Hi, my problem is all described in the title, at least I think.
Look at this picture (taken from web)


One sees very well that there's AirPort settings, you can enable and disable ... TO ME THERE IS OWN! : (
My Mac is not an original, only a fool would spend all that money ..

I just installed the MAC on a Windows machine, in this case is a Snow Leopard Mac OS X installed with iATKOS.

All without a hitch, but the wifi I have no idea what to do ..

I looked for in the search, the AirPort Utility, I opened and I was pointing out that networks Apple or Apple's Wi-Fi devices, I do not remember, then it stops and leaves the message that did not find anything .. Please do not know how, I also have the CD with the drivers, however, only part of the windows exe on Mac NO! Do not know how to use the Macintosh, so please explain in detail how to solve (if possible)

Thanks (MY WIRELESS CARD IS: ATHEROS AR5007G

PS: SORRY FOR MY BAD ENGLISH BUT I'M ITALIAN!
