I have an arduino yun that has two times the same MAC address:
eth1 Link encap:Ethernet HWaddr 90:A2:DA:F8:15:2E wlan0 Link encap:Ethernet HWaddr 90:A2:DA:F8:15:2E
That seems to make it difficult in a DHCP network (I'm not able to connect wirelessly, I only get an IP for the eth1-Interface). Is there a way to change the MAC address of one of the device.
Best regards, Dani
