I'm also experience abysmal Wi-Fi performance with QCA6174 on a new Lenovo Yoga 910 - dropping connection every few minutes, reporting very low network strength coverage.
Out of the box, the card didn't work at all with neither Ubuntu Xenial LTS nor elementaryOS 0.4 Loki, but I got it running rudimentarily with the latest hwe-edge kernel 4.10.0.20 and linux-firmware (1.164). I've tried upgrading to the latest firmware packages from github.com /kvalo /ath10k-firmware/tree/master/QCA6174 to fix the poor connection performance of the network card, but it sadly doesn't seem to have had any noticeable effect. I've also disabled the network card power-savings, disabled IPv6, tried all sorts of tinkering with the router, nothing seems to fix the poor performance. A weird quirk I noticed is that if the notebook is completely still, network connection drops less frequently, but if the computer is moved by just a bit, then the network connection drops noticeably. One problem is that the network indicator doesn't even report that the connection has been lost/dropped, the only way it's noticed is the long buffering time it takes suddenly to load websites: sudo service network-manager stop/start fixes this temporarily, but this is far from a solution and very annoying. What can I do to fix this (apart from using Windows :( )?
