Arduino 2009 Wiznet Ethernet Shield proper reset
This is a reset button solution to fix network operation in arduino ethernet.
Problem: Arduino 2009 with wiznet w5100 ethernet shield does not start network operations after power-up.
It works well if the reset button is pressed.
Solution: I implemented davekw7x’s suggestions (THANK YOU!), as cited in this arduino forum page (ref. reply #11)
this solution requires a 10kOhm resistor, and a 10nf capacitor.
Here are the detailed steps and some pictures:
- bend outwards the ethernet shield reset pin “leg”, so that it will not go in the arduino reset socket.
- solder the 10kOhm resistor between reset pin and the nearby 3.3 Vcc
- solder the 10nf capacitor between reset pin and ground
