How to determine the model and specifications of your laptop's Wi-Fi adapter

Wireless internet connections have become standard in today's world, but users often encounter situations where their laptop stops detecting networks or the connection speed drops to critical levels. The first step in resolving these issues is accurately identifying the device's installed hardware. Wi-Fi moduleKnowing the specific adapter model allows you to find the latest drivers, check its compatibility with new communication standards, and eliminate hardware conflicts.

Many people mistakenly believe that it is enough to know only the brand of the laptop, but inside models with the same name, completely different components can be installed network controllers from manufacturers like Intel, Realtek, or Qualcomm Atheros. Determining the exact specification is necessary for proper configuration of the 2.4 GHz and 5 GHz frequency bands, as well as to determine whether your device supports the latest protocol. Wi-Fi 6 (802.11ax)Without this information, any attempts to optimize the network may be futile.

Using Windows Device Manager

The fastest and most accessible way to get information about your network equipment is using the operating system's built-in system tool. You don't need to install any third-party software; administrator rights are sufficient. Open the Start menu and search for devmgmt.msc and press Enter, or right-click on the Start button and select Device Manager.

In the window that opens, find the "Network Adapters" section and expand it. This will display a complete list of all network interfaces, including virtual and physical ones. Look for the line containing the words Wireless, Wi-Fi or 802.11This is where the exact name of the chip is indicated, for example, Intel(R) Wi-Fi 6 AX200 or Realtek RTL8822BE.

⚠️ Note: If you see a device with a yellow exclamation point or the words "Unknown Device" in the list, this means the driver is not installed or is not working correctly. In this case, the model may be displayed as "Network Controller" without specifying the brand.

For more detailed information, double-click the adapter name to open its properties. In the "General" tab, you'll see the device status, and in the "Driver" tab, you'll see the version and date of the installed software. This is critical when searching for updates on the manufacturer's website.

Defining the adapter via the Command Line

If the graphical interface doesn't provide the full picture, the command line comes to the rescue. This method allows you to get a structured report on the wireless network status without having to delve into the depths of system menus. Press the key combination Win + R, enter cmd and press Enter.

In the black terminal window, enter the command netsh wlan show drivers and press Enter. The system will display a detailed report about the wireless driver. At the top of the report, you'll find the "Driver Name" and "Provider" lines, as well as important information about supported radio types.

netsh wlan show drivers

Pay attention to the "Supported Radio Types" line. This will indicate whether your adapter only works in the 2.4 GHz band or whether it supports both. dual-band mode (2.4 GHz and 5 GHz). The maximum receive and transmit speeds are also displayed here, which helps you understand the theoretical speed limit of your connection.

What does "Radio Type 802.11ac" mean? This means your adapter supports the Wi-Fi 5 standard, which operates primarily in the 5 GHz band and provides fast speeds but requires a compatible router.

Additionally, you can use the command ipconfig /all, which will show the physical address (MAC address) of the adapter and its current network status. Although the model name won't be listed, the presence of an entry for the wireless adapter confirms that the system at least sees the device.

Search by VEN and DEV code (equipment ID)

When drivers aren't installed and Device Manager displays an "Unknown Device," unique hardware identifiers can help. Each network controller has a vendor (VEN) and device (DEV) ID, which can be used to accurately identify the model, even without its name.

In Device Manager, right-click the unknown device and select "Properties." Go to the "Details" tab and select "Hardware IDs" from the drop-down list. You'll see lines like PCI\VEN_8086&DEV_2723. Here VEN_8086 indicates the manufacturer (in this case Intel), and DEV_2723 — for a specific chip model.

  • 🔍 Copy the value of the first line of the Hardware ID.
  • 🌐 Enter it into a search engine (Google or Yandex).
  • 📥 Find the manufacturer's website or driver database using this code.
  • 💾 Download and install the appropriate driver for your version of Windows.

This method is most reliable for older laptops or rare models where automatic driver installation via Windows Update fails. Knowing the exact code will eliminate the risk of installing incompatible software, which could lead to network instability.
