More bad news here, I'm afraid. Similar model, same mfg, would connect wirelessly to router, and to computer, but wouldn't 'connect through'. The manual, freely translated from Taiwanese- or something - is obscure where it needs to be clear, and patronising when dealing with the trivial.
Agree with Keef about the 'easy set-up' option. It ain't... and I just about wore out the reset button. And even reading my copious notes I can't recall exactly what I did to make it work in the end.
And Cat 5 ain't an option, sadly.
