Hello
I'm using enc28j60 ethernet controller and PIC18F2620 as a webserver to control some relay in a power system.
I notice that some time when there is any noise or spark like when contactor latch in a distance of 30cm can cause to make the enc28j60 to hungs or replay to ping with a high delay even when the noise is stopped the cotroller keeps hungs or have a high ping delay.
I used a cap on vcc and 5vspd on thernet pins but not fix the problem .
So any advice to solve the problem.
Best regards
