Hi
On the under side of the logic board(the opposite side of the one in the picture)there is a chip that looks like a SSD(SSD’s highlighted in photo)
[image|2815141]
I believe that is the WIFI chip
I don’t recommend removing this as it requires applying LOADS of hot air onto the board to melt the solder and unadhere the underfill which can reflow things and even worse burn the board
It’s entirely up to you ,so Il let you decide;-)
Hopefully this helps
Any questions please ask
Thanks:-)
