You can't make proprietary driver using firmware of your choice, so don't bother looking at MIPS drivers stored at Larry's server. You just need to find a /complete/ (mostly closed source of course) driver 6.20 for x86/x86_64. I don't think it was ever published on Broadcom's site, I think it was made available to Ubuntu only under some agreement. So keep looking at Ubuntu resources. Also linux-wireless ML focuses on open source drivers, so you may have more luck asking at Ubuntu community. --=20 Rafa=C5=82
