My machine is a Dell XPS 15 9570 with an Intel Wireless-AC 9260. Worked fine with Kubuntu 19.04 and 19.10. Later on on 19.10 (I believe 5.3.0-51-generic) I got loads of hang ups and Wifi drop outs (seconds to minutes). Thought it was the swappines problem or the wifi problem of the kernel. Was adventurous and upgraded to Kubuntu 20.04 pretty early. Wifi went from bad to terrible to not usable (5.4.0-28-generic)
A few days ago installed the mainline kernel following this instruction. How to upgrade kernel to latest version on Ubuntu 20.04 Focal Fossa Linux https://linuxconfig.org/how-to-upgrade-kernel-to-latest-version-on-ubuntu-20-04-focal-fossa-linux Because the kernel is not signed I had to disable secure boot in the UEFI. Got to sign the kernel later on... Now running 5.6.7-050607-generic since a few days and am quite happy. Snappy system, reliable WiFi.
