We have to remember that most of the time, those wireless chipsets are integrated into notebook computers, so adding a pcmcia or usb dongle to get wifi is inconvenient, at least.
I'm unaware if ndiswrapper would work in this case.
(sorry for using the thread as rant, this is not intended per se to address the question's author)
That doesn't undermine the fact that most users not only request, but demand their systems working out of the box. And that is partly the fault of pcbsd promesing this illusion. This is not just incosiderate, but rude, and ruder for the fact that the board admins have gone a while now and now most issues are solved with quick hacks or traditonal freebsd troubleshooting from board volunteers who in many cases have little to no patience or tolerance for inexperienced users, which is absolutely fscking understandable.
Those inexperienced users shoud also be aware that even though sometimes they get one or two rude answers, they get them, even though they provide zero to none information. You can't say the same from, say, an ubuntu board ("get the latest festyxyz and make sure insert-no-brainer-excuse-here, reinstall and come back later".
I've already said so, we got no crystal ball, and even though many attempt to figure out whats wrong with one liners such as "my network card doesnt work. wanna wanna. take me step by step, i'm noob. specs compaq with wifi".
I'll end this with a well known rant...
Computers Are Hard
Accept it. Move on. Your life will be much simpler.
Accept that it'll take work. Accept that it'll take learning. Accept that it'll take trial and error. Accept that it'll mean just accepting things without understanding why until further down the road.
I've accepted and paid due price.
