Answer to: What is this wire for?It's hard to see perfectly from the picture but that appears to be a piece of coaxial cable that connects the wifi module to the wifi antenna. The two solder points at location 1 are for the coax shield and the inner conductor itself. That "sticker" at Location 2 is the wifi antenna. Not sure what your options are, but I would unsolder at the board. Don't peel the antenna up. If it tears, your wifi reception will be diminished.
