Conectar Arduino a Internet o LAN con Shield Ethernet W5100
The shield also includes a reset controller, to ensure that the W5100 Ethernet module is properly reset on power-up. Previous revisions of the shield were not compatible with the Mega and need to be manually reset after power-up.
Ethernet Shield W5100 R3 Support PoE For Arduino UNO Mega
Arduino Ethernet Shield R3. The Arduino Ethernet Shield allows an Arduino board to connect to the internet. It is based on the Wiznet W5100 ethernet chip providing a network (IP) stack capable of both TCP and UDP. The Arduino Ethernet Shield supports up to four simultaneous socket connections.
Arduino Ethernet Rev3 without PoE
The Arduino Ethernet Shield R3 (assembled) allows an Arduino board to connect to the internet. It is based on the Wiznet W5100 ethernet chip (datasheet). The Wiznet W5100 provides a network (IP) stack capable of both TCP and UDP.

Den W5100 gibt es als Shield beispielsweise fr den Arduino Uno oder als Board. Das Ethernet-Board ist relativ klein und kann somit gut verbaut werden. Leider scheinen alle am Markt befindlichen Boards auf dem gleichen Schaltplan zu basieren.

Ethernet shield w5100 reset only - Arduino Forum
Turn off Arduino Ethernet shield. is an old post, but maybe someone has the same problem. . . On the Arduino UNO board You actually have 2 pins connecting reset lines with Ethernet shield - one pin next to 3,3v, and one on the ICSP - pin 5. Note the W5100 is 3V and its reset is not directly tied to the Arduino, but rather to a Voltage

I'm trying to use a W5100 Arduino Ethernet Shield on a ATMega2560 using avr code. He mentions that the four callback functions should be modified, namely my_select(), my_deselect(), my_xchg() and my_reset() The w5100_webserv. c also contains the following definitions for SPI_PORT/DDR CS_PORT/DDR/BIT and RESET_PORT/DDR/SPI:

/18/2016Identified an issue with various W5100 (Wiznet) clone Ethernet shields - the issue is that upon applying power to the Arduino, the Ethernet shield doesn't initialise unless you press the reset button.
