W5500 does not ping

Question

Hello! I am using Wiz550io V1.3 together with STM32F401 DISCOVERY. I use CubeMX32 and IAR EW for ARM. I want to ping the module, but I don’t get a response from it.

wiz_NetInfo gWIZNETINFO = { .mac = {0x00, 0x08, 0xdc, 0x5f, 0x39, 0x4a}, .ip = {192, 168, 22, 3}, .sn = {255, 255, 255, 0}, .gw = {192, 168, 88, 1}, .dns = {0, 0, 0, 0}, .dhcp = NETINFO_STATIC }; Hello @Orangeenush ! I can see that your ip and gw network range are not matching… Please set same network range in this file and also please have same network zone in your destination network settings.
