gemini1364, when you say "brand new," do you mean fresh out of the box? Or did it have a configuration before? If the error light is blinking that can actually be a good thing, meaning it is stuck in the booter and can be recovered. If the error light is ON solid that is when things are definitely NOT good; as in, a hardware failure is possible.
There is a tool in DirectSOFT6 called IPConfig. You can double-click on it in DSLaunch in the Utilities. This utility allows you to recover a Host Ethernet device on a network when it is not visible in NetEdit by using only its MAC (Ethernet) Address that is printed on its label. Use the <Help> button to understand how to use it.
Let us know.
