Intel Centrino advanced N-6205 Kext?

I recently got a Gateway laptop (NV57H05h) and have been able to install OSX Snow Leopard to it. Problem is I have no internet, no ethernet or wifi.
I admit I'm a newb to this which is why I cam to you guys for help, does anyone have or know of a kext for the Intel Centrino advanced N6205

Thanks in advance.

PS - I found an Ethernet kext here (http://www.insanelymac.com/forum/index. ... 4987&st=20) I haven`t tested...
