Firstly your WN821N (an 11n NIC) won't support 11ac anyway. Newer wireless protocols aren't just "a mode" but a whole set of things are needed from the hardware and driver and 802.11 stack to support them - different radio modulation, features like frame aggregation, block ack, etc. >> FreeBSD already has code for 802.11n/HT support in their fork of >> the rtwn driver, which has significantly diverged over years. > > I will give FreeBSD a spin, although my preference is to run OpenBSD. I think that was a hint as to where to look if wanting to work on the OpenBSD driver for WN821N to support 11n. (11n will be a huge improvement over 11g - obviously not as good as a full 11ac implementation but still fairly usable - in large part due to the additional features rather than modulation). BTW if you can find one, the white Raspberry Pi branded adapters are not a bad choice for USB wifi: https://thepihut.com/cdn/shop/products/official-raspberry-pi-wifi-adapter-discontinued-raspberry-pi-101591-2257829828_1000x.jpg -- Please keep replies on the mailing list.
