One of two identical NICs is unclaimed after disconnecting with applet












0















I have AsRock X399 Taichi motherboard, with two ethernet cards and one Wi-Fi. I used a default network applet from Ubuntu Mate 18.04 to disconnect from the ethernet (to only have Wi-Fi connection) and it caused the network card to be unclaimed.



I’ve tried removing all udev rules from /etc/udev/rules.d and reloading the kernel’s module for the card, but to no success. I also cannot add it manually using said applet (it doesn’t show that card) nor can I ifconfig up it.



Both NICs work just fine on LiveCD.

  • Did you try sudo modprobe -rv igb and sudo modprobe -v igb to see if that makes any difference?

  • Yes. It doesn’t. I suspect that the applet added some config setting, which I can’t find, that turned off the NIC for good.

  • I assume you meant /etc/network/interfaces, if so → auto lo n iface lo inet loopback (used n as a symbol of new line, since comments are one-line-only).
