[SOLVED] atheros / ath10k / QCAxxxx

Atheros fixups that have been lingering for nearly 3 years resolved in 24 hours ... never buy bleeding edge laptop hardware unless you're certified master masochist.

* One line patch to promote tx performance to rx level for 5GHz wifi, 4.9.x kernel. Posted in laptop forum then realized its nubie-centric: https://www.linuxquestions.org/quest...ch-4175648663/

* Also a work around for inconsistent connection/crashes, these go in /etc/rc.local:

Code:

ifconfig wlan0 down; rmmod -vf ath10k_pci; rmmod -vf ath10k_core; modprobe ath10k_core; modprobe ath10k_pci

No idea why it works in /etc/rc.local (did not work as pre-up script with wicd or nm) or why it was so problematic.

* Moved from wicd to NetworkManager. Do not like the nm interface or its crippled applet architecture but connections are up consistently before the xfce splash is done.

Glad to hear you got it working!

I felt your pain

Slackware64 14.2 + MultiLib here ...

Code:

3f:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32)
        Subsystem: Bigfoot Networks, Inc. QCA6174 802.11ac Wireless Network Adapter
        Flags: bus master, fast devsel, latency 0, IRQ 141
        Memory at dc200000 (64-bit, non-prefetchable) [size=2M]
        Capabilities: [40] Power Management version 3
        Capabilities: [50] MSI: Enable+ Count=8/8 Maskable+ 64bit-
        Capabilities: [70] Express Endpoint, MSI 00
        Capabilities: [100] Advanced Error Reporting
        Capabilities: [148] Virtual Channel
        Capabilities: [168] Device Serial Number 00-00-00-00-00-00-00-00
        Capabilities: [178] Latency Tolerance Reporting
        Capabilities: [180] L1 PM Substates
        Kernel driver in use: ath10k_pci
        Kernel modules: ath10k_pci

When I bought this laptop with a Killer Wireless I had to use a firmware file from https://github.com/FireWalkerX/ath10k-firmware

My Killer "Dual Band Wireless-AC 1535 M.2 AC" seemed to 'fix itself' with kernel-firmware-20160511git-noarch so I've not had to use the firmware override for a while.

My wireless is rock-solid with wicd ( Network Manager could never connect and stay connected -- it would go into an infinite loop ).

But maybe I am missing something ... I'll check it out ...

Thanks.
