Description:

ifconfig only shows lo, wlan0 interfaces on the rpi. Below is a printout from a diagnostic script I created. I’m pretty stumped on what to do from here? If it was actually PHY, NetworkManager wouldn’t identify it right?

Some background:

  • This is on a freshly installed Raspbian instance (latest as of 12/25) with the latest eeprom version.
  • I have 4 other devices that work just fine and they were all initially using the same version. I upgraded just now as an attempt to resolve the issue.
  • I already swapped PoE hats with a working device, it’s definitely this device.
  • I tried running rpi-update already and rebooted. Bring up attempt:

~ $ sudo ip link set eth0 up RTNETLINK answers: No such device
