We found that after a resume / suspend cycle the interface goes back to work if it is put in promiscuous mode. This was found by accident while running tcpdump to see if there was traffic going through.
This can be tested afer resume with: 1. ifconfig eth0 promisc activate interface in Network Manager .... will work 2. deactivate interface in Network Manager 3. ifconfig eth0 -promsic activate interface in Network Manager ... will fail Therefore, the problem can be worked around by creating /etc/pm/power.d/10_eth0_promisc with ---------------------------------------- #!/bin/bash ifconfig eth0 promisc ---------------------------------------- and give this file execution permissions. This will ensure that after resume the interface comes up in promiscuous mode. -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/771857 Title: Realtek 8168B (r8169) interface not working following suspend To manage notifications about this bug go to: https://bugs.launchpad.net/linux/+bug/771857/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
