How to determine which Wi-Fi driver is needed for your computer or laptop

A lost Wi-Fi connection, slow internet, or a complete lack of available networks are common symptoms of a problem with your wireless adapter driver. But before downloading the first driver you come across from a dubious website, you should accurately determine the model of your Wi-Fi moduleA wrong choice can lead to even more serious problems, from a drop in speed to a "blue screen of death."

In this article we will look at 5 reliable ways Find out which driver your computer needs - from standard Windows tools to specialized utilities like HWiNFO or AIDA64We'll pay special attention to cases where the adapter isn't recognized by the system at all (displayed as "Unknown Device" in Device Manager). You'll also learn how recognize fake drivers and where it is safe to download official versions.

Why is it important to know the exact model of your Wi-Fi adapter?

A driver is a "translator" between the hardware and the operating system. If it's chosen incorrectly, the consequences can be varied:

• 🔌 No network: Windows simply does not see the Wi-Fi adapter in the list of devices.
• 🐢 Speed ​​drop: there is a connection, but pages load 10 times slower than via cable.
• 🔄 Constant breaks: the router "disappears" from the list every 5 minutes.
• 💥 System failures: BSOD (blue screen) with errors like DRIVER_IRQL_NOT_LESS_OR_EQUAL.

Manufacturers produce hundreds of Wi-Fi module models even within a single line. For example, Intel There is AX200, AX201, AX210 — all support Wi-Fi 6, but require different drivers. And adapters from Realtek or Broadcom often conflict with universal Windows drivers.

⚠️ Attention: If you install a driver from another model of the same manufacturer (for example, for Intel 8265 instead of Intel 8260), the adapter may not work correctly, even to the point of being unable to connect to encrypted networks. WPA3.

Method 1: Identifying the model via Device Manager

The simplest method is to use Windows' built-in tools. This works if the adapter is recognized by the system (even if it's not working properly).

1. Click Win + X and select device Manager.
2. Expand the section Network adapters.
3. Find the device with the words Wireless, Wi-Fi, 802.11 or the name of the manufacturer (Intel, Qualcomm Atheros, Realtek etc.).

Example of correct display:

Intel(R) Wi-Fi 6 AX200 160MHz

If the name contains numbers and letters (for example, AX200, AC 9260, RTL8821CE) — this is the model of your adapter. Write it down in full, including prefixes like DW (at Dell) or BCM (at Broadcom).

⚠️ Note: Sometimes the Device Manager displays the driver name instead of the adapter model (for example, "Microsoft Wi-Fi Direct Virtual Adapter"). In this case, proceed to Method 2.

Check the "Other devices" section for "Unknown device"|

Update the hardware configuration (button "Action → Update configuration")|

Restart your computer - sometimes the adapter is detected after reboot|

Try connecting an external Wi-Fi adapter (if it's a laptop, check the wireless switch)

Method 2: Using the hardware ID (if the adapter is not recognized)

When the Wi-Fi module is displayed as "Unknown device" or is completely absent from the Manager, it will help hardware identifier (Hardware ID)This is a unique code that can be used to find the exact model.

1. In the Device Manager, find the section Other devices and open it.
2. Right-click on "Unknown Device" → Properties → tab Intelligence.
3. From the drop-down menu, select Equipment ID.
4. Copy the first line from the list (it looks like this PCI\VEN_8086&DEV_2723).

Now go to the website PCI Database or Device Hunt, paste the copied code into the search. The service will show the manufacturer and model of your adapter.

Method 3: Using the Command Prompt (for advanced users)

If you prefer to work with the console, you can find out the adapter model through command line or PowerShellThis method works even without the Internet.

Open Command line as administrator and run:

wmic nic where"NetConnectionStatus=2" get Name, Manufacturer, MACAddress, Speed

For more detailed information (including hardware ID):

wmic nic get Name, DeviceID, Manufacturer, PNPDeviceID

In the results, look for lines mentioning Wireless or manufacturer names. Parameter PNPDeviceID contains the same hardware ID as in Method 2.

Method 4: Specialized utilities (HWiNFO, AIDA64, Speccy)

Third-party programs provide the most comprehensive hardware information, including hidden adapter parameters. Let's look at three popular tools:

• 🔧 HWiNFO (free): shows exact model, supported standards (Wi-Fi 4/5/6), maximum speed and even chip temperature.
• 📊 AIDA64 (paid, but trial available): provides structured data, including the current driver version.
• 🖥️ Speccy (from the CCleaner developers): simple interface, but less detailed information.
