you can reinstall any of the network drivers from the DVD when you are already booted into your OS X system. with Finder in the menu press [shift]+[command]+[g] and it will bring up the Go To Folder box. Depending on your install disk, the name of your DVD volume will be different, I'm going to use the name "Mac OS X Install DVD" so you can see that spaces are retained in this box... just change the name to fit your install DVD. Now type in: and you'll see the Finder open this up. Now just navigate your way through the folders until you've found them. If you can't find anything matching your network, let me know... but I'd rather not go down the EFI string path right now unless we know we can't fix it any other way.

EDIT: hey man, we are all just trying to help. cut us a little slack. We aren't the one with access to the computer so we can't just know the answers. OS X isn't that cut and dry... it takes time to figure out how to make it work on some systems. Time and Patience.

EDIT #2: according to newegg: http://www.newegg.com/Product/Produc...82E16813185083 you've got a "Broadcom AC131 PHY" built-in LAN. I'll do some more searching but I don't think this is on the disk.

EDIT #3: Last one for the day... (unless you've got more questions)... found this while searching around for the Broadcom AC131 PHY.... The first post I found helpful for you was:

Look through the broadcom section. Should work fine.
