Time Machine fix

Sounds like you need the moddified IONetworkingFamily.kext by ToH. Here it is...

After placing it it /System/Library/Extensions
sudo -s
*password*
rm -rf /System/Library/Extensions.mkext
chmod -R 755 /System/Library/Extensions/IONetworkingFamily.kext
chown -R root:wheel /System/Library/Extensions/IONetworkingFamily.kext
reboot, and keep your fingers crossed
