[ruihu908]

I have got Acer Aspire 3680-2472, I installed new Mac OS, but every functions was ok except that wireless and ethernet not work. hope some instruction and help! (Since i am not a geek, and I don't, I mean almost never used osx much before ... so plz tell me step by step.and with simple words, lolz. thx a lot )

 

Intel Celeron M 520 1.60GHz 802.11b/g Wireless 1GB DDR2 120GB HDD Dual Layer DVD RW 14.1 WXGA

the Mac leopard (idkois or something) doesn't detect my PCI card.. says no airport card install.

 

transmitter module:BCM94311MCG broadcom

the sound and everthing works i think. All i need is the internet working and everything is to go.

 

PLZ HELP!! thanks

 

Update:

Just checked again.. when i click the Network tab, it says AirPort and Ethernet Adaptor... any ideas??
