Okay, so the update with mine is that I have all the neccessary settings (DNS, IP, Subnet etc) done, and when I try to connect, it searches for ages (well testing the connection) I think only once that i've done that it's gone to all 3 bars, but i keep getting the error code : 52100.
yet i visited the nintendo wi-fi site and nothing seems to be clear about what I need to do. It says something about my firewall, but i don't know what to do :(
i don't understand as my Wii is perfectly fine on our router.
