Absolutely not outdated. I had a horrible time getting my hands on a working driver for the WiFi card in my brand new laptop last year. Horrible enough to resort to Ubuntu and even that gave me the finger. When I finally had it working I had to manually rebuild the damned thing each kernel update because I couldn’t convince DKMS to do it automatically. Had to wait two or three kernel releases for the card to be supported ‘out of the box’.
So no, fuck WiFI drivers in Linux. If it is not in the kernel and the manufacturer doesn’t provide one, don’t expect fun times.
