I would love to just delete my wifi settings, but I'm not sure how to set an internal network for the Wii U, otherwise, I would probably take that route. If it's not too much trouble, could you point me to a tutorial on how to set this private network?
You can just go into settings and delete them, then you know your system won't connect to anything while powered down.
As for an internal network, there isn't really any trick to it as it is just what it sounds like. I keep a second wifi access point going that has some stuff on it I don't want to connect to the internet (Playstation TV, Wii U, a Raspberry Pi, ect.)
