Hello sir, i have emotive epoc x and bci osc license. I am using arduino uno and ethernet shield w5100 to stream data. code is uploading successfully but getting this "Failed to configure Ethernet using DHCP" in Arduino serial monitor.

I use ethernet cable to connect w5100 directly with my computer. Do i have to use any switch or router to connect ethernet shield ? or can we connect ethernet shield w5100 directly with computer with the ethernet cable?

i have used following code, kindly help .
