My Acer Aspire E5 575G has a Qualcomm Atheros QCA9377. I have tried reinstalling my kernel, I have reinstalled drivers(ath10k), installing backport, have turned off powersaving, have installed wicd, etc...
only thing that has slightly helped is disabling WMM in the router settings. My kernel version is 4.10.0-42-generic.
Typical speeds right next to the router are 15 mbps up and down. I have a 50/50 plan. 50+ mbps is my ethernet speed. when bluetooth is on, my mbps is half of the current slow wifi.
Here are some of the commands y'all often ask for:
