Hello
I am facing unknown behavior from connecting enc28j60 to router.
When using ethercard library back soon example
. // Present a "Will be back soon web page", as stand-in webserver.

#include <EtherCard.h>
#define STATIC 1 // set to 1 to disable DHCP (adjust myip/gwip values below)
#if STATIC
// ethernet interface ip address
static byte myip[] = { 192,168,8,200 };
// gateway ip address
static byte gwip[] = { 192,168,8,1 };
#endif
// ethernet mac address - must be unique on your network
static byte mymac[] = { 0x74,0x69,0x69,0x2D,0x30,0x31 };
byte Ethernet::buffer[500]; // tcp/ip send and receive buffer
const char page[] PROGMEM =
"HTTP/1.0 503 Service Unavailable\r\n"
"Content-Type: text/html\r\n"
"Retry-After: 600\r\n"
"\r\n"
"<html>"
"<head><title>"
"Hello world "
"</title></head>"
"<body>"
"<h3>hello world</h3>"
"</body>"
"</html>"
;
void setup(){
Serial.begin(57600);
Serial.println("\n[backSoon]");
// Change 'SS' to your Slave Select pin, if you arn't using the default pin
if (ether.begin(sizeof Ethernet::buffer, mymac, SS) == 0)
Serial.println( "Failed to access Ethernet controller");
#if STATIC
ether.staticSetup(myip, gwip);
#else
if (!ether.dhcpSetup())
Serial.println("DHCP failed");
#endif
ether.printIp("IP: ", ether.myip);
ether.printIp("GW: ", ether.gwip);
ether.printIp("DNS: ", ether.dnsip);
}
void loop(){
// wait for an incoming TCP packet, but ignore its contents
if (ether.packetLoop(ether.packetReceive())) {
memcpy_P(ether.tcpOffset(), page, sizeof page);
ether.httpServerReply(sizeof page - 1);
}
}
I found the IP listed in arp router list but I didn't find any TCP package in wire shark and the server could not reach by chrome I try to change Mac address and ip but didn't solve it
