Dell XPS 13 9360 (Kaby lake) using Ubuntu 16.04, kernel 4.4.0-53. Connection drops randomly, while iwconfig and network manager showing as still connected. Disconnecting and reconnecting to the network resolves the problem. Have tried changing wifi-powersave in /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf to '2' instead of '3', but the problem still persists. lspci shows 3a:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32)
