I have the same problem here at home -- the empeg just plain has a bug of some kind in it's ethernet init code. Never resolved. So I use the ;@WORK/;@HOME thing to toggle between DHCP enabled and DHCP not enabled, for when I use it in a demo or something where it works.

Works fine, btw, when plugged into a 10mb/s hub; but not when on a 10/100 hub or a 10/100 switch. Just plain buggy.

Cheers
