Public bug reported: After suspending my laptop and resuming it in a different location, the network manager applet was still showing that I was connected to the old (no longer present) wifi network, and would not automatically connect to a new network.
Here's the iwconfig output: $ iwconfig lo no wireless extensions. wlan0 IEEE 802.11abgn ESSID:off/any Mode:Managed Access Point: Not-Associated Tx-Power=15 dBm Retry long limit:7 RTS thr:off Fragment thr:off Power Management:off But network manager believes it's still connected: $ nmcli nm RUNNING STATE WIFI-HARDWARE WIFI WWAN-HARDWARE WWAN running connected enabled enabled enabled disabled ProblemType: Bug DistroRelease: Ubuntu 14.04 Package: network-manager 0.9.8.8-0ubuntu7 ProcVersionSignature: Ubuntu 3.13.0-29.52-generic 3.13.11.2 Uname: Linux 3.13.0-29-generic x86_64 ApportVersion: 2.14.1-0ubuntu3.2 Architecture: amd64 CurrentDesktop: KDE Date: Mon Jun 2 13:16:39 2014 EcryptfsInUse: Yes IfupdownConfig: # interfaces(5) file used by ifup(8) and ifdown(8) auto lo iface lo inet loopback InstallationDate: Installed on 2013-04-05 (423 days ago) InstallationMedia: Kubuntu 12.10 "Quantal Quetzal" - Release amd64 (20121017.1) IpRoute: default via 192.168.1.1 dev wlan0 proto static 192.168.1.0/24 dev wlan0 proto kernel scope link src 192.168.1.34 metric 9 NetworkManager.state: [main] NetworkingEnabled=true WirelessEnabled=true WWANEnabled=true WimaxEnabled=true SourcePackage: network-manager UpgradeStatus: Upgraded to trusty on 2014-05-14 (19 days ago) nmcli-dev: DEVICE TYPE STATE DBUS-PATH wlan0 802-11-wireless connected /org/freedesktop/NetworkManager/Devices/0 nmcli-nm: RUNNING VERSION STATE NET-ENABLED WIFI-HARDWARE WIFI WWAN-HARDWARE WWAN running 0.9.8.8 connected enabled enabled enabled enabled disabled ** Affects: network-manager (Ubuntu) Importance: Undecided Status: New ** Tags: amd64 apport-bug trusty -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1325763 Title: Network manager does not detect a wifi network going away To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1325763/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
