Hello everyone, I use mini ethernet module with w5500 with arduino nano. The problem is when I supply my board with dc current sometimes system works great but sometimes(unplug dc voltage and then plug it again ) I have connection problem. Leds on the ethernet socket like :
When I have connection problem : Firstly green led is on for 0.5 second or so and then green led is off, at the moment that green is off, yellow led is on for 0.5 second or so and then yellow led is off. Led status goes on like this repeatedly.
what might be the problem with ?
