Hi all,
My MacBook has the "Wifi:No Hardware Installed" problem which is due to a failed component on the logic board. Please help me identify the parts marked in the attached pictures so I can replace them.
Upper is how it's supposed to look, lower is my board.
Any help would be greatly appreciated!

soerenfi, this answer is only to identify your components not to diagnose what shorted those out.
Reference designator C3422 is a 0.1uF 10V 20% capacitor in a 402 package.
Reference designator L3404 is a FERR 120 ohm 1.5A filter in a 0402 package.

Just an update since I noticed I forgot to report back: in December 2015 I replaced the capacitor and filter, which brought the wifi back to life and it's still working today!
I assume someone put in the wifi card connector the wrong way and shortened out these two components originally.
