I discussed this thing on #ubuntu-devel. Apparently it has something to do with Broadcom WLAN chips or drivers as it seems to be unreproducible on Intel chips. Would it be possible to make Broadcom drivers unload before going to hibernate as it will help to avoid many problems?
User workaround: Create file /etc/pm/config.d/unload_module and put "SUSPEND_MODULES="brcmsmac" into it. -- You received this bug notification because you are a member of Ubuntu Touch seeded packages, which is subscribed to network-manager in Ubuntu. https://bugs.launchpad.net/bugs/1439771 Title: wpa_supplicant[874]: dbus: Failed to construct signal after 'suspend' Status in network-manager package in Ubuntu: Confirmed Bug description: The Wifi network can't connect after the wake up from suspend.
