Two years later and bug still lurking on this new (to me) laptop. Ubuntu
16.04, Kernel 4.4.0-101-generic, Skylake HM170, nVidia GTX970M, HD530
graphics, USB-C Thunderbolt3, NVMe M.2 Samsung Pro 960 SSD, etc.

3c:00.0 Network controller [0280]: Qualcomm Atheros QCA6174 802.11ac
Wireless Network Adapter [168c:003e] (rev 32), dmesg:

I use the built-in Ethernet and not the built-in WiFi so not a big deal
today. But would still like to see it fixed some day. I intentionally
bought a brand new laptop first released two years ago so it wouldn't
have bleeding-edge bugs :(
