Reinstalling the Wi-Fi driver in Windows 10: A complete guide with solutions to common errors

Problems connecting to Wi-Fi in Windows 10 — one of the most common problems users encounter. Most often, the culprit is a malfunction. wireless adapter drivers, especially after system updates, virus attacks, or improper computer shutdowns. Reinstalling the driver is a universal way to restore network access, but many are afraid to do it themselves, fearing it will worsen the situation.

In fact, the process is no more difficult than installing a regular app, if you know the nuances. In this article, we'll break it down. all methods of reinstallation - from automatic through device Manager to manual setup from the manufacturer's official website. We'll pay special attention to situations where there's no internet connection on your PC at all, requiring you to use a second computer or mobile phone. You'll also learn how to determine the exact adapter model, where to download the correct driver, and what to do if Wi-Fi still doesn't work after reinstalling.

Before you begin, check the basics: is the adapter physically turned on (on some laptops there is a separate button or combination Fn + F2/F12), is it turned off in BIOS, and whether the router is working (try connecting another device). If everything is fine, we'll proceed to driver diagnostics.

1. How to determine the model of your Wi-Fi adapter in Windows 10

Before downloading or uninstalling a driver, you need to know exactly which one it is. wireless adapter installed on your device. This is critical: an unsuitable driver can cause conflicts or even fail to install at all. There are three reliable ways to find out the model.

The easiest way is through device Manager:

1. Click Win + X and select device Manager.
2. Expand the branch Network adapters.
3. Look for devices with names like Wireless, Wi-Fi, 802.11 or brands Intel, Qualcomm Atheros, Realtek, Broadcom.
4. Right click on it → Properties → tab Intelligence.
5. From the drop-down menu, select Equipment ID — the list will contain lines of the following type PCI\VEN_8086&DEV_24FDThese are unique manufacturer identifiers (VEN) and models (DEV).

If the adapter is displayed as Unknown device or marked with a yellow exclamation mark, use Equipment ID to search for the driver (more on that below). An alternative method is the command line:

wmic nic where "NetEnabled='true'" get Name, Manufacturer, MACAddress

This command will list all network devices, indicating their manufacturer and MAC address. For laptops, you can also find the adapter model on the manufacturer's official website by entering the device's serial number.

4. Installing the Wi-Fi driver manually

Once the driver is downloaded, all that's left to do is install it. The process depends on the file format:

• 📁 If this EXE file - Just run it and follow the installation wizard instructions.
• 📄 If this ZIP archive or a folder with files .inf, .sys, .dll - you need to install the driver through device Manager.

Step-by-step instructions for manual installation:
