So one of the lingering issues with my recent build is that my ethernet connect seems to periodically fail after waking from sleep. I'm not sure if it happens every time or just after prolonged sleep. Maybe it's kind of random. I'm using the AppleIntelE1000e.kext 3.3.1.2 (from this site's downloads page) because that one seemed to work best for me. I've tried IntelMausiEthernet.kext but that one didn't work for me, I couldn't select Ethernet from a list of services in the Network control...
