I had to set mine up by connecting it to my laptop.
My problem with the adaptor was I couldn't find printed anywhere in the instructions the IP address for the browser setup menu? I am missing something here
Eventually found it by watching a YouTube video, is was: 192.168.16.254, mine was the same, I don't know if they all are?
Anyway so far I have had it working on my laptop, Xbox and Xbox 360
I'm wondering if anyone has managed to set one up with the WPS button on their router and the one on the adaptor, I presume that's what it is anyway

This would mean you wouldn't need a computer at all to set up with a console.
