And at the end of the article, you'll find answers to frequently asked questions and tips on how to avoid similar problems in the future.

1. Checking the physical connection and basic settings

Before digging deep into system settings, make sure the problem isn't hidden on the surface. Users often miss obvious issues, spending hours troubleshooting instead of checking the simplest things.

Start with physical Wi-Fi button on the laptop case (if there is one). On some models Lenovo, HP or Asus Wireless modules are disabled by a hardware switch—it's easy to accidentally trip. Also, check the indicators: if the light next to the antenna is off or blinking orange, the adapter is off.

• 🔍 Check it out Wi-Fi switch on the side panel of the laptop (often next to the USB ports).
• 🔄 On some keyboards the combination Fn + F2 (or another function key with an antenna icon) turns the module on/off.
• 🔌 If you use PCI-e Wi-Fi adapter On a desktop PC, make sure it fits snugly into the motherboard slot.
• 📡 Check if Wi-Fi works on other devices (smartphone, tablet). If not, the problem is with the router, not the computer.

If the physical connection is OK, proceed to testing Windows network settings. Open Settings → Network & Internet → Status and see if the section is active Wi-FiIf it is missing or grayed out, the adapter is disabled at the OS level.

2. Enable the Wi-Fi adapter via Device Manager

One of the most common reasons for Wi-Fi to disappear is disabling the network adapter in the Device Manager. This can happen after a system update, a driver conflict, or even a virus. To check the adapter's status:

1. Click Win + X and select device Manager.
2. Expand the tab Network adapters.
3. Find the device with the names Wireless, Wi-Fi, 802.11 or the model of your adapter (for example, Intel Wireless-AC 9560).
4. If there is a down arrow (🔽) next to the device name, right-click on it and select Engage.

If the adapter is not listed or is marked with an exclamation mark (⚠️), this indicates problem with the driverIn this case:

• 🔄 Right-click on the adapter → Update driver → Automatic search.
• 💾 If the automatic search does not help, download the driver from the website of the laptop or adapter manufacturer (for example, Intel, Qualcomm Atheros, Realtek).
• 🗑️ As a last resort, remove the device from the device manager (right click → Remove device), then restart your PC - Windows will try to install the driver again.

Open Device Manager (Win+X)

Find the "Network Adapters" section

Check the Wi-Fi module status (enabled/disabled)

Update or reinstall the driver if necessary-->

⚠️ Attention: If Wi-Fi disappears again after updating the driver, try rolling back to the previous version. To do this, select Properties → Driver → Roll Back DriverThis is relevant for adapters. Realtek, which often conflict with the latest versions of Windows 10.

3. Diagnosing network parameters via the command line

If the adapter is turned on, but the network is still not visible, the problem may be in network settingsYou can check them using the command line. Open it as administrator (Win + X → Command Prompt (Administrator)) and execute the commands sequentially:

netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns

These commands will reset the settings TCP/IP, Winsock (a library for network connections) and clear the DNS cache. After completing these steps Be sure to restart your computer.

If the problem persists after rebooting, check the status Windows services, responsible for the network. In the command line, enter:

sc query WlanSvc
sc query Dhcp

In your answer, pay attention to the line STATE. If it is indicated there STOPPED, the service is disabled. To start it:

net start WlanSvc
net start Dhcp

4. Checking Group Policy and Registry

In some cases, Wi-Fi may be disabled through group policy (relevant for corporate PCs) or changes to the registry. If you have recently installed system optimization programs (for example, CCleaner, Advanced SystemCare), they could accidentally change critical parameters.

To check the group policy:

1. Click Win + R, enter gpedit.msc and press Enter.
2. Follow the path: Computer Configuration → Administrative Templates → Network → Wireless Settings.
3. Make sure the parameter Deny access to wireless network settings installed in Not set or Disabled.

If gpedit.msc is not available (this happens in Home editions of Windows 10), check the registry:

1. Click Win + R, enter regedit.
2. Follow the path: HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\WlanSvc.
3. Make sure the parameter Start does it matter 3 (automatic start).

⚠️ Attention: Editing the registry may cause system instability. Before making changes create a restore point (Control Panel → Recovery → Configure System Restore). If errors appear after editing the registry, roll back the system.

5. Update Windows and reset network components

Microsoft regularly releases updates that fix bugs in network components. If your Windows 10 If the app hasn't been updated in a while, this could be the cause of the Wi-Fi issue. To check for and install updates:

1. Open Settings → Update & Security → Windows Update.
2. Click Checking for updates.
3. If there are optional updates (especially in the section Drivers), install them.

If the updates did not help, please do reset network components:

1. Go to Settings → Network & Internet → Status.
2. Scroll down and click Network reset.
3. Confirm the action and restart your computer.

This procedure will remove all network adapters and their settings, and then Windows will reinstall them. Attention: After the reset, you will have to re-enter your Wi-Fi network passwords.

sfc /scannow
dism /online /cleanup-image /restorehealth

6. Checking the router and alternative connection methods

If everything is configured correctly on your computer, but Wi-Fi still doesn't work, the problem may be on the device's side. routerHere's what you need to check:

• 🔄 Reboot your router (unplug it from the outlet for 30 seconds).
• 📶 Make sure that on the router Wi-Fi broadcast mode is enabled (sometimes it turns off after a crash).
• 🔒 Check if it has changed network password (for example, after resetting the router).
• 📡 Try connecting to a different network (for example, from your phone in hotspot mode).

If Wi-Fi doesn't work only on Windows 10, but on other devices everything is fine, try alternative connection methods:

• 🔌 Connect to the router via Ethernet cable and check if the internet is working.
• 📱 Use USB modem or phone in modem mode.
• 🖥️ If you have PCI-e adapter, try connecting external USB Wi-Fi module.

⚠️ Attention: On some routers (for example, TP-Link or ASUS) there is a function WPS, which can block new connections. If the indicator WPS blinking, press the button WPS on the router to reset the pairing mode.

7. Hardware faults: how to identify them

If none of the software methods helped, the problem may be in hardware failure Wi-Fi module. This applies to:

• Laptops after a fall or impact.
• A PC with a built-in Wi-Fi adapter that stopped working after a thunderstorm or power surge.
• Devices that lose Wi-Fi when they heat up (for example, after an hour of operation).

To check the hardware:

1. Test the adapter on another device. If this is USB Wi-Fi module, connect it to another PC. If it's a built-in adapter in your laptop, try booting Live Linux (For example, Ubuntu from a flash drive) and check if Wi-Fi works there.
2. Check if the adapter is detected in the BIOS. Restart your PC, go to BIOS (Del, F2 or Esc when booting) and check the section Advanced → Onboard Devices (Names may vary). If the Wi-Fi adapter is disabled or not visible, this indicates a malfunction.
3. Check the antennas. In laptops, the Wi-Fi antennas are connected to the module via thin cables. If these become loose or damaged, the signal will drop. Disassemble the laptop (or contact a service center) and ensure the cables are securely connected.

If the adapter does not work in any OS and is not detected in the BIOS, it will have to be replaceFor laptops, any compatible module will work (for example, Intel 7260 or Broadcom BCM94360), for PC - PCI-e or USB adapter (For example, TP-Link TL-WN823N).
