ENC28j60 Ping issuse

For my project I m using the ENC28J60 ethernet module and the library is Arduino UIPEthernet Library The issue I m facing with this is, the IP pings when ethernet connected to my PC but when I connecting it with Switch it is not pinging properly. Can you help with me to solve this issue as it is an urgent one.

my code 

#include <SPI.h>
#include <UIPEthernet.h>
#include <SoftwareWire.h>
SoftwareWire myWire( 10, 11);
EthernetServer server = EthernetServer(1000);
uint8_t MACADDR[15];
void setup()
{
  Serial2.begin(9600);

  uint8_t mac[6];
    myWire.beginTransmission(0x53); // transmit to device #44 (0x2c)   // device address is specified in datasheet
  myWire.write(byte(0xFA));            // sends instruction byte
  myWire.endTransmission();     // stop transmitting
  int n = myWire.requestFrom(80, 6);
  myWire.readBytes(mac, n);
  //  Serial2.println("--------------------");
  for (int i = 0; i < 6; i++)
  {
    Serial2.print(mac[i], HEX); //Communication card mac
  }
  sprintf(MACADDR, "%02X%02X%02X%02X%02X%02X", mac[0], mac[1], mac[2], mac[3], mac[4], mac[5]);
  //  Serial2.println(MACADDR);
//  Ethernet.begin(mac, myIP);
  IPAddress myIP(192,168,1,xx);

  Ethernet.begin(mac,myIP);
  Serial2.print("localIP: ");
  Serial2.println(Ethernet.localIP());
  Serial2.print("subnetMask: ");
  Serial2.println(Ethernet.subnetMask());
  Serial2.print("gatewayIP: ");
  Serial2.println(Ethernet.gatewayIP());
  Serial2.print("dnsServerIP: ");
  Serial2.println(Ethernet.dnsServerIP());

  server.begin();
}

void loop()
{
  size_t size;

  if (EthernetClient client = server.available())
    {
      while((size = client.available()) > 0)
        {
          uint8_t* msg = (uint8_t*)malloc(size);
          size = client.read(msg,size);
          Serial2.write(msg,size);
          free(msg);
        }
      client.println("DATA from Server!");
      client.stop();
    }
}

Thanks in Advance
