I've set up internet on my Wii U but it isn't working?

Solution 1:

These are some of the steps I took to troubleshoot my own Wii U, from very early on I noticed the WiFi-connection being lackluster on the Wii U. It probably doesn't help that the Wii U is continuously streaming an HD-feed to the GamePad at the same time.

Establishing a connection

Nintendo supplied a simple guide on how to connect to the internet or follow the steps laid out in DarkWoffle's answer.

• The Wii U can have problems keeping a connection when there's something touching (or lying on top of) the console. Even with my router within reaching distance, it just wouldn't connect.
• You can test the internet connection without a TV! Accessing the Settings only requires the screen of the GamePad. If you're having trouble connecting, find a good spot closer to the router/modem and try connecting again. This way you know if distance is the problem. (I also do this if I want to speed up my download of a 17GB-game).
• For any serious online gamer, or anybody having trouble with the internet connection, I recommend the Wii LAN Adapter. Ethernet is way more reliable than WiFi.

There are more specific problems known with the Wii U that I'm not going to explain here, those require a more in-depth guide. In any case, you can contact Nintendo for additional support.
