[SOLVED] Ethernet Expansion Card + Ubuntu Server

Hello there,

I had an issue with a brand new Ethernet Expansion Card + Ubuntu Server 22.04 (+ 11th gen mainboard, but I am not sure it makes any difference) for my Ethereum node.
Since I received a new 13th gen mainboard, I tested it again on Windows 11 and noticed it worked flawlessly. So I gave it another go on Ubuntu.

lshw -C network was showing the interface as DISABLED. So I:

  1. Copied the interface name to the clipboard (enx9cbf0d001857 in my case)
  2. Edited /etc/netplan/00-installer-config.yaml to add this new interface:
network:
  ethernets:
    enx9cbf0d001857:
      dhcp4: true
  version: 2
  1. Applied the changes: netplan apply

And voilĂ !
