The stability of a wireless connection directly depends on the correct operation of the software components that control the network adapter. When internet speeds drop and the network icon disappears, the first thing to do is check the drivers in Windows 10. This is a basic step that is often overlooked, even though it is the software that ensures proper communication between the operating system and the physical Wi-Fi module.
In most cases, problems arise after a major system update or installation of new hardware. Device driver It may be outdated, corrupted, or simply conflict with new security protocols. Knowing how to check its status will save you hours of waiting for pages to load or rebooting your router.
There are several diagnostic methods, from simple built-in tools to specialized software. We'll cover each one so you can choose the most appropriate one for your situation. The key is to follow a consistent approach to rule out software failures.
⚠️ Note: The Device Manager interface and settings menu may differ slightly depending on the Windows 10 build (versions 21H2, 22H2, and later), but the operating logic remains the same.
Device Manager: Initial Diagnostics
The fastest way to check the hardware status is to use the standard system tool. Press the key combination Win + X and select "Device Manager" from the menu. In the window that opens, find the section Network adapters and unfold it.
All network interfaces, including virtual ones, are displayed here. You need a physical adapter, which often contains the words Wireless, Wi-Fi, 802.11 or brands like Intel, Realtek, QualcommIf a yellow triangle with an exclamation point appears next to the device icon, this means the driver is not working correctly or is missing.
Double-click the adapter name to open its properties. On the "General" tab, the "Device Status" field will display the error code, if any. Codes 10 or 43 often indicate that the device cannot start. In this case, checking drivers becomes critically important.
- ✅ Green arrow or no icons - the device is working properly.
- ⚠️ Yellow triangle — resource conflict or software corruption.
- ❌ Red cross — the device is disabled or physically faulty.
- 🔍 Invisible device - the adapter may be disabled in the BIOS or has failed.
If you see a device with an unknown ID, try clicking the "Remove Device" button and then selecting "Action" -> "Update Hardware Configuration" from the top menu. The system will attempt to reinitialize the module.
Using the command line for detailed analysis
For a more in-depth check of the condition network card You can use the command line to access the software. This method provides more technical information than the graphical interface. Launch the terminal as administrator by entering cmd in the search and selecting the appropriate item.
Enter the command netsh wlan show drivers and press Enter. The system will display a detailed report on the current Wi-Fi driver. The information you're interested in is the section that lists the manufacturer, version, and date.
C:\Users\User> netsh wlan show drivers
Wi-Fi Driver Information
Interface name: Wi-Fi
Driver status: Driver is running.
Driver Provider: Microsoft Corporation
Driver date: June 21, 2006
Driver version: 10.0.19041.1
Pay attention to the date. If the driver is several years old and you just updated Windows, this may be the cause of the problem. The output also shows the supported radio types. If your router broadcasts a 5 GHz network, but the driver only supports 802.11n (2.4 GHz), you won't see fast networks.
Another useful command is - ipconfig /allFind your wireless adapter in the list. If it doesn't appear in the list at all, the system isn't detecting it at the TCP/IP protocol level, which often indicates a critical driver error.
Automatic updating via Windows Update
Windows 10 has a powerful update search engine that often finds the necessary drivers automatically. However, sometimes the files you need are hidden in the optional updates section. Go to Start → Settings → Update & Security.
Click the "Check for Updates" button. If the system finds critical fixes for your hardware, it will install them automatically. But before you close the window, look for the "View optional updates" link.
Drivers for are often found within this section. Wi-Fi adapters, which Microsoft doesn't force, but offers to the user. Select the desired device from the list and click "Download and Install."
- 🔄 Click "Check for updates" in the main window.
- 📂 Go to "View optional updates" → "Driver updates".
- 📥 Check the box next to your wireless adapter.
- 🚀 Run the installation and wait for the reboot.
This method is the safest, as all drivers in the Microsoft database are certified for stability. The risk of getting malware or an incompatible version is minimal.
Manual installation from the manufacturer's website
If standard methods fail, you'll have to resort to manual methods. This is the most reliable way to get the latest software version, especially for gaming laptops or specific USB adapters. You'll need to know the exact model of your laptop or motherboard.
Go to the support section of the manufacturer's official website (ASUS, HP, Lenovo, Dell, etc.). Enter the device's serial number or select the model from the list. Find the "Drivers" or "Support" section and select your OS version.
Download the file marked as Wireless LAN, WiFi Driver or NetworkPlease note that a single laptop may have multiple WiFi module options (for example, Intel and Realtek). Download the driver that matches your hardware, or download both if you're unsure.
⚠️ Warning: Never download drivers from dubious aggregator websites. Use only official resources from hardware manufacturers or Microsoft.
After downloading, run the installer. Your screen may go blank during the installation process—this is normal. Once complete, be sure to restart your computer for the changes to take effect.

Comparing versions and rolling back the system
There are times when a new driver version performs worse than the old one. In this case, it might be worth rolling back. In Device Manager, go to the adapter properties and select the "Driver" tab. If the "Roll Back" button is active, you can revert to the previous version.
To compare versions, it's helpful to use a table that compares current and required settings. This will help you understand whether you need an upgrade or a downgrade.
| Parameter | Current value | Required/Optimal | Status |
|---|---|---|---|
| Driver version | 22.0.0.5 | 22.10.0.1+ | Update required |
| Release date | 2021-05-10 | 2026-11-20 | Outdated |
| Security protocol | WPA2-Personal | WPA3-SAE | It is advisable to update |
| Wi-Fi standard | 802.11ac | 802.11ax (Wi-Fi 6) | Depends on the router |
If a restore through the task manager isn't possible, you can use system restore points. Search for "Restore" and choose to create a restore point or restore the system to an earlier date when Wi-Fi was working properly.
It is important to understand that driver rollback may temporarily solve the problem, but in the long run it is better to find a compatible new version that fixes the security vulnerabilities.
What to do if the undo button is inactive?
If the system reports that there is no restore point, try completely removing the device from the device manager (with the "delete driver software" checkbox checked), rebooting, and allowing Windows to reinstall the basic driver.
Diagnostics using third-party utilities
When Windows 10's built-in tools fail, specialized programs come to the rescue. Utilities like Driver Booster, Snappy Driver Installer or DriverPack Solution scan the system and find drivers.
Using such programs is convenient because they have huge databases. However, be careful: many of them offer additional unnecessary software (browsers, antiviruses) during installation. Carefully uncheck any unnecessary offers.
The safest option is to use utilities from the chipset manufacturer, for example, Intel Driver & Support AssistantThis program automatically detects your WiFi module model and offers the latest version from the Intel website, ignoring custom versions from the laptop manufacturer, which are often outdated.
- 🔍 Scanning takes 1-2 minutes.
- 📥 Downloads are made from official servers.
- ⚙️ Automatic installation without user intervention.
- 📊 Report on all obsolete PC components.
After using any snail, be sure to test your network. If the speed hasn't improved and the ping remains high, the problem may not be with the driver, but with the router settings or physical damage to the antenna.
Frequently Asked Questions (FAQ)
