Re: [SOLVED] slow intermittent wireless on AC-8260

What was the version of backports?  I haven't found much for updates on backports in 8 months and that is likely the reason they fail to build on your kernel

Re: [SOLVED] slow intermittent wireless on AC-8260

Just follow the links added by Emmanuel Grumbach in the upstream report at comment 2 (https://bugzilla.kernel.org/show_bug.cgi?id=194643#c2), and you will see the version.

Re: [SOLVED] slow intermittent wireless on AC-8260

The journal log in your bug report did you use journalctl | grep iwlwifi?

Because I don't see any iwlwifi in journalctl though!?

In the lines I quoted originally in the first post in this thread yes I grepped for iwlwifi. In the log attached to the bug report at https://bugzilla.kernel.org/attachment.cgi?id=254849 there are certainly lines with iwlwifi in them! Also see the more recent journal logs in my upstream report which also have iwlwifi lines in them.

This issue has now progressed quite significantly, and the main wireless developer for Intel who replied to my bug report made available the facilities for building new versions of the driver and firmware that include debug hooks - after a few hiccups trying to build the driver I now have wireless AC-8260 working really well in my system with the build and install of the driver achieved with the stock arch kernel - have a look at the more recent entries in the upstream kernel driver bug report to see what led to this success. If all goes well perhaps the patched driver will trickle down into the next series of kernels possibly into the 4.10 series once the driver builds successfully for the next kernel (I know that 4.10-1 is in [testing], but it will be a later 4.10-X at some point when the working version will become part of the stock kernel.  Also I don't know what the differences are between the wireless firmware provided by the developer (Emmanuel Grumbach), and that in the current arch linux-firmware package (currently linux-firmware 20170217.12987ca-2 ).

Re: [SOLVED] slow intermittent wireless on AC-8260

With the latest wilwifi driver built from the git master, and using the replacement wireless firmware file iwlwifi-8000C-27.ucode provided in the upstream report instead of the stock firmware from the current linux-firmware package gives me a nice working wireless connection. At some point presumably these will feed through to the arch packages in the kernel and linux-firmware, but essentially this thread can now be closed as resolved.

Re: [SOLVED] slow intermittent wireless on AC-8260

I made this account to say specifically that this works!
It's the only thing that worked for me. I am on Manjaro.
These are the exact steps I took:

$yaourt iwlwifi (install linux-firmware-iwlwifi-git from AUR)
$git clone git://git.kernel.org/pub/scm/linux/kernel/git/iwlwifi/backport-iwlwifi.git
$cd backport-iwlwifi
$make
#make install
#cp /lib/firmware/iwlwifi-8000C-27.ucode /lib/firmware/iwlwifi-8000C-36.ucode
