Description:

The latest core/linux package from Archlinux doesn't load the iwlwifi module and the wi-fi card is not recognized, as discussed in [1]. Applying a patch from Manjaro[2] in core/linux 4.17.3 fixes the problem.

[2] https://gitlab.manjaro.org/packages/core/linux417/blob/master/0001-iwlwifi-killer-ac-1550.patch

Additional info:
* core/linux 4.17.3-1 and also reproduced in 4.16
* "Killer(R) Wireless-AC 1550 (9260NGW)" as "Network controller: Intel Corporation Wireless-AC 9260 (rev 29)" in lspci
* Laptop Alienware 15 R4

Steps to reproduce:
- Have a Killer/Wireless-AC 9260 wireless card
- Install latest core/linux 4.17.3-1
- Reboot
- Run "ip a" command and the wireless card is absent

I can confirm that this bug existed for me and this patch fixed it.

Before the patch, dmesg had no relevant output. Post-patch, it shows as follows:

[ 1.866990] iwlwifi 0000:03:00.0: enabling device (0000 -> 0002)
[ 1.870729] iwlwifi 0000:03:00.0: loaded firmware version 38.c0e03d94.0 op_mode iwlmvm

[ 2.158609] iwlwifi 0000:03:00.0 wlp3s0: renamed from wlan0

I've attached my lspci output for additional info.

I also have the same problem. After updating the patch package, it is normal; the kernel in the official repository does not have the pci information of killer 1550.

Did anyone contact the linux-wireless mailing list http://vger.kernel.org/vger-lists.html#linux-wireless to see if upstream intends to include the patch in the official kernel for 4.19 as it is now too late for 4.18?

I am busy with my work; I have not contacted; sorry.

I contacted them, I'll let you know if I receive a response.

There is a patch here[1] from July 25, 2018, is not exactly the same with Manjaro patch. Apparently the patch is accepted, but I'm not sure in what Linux version.

It means the maintainer of the wireless-drivers subsystem accepted the patch, but Linus has not merged it yet.

I think it has to pass through the netdev tree then mainline then it can be backported to stable.

Missed the 4.17.12-rc1 so earliest stable would be 4.17.13 or the 4.18 series whichever comes first.

Also this is a response from linux-wireless DL:
"From the bug report I see that you are asking about this patch:

0a5257bc6d89 iwlwifi: add more card IDs for 9000 series

https://patchwork.kernel.org/patch/10528929/

It's in wireless-drivers currently and I'll try to get it to 4.18 still
but not sure if it makes it. But it will be in 4.19 for sure (unless
something really surprising happens)."

The wireless card is working fine with the new kernel version: 4.17.14-arch1-1-ARCH
