When a laptop suddenly stops detecting wireless networks or the connection speed drops to zero, it often leaves users perplexed. In most cases, the root of the problem lies in the software controlling the network adapter. To troubleshoot the issue, it's necessary to accurately identify the installed component and its current version. Driver — is the link between the operating system and the hardware, and without the correct operation of this software, full access to the Internet is impossible.
There are several proven ways to obtain comprehensive information about a network module without resorting to complex utilities. We'll cover standard Windows tools, command line options, and specialized tools that will help you accurately identify the device model. Understanding which one exactly Having the controller installed in your system will be the first step towards a stable connection.
Using Device Manager to Identify
The most reliable and detailed way to find information about your adapter is to use System Manager. This tool provides access to all hardware components installed in your system. To get started, press the following key combination: Win + X and select "Device Manager" from the menu that appears. You can also enter "devmgmt.msc" in the Start menu search bar.
In the window that opens, find the "Network Adapters" section and expand it. A list of all network interfaces will be displayed. The item you're looking for usually contains the words Wireless, WiFi, 802.11 or names of chip manufacturers such as Intel, Realtek, Qualcomm AtherosDouble-clicking on the device will open a properties window, where the "General" tab displays the operating status, and the "Driver" tab displays key data.
⚠️ Attention: If you see a device with a yellow exclamation point or the "Unknown Device" entry in the list of network adapters, this means the driver is corrupted or missing. In this case, the system cannot correctly identify the model, and you will need to manually install the software from a disc or another computer.
On the "Driver" tab, you'll find the "Manufacturer," "Development Date," and "Version" fields. This information is necessary for searching for updates on the manufacturer's website. Write down or copy this information to use when searching online. Knowing the exact version helps you avoid installing incompatible software, which can lead to network instability.
☑️ Check in Device Manager
Getting information via the command line
For users who prefer a text-based interface or don't have access to a graphical menu, the command line is ideal. This method allows you to quickly list all network interfaces with detailed technical information. Launch the command line as administrator by entering cmd in the search and selecting the appropriate item.
To get data, enter the command netsh wlan show driversThis command will display a detailed report specifically about the wireless network driver. The list of parameters includes "Vendor Name," "Date," "Version," and "Type." This approach is especially useful when you need to quickly copy data or save it to a log file for further analysis.
netsh wlan show drivers
An alternative option is to use a utility ipconfig /allAlthough it primarily displays IP addresses, the physical name of the adapter is often listed first, which helps identify the chip manufacturer. However, to obtain the software version, the method netsh is more informative and targeted.
What to do if the command fails?
If the system reports that the command was not found, check if the WLAN AutoConfig service is running. Without it, wireless network management is impossible, and commands may not work correctly.
Analysis via the system and PowerShell
Modern versions of Windows 10 and 11 offer advanced management capabilities through PowerShell, which is a more powerful tool than the standard command prompt. To get information about network adapters, launch PowerShell and enter the command Get-NetAdapterIt will display a table with all active interfaces, their status and speed.
For a deeper dive, you can use the command Get-PnpDevice -Class Net, which will display all devices in the network class. This allows you to see not only active adapters, but also hidden or disabled ones. The "FriendlyName" column often contains the full model name, including the chipset designation, for example, Intel(R) Wi-Fi 6 AX200.
Using PowerShell is especially useful for system administrators or advanced users who need to automate data collection from multiple machines. Scripts allow you to export information to a CSV file for subsequent comparison of software versions on different laptops in the office.
Software and utilities
If the built-in Windows tools seem too complicated or don't provide the full picture, specialized programs can help. Utilities like CPU-Z, AIDA64 or HWiNFO They collect comprehensive information about all computer components, including network cards. They display not only the driver version but also the chip revision, which is sometimes critical.
Programs for automatic driver updates, such as DriverPack Solution or Snappy Driver InstallerThey scan the system, identify missing or outdated components, and offer to install them. However, caution should be exercised: such programs may install unnecessary software or change system settings without the user's knowledge.
The safest software method is to use official software from the laptop manufacturer. Dell SupportAssist, HP Support Assistant, Lenovo Vantage or MyASUS Automatically detect the device model and find the drivers that have been tested by our engineers. This guarantees maximum stability for the WiFi module.
Table of popular WiFi chipsets and their identifiers
When searching for drivers online, you often need to know not only the device name but also its hardware ID. This is a unique code assigned by the chip manufacturer. Knowing this code, you can find a driver even for a very old or rare laptop, even when official links no longer work.
The table below provides examples of common manufacturers and the characteristic features of their equipment to help you navigate the list of devices.
| Manufacturer | Characteristic words in the title | Example of equipment ID | Typical series |
|---|---|---|---|
| Intel | Intel(R) Wireless, Centrino | VEN_8086&DEV_... | AX200, AC9560, 7260 |
| Realtek | Realtek RTL88xx, Wireless LAN | VEN_10EC&DEV_... | RTL8821CE, RTL8723DE |
| Qualcomm Atheros | QCA, Atheros | VEN_168C&DEV_... | AR9565, QCA6174 |
| Broadcom | Broadcom 802.11 | VEN_14E4&DEV_... | BCM43xx, BCM943xx |
To find your device ID, open Device Manager, go to Adapter Properties, then the Details tab. Select Hardware ID from the drop-down list. The copied string will help you find the required file in the global driver database.
Where to look and how to update software
Once you've determined the exact model and version, the next step is downloading. Priority #1 is the laptop manufacturer's official website (HP, ASUS, Acer, Lenovo). The "Support" or "Drivers" section for your device model always contains the most stable version, tested for compatibility with your specific motherboard.
The second option is the chip manufacturer's website (Intel, Realtek). The versions there may be newer, but they are universal. Sometimes this solves problems that couldn't be resolved with standard tools, but in rare cases it can cause conflicts with proprietary features of the laptop.
When installing a new driver, we recommend uninstalling the old one first. In the device properties window, on the "Driver" tab, click "Uninstall device" and check "Delete the driver software." After rebooting, the system will either automatically find the default driver, or you can install the downloaded one manually.
⚠️ Attention: Manufacturers' website interfaces and driver structures may vary. If you can't find the version you need on the support page, check the exact laptop model name (indicated on the sticker at the bottom) and try searching for the full adapter name in Device Manager.
Frequently Asked Questions (FAQ)
Is it possible to find out the WiFi driver if there is no internet at all?
Yes, you can. All the methods described (Device Manager, command line) work locally and don't require a network connection. They read information already stored in the system, even if the driver itself isn't working correctly.
What does error code 43 mean in device manager?
This code indicates that the device has reported a problem. This often indicates a software error in the driver, which can be fixed by reinstalling it, or a physical fault in the WiFi module itself.
