I can get a connection with WiFi, but eth0 does not work. I can see it via ssh:
2: eth0: <BROADCAST,MULTICAST8000> mtu 1500 qdisc noop qlen 1000
link/ether <redacted> brd ff:ff:ff:ff:ff:ff
but setting it up throws an error (doing this from the CoreELEC UI addon just does nothing and the button snaps back to “off”):
ip link set eth0 up
ip: ioctl 0x8914 failed: Device or resource busy
That doesn’t sound right.
What am I missing?
