Fork of Mieze’s Realtek RTL8111 Network Driver by RehabMan
How to Install:
First you must remove any other Realtek driver you may have installed.
Common ones are: RealtekRTL81xx.kext RealtekRTL8000SL.kext AppleRTL8169Ethernet.kext
It is possible that these kexts are installed under directly in /System/Library/Extensions or under /S/L/E/IONetworkingFamily.kext/Contents/PlugIns, so be sure to check both locations.
Next, install the kext using Kext Wizard or your favorite kext installer.
Special note for Snow Leopard users: There is a conflict between the RTL8169 driver that is part of Snow Leopard and this driver. The RTL8169 driver, during its probe method, puts the hardware into a bad state where it cannot be detected properly by this driver. As a result, you must remove it:
sudo rm -rf /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns/AppleRTL8169Ethernet.kext
Note: The current v2 build supports only Mountain Lion 10.8 or newer.
