W5500 not Pinging With DLINK DES-1008A

I am using W5500 Module with STM32 for Ethernet Application. Whenever I am connecting the module with my Laptop Ethernet Port and Ping it starts ping instantly. All the socket applications are also working. I have multiple such modules, all are working fine individually. Now, when I am connecting three such modules with network switch DES-1008A of D-Link only one of the module is pinging. The settings are as follows: Module 1 : IP : 192.168.100.26 GW:192.168.100.1 SB:255.255.255.0 MAC: 00-08-dc-05-00-05 Module 2 : IP : 192.168.100.27 GW:192.168.100.1 SB:255.255.255.0 MAC: 00-08-dc-05-00-0C Module 3 : IP : 192.168.100.28 GW:192.168.100.1 SB:255.255.255.0 MAC: 00-08-dc-05-00-0B Only 192.168.100.28 is Pinging. I have searched the internet about the problem. The Termination resistors are 49R9 and the modules are in auto Negotiation mode. Soumya
