FreeBSD has 802.11ac.

But that is still for a limited number of chipsets though right? I would absolutely love to see way more support. I remember awhile back the FreeBSD Foundation putting some serious (on their scale of funds) funds to WiFi.

		I can't remember which chipsets support it. But yes, the FreeBSD Foundation has been putting a lot of money into laptop support, including wifi improvements.
