Update: voodooHDA from the link above is working except for native volume control. Still no luck with the wg111v3. (now always booting 32bit mode). Either manually placing the kext in or using the installer pig from netgear both give me a popup error saying the kext was not installed properly. The error stops popping up if I manually place in and then repair permissions, but still not working. Haven looked further into LAN yet.

Thanks for your help so far I feel like I'm getting somewhere!
