Thanks for the tip. I've checked in /etc/udev files and directories, and there is no rule for naming interfaces. Instead of removing "net.ifnames=0" from the kernel command line, I have altered it to "net.ifnames=1". Gonna try removing it at once. But, imho, Odroid is a good hardware, and I have learned a lot about Linux - not Android - in their Odroid magazine. And their Ubuntu image works very good. And, as always, there are a lot of guys in the community. Thank you! Francisco
