I'm not sure if this is the same bug, but after upgrading to 15.04, I have to "sudo systemctl restart NetworkManager" to get back my network interfaces after a long suspend. If I test a short suspend/resume cycle, like a couple seconds, it works fine, but when I open my laptop in the morning I have to restart NetworkManager.
I attached a journalctl excerpt; I closed the lid last night at 20:29, then opened it this morning at 08:09 and first tried the hardware switch, then eventually restarted NetworkManager. ** Attachment added: "journalctl-networkmanager.log" https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1448555/+attachment/4392723/+files/journalctl-networkmanager.log -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1448555 Title: network-manager does not autoconnect to wifi network after resume from suspend Status in network-manager package in Ubuntu: Confirmed Bug description: After upgrading to 15.04 network manager does not reconnect to the wifi network after resuming from a suspend to memory.
