Hi there,
I just have weird witness about W5100. When I do something physical such measure NO or NC on relay.
Or plug in my RS232-usb converter.

The W5100's  LINK, SPD, RX, TX led will gery all(they are blinking or just on before), and then they will turn into normal(blinking or just on) after about 1 second.
It seems this problem does not affect W5100 because the program still works fine after such a situation.
So I am thinking if I have some EMI problem...
Actually I am not sure, can you help me?
