I’ll try, however my coding skills are truly woeful :-). I have access to 
devices with BCM4331 and BCM43224 (I’m a convert from the Mac world), as well 
as older ones to make sure I don’t break anything.

Nope, it’s not. b43 can do 11n for sure, not sure about 11ac or others. b43 is 
a much more capable driver than the wl STA driver, and is also open (as opposed 
to the STA which is sort-of, kind-of open depending on who you ask).
