WiFi Shield V2.2 for Arduino (802.11 b/g/n)

FAQ

• Can this shield cover long distance up to 1500m.

  i have problems with WiFi Shield V3 RPSMA (802.11b/g/n) configuration.
  I'm using the official WiFi shield on top of Uno R3 and I'm trying the examples provided in the WiFi library, but unfortunately the serial says that the "WiFi shield not present"

  Would anyone please tell me how to solve such a problem? and is there anything missing in the code that I should add?

  Regards

  here's the code

  ============================================
  #include <spi.h>
  #include <wifi.h>

  char ssid[] = "wifiname"; // your network SSID (name)
  char pass[] = "wifipass"; // your network password
  int keyIndex = 0; // your network key Index number
  int status = WL_IDLE_STATUS; // the Wifi radio's status

  void setup() {
  //Initialize serial and wait for port to open:
  Serial.begin(9600);
  while (!Serial) {
  ; // wait for serial port to connect. Needed for Leonardo only
  }

  // check for the presence of the shield:
  if (WiFi.status() == WL_NO_SHIELD) {
  Serial.println("WiFi shield not present");
  // don't continue:
  while (true);
  }

  // attempt to connect to Wifi network:
  while ( status != WL_CONNECTED) {
  Serial.print("Attempting to connect to WEP network, SSID: ");
  Serial.println(ssid);
  status = WiFi.begin(ssid, keyIndex, pass);

  // wait 10 seconds for connection:
  delay(10000);
  }

  // once you are connected :
  Serial.print("You're connected to the network");
  }

  void loop() {
  // check the network status connection once every 10 seconds:
  delay(10000);
  Serial.println(WiFi.status());
  }
