If Windows 10 shows no Wi-Fi networks, the issue usually stems from a disabled wireless adapter, outdated drivers, or incorrect network settings. Start by verifying the physical Wi-Fi switch and checking Device Manager for driver errors. Reinstalling the network adapter driver often resolves the "no networks found" error immediately.
Verify Physical Switches and Airplane Mode
Before diving into software configurations, you must ensure that the hardware is not blocking the signal. Many laptops have a physical switch or a function key combination that disables all wireless radios. Look for an icon resembling a radio tower or an antenna on your keyboard'sF1 through F12 keys. Pressing Fn plus the corresponding key toggles the wireless state. If your device has a physical slider on the side or front edge, ensure it is set to the enabled position.
Additionally, check the Action Center in the bottom-right corner of the taskbar. The Airplane mode tile must be grayed out (off). If it is blue, click it to disable airplane mode. This setting cuts power to all wireless adapters, including Bluetooth and Wi-Fi. After disabling it, wait ten seconds for the system to re-enumerate available networks. If the list remains empty, proceed to the next diagnostic step.
Check Network Adapter Status in Device Manager
The most common cause for missing networks is a disabled or malfunctioning network adapter. Open the Start menu, typeDevice Manager, and press Enter. Expand the section labeled Network adapters. Look for an entry containing words like Wireless, Wi-Fi, Atheros, Intel, or Realtek. If you see a yellow exclamation mark next to the adapter, the driver is corrupted. Right-click the adapter and select Update driver, then choose Search automatically for updated driver software.
If the adapter is disabled, indicated by a down arrow icon, right-click it and select Enable device. In some cases, the adapter may not appear at all. Click the Action menu at the top and select Scan for hardware changes. If the wireless adapter still does not appear, the hardware may be failing, or the BIOS/UEFI settings might have disabled it. You can also try uninstalling the device from Device Manager and restarting the computer. Windows will attempt to reinstall the default driver upon reboot, which often fixes configuration glitches.
Restart the WLAN Service
Windows relies on the Wireless LAN AutoConfig service to manage connections. If this service stops running, your system cannot detect any networks. PressWin + R, type services.msc, and hit Enter. Scroll down to find WLAN AutoConfig. Check the status column; it should say Running. If it is stopped, right-click the service and select Start.
You should also verify the Startup type. Double-click the service and ensure the Startup type is set to Automatic. If it was set to Manual or Disabled, change it to Automatic and click Apply. Restart your computer to ensure the service starts correctly with the operating system. This step is crucial because even if the driver is installed, a stopped service prevents the UI from displaying available networks.
Reset Network Stack Settings
Corrupted TCP/IP stacks or DNS caches can prevent the system from querying access points properly. Open Command Prompt as an administrator by right-clicking the Start button and selecting Terminal (Admin) or Command Prompt (Admin). Run the following commands one by one, pressing Enter after each:netsh winsock reset
netsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdnsReinstall Network Drivers Manually
If automatic updates fail, manual installation is necessary. Visit the manufacturer’s website for your laptop or motherboard model. Download the latest wireless LAN driver compatible with Windows 10. In Device Manager, right-click the wireless adapter and select Uninstall device. Check the box that says Delete the driver software for this device if available. Unplug the Ethernet cable if connected, then restart the PC. Once the system boots, install the downloaded driver package. Follow the on-screen instructions to complete the installation. After restarting again, check if Wi-Fi networks appear. This method bypasses generic Microsoft drivers that may lack specific features for your hardware.

What if my Wi-Fi adapter is missing from Device Manager?
This usually indicates a hardware failure or a BIOS-level disablement. Check your BIOS settings to ensure the wireless card is enabled. If it remains invisible, the internal antenna or card may be physically disconnected or broken.
Can a virus cause Windows to stop finding Wi-Fi networks?
Malware can modify registry keys or disable services to block connectivity. Run a full system scan using Windows Defender or a trusted third-party antivirus tool to remove any threats that might be interfering with network functions.
Why does Wi-Fi work on other devices but not my PC?
This isolates the problem to your computer rather than the router. Focus on troubleshooting the local adapter, drivers, and Windows network stack settings. Ensure your PC is not set to connect only to hidden SSIDs if your router broadcasts them.
How do I check if my Wi-Fi adapter is overheating?
Laptop wireless cards rarely overheat under normal use. However, excessive heat can throttle performance. Ensure your laptop vents are clear of dust and that the cooling fan is operational. Use monitoring software to check CPU and GPU temperatures, as general system heat can affect nearby components.
Is resetting the router necessary for this issue?
No, since other devices can likely connect, the router is functioning correctly. Resetting the router will not fix a client-side detection issue. Only reset the router if you suspect IP conflicts or authentication errors affecting multiple devices simultaneously.
