have runned ASD and there were no problems with that. Have tried other lcd and still no wifi. Installed new OS X and still nothing.

Tested the connector on the board....
Got 5V on L3404? Check continuity from pin 1,2,4,5,7,8,10,11,12 to the connector on the APX card.

Yes i got 5V on L3404.

Pin 1 0.378

What is AP_RESET_CONN_L measuring?

 

[larossmann]

also tell me the tape is present over the pins. If the tape is not over the pins but that fluffy-thingie-that-sticks-to-the-cable-to-keep-interference-away is there it'll short the pins on the wifi connector.

I assume this was measured with the cable plugged in, else pin 1 and 2 would read nothing.
Don't you find it strange that pin 10 is shorted to GND???

Also if you want a reply to a post you should not "comment" on my post but "reply"

Pin 10 is shorted to ground only when i connect the connector and i have tested a many lcds with good connector and still it says that is shorted. And yes i measured with cable plugged in and without cable.

Pin 10 to GND with connector inserted is correct. Please answer Louis's questions too.
Post measurements without cable inserted too.
Are C3430/31 L3401 looking ok?
Did you actually check if all pins have continuity to the connector on the airport card? 1 2 4 5 7 8 11 12 13? The common failure here is a fucked up connector on the board or a missing cap or coil.
