Intel Wireless-AC 9560 - No network device using newer kernel

After installing arch my built in wifi adapter doesn't show as a network device in ip link. On lspci it shows the device as Intel Wireless-AC 9462 and iwlwifi as being the driver in use, but dmesg (iwlwifi messages, full output) shows it loaded firmware but dumps an error log.

The device works when booting off the arch boot thumbdrive I used to install.

I've tried removing and reloading the iwlwifi module, updating linux-firmware to the linux-firmware-git version, and downgrading it to linux-firmware-20191022.2b016af-3-any (same as the thumbdrive image), but this did not resolve the issue.

I also tried updating linux to linux-5.5-rc2, which did not help, but the device appears on ip link and works when downgrading the kernel to the one on the installation image (5.2.13.arch1-1). Downgrading to linux-5.2.14.arch2-1 also works, but anything later than that I have tried does not (5.3.arch1-1, 5.4.5.arch1-1, 5.5-rc2).

Any suggestions would be appreciated.

This bug report looks very similar, but there hasn't bee a response yet. The reporter had success with a 5.3 kernel, though.

There is a second similar issue with a patch, but this was also working with 5.3 and only broke in 5.4:
https://lore.kernel.org/linux-wireless/ … gmail.com/
The bug report referenced in the patch seems to be another issue, maybe the first one I mentioned or even a third issue. https://bugs.archlinux.org/task/64703

Edit: The patch seems to fix the issue with a Dell Vostro 5481, but did not help on a Dell XPS 13 2-in1. (Maybe the 2-in-1 needs this patch, but another one as well or only a different patch.)

Thank you. That issue does seem to be from 5.3 to 5.4, but I will look through it and try the fix.

Re: Intel Wireless-AC 9560 - No network device using newer kernel

Lots of possibly distinct bugs:

1. linux 5.4 AX1650i requiring new firmware now in linux-firmware

2. linux 5.4 iwlwifi.lar_disable=1 causes firmware error https://bugzilla.kernel.org/show_bug.cgi?id=205695

3. linux 5.4 scan config command size Dell Vostro https://lore.kernel.org/linux-wireless/ … gmail.com/

4. linux 5.4 Dell 2-in-1 https://lore.kernel.org/linux-wireless/ … gmail.com/

5. linux 5.3+ this thread

Re: Intel Wireless-AC 9560 - No network device using newer kernel

Thank you for the links. I'm not sure what I did when I tried it yesterday but I tried 5.3 again and now it works, and the issue is with 5.3.13 working and 5.4 not.

The scan config command patch did not work for me, neither did toggling the lar_disable setting.

This which I think you linked in the other bug thread does seem to be the same issue.
