FWIW, I tried most things suggested here and elsewhere, like replacing all the QCA6174 firmware files with what is in https://github.com/kvalo /ath10k-firmware and upgrading to the yakkety version of linux-firmware (1.158 as of the moment). Even with all that, in order for wifi to work on my laptop, I still have to replace "/lib/firmware/ath10k/QCA6174/hw3.0/board.bin" with a version from Killer Networking's website, as per:
http://www.killernetworking.com/product-support/knowledge-base/17-linux The required file is directly available at: http://www.killernetworking.com/support/K1535_Debian/board.bin The machine is a Dell Latitude E7270.
