SOLVED!!!!! it make me crazy but finally i found on forum
@dallienl said in Building an Ethernet Gateway:

Had lots of issues getting this to work. The issue seems to be with the ethernet part, as I only have an ethernet board attached I removed the lines for the radio and the pin redirection. Still the code kept restarting all the time or just not being able to connect the controller.

AVR version of the Arduino 1.8.0 kit needs to be downgraded. I had 1.6.16 and downgraded to 1.6.11.

Open Arduino. Tools > Board: xxxxx > Boards manager... > Click "Arduino AVR Boards" > Select Version > 1.6.11

Recompile and you are good.

so i had to downgraded AVR version of the Arduino 1.8.0 kit and thats it i knew its smothing in arduino IDE

ok my gw now work sorry i forget to connect radio vcc but everything else not working every sensor i try triple check wiring bothing

look like everything that i programmed not working about half years ago when i start with my sensors everything that i try work bu when i have time to play with mysensors again nothing worked make me crazy i have full box of sensors and boards but nothing cant get to work only sensbender gw and sensbender micro that i didn't touch i think that must be something with arduino ide

now even sensbender micro that it work on sensbender gw don't work on my gw it work only if i connect sensbender gw

i try new serial gw on nano but same problem i delete all nodes and when i turn on some sensors my controller find it only one node without name. My only working sensor (one of the woking sensebender out the box) display 2 nodes one without name and node with sensebender micro name what for is that first node ID 0
screen shot how it display every sensor:

i just try this and its same
is it possible that is anythig with gw i'm using official sensebender gw

reinstal arduino, libary, clear eprom nothing gonna lose my mind i think i'm gonna throw everything in trash
