So my Wii U keeps getting error codes whenever I do anything that connects it to the internet. But not all the time. I can browse the eshop, use Miiverse, play a game or whatever, but eventually i'll get an error code. It's different every time and whenever I look them up on Nintendo's site, it says they can't find my specific error code. I tried changing the connection settings and everything, but nothing. My phone and 3DS and PCs have no problems when using the WiFi, only the Wii U. Is there some incompatibility problems here?
