[spatular]

I have XPS13 with Killer wifi (Atheros QCA6174). At first there were stability problems but they were completely solved with FW update from Atheros's github repo and a kernel update (to >= 4.9 I think).

Later it turned out that an Intel 8260 card I've bought to use in PC-based AP cannot be coerced to work in 5GHz band no matter what I did, so I've swapped them, now Atheros is in AP and Intel is in XPS, with everything working flawlessly. So it turned out that the Intel card is less functional...
