To upgrade my 2006 vintage macbook pro intel duo to 802.11n wireless.
Went very well. The photos on your website were fantastic and easy to follow. When finished, the wireless was finally up to speed with my current Airport configuration (802.11n). I would definitely recommend your site to others. Thanks.
Follow the pictures on the website and make sure you have the right tools to get the Macbook open to access the Airport card.
