Disabling Powersave in NetworkManager did it for me. I was barely getting 300kB/s on certain workloads on my 2.4GHz network whereas I could get full speed on my 5GHz one. By disabling the power management in NetworkManager, I got full speed all the time and I haven't really noticed any decrease in power consumption.

Running Ubuntu 16.04.2, Kernel 4.10 (HWE branch). Stock installation done just a few minutes ago.

02:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32)

Doing the following will disable power saving in Network Manager by default:

$ sudo sed -i 's/wifi.powersave = 3/wifi.powersave = 2/' /etc/NetworkManager/conf.d/default-wifi-powersave-on.conf
