WiFi: No Hardware Installed

Hello,

I am having a very difficult time repairing my MacBook Pro. Here are the exact specs:

MacBook Pro 13-inch Mid 2009

2.26 Ghz Core 2 Duo

8GB DDR3

Running OS X El Capitan 10.11.6

Wifi was working for the longest time. I ran into a few problems and ended up having to completely reinstall OS X. After getting it updated to the latest version of El Capitan that it can run, the Wifi has been showing up as No Hardware Installed. I tried cleaning out the Airport Card and even replacing it, and that did nothing. Reset both SMC and PRAM, no luck. Boot into Safe Mode, run Diagnostic, nothing. The iSight cable is working and not having problems also. I don't mind not being able to use the Airport Card, even though it's weird that only the Wifi isn't working, but when trying to use a Mac supported USB WiFi adapter, it won't detect it at all. I plugged my MacBook with an ethernet cable to get the drivers, and even used the driver installation disc, and again nothing worked. I am honestly not sure what to do and definitely going a little crazy, haven't found any solution whatsoever online. Hoping someone has dealt with this and has a solution. Thanks so much!

Hey guys, so it turned out that there were two pins that were bent on the flex cable when I took it out! That's what was causing the no wifi. Thanks for all the responses though!

Try a known working wifi card and wifi/camera cable. If it is not this (and it is not a software issue), it will be a logic board issue. Check the components in front of the wifi cable for any which have burnt (inductors, pins on connector, capacitors, etc) and check L3404 on the back of the board, using a schematic and board view, which supplies 5V for wifi to the card, which can commonly burn and stop the voltage passing through.

To see if this a hardware or software issue, Boot the machine from an original system installation disk, or an external device with a lower operating system on it.
