the driver is installed but not activated. To enable it, run:

netsh interface set interface "Wireless Network" enable

If the command returns an error No drivers found, this confirms the absence of drivers. In this case, proceed to the section "Where to download and how to install drivers."

Method 3: Checking via System Information (msinfo32)

Utility msinfo32 Provides detailed information about the system configuration, including driver information. This method is useful if you need to know the exact adapter model to search for drivers.

To open the utility:

1. Click Win + R, enter msinfo32 and press Enter.
2. Go to the section Components → Network → Adapter.
3. In the right part of the window, find your Wi-Fi adapter (search by keywords: Wireless, WiFi, 802.11).

In this section you will see:

• 🔧 Device name (For example, Intel(R) Dual Band Wireless-AC 8265).
• 📄 Driver information: supplier, version, date.
• 🔌 State: Included or Disabled.

If there are no devices mentioning Wi-Fi in the list of adapters, this means that either the driver is not installed or the adapter is disabled at the hardware level (for example, via the BIOS or a physical switch on the laptop).

⚠️ Attention: On some laptops (especially HP Pavilion And Dell Inspiron) The Wi-Fi module can be disabled by a key combination (for example, Fn + F2 or Fn + F12). Before searching for drivers, make sure that the adapter is enabled in hardware.

Method 4: Using third-party utilities (DriverPack Solution, AIDA64)

If standard Windows tools don't provide a complete picture, you can use specialized driver diagnostic programs. They will not only show whether drivers are installed but also offer to automatically update or install any missing ones.

Let's look at two popular utilities:

AIDA64

This program provides detailed information about your PC's hardware and software. To check your Wi-Fi drivers:

1. Download and install AIDA64 (there is a portable version).
2. Go to the section Devices → Windows Devices.
3. Find your Wi-Fi adapter in the list and check the driver status.

DriverPack Solution

This utility not only scans your system for drivers but also offers to install them automatically. However, be careful: the program may install additional software. To simply check your drivers:

1. Download DriverPack Solution from the official website.
2. Run the program and wait for the scanning to complete.
3. Go to the tab Drivers and find the section Network adapters.
4. If a red or yellow light is lit next to your Wi-Fi adapter, the driver is missing or out of date.

The advantage of third-party utilities is that they often recognize adapters even when Windows doesn't see them. However, for installing drivers, it's best to use official sources (see the next section).

What are the dangers of automatically updating drivers via DriverPack?

Third-party utilities like DriverPack Solution can install not only drivers but also additional software (e.g., antiviruses, browsers, and optimizers). Furthermore, they don't always select the latest or most stable driver version, which can lead to conflicts. We recommend using such programs only for diagnostic purposes and downloading drivers from the manufacturers' official websites.

Method 5: Checking via Computer Management (for advanced users)

This method is suitable for those who prefer to work with system tools. Windows without installing additional software. Tool Computer management Allows you to view detailed information about drivers, including their digital signatures and dependencies.

To open Computer management:

1. Click Win + R, enter compmgmt.msc and press Enter.
2. Go to the section Device Manager → Network Adapters (similar to method 1, but with advanced features).
3. Right-click on your Wi-Fi adapter and select Properties.
4. Go to the tab Driver, where the version, development date and supplier will be indicated.

Here you can also:

• 🔄 Update driver (button Refresh).
• 🗑️ Roll back the driver (if problems started after the update).
• 📄 View driver file details (button Intelligence).

If the tab Driver If the error message is empty or contains errors, this confirms that the driver is missing or damaged. In this case, proceed to the next section.

Where to download and how to install Wi-Fi drivers

If the check confirms that the drivers are missing or not working correctly, they need to be installed. Here 3 reliable sources, where you can download drivers:

1. Official website of the laptop/motherboard manufacturer:
   • For laptops: go to the website Lenovo, HP, Dell etc., enter the device model and download the driver for Wireless LAN.
   • For PC: Find your motherboard model (via msinfo32 or CPU-Z) and download the driver from the manufacturer's website (ASUS, Gigabyte, MSI).
2. Wi-Fi adapter manufacturer's website:
   • Find out the adapter model (via device Manager or msinfo32).
   • Go to the website Intel, Qualcomm, Broadcom or Realtek and find the driver for your model.

Windows Update Driver Catalog:

• Open Settings → Update & Security → Windows Update → Advanced options → Optional updates.
• Check the section Driver updates — sometimes Windows itself finds suitable drivers.

After downloading the driver, install it:

1. Run the downloaded file (usually it is .exe or .msi).
2. Follow the instructions of the installation wizard.
3. Restart your computer.

If Wi-Fi doesn't work after installation, check:

• 🔌 Is the adapter included in Device Manager (right click → Engage).
• 🔄 Does the new driver conflict with other programs (for example, VPN or antivirus).
• 📡 Is the router working (try connecting from another device).

⚠️ Attention: If you are installing the driver on a laptop with Windows pre-installed (e.g. Dell XPS or HP Spectre), download the driver from the laptop manufacturer's website, not the adapter's. Manufacturers often modify standard drivers for their devices.

Common mistakes and their solutions

Even after installing the drivers, Wi-Fi may not work. Here typical mistakes and ways to eliminate them:

Error	Cause	Solution
Code 10: The device cannot start.	Driver conflict or file corruption	Uninstall the driver in Device Manager and reinstall it.
