If unloading-and-reloading the r8169 module solves the problem for you, here's a workaround that does it automatically for you upon resume from suspend:
1) Create a file /etc/systemd/system/fix-r8169.service with the following contents: #### BEGIN FILE #### [Unit] Description=Fix RTL-8169 Driver on resume from suspend After=suspend.target [Service] User=root Type=oneshot ExecStartPre=/sbin/modprobe -r r8169 ExecStart=/sbin/modprobe r8169 TimeoutSec=0 StandardOutput=syslog [Install] WantedBy=suspend.target ##### END FILE ##### 2) Execute the following command: sudo systemctl enable fix-r8169.service Cheers! -- 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/ubuntu/+source/linux/+bug/1752772/+subscriptions -- ubuntu-bugs mailing list [email protected] https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
