Hi,
I have the same problem and tested all the codes you mentioned above. Besides, I connected my shield to PC and read the MAC add because I thought maybe wrong MAc add will give the DHCP config error. I have no SD card and these LEDs are on:
LINK
100M
FULLD
I always get theis error:
Failed to configure Ethernet using DHCP
What should I do?
The code I test:
#include <SPI.h>
#include <Ethernet.h>
// Enter a MAC address for your controller below.
// Newer Ethernet shields have a MAC address printed on a sticker on the shield
byte mac[] = {
0x00, 0x06, 0x4F, 0x0D, 0xAC, 0xA9 };
// Initialize the Ethernet client library
// with the IP address and port of the server
// that you want to connect to (port 80 is default for HTTP):
EthernetClient client;
void setup() {
// start the serial library:
Serial.begin(9600);
// start the Ethernet connection:
if (Ethernet.begin(mac) == 0) {
Serial.println("Failed to configure Ethernet using DHCP");
// no point in carrying on, so do nothing forevermore:
for(;;)
;
}
// print your local IP address:
Serial.println(Ethernet.localIP());
}
void loop() {
}
