BCI-OSC { failed to configure Ethernet using dhcp}

[MohaFathi]

Hi , I have the BCI-OSC license and i want to send mental commands to control the motors of a robotic car , the problem is I can’t make a successful connection between the software and arduino ( I’m using Ethernet shield to connect the arduino uno to the Router and to the laptop by wifi because my router have only 1 port ) The problem is when I upload my code it gives me “ Failed to configure Ethernet using DHCP“ in the serial monitor .. So could you help me to know where the problem is ??

here is my code :

Hi @MohaFathi . i see there is a suggestion in: https://github.com/Emotiv/opensoundcontrol/issues/9 Did you try it?
