wrong mac address received from arduino

Using Arduino Interfacing w/ Software on the Computer
#1

Hi all,
I am trying to get my Arduino’s mac address so that i could give it a static IP.
I used a very simple code taken from the arduino website (can be found at the end of the post)
I seem to be getting a mac address like this:

X1:Y2:Z:Z4:U5:O3

these arn’t the real letters, but the point is that the 3rd byte keeps giving my just a one letter and nothing else, and this is not a valid mac address.
i tried to play around and only display that byte and other such games, but they all were not successful.
Anyone have any idea on how I can manage to get the full mac address?
Thanks!

Code used (of course i change the ssid and added pass etc):

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

char ssid = “yourNetwork”; // the name of your network
int status = WL_IDLE_STATUS; // the Wifi radio’s status

byte mac[6]; // the MAC address of your Wifi shield

void setup()
{
Serial.begin(9600);

status = WiFi.begin(ssid);

if ( status != WL_CONNECTED) {
Serial.println(“Couldn’t get a wifi connection”);
while(true);
}
// if you are connected, print your MAC address:
else {
WiFi.macAddress(mac);
Serial.print(“MAC: “);
Serial.print(mac[5],HEX);
Serial.print(”:”);
Serial.print(mac[4],HEX);
Serial.print(":");
Serial.print(mac[3],HEX);
Serial.print(":");
Serial.print(mac[2],HEX);
Serial.print(":");
Serial.print(mac[1],HEX);
Serial.print(":");
Serial.println(mac[0],HEX);
}
}

void loop () {}

X1:Y2:Z:Z4:U5:O3

these arn't the real letters, but the point is that the 3rd byte keeps giving my just a one letter and nothing else, and this is not a valid mac address.

Actually, it is, just missing a zero. How does this look?
X1:Y2:0Z:Z4:U5:O3
Maybe you need to use sprintf() to format your mac address. Something like this:

sprintf(myBuffer,"%02X:%02X:%02X:%02X:%02X:%02X",mac[0],mac[1],mac[2],mac[3],mac[4],mac[5]);
Serial.println(myBuffer);

That way it will include any leading zeros.

edit: My bad. It should have been %02X, not %02u.

all it was, was a missing 0.
Thanks a lot!!!
