Getting to the Wi-Fi Card
I was still not at the Wi-Fi card! Beneath the main circuit board is a grounding/protector plate. This is easy to remove, and only requires the removal of three more screws, as indicated with red X's in Figure 5. Once these screws are out, you first have to take out the plastic black piece, which then allows the silver shield to be removed. I could finally see the Wi-fi card, which simply lifted out the PSP. As I had hoped, the antenna was indeed connected to the card via a socket connector. In addition, I also noted that my WNICs hardware address was stamped onto the cards surface. Finally, I also should note that the Duo stick slot is also integrated into the same circuit board as the WNIC.
