Nintendo Wifi Acting up

So my DS wifi always works. For the last 2 days, it has not been working. For example, I do the test connection for the 2 connections that I have and both work. Then I go to the Pokemon Center wifi room. I save and go in, it starts to search for a wifi connection and starts connecting with it, after I go in, about 30-40 seconds after I'm inside with full connection I get disconnected and I get an error:
Error code: 84020

When I went to the support website, and searched for this code here's what I got:

Error Code: 84020

We are currently experiencing technical difficulties with the Nintendo Wi-Fi Connection's match-making process. Please try again later.

So what does this mean? how do I fix this? is there a way to fix it?

Beats me. I'll look into it.

EDIT: How is this spam?

Anyways, it seems that it has to do with your router. Try resetting it. Were there any changes recently to it?

On your game, did it say "Communication error you have ben disconnected from Nintendo Wi-Fi Connection" or something different?

Yes thats what it said Communication error.

I'm not sure about this, but there might be a problem with the server that your router's trying to connect to.
