For what its worth, I've had zero issues with WiFi on my 9380. The "killer" wifi is just an ath10k:

  02:00.0 Network controller: Qualcomm Atheros QCA6174 802.11ac Wireless Network Adapter (rev 32)
  Subsystem: Bigfoot Networks, Inc. Killer 1435 Wireless-AC
  Kernel driver in use: ath10k_pci

As far as I can tell, its no different from any other Qualcomm Atheros WiFi. I believe the "killer" differences are just in the Windows drivers.

That's interesting - the only other issue is that I then can't upgrade to Wifi 6 or whatever, but that's probably not an issue until a few years down the track when all my other devices support the same standard.
