How to identify your Wi-Fi adapter model in Windows 7

Before you look for a driver, you need to know exactly What wireless module? installed on your device. In Windows 7, there are several ways to do this—even without an internet connection.

The most reliable method is to use device ManagerOpen it through Start → Control Panel → System and Security → Device Manager (or click Win + R, enter devmgmt.msc and press Enter). Find the section in the list Network adaptersIf the Wi-Fi module is detected as at least an "unknown device," it will be displayed here with a yellow exclamation mark.

• 🔍 Equipment ID: Right click on the unknown device, select Properties → Details → Hardware ID. Copy the first line from the list (starts with PCI\VEN_ or USB\VID_) is the unique code of your adapter.
• 📋 Model name: If the adapter is defined as Broadcom 802.11n, Intel Wireless-N 7260 or something similar—write down the full name. This will make finding the driver much easier.
• 🖥️ System information: Click Win + R, enter msinfo32. In the section Components → Network → Adapter The model may be displayed even if it is not in the Device Manager.

If the adapter is not displayed at all (for example, after a clean installation of Windows), try physically inspecting the device:

• 💻 On laptops The Wi-Fi module is usually located under a cover on the bottom panel (look for a sticker with the inscription Wireless or logo Intel/Qualcomm).
• 🖧 On stationary PCs The adapter can be built into the motherboard (check its model) or connected as a separate PCI/USB card.

⚠️ Attention: If Device Manager displays Network controller with an error Code 28, this means that the driver is completely missing. In this case, the hardware identifier (VEN_ And DEV_) is your only key to finding software.
