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 Ubuntu Bugs, which is subscribed to Ubuntu. https://bugs.launchpad.net/bugs/1670041 Title: Poor performance of Atheros QCA6174 802.11ac (rev 32) (Killer Wireless 1535) To manage notifications about this bug go to: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1670041/+subscriptions -- ubuntu-bugs mailing list ubuntu-bugs@lists.ubuntu.com https://lists.ubuntu.com/mailman/listinfo/ubuntu-bugs
