Airport software upgrade will not recognize Macbook specs

[garyaedgar]

I recently had to replace my logic board and when I did that I also upgraded my hard drive. I just tried to install the airport extreme upgrade to allow N wireless but it told me I didn't have the right hardware. I know I have a dual core 2ghz Macbook from 06 and as far as I can tell that meets the requirements.

Is there something I'm missing or something I can do to resolve this?

Thanks
