I've found a solution that seems to be quite similar to the one submitted by John Cooper but which relies on other commands to stop network-manager at suspend (hibernate) time and to start it at resume time in order to have the connection reactivated.
Anyway, it works well for me under Kubuntu Dapper, freshly dist- upgraded. Here it is if you want to try it in case the other one doesn't work: Just create these 2 files and be sure to make theme executable (chmod +x): /etc/acpi/suspend.d/07-network-manager.sh #!/bin/sh /etc/dbus-1/event.d/25NetworkManager stop and /etc/acpi/resume.d/99-network-manager.sh #!/bin/sh /etc/dbus-1/event.d/25NetworkManager start Good luck! -- Doesn't bring the network back online when resuming from suspend / hibernate https://launchpad.net/bugs/40125 -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
