That was indeed the solution. Sometimes it can be so simple. Did not think that wiring the radio would matter. Thanks!

@mfalkvidd thanks for your reaction; i am using an app to find devices in my network and it did not show the gateway, thus i jumped to the conclusion the gw did not get an ip adress. I shall try it tomorrow with the radio attached.

Hi, I am pretty new to this. I have a working serial gateway, but for convenience I want an ethernet Gateway. For that I am using an Arduino Uno and a W5100 ethernetshield. I am using the W5100 gateway sketch with the only modification that i commented the line with an ip adress so it uses dhcp and uncommented the line for the dhcp renewal.

But somehow i dont get an ip adress when i connect it to the netwerk. If i connect the cable to my laptop it works and my laptop gets an ip adress so the cable is good. I do not have an other arduino project currently on my netwerk, so the mac adress is unique in my network.

When i look at the debug it says:

0;255;3;0;9;MCO:BGN:INIT GW,CP=RNNGA--,VER=2.1.1
0;255;3;0;9;TSM:INIT
0;255;3;0;9;TSF:WUR:MS=0
0;255;3;0;9;!TSM:INIT:TSP FAIL
0;255;3;0;9;TSM:FAIL:CNT=1
0;255;3;0;9;TSM:FAIL:PDT
0;255;3;0;9;TSM:FAIL:RE-INIT

With the CNT going up to 7. But with all the rest the same.

I do not have the rf24 yet connected as i first wanted to test this first.

What am I missing?
