Description Sebastian Turzański 2023-07-19 06:28:26 UTC

On Dell XPS 9700 I have a Dell WD19 dock.

It used to work fine. 
Now when I have e dock station connected with the cable there WIFI is disabled as it should

When I unplug Ethernet cable from the dock the wifi remains OFF and RFKILL shows hard block.

When I plug the Ethernet cable back to the dock the wifi comes up for 2-3 seconds and sets up a connection and then I get e message that wifi gets disabled and connection is switched back to Ethernet.

It used to work fine that unplugging the cable from dock would bring the wifi up.

So having a dock station it is not possible to disconnect its ethernet and have laptop enable Wifi.

It works ok in Ubuntu.

Do you know when it worked?  You can find some old TW kernel packages from TW history repo
  http://download.opensuse.org/history/
and you can install with zypper install --oldpackage option, and test with it.

If it's a kernel regression from 6.3 to 6.4, check the behavior with the latest kernel in OBS Kernel:stable and 6.5-rc kernel in OBS Kernel:HEAD.  If none works, we should report the bug to the upstream.

If 6.3.x kernel also shows the problem, you can try my old kernel packages in OBS, e.g. OBS home:tiwai:kernel:6.2, home:tiwai:kernel:6.1, etc.
Note that those are unofficial builds, hence you'd need to turn off Secure Boot.
