Regarding my previous comment "4.15.0-24-generic resolved the problem for me." That is true for my Asus N53SV laptop.
However I have a desktop motherboard with onboard Ethernet controller: Realtek Semiconductor Co., Ltd. RTL8111/8168/8411 PCI Express Gigabit Ethernet Controller (rev 11) Where I have discovered this issue is occurring on Kernel Linux 4.15.0-43-generic #46-Ubuntu I have made a temporary workaround for my desktop like so: ##### #/etc/systemd/system/fix-r8169.service [Unit] Description=Fix RTL-8169 Driver on resume from suspend After=suspend.target [Service] User=root Type=oneshot ExecStartPre=[[ $(uname --kernel-release) == "4.15.0-43-generic" ]] && /sbin/modprobe -r r8169 ExecStart=[[ $(uname --kernel-release) == "4.15.0-43-generic" ]] && /sbin/modprobe r8169 TimeoutSec=0 StandardOutput=syslog [Install] WantedBy=suspend.target #systemctl enable fix-r8169.service ##### This script gives new kernels the opportunity to get it right. If I update and the new kernel is not working, I'll update the kernel version in the systemd service. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1752772 Title: r8169 ethernet card don't work after returning from suspension To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/1752772/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
