I have problems with the Wi-Fi shield example code.
#include <SPI.h>
#include <WiFi.h>
char ssid[] = "*****"; // your network SSID (name)
char pass[] = "*****"; // your network password
int status = WL_IDLE_STATUS;
char servername[]="google.com"; // remote server we will connect to
WiFiClient client;
void setup() {
Serial.begin(9600);
//disable SD SPI
pinMode(4, OUTPUT);
digitalWrite(4, HIGH);
Serial.println("Attempting to connect to WPA network...");
Serial.print("SSID: ");
Serial.println(ssid);
status = WiFi.begin(ssid, pass);
if ( status != WL_CONNECTED) {
Serial.println("Couldn't get a wifi connection");
// don't do anything else:
while(true);
}
else {
Serial.println("Connected to wifi");
Serial.println("\nStarting connection...");
// if you get a connection, report back via serial:
if (client.connect(servername, 80)) {
Serial.println("connected");
// Make a HTTP request:
client.println("GET /search?q=arduino HTTP/1.0");
client.println();
}
}
}
void loop() {
}
The Wi-Fi Shield has connected with the internet Wi-Fi, but the last printing was "Starting connection..." I can't get to connect to (google.com), why?

Have you upgraded the firmware in your wifi shield? If not, it will have problems connecting. Compile and upload this sketch. If it shows the firmware version as 1.0.0, then you need to upgrade the firmware. If it shows 1.1.0, then it is current as of today.
#include <SPI.h>
#include <WiFi.h>
void setup() {
//Initialize serial and wait for port to open:
Serial.begin(9600);
// check for the presence of the shield:
if (WiFi.status() == WL_NO_SHIELD) {
Serial.println("WiFi shield not present");
// don't continue:
while(true);
}
Serial.print("Firmware version: ");
Serial.println(WiFi.firmwareVersion());
}
void loop() {}
Please Note: The chips are numbered differently but run the same Wi-Fi firmware. You can upgrade the firmware without any worries.

I had this problem aswell. The problem was a bug with the official editor of arduino. I fixed this by downgrading the editor to version 1.0.3. (from 1.0.5) You can find a download link for it at the Arduino website.
Hope this helped!

2Please add information about your code: what does it do? how does it work?sachleen– sachleen2014年07月16日 16:06:36 +00:00Commented Jul 16, 2014 at 16:06
Serial.println(status);and whichWL_status is returned? Did it actually connect (WL_CONNECTED) or is it some other result?
