Hi mate,
First miraclebox I had was showing the same thing, network connection failed using the wizard, ran a network test came back with the same as you posted above.
Swapped wires, reflashed etc, all the usual stuff, turned out to be a faulty ethernet connection on the box.
Maybe this is worth a check, hook up the box as normal, put your line in and switch on your cam, put the box on standby, you should have a green light and orange flashing if you are connecting to the net, even on standby.
I definitely had no lights at the ethernet port on standby, which made sense from what the network test was showing, sent it back and WOS sent me a replacement box and everything worked as expected.
I was probably just a bit unlucky with that box as I haven't really had any issues with plenty of others.
