I got a D420 (dell latitude) running fine OSX 10.6.7
My problem is i installed the osx with an intel 3945 wireless card (not recognized) and then
i purchased recently a generic broadcom 4311 to use it.
the card is seen in the bios, i covered the pin 20, the osx see the card (with OSX Tools utility as 14e4:4311 ), i fiddle a lot with the IO20211 kext (installed ) changed the en0 to en1 in NetworkInterfaces.plist, but no way, i cannot get the Airport stuff to be detected as network card.
in network i got also Bluetooth, Firewire and the wired ethernet, all working fine.
when i use the System Profiler i see Airport (under network) , with the IO80211 Family 3.1.4(314.1.1) loaded, but in Hardware, i see only one ethernet card (the Apple BCM575 on en0).
when i check logs, it seems the IO20211 kext failed to load AppleAirPortBrcm4311.kext (libkern/kext) dependency resolution failure.
this could means something is missing or not the right version, but i have absolutely no clue about the cause.
Any Idea ?
