Here is Phystars latest R1000 driver modified for D-Link DGE-528T, works just fine.

Unpack to desktop and install by:
sudo -s
cd /System/Library/Extensions/IONetworkingFamily.kext/Contents/PlugIns
mv AppleRTL8169Ethernet.kext ~/Desktop/AppleRTL8169Ethernet.kext
cd /System/Library/Extensions
cp -R ~/Desktop/RealtekR1000.kext /System/Library/Extensions
chmod -R 755 RealtekR1000.kext
chown -R root:wheel RealtekR1000.kext
kextload RealtekR1000.kext
And is should now be working!
