Ethernet kexts dont install (Mavericks 10.9.0)

[gamesfnd]

Hey guys, I'm having a big problem here with the ethernet
First: forgive me if already there's another Thread about the same problem but I dont found

Running EVEREST in Windows, returned it of my onboard ethernet card: "nVIDIA MCP61 - LAN Controller (PHY: Realtek RTL8211/8212) PCI"
But in my old OSX (10.6.8) was shows me as: "RTL8029AS"
and I have an offboard ethernet card with realtek chipset too: "RTL8139D"

So... I'm trying to install the ethernet cards, onboard or offboard but nothing works here, I tryed to repair permission using: EFIStudio, Kext Wizard and via terminal
I tryed to install some kexts using Kext Utility, Kext Wizard, Kext Beast and copying
manually with finder, but nothing works and everytime returned me this error dialog


I really dont know what happens, I downloaded kext to RTL8139D, RTL81xx, I tryed to install the kext included in the multibeast for RTL, kext to nforce, and some others but everytime it fails

If someone knows how to fix it I'll be really grateful
