This example shows how to set the static IP address, 192.168.0.177, of the LAN network to the WiFi shield:

#include <SPI.h>
#include <WiFi.h>

// the IP address for the shield:
IPAddress ip(192, 168, 0, 177);    

char ssid[] = "yourNetwork";    // your network SSID (name)
char pass[] = "secretPassword"; // your network password (use for WPA, or use as key for WEP)

int status = WL_IDLE_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");
    while(true);  // don't continue
  }

  WiFi.config(ip);

  // attempt to connect to Wifi network:
  while ( status != WL_CONNECTED) {
    Serial.print("Attempting to connect to SSID: ");
    Serial.println(ssid);
    // Connect to WPA/WPA2 network. Change this line if using open or WEP network:    
    status = WiFi.begin(ssid, pass);

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

  // print your WiFi shield's IP address:
  Serial.print("IP Address: ");
  Serial.println(WiFi.localIP());
}
