LPC1768 mbed application board connecting to ethernet issue

I am having an issue connecting to ethernet with the LPC1768 mbed application board. I have tried countless EthernetInterface and EthernetNetIf cookbook examples. As well as… checking my ethernet port cable. The RJ45 data and power LED’s NEVER light up and I never get an IP Address print when calling eth.getIPAddress().

My ethernet cable is NOT the problem, because it connects just fine to a raspberry Pi. Im starting to think it’s a manufacturing fault on the mbed application board!!

If anyone had the same issue and found a solution, please let me know.
