hi

we are newly using w5500 with out project with stm32f407 , works well , we brought w5500 ready made board from china , when some 230 volt ac contactor get on/off , w5500 stops working , and we need to reset the w5500 again and again , but stm32 will be working with out any issue ,we are planning to implement this w5500 with our pcb as plugin type ,can u suggest any industrial type w5500,if it works well in industrial we may need more numbers of ic.

regards

ravi
