Hello everybody,
i'm having an issue with arduino ethernet shield W5100 v3 freezing.
Long / short story:
I'm building a complete home automation system, sensors, web interface, data logging, light control. (RBG strips) etc.
For a long period a was having an issue with ethernet shield freezing periodically. I saw so many threads on this that i stop investigating because i I thought is a bug in the library.
Last week i wanted to take this to the next step and control 220V appliances, this is where the issue became more obvious.
When relay clicks on or off the ethernet shield is freezing. Arduino due is still running.
First instinct was to blame the relay shield, but when i plug in a 50 W lamp or any other device directly, the shield is still freezing.
Tried to mount ferrite bead on the cables but no luck.
The issue appears if i plug it in another room also, but not so quick...
What can be the issue.
Thanks in advance.
