Description Luca Versari 2021-03-09 15:17:45 UTC
I'm having trouble getting the ath11k_pci wireless driver to work with
my laptop.

Relevant part of lspci -v output:

Kernel version: 5.10.13-arch1-1 (I also tried with 5.11.2 with
similar (lack of) success).

dmesg output after running modprobe ath11k_pci:

[  466.214800] ath11k_pci 0000:6d:00.0: WARNING: ath11k PCI support is
experimental!

However, despite the (apparently successful) module loading, no
wireless interface appears.

The module works correctly in Windows.
Comment 1 Xavier Bestel 2021-05-18 08:08:03 UTC
Same same. I'm using 5.11.0-21.2-liquorix-amd64 from https://liquorix.net/ which used to work until the last versions (1 or 2 weeks ago). Wifi & BT are gone now.

Anything I could provide to help ?

(It does for me)
Comment 4 Luca Versari 2021-05-20 07:44:37 UTC
Using 5.12.5 does not seem to fix the issue for me.

Some events from my dmesg:

Oh my bad !
Wifi works well but Bluetooth still doesn't work.

Are you sure this is the same problem as the original reporter? This bug report is about ath11k not working on XPS 9500 since v5.11.2.

I suspect your comment applies to bug #213055 instead, which is about a regression in v5.12.3 stable release.

Hi, I am the author of: bus: mhi: core: Process execution environment changes serially [ Upstream commit ef2126c4e2ea2b92f543fae00a2a0332e4573c48

We do not see progress as https://git.kernel.org/pub/scm/linux/kernel/git/torvalds/linux.git/commit/drivers/bus/mhi/core?h=v5.13-rc2&id=4884362f6977fc05cbec736625665241c0e0732f is missing in the older kernels.

It's meant to be a dependency but was not picked.
Comment 9 Jesper Falk 2021-05-24 12:12:37 UTC
I can confirm that the current build of 5.13.0-rc2 have the driver working on the Dell XPS 9500 (using self compiled kernel in Arch).

I tested the answers in https://bugzilla.kernel.org/show_bug.cgi?id=213055 but none of the kernels mentioned seems to work for me.

St least it´s fixed for the next release then.
Comment 10 Xavier Bestel 2021-10-13 16:14:51 UTC
I have a strange behavior, with my XPS 9500 with a QCA6390:
- after installing 5.14 from Debian, the wifi card "died", i.e. it's as if it's not plugged anymore, can't see it from Linux, from Windows nor from the BIOS
- I called Dell and made them change the motherboard + wifi card; we checked it all worked with Windows, the Dell repairman went away
- as soon as I rebooted under Linux the wifi card was gone again, and no amount of reset/poweroff/whatever made it reappear (also absent from Windows and BIOS)

I had the same problem, minus the back and forth with Dell. What fixed it is :
- deactivate wifi + bluetooth in bios
- boot normally
- reboot
- reactivate wifi + bluetooth in bios
Comment 12 Xavier Bestel 2021-10-19 09:35:35 UTC
I was not sure so I tried exactly that, but I still don't have my WiFi back :/
Just to be sure, there's no WiFI/WLAN in "integrated devices", I found it under some kind of "connections" topic, and there I disabled WLAN and Bluetooth. Was it the right options ?
Comment 13 Xavier Bestel 2021-10-19 13:03:23 UTC
My bad, it works if I do an actual poweroff between BIOS settings. Thanks a lot !
Anyway that's a problem with the driver/hardware, because the OS is unable to get back to the WiFi card once it's in this soft-bricked state ...
