I set up my NNID on my 3DS when Miiverse was brought to that, then I got a Wii U. I'm still at the point of setting up the Wii U where I can choose between creating a new NNID for the Wii U or using an existing one. Of course I'd choose the latter, but... when I enter all the info, it says it can't connect to the internet, likely because the automatic password is incorrect (it is). It says I can go to the internet settings on the Wii U to fiddle with that, but I can't go the menu yet because I'm still setting up. It takes me to the two choices after that. Do I just choose the first option that's explicitly recommended for new users and hope it'll work out, or is there a way to remedy this?
As for why it can't connect to the internet when that step came before NNID: our internet router is password protected, one of those complicated passwords. I tried it from memory first, thinking I'd go fetch it later if I don't remember it. My input turned out to be wrong, but I couldn't find anywhere where I could try a second time after. Pressing back actually took me to the next step; I guess it assumed I was okay with the connection. I know it's a silly reason for all this, and I'd hate to have it lead to having two seperate accounts for something so simple.
