Wifi hw is also an issue for surface pro 4 (under windows and Linux both). Apparently ms finally fixed in the 5th generation.

Anyone know if there's any really great wifi cards internal or USB, that allows full AP, "war driving" etc - and also 5ghz and such? Preferably with great drivers for Linux and freebsd?

(I doubt internal is an option for my surface pro 4, but for refurbished ThinkPads/dells it might do the trick..)

XPS's Atheros QCA6174 works fine with recent FW. I use it in AP mode in 5GHz band in ac mode, though I had to adapt a kernel patch from OpenWRT that ignores frequency regdomains. I've also tried to use Intel 8260 for this, but with no luck.
