i know that wifi adapters never worked in obsd(excluding those
adapters for which drivers were written by vendors), but i found one
that shows signs of life in 11n(11ac 2t2r supported by chip). it can
be bought anywhere where there are samsung tv. moreover it even works
in hostap mode(unlike the buggy athn).
but without a ton of bugs not done:
bwfm0: could not read register: TIMEOUT
bwfm0: could not open rx pipe: IN_USE
bwfm0: could not init bus
bwfm0: firmware did not start up
..and sometimes kernel panic on boot, but works would still!

Wireless Adapter" rev 2.10/0.01 addr 2

it is shown where to solder the wires for wifi. on the right through
two pins(ground is first) is bluetooth, but for obsd this does not
matter(thx theo).
