Broadcom 5752

I have the same exact card as someone (A.A.) who posted this .kext on the InsanelyMac forums. I don't know what the heck I am doing wrong but this is getting very frustrating since it is the last piece of my PC to Mac puzzle.

I've tried many different ways to install this .kext and I just can't get my Ethernet card to be recognized.

What am I doing wrong?

I've saved the .kext to a PC. I saved it to a thumb drive and copied it over to my Mac OS Desktop. File called "AppleBCM5751Ethernet.kext"

If I "Show Package Contents" on AppleBCM* I see 2 files. A folder called "_MACOSX" and another .kext file named the same (AppleBCM*). Within that "_MACOSX" folder is another .kext file (same name - AppleBCM*).

Should I be installing the entire .kext I saved onto my desktop? It just seems weird that there is a _MACOSX file and a normal .kext in the original package.

Here is the installation I found and tried using:

1) I made sure there were no other instances of AppleBCM5751Ethernet.kext

2) Commands:

sudo -s
<root password>
cp -r -v ~Desktop/AppleB* /S*/L*/E*/IONet*/C*/Plug*/
rm -v /S*/L*/E*.mke*
diskutil repairpermissions /
reboot

You see anything I may be missing?

Here is the link to the .kext file I'm using:
