I have a Sony QX10 camera, with comes with built-in wifi. I want to to connect wired ethernet to it. I was hoping I could find a wifi chip inside the camera, and solder to where the ethernet traces go into the wifi chip. Here's what the motherboard looks like, -- several chips I could not identify, and none that are obviously wifi. I've added labels on the chips that are to small to read in white.
There's also a teardown video of a similar model here: http://youtu.be/aH0_dAtKofw .
I could not find any other chips or antennas elsewhere in the camera that were obviously related to wifi. Should there be an obvious antenna somewhere?
Is it possible that wifi is integrated into the large processor IC itself?
