//SSID of your network 
char ssid[] = "yourNetwork";

  // scan for existing networks:
  Serial.println("Scanning available networks...");

  // attempt to connect using WEP encryption:
  Serial.println("Attempting to connect to open network...");
  status = WiFi.begin(ssid);

  Serial.print("SSID: ");
  Serial.println(ssid);

}

void loop () {}

  // print the list of networks seen:
  Serial.print("SSID List:");

  // print the network number and name for each network found:
  for (int thisNet = 0; thisNet<numSsid; thisNet++) {
