wifi shield not present

Hi there,

As you wil notice I'm not very experienced in Arduino yet, I can't get my Arduino wifi shield to work. I plugged it on to my arduino board. What I do next is try this standard example code (below). All I get is a "wifi shield not present" message. Hope someone can help me with this...

Thanks in advance

/*
 
 This example connects to an unencrypted Wifi network. 
 Then it prints the  MAC address of the Wifi shield,
 the IP address obtained, and other network details.

Hi,

All I get is a "wifi shield not present"

which Arduino board are you using?
UNO / 2009 / Leonardo / other?

Same thing happens to me when i use wifi shield with the 2009 board..

Sorry for the late reply, but I have an Arduino UNO.

i am using mega and even i am getting the same message.
Can someone please tell us whats the problem with wiring?

& which wifi shield?

I am using shield provided by

http://www.protocentral.com/103-wifi-shield.html

But i think te wiring that i made was wrong. can you please tell me how should i do that?

The WiFi library and the code in the initial post works with the OFFICIAL WiFi shield, and ONLY the official WiFi shield.

The fact that you are NOT using the official WiFi shield means that you can NOT use the WiFi library.

Okay but I am using the orginal wifi shield and de Arduino UNO and i get this message what is going wrong?
