Wireless not working after replacing network card and screen

I have replaced the wireless/Bluetooth card in my laptop and the Bluetooth works but the wireless does not. I have replaced the display and still not working. Was told that maybe an inductor coil needed replaced. Can anyone shed any light on this and maybe direct me to the best way to get this done?

Is this a good question?

You will need a soldering iron, hot air station (preferably), tweezers, solder and flux (possibly more if I have forgotten something).

If you have experiencing microsoldering, buy this stuff first and we can go about diagnosing the board (sounds like the inductor L3404 to the right of the wifi/bluetooth connector has burnt possibly). Also, send a picture across of this area, usually with wifi issues the inductor is physically burnt.

If you don't have any experience, I would highly recommend sending it somewhere.

Thank you for the info. I do not have any experience soldering. Do you have any suggestions on where to send it, would the Apple Store be able to fix it? Thanks


The Apple shop will just quote replacement of the logic board (very expensive), they won't offer repairs to the logic board.

Depends on where you are located. If you are in the US, Google "Louis Rossmann" and you will come across his website. If you are in the UK, click on my name to see our website. Anywhere else, I am not entirely sure where would be best to send it, but make sure they have good reviews and can carry out logic board repairs.


Thank you so much for you help. I live in the US so I found Louis Rossmann's website and will check with them. Thanks again
