This issue disables both wired and wireless connections, and it only happens about every second suspend/resume cycle on my machine. For the remaining cycles, networking comes back up fine after resume.
If the original bug reporter does not reply, I'm willing to follow the testing instructions Christopher posted. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1027202 Title: Does not connect (to wired network) after suspend Status in “linux” package in Ubuntu: Incomplete Bug description: I work with Xubuntu 12.04 on a MacBook Air 4,1. I can easily connect to the internet (wired network / auto ethernet), but after I put the laptop to sleep/suspend, nm-applet is gray and I can't connect to the internet anymore. Rebooting solves the problem. This seemed to be related up to the fact that it was a wireless connection (which always worked fine for me): https://bugs.launchpad.net/ubuntu/+source /network-manager-applet/+bug/704756 ProblemType: Bug DistroRelease: Ubuntu 12.04 Package: network-manager-gnome 0.9.4.1-0ubuntu2 ProcVersionSignature: Ubuntu 3.2.0-26.41-generic 3.2.19 Uname: Linux 3.2.0-26-generic x86_64 NonfreeKernelModules: wl ApportVersion: 2.0.1-0ubuntu11 Architecture: amd64 CRDA: Error: [Errno 2] No such file or directory Date: Fri Jul 20 20:33:05 2012 EcryptfsInUse: Yes InstallationMedia: Xubuntu 12.04 LTS "Precise Pangolin" - Release amd64 (20120425) IpRoute: default via 178.83.94.1 dev eth1 proto static 169.254.0.0/16 dev eth1 scope link metric 1000 178.83.94.0/23 dev eth1 proto kernel scope link src 178.83.94.48 metric 1 NetworkManager.state: [main] NetworkingEnabled=true WirelessEnabled=false WWANEnabled=true WimaxEnabled=true SourcePackage: network-manager-applet UpgradeStatus: No upgrade log present (probably fresh install) nmcli-dev: DEVICE TYPE STATE DBUS-PATH eth1 802-3-ethernet connected /org/freedesktop/NetworkManager/Devices/2 eth2 802-3-ethernet unavailable /org/freedesktop/NetworkManager/Devices/1 eth0 802-11-wireless unavailable /org/freedesktop/NetworkManager/Devices/0 nmcli-nm: RUNNING VERSION STATE NET-ENABLED WIFI-HARDWARE WIFI WWAN-HARDWARE WWAN running 0.9.4.0 connected enabled enabled disabled enabled disabled To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1027202/+subscriptions -- Mailing list: https://launchpad.net/~kernel-packages Post to : kernel-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~kernel-packages More help : https://help.launchpad.net/ListHelp
