I'm facing the same bug while running 16.04 on a Dell Vostro 3558 (iwlwifi).
I edited the file /lib/systemd/system-sleep/wpasupplicant and changed the bit that goes '/sbin/wpa_cli resume ;;' to 'systemctl restart network-manager.service ;;'. Now when I resume from suspend, at first the network is disabled but in a few seconds, network manager restarts and my wi-fi connection reconnects.
