Just upgrade from Xubuntu artful to bionic, and just discovered I face the same issue.
Only modprobe -r r8169 + modprobe r8169 restore the network. For now running default kernek 4.15.0-20-generic. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1752772 Title: r8169 ethernet card don't work after returning from suspension Status in linux package in Ubuntu: Confirmed Bug description: I have noticed that the network stopped working on my desktop after I've suspended the system and woke it up. On dmesg there are messages like: [ 150.877998] IPv6: ADDRCONF(NETDEV_UP): enp1s0: link is not ready [ 150.944101] do_IRQ: 3.37 No irq handler for vector [ 150.944105] r8169 0000:01:00.0 enp1s0: link down [ 150.944180] IPv6: ADDRCONF(NETDEV_UP): enp1s0: link is not ready When using Xenial (from a different install), this problem is not happening. This is happening on Bionic. There are only two ways to restore connectivity: 1) Reboot the system; 2) Remove the r8169 module and reinsert it with modprobe.
