Testing wireless speed with RT-87U 802.11ac router shows that the speed is only 27.3 megabits per second which is very low for an 802.11ac card:
iperf -c rtr

------------------------------------
For comparison, on the same network (from the same distance to the router) I have the following result with an Intel's card (on a 4.8 kernel, different laptop):

200 Mbps is much better.

I tend to blame Atheros firmware so I've tried whatever kvalo has in the ath10k-firmware
https:/ /github. com/kvalo/ ath10k- firmware
sudo rmmod ath10k_pci ath10k_core ath mac80211 cfg80211
# this gets rid of some of the kernel warnings about firmware but the performance remains low
sudo cp ath10k- firmware/ QCA6174/ hw3.0/firmware- 4.bin_WLAN. RM.2.0- 00180-QCARMSWPZ -1 /lib/firmware/ ath10k/ QCA6174/ hw3.0/firmware- 5.bin
sudo cp ath10k- firmware/ QCA6174/ hw3.0/board- 2.bin /lib/firmware/ ath10k/ QCA6174/ hw3.0/board- 2.bin
sudo modprobe -a ath10k_pci ath10k_core ath mac80211 cfg80211
