WiFi problem - Intel AC 9260 - drivers

Hello,

I can't switch wifi interface up with the latest linux-firmware. The problem is about iwlwifi drivers and similar to the problem described in https://bbs.archlinux.org/viewtopic.php?id=249888 which is flagged as solved. There is also a bugtracker entry https://bugs.archlinux.org/task/63117 flagged as closed but it still persists.

I'm using an Intel 9260 card. I couldn't get it working on latest linux-firmware with either 5.6.15 or 5.7.5-zen. Yet, it works with both kernels after downgrading to linux-firmware-20190717.bf13a71. I tried 2020 05 19, 2020 04 21, 2019 12 10 along the way with no success. You need to download corresponding file from https://archive.archlinux.org/packages/ … -firmware/ and install it with pacman -U as directed in the first message in the bugtracker.

I was getting

Direct firmware load for iwl-debug-yoyo.bin failed with error -2

with dmesg | grep iwlwifi

ALSO,

nl80211: Could not set interface 'wlp2s0' up

along a memory dump with wifi-menu

Re: WiFi problem - Intel AC 9260 - drivers

Don't be vague, post the errors and dumps you are getting, neither of the things you point out do necessarily point to an issue. (that firmware load failure is most likely  irrelevant, and not being able to up the interface can have a wide variety of benign causes, like the interface already being up)

You talk about "similar issues" do you get the same trace, with the GEO messages at the end? If you don't you likely have a different issue.

FWIW maybe post:

find /etc/systemd -type l -exec test -f {} \; -print

If you want to report a firmware bug your best bet is reading https://wireless.wiki.kernel.org/en/use … /debugging and trying a few of the things there to generate better output, also pay attention to the later firmware debugging sub-topics

Re: WiFi problem - Intel AC 9260 - drivers

I won't bother debugging a problem that was already well documented. There is clearly an issue with the driver.

Where this relates to Arch is, that driver is recently updated in linux-firmware version 2020 06 19 https://git.kernel.org/pub/scm/linux/ke … 971db5494e but the package has not been updated in arch repos, still on broken 2020 05 19.

So you know the root cause of the issue and you're basically asking when the linux-firmware package will be upgraded?

I only noticed the updates after having to make a few more searches for linux-firmware changelogs after that somewhat aggressively toned reply.

And for now, yes either that, or a link describing how I can load the driver in that update without messing up my whole system I've been trying to set up for 3 days.

Re: WiFi problem - Intel AC 9260 - drivers

If I understand your initial post correctly, you worked around your issue by downgrading to linux-firmware-20190717.bf13a71.
Why not just do that and wait for the packagers to release the updated package when it is ready.

Re: WiFi problem - Intel AC 9260 - drivers

Because it took me 3 hours to find a solution and another hour to apply it. I had to try multiple firmwares and multiple kernels before finding an "ideal" solution. I thought this would save some time and frustration for other people who might think this issue was long gone and problem is something else, of which even the mod implied btw.

Yes, I'll be waiting for the release and update this thread. Thank you.

How have you determined the issue is purely a firmware issue and not a bad combination of kernel driver and firmware?
