Hi, I installed Ubuntu 20.04.1 LTS on my XPS9310.
Enabled developper updates: with deb http://ch.archive.ubuntu.com/ubuntu/ focal-proposed main restricted universe multiverse and then followed these instructions: https://bugs.launchpad.net/ubuntu/+source/linux/+bug/1879633/comments/43 after reboot the wifi was detected. Unfortunately this is not stable and crashes either immediately or after a few minutes of usage. And usually the laptop freezes after a while and becomes very very hot. Here the kernel logs Dec 22 18:25:06 xps9310 kernel: [ 9.251416] ath11k_pci 0000:55:00.0: WARNING: ath11k PCI support is experimental!
