I changed node arduino to mega and it worked first try. Thanks for help

@TheoL
W5100 is powered from 5V because it has own regulator. I changed to serial gateway and it's node still doesn't find parent.

I added :

#define MY_RF24_DATARATE RF24_1MBPS // see (https://forum.mysensors.org/topic/4631/nrf24l01-can-t-find-parent-on-gateway/7)

but it didn't help.
My node code:

#include <Arduino.h>

 * The MySensors Arduino library handles the wireless radio link and protocol
 * between your home built sensors/actuators and HA controller of choice.
 * The sensors forms a self healing radio network with optional repeaters. Each
 * repeater and gateway builds a routing tables in EEPROM which keeps track of the
 * network topology allowing messages to be routed to nodes.

 * REVISION HISTORY
 * Version 1.0 - February 15, 2014 - Bruce Lacey
 * Version 1.1 - August 13, 2014 - Converted to 1.4 (hek)
 *
 * DESCRIPTION
 * This sketch provides a Dimmable LED Light using PWM and based Henrik Ekblad
 * <henrik.ekblad@gmail.com> Vera Arduino Sensor project.
 * Developed by Bruce Lacey, inspired by Hek's MySensor's example sketches.
 *
 * The circuit uses a MOSFET for Pulse-Wave-Modulation to dim the attached LED or LED strip.
 * The MOSFET Gate pin is connected to Arduino pin 3 (LED_PIN), the MOSFET Drain pin is connected
 * to the LED negative terminal and the MOSFET Source pin is connected to ground.
 *
 * This sketch is extensible to support more than one MOSFET/PWM dimmer per circuit.

@electrik it's led dimmer code with node id 10 added

@TheoL about 50cm but i tried putting node few meters away

I have ethernet gateway based on arduino mega and w5100. I'm trying to connect node to the gateway but i have no success. My gateway recieves find parrent from node and sends message back but node doesn't recieve it. I tried lots of things. I have 220uf capasitors on both radios. Node uses arduino uno.
