Schenker S306 WiFi Hotkey

Hi,

my Schenker S306 (notebook) suffers from issues regarding WiFi (Intel AC 3160). The keyboard shortcut to toggle WiFi enables a hard & softlock (as observed by rfkill) but when pressing that button again it only removes the softlock.

I did find a workaround. Creating the file:
sudo nano /etc/modprobe.d/wifi.conf
adding the line:
blacklist wmi
and rebooting the system.

But this points to a different/deeper issue with wmi events for this particular machine, and if possible, I’d like to report that issue as well.

Please remove the blacklist, then reboot and post the output of ls -l /sys/class/rfkill/ and lsmod | grep wmi. Also install acpid, then sudo systemctl start acpi_listen. Then start acpi_listen and sudo dmesg -w on two different terminals, then press the key on the keyboard, wait 10 seconds, press it again. Post whatever appeared in both terminals after you pressed the key for the first time.

ls -l /sys/class/rfkill/
insgesamt 0
lrwxrwxrwx 1 root root 0 19. Okt 07:57 rfkill0 -> ../../devices/pci0000:00/0000:00:14.0/usb1/1-3/1-3:1.0/bluetooth/hci0/rfkill0
lrwxrwxrwx 1 root root 0 19. Okt 07:57 rfkill1 -> ../../devices/pci0000:00/0000:00:1c.0/0000:01:00.0/ieee80211/phy0/rfkill1

Surprisingly
lsmod | grep wmi
was empty.

Despite having acpid already installed
systemctl start acpi_listen
returned
Failed to start acpi_listen.service: Unit acpi_listen.service not found.
Reinstalling acpid did not solve that issue.

I should’ve specified, but acpi_listen is not a systemd service, it’s a program, so you should’ve just run it.

I fixed the issue. I don’t need to launch sudo systemctl start acpi_listen but instead just sudo systemctl start acpi.

Okay, apparently there is a difference between desktop environments. Yesterday I changed from XFCE to Plasma, and now the WiFi only irreversibly hardlocks when toggling bluetooth.

Regradless:

For the (in Plasma working) WiFi switch:
