☑️ Driver Diagnostic Checklist
Windows Services and Network Settings
A special service in the operating system is responsible for detecting and connecting to wireless networks. If the service WlanSvc (Offline WLAN Setting) is stopped or disabled, the Wi-Fi icon will disappear from the taskbar and the settings will be unavailable.
You can check the service status through the Run menu (keys Win + R). Enter the command services.msc and press Enter. Find "WLAN AutoConfig Service" in the list. Make sure the startup type is set to "Automatic" and the service is running.
Sometimes resetting network settings to factory defaults can help. This can be done via the command prompt with administrator rights. Run the following commands one by one:
netsh winsock resetnetsh int ip reset
ipconfig /release
ipconfig /renew
ipconfig /flushdns
After running these commands, you must restart your computer. This procedure clears the DNS cache and resets TCP/IP stacks, which often resolves connection issues when the hardware is working properly.
Windows 10 and 11 also introduced a "Network Reset" feature in System Settings. It removes all network adapters and reinstalls them, returning their settings to their original values. It's a drastic but effective method.
