Hi, recently picked up an ethernet shield for my Arduino Uno R3. However… anytime I plug in an ethernet cable, the
unit immediately goes into reset (red light comes on.) The device does not show up as a wired device in my router
administration menu… however does light up the connection light on the router.
I’ve tried using an external power supply, which didn’t work. Fearing a bad board, I tried swapping it out for a new one,
same result. The arduino has been loaded with several different sketches from the ethernet examples section in the
arduino IDE, but none of them produce any results. Serial monitor reports the device’s IP to be 0.0.0.0.
Has anyone else ran into this?
