Variable delay in ping

Question

Hi, I have a custom design using W5500. When I ping it using my PC, generally the ping takes <1ms, but every once in a while it takes more time (~5ms to 15ms) although I am not doing anything else on the W5500 at the moment. It is not a problem for me as such, just wanted to understand the reason if anyone can explain. Thanks

Hi @Mohit_Singh , Have you connected w5500 LAN directly to PC…?? If you have connected W5500 to any server or router and it pings late, may be connection issue or speed issue in router Thanks and Regards Teju S H

Hi again, Can anyone suggest me something on this? I checked with a commercial W5500 module pcb and did not find this variable delay in ping times in that. It is happening only in my custom PCB. There is no switch in between. I am directly pinging the board.
