I had several critical issues with a 2018 Dell XPS 13 w/Ubuntu 18.10 preloaded; namely the wifi would frequently not return after hibernation (needed reboot) and sometimes the entire system wouldn't come back after hibernation. I tried many fixes, including new kernels, to no avail. Finally I upgraded to 19.04 and everything has worked flawlessly for the past 6 months.

Atheros WiFi? I have the same problem with XPS 15, and it seems a Qualcomm firmware bug[1], not a Linux fault. [1] https://bugzilla.kernel.org/show_bug.cgi?id=196649 https://bugzilla.kernel.org/show_bug.cgi?id=196649
