detecting wi fi

Here is a nice option on CodePlex:
Managed Wifi API[^]

and here is the Google search[^] :)

Use the Managed Wifi API like this:

static void Main(string[] args) 
{     
  WlanClient client = new WlanClient();     
  foreach ( WlanClient.WlanInterface wlanIface in
                 client.Interfaces )
    {
      Wlan.WlanAvailableNetwork[] networks = 
            wlanIface.GetAvailableNetworkList( 0 );
      foreach ( Wlan.WlanAvailableNetwork network in networks )
      {
        Console.WriteLine( 
           "Found network with SSID {0} and Siqnal Quality {1}.", 
             GetStringForSSID(network.dot11Ssid), 
             network.wlanSignalQuality);
      }
   }
}

static string GetStringForSSID(Wlan.Dot11Ssid ssid)
{
  return Encoding.ASCII.GetString(ssid.SSID, 0, (int) ssid.SSIDLength); 
} 

The above code, by Taylor Leese, was copied from here[^].
