My system: Asus X450CA runnning Lubuntu 15.04. Case 1: The laptop not connected to anything else. I close down the lid, the laptop goes to sleep. I open the lid, the laptop wakes up. And the Wi-Fi seems to work okay afterwards.
Case 2: The laptop connected to an external HDMI monitor (i.e. dual-head setup). This way, closing the lid does not make the laptop sleep. I can press Fn+F1 to start the sleeping procedure. Afterwards, I can press the power button to wake the laptop up. After it wakes up, Wi-Fi does not work anymore, and I need to run "sudo service network-manager restart". In both cases, I have LXDE environment, with OpenBox and xfce4-power- manager. I have not tried too many variations, though; but I hope this helps reproducing the issue. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to dbus in Ubuntu. https://bugs.launchpad.net/bugs/1439771 Title: wpa_supplicant[874]: dbus: Failed to construct signal after 'suspend' Status in dbus package in Ubuntu: Confirmed Status in systemd package in Ubuntu: Confirmed Bug description: The Wifi network can't connect after the wake up from suspend.
