This is something you need to ask Ubuntu, or check from their git history or package changelogs. But in general distros make changes to the kernel, some of them even quite drastic, so behaviour between distros can be different. My guess is that Ubuntu had custom changes to ath11k, maybe they backported patches? > And finally, do you have a working configuration with wifi and > Bluetooth? if that is the case could you tell me your distro, kernel, > firmware, system firmware versions? I also use Dell XPS 13 9310 with QCA6390 as my daily driver (no pun intended) and I have no issues with wifi. BIOS is 3.1.0 from 07/22/2021. I'm a debian guy so I have Debian 10 and use connman, but network-manager should work as well. I compile my own kernel from my ath.git master branch[1], but with QCA6390 I would expect stock v5.16 release to work fine. For WCN6855 I recommend to use v5.17. Firmware version is WLAN.HST.1.0.1-05266-QCAHSTSWPLZ_V2_TO_X86-1. I don't use Bluetooth so can't comment on that.
