Fix Unknown Strange Devices Showing Network Windows 11

If you’re facing strange or unidentified devices appearing on your Windows 11 network, the culprit might be Windows Connect Now (WCN). WCN lists all past devices connected to your network, not just current ones. To resolve this:

  • Disable WCN:
    • Go to Settings > Network & internet > Wi-Fi.
    • Click on Manage known networks.
    • Select each unknown device and click Forget.

Another cause of unknown devices could be a lack of strong network protection. If your Wi-Fi uses the WPA protocol, it’s not fully secure. To fix it:

  • Disable WPS:
    • Log into your router’s settings.
    • Navigate to the Wireless section.
    • Find the WPS option and disable it.

Key Takeaways:

  • Windows Connect Now can show past connected devices, making them appear as unknown.
  • The WPA protocol doesn’t provide complete network security, allowing unknown devices to connect.
  • Disabling WCN and WPS can resolve the issue of strange devices on your Windows 11 network.
