Real SSID detection — Displays the actual connected WiFi network SSID instead of the Windows profile name.

Real adapter detection — Shows the actual Ethernet adapter name and connection name instead of generic labels.

Memory leak fixes — Proper cleanup of native WLAN API handles. Fixed BackgroundWorker disposal issue.

Optimized P/Invoke — Reduced redundant native API calls for better performance.

C#

lanConnection1.ColorEnabled = Color.Green;
lanConnection1.ColorDisabled = Color.WhiteSmoke;
lanConnection1.ColorDisconnect = Color.Red;
lanConnection1.EnableClickInfo = true;
lanConnection1.Scan = true;              // Start monitoring
