Signed up today on this site. My xbox ones internet connection all of a sudden stopped working after 2 weeks use. It said I had no toredo IP and to open port 3544. I looked up every possible solution about forwarding ports and what not. After a good 3 hours with my mate who is a programmer (or something along those lines) he couldn't fix it. Then after he left I read somewhere that if you restore your xbox one to factory default and change location from Nz to Australia it can work. I gave this a go and to my surprise this has worked for me. I'm still amazed. I'm not sure how long his will work for but I will respond to this thread if it does crap out again
