[SOLVED]Macbook Pro 13 A1425 no wifi

[Ciki]

Board was water damage and has bios issue ,reprogram the bios and everything working ok ,just no wifi .Bluetooth working ,just no wifi I mean doesnt see wifi card at all ,not talking about signal

Known good IO board and cable?

 

[Ciki]

Dont have to test another one ,I have wifi card from A1502 can try it or just will not work

 

[dukefawks]

It's not the card of course. Get a known good IO board and flat cable. I believe the A1502 card may work for testing, will only work in OSX not in the boot menu.

tried new cable ,board, card still missing wifi_event

 

[dukefawks]

wifi_event is supposed to be low.
Inpsect J4410 for corrosion and do diode mode test on all PCIE_AP lines.
