How to Check if Wi-Fi Drivers Are Installed: A Complete Guide for Windows

You turned on your laptop or PC, but the Wi-Fi isn't working? Or is the network icon crossed out with a red cross? The first thing to check is... Are the drivers installed on the Wi-Fi adapter?Without them, Windows simply doesn't "see" the wireless module, and all attempts to connect to the network result in an error. In this article, we'll look at 5 reliable ways diagnostics - from standard Windows tools to the command line and third-party utilities.

Wi-Fi driver issues can occur after a system reinstall, a Windows update, or even after a normal PC shutdown. Sometimes, a driver crashes due to a conflict with other software or a virus attack. We won't limit ourselves to superficial advice like "restart your computer"—instead, we'll show you how How to accurately determine the driver's status, even if the adapter doesn't appear in the list of devices. At the end of the article, you'll find an FAQ with answers to the most frequently asked questions on this topic.

1. Checking via Device Manager is the basic method

The easiest way to find out if the Wi-Fi driver is installed is to look in device ManagerThis tool displays all connected PC components and their status. If the following icon is lit next to the adapter name, exclamation mark, this means the driver is either missing or not working properly.

How to open device Manager:

• 🔹 Click Win + X and select the item device Manager.
• 🔹 Or enter the phrase in Windows search device Manager and open the application.
• 🔹 In older versions of Windows, you can use the command devmgmt.msc (enter it in the menu Execute, which opens at Win + R).

In the window that opens, find the section Network adaptersYour Wi-Fi module should be displayed here. The names may vary, but usually contain the words Wireless, Wi-Fi, Network Adapter or the manufacturer's abbreviation (Intel, Qualcomm Atheros, Realtek, Broadcom). If the section Network adapters empty or adapter is not in the list - the driver is either not installed or the device is disabled in the BIOS.

⚠️ Attention: If in Device Manager an unknown device with a yellow triangle is displayed (for example, Network controller or PCI Device), this almost always means that Windows was unable to automatically select a driver for the Wi-Fi adapter.

2. Command line: quick diagnostics without a graphical interface

If you don't have access to the graphical interface (for example, due to a system crash) or you prefer to work with commands, you can check the drivers via Command line (CMD). This method is also suitable for remote diagnostics (for example, by RDP or TeamViewer).

Open Command line as administrator (click Win + X → Terminal (Administrator)) and enter two commands in sequence:

netsh wlan show drivers
driverquery | find "Wi-Fi"

First team (netsh wlan show drivers) will display information about the Wi-Fi driver, if installed. Note the following lines:

• 🔹 Radio type — must be specified 802.11n, 802.11ac or 802.11ax (Wi-Fi standards).
• 🔹 Hosted network support - If Yes, the adapter can operate in access point mode.
• 🔹 Driver name — here will be the name of the driver file (for example, netwsw00.inf For Intel).

Second team (driverquery) will display a list of all installed drivers. If the results don't include Wi-Fi or the name of your adapter, the driver is missing.

3. Checking via System Information (msinfo32)

Tool System Information (msinfo32) collects detailed information about your PC's configuration, including data about network adapters and their drivers. This method is useful if you need technical details - for example, driver version, release date or device identifiers (PCI\VEN).

How to open:

1. Click Win + R, enter msinfo32 and press Enter.
2. In the left part of the window, go to the section Components → Network → Adapter.
3. On the right side, find your Wi-Fi adapter (by name or by word) Wireless).

Please pay attention to the following fields:

If in the field State indicated Driver missing or Unknown device, then the driver isn't installed. In this case, you'll need to download it from the laptop or adapter manufacturer's website.

4. Diagnostics via "Network Connections"

Another way to check the Wi-Fi driver's functionality is to look at the list of network connections. If the adapter is working correctly, an item should appear here. Wireless network (or Wi-Fi). If it is not there, the problem is either in the driver or in the module itself.

How to open Network connections:

• 🔹 Click Win + R, enter ncpa.cpl and press Enter.
• 🔹 Or open Windows Settings → Network and Internet → State → Changing adapter settings.

In the window that opens, please note the following:

• 🔹 If the icon Wireless network gray and signed as The network is disconnected — the adapter is turned off (possibly by a button on the laptop case or in the BIOS).
• 🔹 If there is no icon at all, the driver is not installed or the adapter is not recognized by the system.
• 🔹 If the icon is there, but there is a red cross next to it, check if Wi-Fi is enabled on the adapter itself (sometimes you need to press Fn + F2 or another combination).

⚠️ Note: On some laptops (e.g. Lenovo or HP) The Wi-Fi adapter can be disabled using a hardware button or in the manufacturer's utility (for example, Lenovo Vantage or HP Support Assistant). Before checking the drivers, make sure that the adapter is not blocked at the BIOS or firmware level.

5. Checking using third-party utilities (AIDA64, Driver Booster)

If standard Windows tools don't provide a complete picture, you can use third-party programs. They will not only show whether a driver is installed but also help you update it or find a replacement. The most popular utilities are:

• 🔹 AIDA64 - shows detailed information about the equipment, including device identifiers (PCI VEN/DEV).
• 🔹 Driver Booster — scans the system for outdated or missing drivers.
• 🔹 HWiNFO — a free utility for diagnosing PC hardware.

Let's look at the verification using an example AIDA64:

1. Download and install the program from official website.
2. Open the section Devices → Windows Devices.
3. Find your Wi-Fi adapter in the list. If there's a warning icon next to it, the driver isn't working properly.
4. Go to the section Summary → DMI → Network Adaptersto see technical details (eg MAC address or PCI ID).

Advantage AIDA64 in what she shows equipment identifiers (VEN_XXXX And DEV_XXXX), which can be used to search for a driver on sites like DevID.infoThis is especially useful if Windows does not recognize the adapter as a network device.

How to find a driver by PCI ID?

If in AIDA64 or Device Manager you see a line like this PCI\VEN_168C&DEV_003E, copy it and enter it on the website DevID.infoThe system will select the appropriate drivers for your adapter. This method works even if Windows identifies the device as "Unknown."

6. Checking via BIOS/UEFI - if the adapter is not detected at all

If none of the above methods showed the presence of a Wi-Fi adapter, it may be disabled at the BIOS/UEFI levelThis often happens after resetting the BIOS settings, updating the firmware, or if someone manually changed the settings.

How to check:

1. Restart your PC and enter BIOS/UEFI (usually you need to press Del, F2, F12 or Esc when loading).
2. Find the section Advanced, System Configuration or Onboard Devices Configuration (names depend on the motherboard manufacturer).
3. Look for settings related to Wi-Fi or Wireless:
   • 🔹 Wireless LAN - must be in position Enabled.
   • 🔹 WLAN or Wi-Fi Adapter — included (On).
   • 🔹 PCIe/PCI Subsystem Settings - sometimes the adapter is disabled here.

Save changes (F10) and restart your PC.

If the adapter was disabled in the BIOS, Windows should automatically install the driver (if it's included in the system database) after enabling it. If this doesn't happen, download the driver from the laptop or motherboard manufacturer's website.

⚠️ Note: On some laptops (e.g. Dell Latitude or HP EliteBook) The Wi-Fi adapter can be disabled through WHQL certification in the BIOS. In this case, enabling it will require resetting the BIOS to factory settings or updating the firmware.

FAQ: Frequently asked questions about checking Wi-Fi drivers

My Wi-Fi adapter is identified as a "Network Controller" with an exclamation mark. What should I do?

This means that Windows recognizes the device as a network device, but can't find a driver for it. You need to:

1. Find Equipment ID (V Device Manager → device properties → tab Intelligence → Equipment ID).
2. Copy a line of the form PCI\VEN_XXXX&DEV_XXXX.
3. Enter it on the website DevID.info or PCIDatabaseto find the driver.

If the adapter is built-in (for example, in a laptop), the driver can be downloaded from the model manufacturer’s website (for example, ASUS, Lenovo).

Wi-Fi stopped working after a Windows update. What's wrong?

Most often this happens because Windows has automatically installed incompatible or outdated driverSolutions:

• 🔹 Roll back the driver Device Manager (right click on the adapter → Properties → Driver → Roll back).
• 🔹 Download the latest driver from the manufacturer's website and install it manually.
• 🔹 Disable automatic driver updates via Windows Settings → Updates and Security → Additional options → Driver updates.

How can I find out the model of my Wi-Fi adapter if it is not detected by the system?

If the adapter is not displayed in any Device Manager, not in msinfo32, try:

• 🔹 View the documentation for your laptop or motherboard (on the manufacturer's website).
• 🔹 Disassemble the laptop and look at the markings on the adapter itself (usually this is a sticker with the model name).
• 🔹 Use a Linux LiveCD (for example, Ubuntu) - some distributions detect hardware better than Windows.

For PC: If the adapter is external (USB or PCIe), the model is usually indicated on the device body.

Is it possible to use Wi-Fi without drivers?

No. A driver is software that allows the operating system to communicate with the hardware. Without a driver, a Wi-Fi adapter is just a piece of plastic and metal that Windows can't use. The exception is that some adapters support universal drivers (For example, Realtek RTL8188EU may work with a driver from another model), but this does not guarantee stable operation.

After reinstalling Windows, Wi-Fi isn't working. What should I do?

This is a common situation—Windows doesn't always automatically install drivers for Wi-Fi adapters. Here's what you can do:

1. Connect your PC to the Internet via cable (Ethernet) or USB modem.
2. Download the driver from the laptop/motherboard manufacturer's website (section Support or Drivers).
3. If you don't have access to another internet connection, download the driver on another device and transfer it to a flash drive.
4. Install the driver and restart your PC.

For laptops Lenovo, HP, Dell And ASUS There are proprietary utilities for automatic installation of drivers (for example, Lenovo System Update or HP Support Assistant).
