This broke again for me on upgrade from Bionic to Cosmic on the Dell XPS 9380. When it starts to go bad it requires a reload of the driver every 10 minutes or so. The dmesg log says "device successfully recovered, but it fails to rejoin any wifi networks and doesn't work properly until I rmmod ath10k_pci; modprobe ath10k_pci. dmesg logs follow, I'm on the latest 4.4.1 firmware (not sure if I need c1/c2/c3)
