Public bug reported: After upgrade to 18.04 (bionic) I've encountered the following regression: wired network connection does not work, when system is resumed from suspend.
Reloading the kernel driver module seems to help: sudo modprobe -r r8169 sudo modprobe r8169 Could this be fixed structurally?
