It often catches you by surprise when a laptop or desktop PC with a wireless module stops detecting your home network. The screen may show no available connections, or the list of networks may be empty, even though the router is working properly. This is a common problem in Windows 10 and 11, which can be caused by either a software failure or physical damage to the hardware.
Before panicking, it's worth understanding that Microsoft's operating system has a complex network adapter management structure. Sometimes the problem occurs at the service level, sometimes updated drivers are to blame, and in rare cases, power saving settings. Your task — consistently eliminate each of the possible causes, moving from simple checks to complex settings.
In this guide, we'll cover specific steps to restore internet access without calling a technician. We'll cover hardware diagnostics, working with Device Manager, and using the command line to reset network settings.
Initial diagnostics and physical connection check
The very first step, often overlooked by users, is a visual check of the indicators. If your computer can't detect the router via Wi-Fi, make sure the light with the wireless network symbol (usually the antenna) on the router itself is lit or blinking. If there's no indicator light, it could mean the router's Wi-Fi module is disabled or the device is frozen.
It's also worth checking whether the wireless module itself is enabled on your computer. On many laptops Lenovo, Asus or HP There's a physical switch on the case or a key combination (e.g., Fn + F2) that disables the adapter software-based. If the module is disabled "hardware-based" or via a software key, no Windows settings will help.
⚠️ Attention: If you're using a USB Wi-Fi adapter, try plugging it into a different port. Ports on the front panel of the system unit often have poorer contact and lower voltage than ports on the rear of the motherboard.
It's a good idea to reboot your router. Simply turning the power off for 10-15 seconds will clear the device's memory buffer and resolve any temporary DHCP server errors. After turning it back on, wait 2-3 minutes for the system to fully boot up, and then check the list of available networks again.
Checking the adapter status in Device Manager
If the physical indicators are normal, but the computer still doesn't see the router, you need to check how the operating system sees the network adapter itself. To do this, press the combination Win + X and select from the menu device ManagerIn the window that opens, find the section Network adapters and open it.
Here you should be interested in a device with a name containing the words "Wireless", "Wi-Fi", "802.11" or brands like Intel, Realtek, QualcommIf a yellow exclamation point appears next to a device, it indicates a driver error or resource conflict. If the adapter is displayed as "Unknown Device," the system cannot identify it.
Try right-clicking on the adapter and selecting "Uninstall device." Don't worry, it's safe. After uninstalling, select "Uninstall Device" from the top menu. Action → Update hardware configurationWindows will attempt to redetect the hardware and install the standard driver, which often resolves the issue.
Reset network settings via command line
Often, the cause lies in accumulated TCP/IP protocol errors or incorrect DNS cache settings. Built-in Windows tools allow you to perform a deep reset of network settings. To do this, run the command prompt as an administrator. Click Win + S, enter cmd, then right-click on "Command Prompt" and select Run as administrator.
In the window that opens, you need to enter a series of commands sequentially by pressing Enter after each one. These commands will flush the DNS cache, renew the IP address, and clear Winsock settings.
netsh winsock resetnetsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns
After running the last command, be sure to restart your computer. This method is especially effective if the computer sees other networks but doesn't detect your home network, or if the connection status changes to "No Internet Access."
☑️ Network Reset Checklist
Setting up the WLAN AutoConfig service
A special system service in Windows is responsible for detecting wireless networks. If it is stopped or its startup type is changed, the computer will be physically unable to scan the air. To check its status, click Win + R, enter services.msc and press Enter.
In the list of services, find WLAN AutoConfig (In some versions of Windows, it may be called "WLAN AutoConfig Service"). Double-click it. Make sure the "Startup type" field is set to AutomaticallyIf the service status is "Stopped", click the button Launch.
| Parameter | Recommended value | Error Action |
|---|---|---|
| Launch type | Automatically | Select from the list |
| State | In progress | Click "Start" |
| Dependencies | Connection Information Service | Check in the "Dependencies" tab |
If the service starts and then immediately stops, check the "Dependencies" tab. Another system service that the WLAN depends on may not be running. It's also worth checking your system for viruses, as malware often blocks network services.
What to do if the service does not start?
If the WLAN AutoConfig service fails to start and returns an error (e.g., code 1068), try starting dependent services. Starting the Network Connection Awareness Service (NlaSvc) and Remote Access Connection Manager services often helps.
Wi-Fi adapter power management
Windows, especially on laptops, tries to conserve power and may disable the Wi-Fi adapter, considering it unused. This results in the computer no longer seeing the router after waking from sleep mode. To prevent the system from disabling the adapter, return to device Manager.
Find your wireless adapter, open its properties (double click) and go to the tab Power managementUncheck the box next to "Allow the computer to turn off this device to save power."
This action will force the adapter to run in constant mode, which may slightly increase battery drain on laptops, but will ensure a stable connection. After applying the settings, restart your computer and check for network availability.
Radical Measures: Complete Network Reset in Windows
If none of the above methods help, Windows offers a full network reset. This will delete all saved Wi-Fi profiles, reset TCP/IP settings to factory defaults, and reinstall network adapters. This is the "heavy artillery" that solves 95% of software problems.
To perform a reset, open Parameters (gear in the Start menu), go to Network and InternetFind the link at the very bottom of the page. Network reset (in Windows 10) or button Reset now (in Windows 11).
⚠️ Attention: After resetting the network, your computer will reboot in 5 minutes. You'll have to re-enter passwords for all Wi-Fi networks, as they will be deleted from the system's memory. Remember or write down your router password in advance.
The process takes a few minutes. After rebooting, the system will reinstall the network adapters with default settings. If this doesn't help, the problem most likely lies in a hardware fault with the Wi-Fi module or in the router's settings (for example, a hidden SSID or MAC address filter).
Hidden SSID
If the router is configured as a "Hidden Network," it won't broadcast its name. In this case, the computer won't see the router in the general list. You'll need to create a new connection manually, entering the network name (SSID) and security type exactly as configured on the router.
Frequently Asked Questions (FAQ)
Why can my phone see Wi-Fi but my computer can't?
This indicates the router is working properly. The problem is localized to the computer: either the Wi-Fi adapter driver is outdated or corrupted, or the module itself is faulty. Try updating the drivers from the laptop manufacturer's website.
Can antivirus software block network visibility?
Yes, some third-party antiviruses and firewalls (such as Kaspersky or ESET) have network protection features that can block detection of new devices or networks. Try temporarily disabling your antivirus to test.
What does error code 43 mean in Device Manager?
Code 43 means that Windows has stopped this device because it has reported problems. This often indicates a physical failure of the Wi-Fi module or a serious driver conflict. A complete driver reinstallation or replacement of the adapter will help.
How do I check if my PC supports Wi-Fi?
In the command line, enter netsh wlan show driversIf the "Hosted Network Support" line says "Yes," then the adapter is present and working. If the command returns an error or states that the service is not running, then the driver is not installed or the adapter is missing.
