I'm seeing this on saucy, too. "service network-manager restart" fixes the problem. I'm using a Dell Latitude E6400 with iwlwifi.

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/network-manager/+bug/1027202/+subscriptions -- Mailing list: https://launchpad.net/~desktop-packages Post to : desktop-packages@lists.launchpad.net Unsubscribe : https://launchpad.net/~desktop-packages More help : https://help.launchpad.net/ListHelp
