It is impossible to imagine a modern laptop without the ability to wirelessly connect to the global network, and this function is provided by Wi-Fi adapterUsers often need to know the exact model of a device or the version of the installed driver, especially when experiencing connection issues, low internet speeds, or after reinstalling the operating system. Understanding which one iron installed on your laptop is the first step to properly diagnosing any network problems.
Knowing the specifications of your network interface allows you to not only find the correct drivers on the manufacturer's website, but also to understand whether your equipment supports the latest communication standards, such as Wi-Fi 6 (802.11ax) or 5 GHz frequency bands. In this article, we'll examine in detail all available hardware identification methods: from built-in Windows operating system tools to specialized software and physical inspection of the board.
Adapter version information is also critical when purchasing a new router to ensure compatibility and maximize channel speeds. Let's look at where this information is hidden and how to interpret it to suit your needs.
Using Windows Device Manager
The fastest and most accessible way to obtain basic information about installed equipment is the standard device ManagerThis tool is built into all versions of Windows and doesn't require any additional software, making it ideal for initial diagnostics. To open it, right-click the Start button and select the appropriate option from the context menu, or use the keyboard shortcut. Win + X and find the section you need.
In the window that opens, find the "Network Adapters" section and expand it. This will display a complete list of all network interfaces, including wired (Ethernet) and wireless (Wi-Fi, Bluetooth). A wireless module usually has the words "wireless" in its name. Wireless, Wi-Fi, 802.11 or names of chip manufacturers such as Intel, Realtek, Qualcomm Atheros.
Double-click the name of your adapter to open the properties window. The "General" tab at the top of the window displays the full name of the device, and its status below it. This is often where you can see the driver version, but for more detailed technical information, it's best to go to the "Details" tab.
β οΈ Important: If you see a device with a yellow exclamation point or the name "Unknown Device" in the list of network adapters, this means the drivers are not installed or are not working correctly. In this case, the system may not display the actual model name.
To obtain the exact firmware version or hardware revision, go to the "Details" tab and select "Hardware ID" or "Hardware Version" from the "Property" drop-down list. These unique codes allow you to identify the device even if its name is displayed incorrectly.
Defining a model via the command line
For more experienced users who prefer working with console commands, the Windows operating system provides powerful tools through Command line (CMD) or PowerShell. This method often produces more structured output and allows you to quickly copy the information for further driver searches.
Run Command Prompt as Administrator by typing cmd in the Start menu search. To get general information about all network interfaces, enter the command netsh wlan show interfacesAs a result, you will see a detailed report, where the "Description" line will indicate the exact adapter model, and the "Radio Type" will indicate the supported standards.
If you need to get the hardware ID (Vendor ID and Device ID), which is often necessary for searching drivers on specialized forums, use the command:
wmic path win32_pnpentity where "PNPClass='Net'" get Name,DeviceID,ManufacturerThis command will list all network devices with their IDs. Find your Wi-Fi adapter in the list by manufacturer name. The combination VEN_XXXX denotes the manufacturer, and DEV_YYYY β a specific device. These codes are universal and help find drivers even for very old or rare laptop models.
βοΈ Check adapter status
Using the msinfo32 utility for detailed diagnostics
There is a hidden but extremely useful utility in the Windows operating system. msinfo32 (System Information), which collects comprehensive information about your computer's configuration. This tool is especially useful when the standard Device Manager doesn't display complete data or is experiencing errors.
To launch the utility, press the key combination Win + R, enter msinfo32 and press Enter. In the window that opens, go to the following path: Components β Network β AdapterA list of all network cards will appear in the right part of the window. Find your Wi-Fi module by name.
Here you can find parameters such as "Adapter Name," "Adapter Type," "Adapter String," and "Driver Version." Pay particular attention to the "Adapter String" field, which often indicates the exact chipset model. Information about the MAC address and current connection status is also available here.
| Parameter | Description | Where to look for meaning |
|---|---|---|
| Name | Commercial name of the device | Device Manager / Properties |
| Manufacturer | The chip developer | Adapter Properties / msinfo32 |
| Driver version | Date and software version number | Driver/Details tab |
| Radio type | Supported standard (b/g/n/ac/ax) | netsh wlan show drivers command |
Usage msinfo32 This is especially useful when preparing reports for technical support, as the data is presented in a unified format that's easy to copy and analyze. Additionally, you can see if the device is disabled by software in the BIOS.
Third-party hardware identification programs
When built-in Windows tools aren't enough, specialized third-party utilities come to the rescue. Programs like AIDA64, HWInfo, Speccy or CPU-Z are capable of reading data directly from hardware registers, providing information that the operating system has hidden.
The most popular and informative utility is AIDA64After launching the program, go to "Network" β "Windows Network" or "PCI/PnP Network." This will display the adapter's full specifications, including the chipset version, current connection speed, support for power-saving technologies, and even the module's temperature (if a sensor is available).
Another powerful tool is HWInfoWhen launching, select "Sensors-only" or "Summary" mode, then find the "Network" section. The program will display not only the model but also detailed driver information, including its release date and digital signature, which is useful for verifying software authenticity.
β οΈ Warning: Download diagnostic programs only from the official websites of the developers. Using questionable all-in-one builds may lead to the installation of adware or viruses that will disrupt network operation.
The advantage of third-party software is its ability to aggregate data: you can immediately see whether the adapter's advertised speed matches your router's actual speed. For example, if the adapter only supports 802.11n, and the router distributes Wi-Fi 6, the program will point out this βbottleneckβ.
Analyzing characteristics via PowerShell
PowerShell offers more flexible options for filtering and displaying information than the standard command line. It lets you display exactly the data you need in a convenient format. Open PowerShell and enter the command to get driver status:
Get-NetAdapter | Where-Object {$_.Status -eq 'Up'} | Select-Object Name, InterfaceDescription, DriverVersion, DriverDateThis command will filter only active adapters and display their description, driver version, and release date. This is a great way to quickly check if your network module's firmware is out of date.
To get information about supported Wi-Fi modes, you can use the command:
netsh wlan show driversIn the output of this command, look for the line "Supported radio types." It will list which standards (802.11a/b/g/n/ac/ax) your adapter supports. If there is no mention 802.11ac or ax, which means your laptop won't be able to operate in the 5 GHz band at high speeds, regardless of the router's power.
You can also use PowerShell to find out the MAC address and connection status to a specific network, which is useful when setting up MAC address filtering on a router. Command Get-NetAdapter Provides a basic summary that can be expanded with additional parameters.
Physical inspection and marking of the module
If software methods fail (for example, the adapter is burned out or not detected by the system), the only reliable method is a physical inspection. In most modern laptops, the Wi-Fi module is a small circuit board. M.2 or Mini PCIe, located under the back cover.
To access the module you need:
- βοΈ Turn off the laptop completely and disconnect the battery (if it is removable).
- π§ Unscrew the screws of the bottom cover and carefully remove it.
- π‘ Find a small board (usually 12x30mm or 16x30mm) with antenna wires (black and white) soldered on.
- π Read the markings on the metal screen of the module.
The sticker will indicate the exact model number (eg. Intel AX200, Realtek 8822CE), as well as FCC ID codes. Knowing the exact model, you can go to the manufacturer's website and download drivers, even if Windows doesn't detect the device. The sticker also often indicates the supported frequencies and power.
When inspecting, pay attention to the condition of the antenna connectors. If the wires are disconnected, the adapter will operate very erratically or not at all. When reassembling, it's important to connect the antennas correctly: the main wire is usually black, and the auxiliary wire is white, although color coding may vary between laptop models.
β οΈ Caution: Opening the laptop case may void the warranty. If the device is under warranty, it is best to contact an authorized service center to determine the adapter model.
Frequently Asked Questions (FAQ)
Why is the adapter called "Standard Wi-Fi Adapter" in Device Manager?
This means the operating system didn't recognize the exact device model and installed the standard Microsoft driver. In this case, functionality may be limited, and for full functionality, you'll need to find and install the driver from the laptop or chipset manufacturer's website using the hardware ID.
Is it possible to update the adapter (hardware) version using software?
No, the hardware version (chip revision) cannot be changed via software, as it is a physical characteristic of the chip. However, you can update the adapter's firmware if the manufacturer has released such updates. Most often, "update" simply means installing a new driver version, which improves stability and performance.
How do I know if my adapter supports 5GHz?
Run the command netsh wlan show drivers in the command line. The "Supported radio types" line should indicate the standards 802.11a, 802.11ac or 802.11ax. If only present 802.11b/g/n, then most likely the adapter only works in the 2.4 GHz range, although some N-class models may support 5 GHz, which will be indicated in the model specifications.
Where can I find a driver if I don't know the exact laptop model?
Use the hardware IDs (VEN and DEV codes) from the device properties in Device Manager. Enter these codes into a search engine (e.g., "VEN_8086 DEV_0000"), and specialized databases will suggest the exact device name. You can then find the driver on the chip manufacturer's website (Intel, Realtek, etc.).
