seeedstudio ethernet problem

Hi All,

I have a couple of seeedstudio ethernet v1.0, and recently I can’t get it work correctly due to an error trying to get hardware information. I put this code (from arduino forums) and always get the same EthernetNoHardware error.

#include <SPI.h>
#include <Ethernet.h>

byte mac[] = {0xDE, 0xAD, 0xBE, 0xEF, 0xFE, 0xAA};
IPAddress ip(10, 0, 0, 177);

void setup() {
// Open serial communications and wait for port to open:
while (!Serial) {
; // wait for serial port to connect. Needed for native USB port only

Ethernet.begin(mac, ip);

if (Ethernet.hardwareStatus() == EthernetNoHardware) {
Serial.println(“Ethernet shield was not found.”);
else if (Ethernet.hardwareStatus() == EthernetW5100) {
Serial.println(“W5100 Ethernet controller detected.”);
else if (Ethernet.hardwareStatus() == EthernetW5200) {
Serial.println(“W5200 Ethernet controller detected.”);
else if (Ethernet.hardwareStatus() == EthernetW5500) {
Serial.println(“W5500 Ethernet controller detected.”);

void loop () {}[/code]

Thanks in advance
