I am having problems with the Arduino crashing when after receiving a few inputs. It only happens with the motors attached and I am wondering if it is due to incompatibility between the shields. Using adafruit shields

"The following pins are in use only if the DC/Stepper noted is in use:
Digital pin 11: DC Motor #1 / Stepper #1 (activation/speed control)
Digital pin 3: DC Motor #2 / Stepper #1 (activation/speed control)
Digital pin 5: DC Motor #3 / Stepper #2 (activation/speed control)
Digital pin 6: DC Motor #4 / Stepper #2 (activation/speed control)"

"Arduino uses digital pins 10, 11, 12, and 13 (SPI) to communicate with the W5100 on the ethernet shield. These pins cannot be used for general i/o."

Since they both use pin 11 this would cause a problem right? What would be the best solution?

Thank you for thoughts/inputs.

It seems that both pin 11 and 12 are used by both shields and they cannot be stacked.  =(

Does anybody have a suggestion to how to control 4 DC motors over ethernet/wifi?

thanks
