Thank AceLan, I gave it a try, but it seems that those files are the same or older than the ones available on github.com/kvalo/ath10k- firmware/tree/master/QCA6174 and the poor performance remains. I also found a bug from 2015 https://bugs.launchpad.net/ubuntu/+source/linux-firmware/+bug/1520343 , which seems related to this and affects a lot of other people - that bug was originally due to the card not being supported [which has now been fixed], but has developed lately with more comments into the random poor performance of the card under linux. Although, the original poster to this bug has provided more detailed logs for a potential solution. I think it's apparent that there's a real problem with the linux- firmware of QCA6174 and I've personally reached a point where I'm not sure if it's worth riding it out or to jump OS-ship. -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1670041 Title: Poor performance of Atheros QCA6174 802.11ac (rev 32) (Killer Wireless 1535) Status in linux package in Ubuntu: Confirmed Bug description: Update: added some forensics in the paste (a long read): http://paste.ubuntu.com/24118478/ TL;DR with a bit of intuition: We need a new firmware-5.bin from Qualcomm Atheros for this rev 32 card in order to make it work well - if anybody has contacts there it would be nice to ask them to upload this to the upstream linux-firmware tree. 3b:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32) qca6174 hw3.2 target 0x0503 chip_id 0x00340aff sub 1a56:1535 Original message: -- I experience a very poor 802.11ac performance of a QCA6174 Wireless card (Killer Wireless 1535).

[Kernel-packages] [Bug 1670041] Re: Poor performance of Atheros QCA6174 802.11ac (rev 32) (Killer Wireless 1535)
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 :( )? Any recommendations? -- You received this bug notification because you are a member of Kernel Packages, which is subscribed to linux in Ubuntu. https://bugs.launchpad.net/bugs/1670041 Title: Poor performance of Atheros QCA6174 802.11ac (rev 32) (Killer Wireless 1535) Status in linux package in Ubuntu: Confirmed Bug description: Update: added some forensics in the paste (a long read): http://paste.ubuntu.com/24118478/ TL;DR with a bit of intuition: We need a new firmware-5.bin from Qualcomm Atheros for this rev 32 card in order to make it work well - if anybody has contacts there it would be nice to ask them to upload this to the upstream linux-firmware tree. 3b:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32) qca6174 hw3.2 target 0x0503 chip_id 0x00340aff sub 1a56:1535 Original message: -- I experience a very poor 802.11ac performance of a QCA6174 Wireless card (Killer Wireless 1535).
