Yup, when I built his machine I made a custom DSDT however that has nothing (that I can figure) to do with this problem. The *only* thing I did was to replace his com.apple.boot.plist with mine in an attempt to get his machine into 32bit mode instead of 64bit mode, and rebooted his machine after doing so. It didn't work BTW. No other changes were made. Oh, and yes, internet does work as his VOIP is still working fine.

I am taking my machine over to his place tomorrow to see if I can diagnose something that way however if both are showing that the network is there yet only one of them is working I will still be at a loss.....
