Status update finally I was able to fix this issue upstream see: https://bugzilla.gnome.org/show_bug.cgi?id=733105
But it is only completely fixed in network-manager 1.0 If you want to fix something for ubuntu 12.04 or ubuntu 14.04 you can use my latest local patches. Note: that in ubuntu 14.04 there is also a bug in the wpa_supplicant which can lock up the radio work queue, which makes any further WiFi connections impossible. Fortunately that must have been fixed in the meantime, because I found a fix in the upstream wpa_supplicant repository. ** Bug watch added: GNOME Bug Tracker #733105 https://bugzilla.gnome.org/show_bug.cgi?id=733105 ** Patch added: "updated network-manager patch for ubuntu 12.04" https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1181964/+attachment/4523004/+files/network-manager-wifi-fix.diff -- You received this bug notification because you are a member of Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1181964 Title: Wireless connection does not re-connect To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/network-manager/+bug/1181964/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
