Wii U online features not loading

I have had no issues with any of the features on my Wii U until 2 days ago. I tried to load netflix and it said there was an error and it could not load the page. THe same thing happened with Miiverse. I assumed something was just going on at that time and I would try again later, however last night neither would load and I kept getting error messages. Everytime I searched the error codes I was getting (which were different every time) the support site said they could not find what the code stood for.

I know that it is not the Wii U not connecting to internet because I ran a connection test that was successful. Also, I can go into the browser and surf the web with no issues. But any features of Wii U that go online will not work, primarily the Miiverse and Netflix. Has anyone else run into this issue? I am thinking about calling Nintendo tonight about it.

I had the same problem, I could browse the internet and connection test was succesful, but any actual online software such as e-shop or online game features wouldn't load and I would get an array of different error codes.

However I moved my console into another room closer to the router, and they worked. So I concluded my connection wasn't strong enough in the original room to use the more intensive online services. I have now set up with a wired connection and there are no problems.

However you mentioned you had been able to use services like e-shop or netflix up until two days ago (without moving your console?) so that is slightly different to my situation.

That is exactly my problem, except for the fact that it had been working just fine. Also, I have tried setting a new connection and the new connection could not connect to internet so I went back to the first connection I had already set up. Maybe tonight I will delete the original connection and try it that way.
