Hi guys I've got an Acer Aspire 2920 with broadcom BCM5787M.
I tried to add the file in attachment of this post "BCM5722D.kext" in system\library\extesion but after reboot my lan still don't work... .


PC: Acer Aspire 2920 ( Intel Core 2 Duo chipset: intel 965)
Mac Os X: 10.6.6i By hazard

p.s.: I have also tried to install max os x 10.6.2 but the result is the same with this kext my lan don't working.... in mac manager as Ethernet Cards don't result anything.

p.p.s. after added the kext file in library directory displays a message :
System extesion cannot be used
The system extension " /System/library ........." was installed improperly and cannot be used.
Please try reinstalling it....


what's my problem?
thank u guys
