Misc Animal Crossing Wi-Fi Fucked Up

[soliunasm]

It's been about 1 year now and my Animal Crossing still won't connect on my Lite.
I have a Launch Lite, and I played the Animal Crossing online using my Phat. When I started using the Lite, I migrated my settings to the Lite and it wouldn't connect.
So, I deleted the Internet settings and all Wi-Fi data for Animal Crossing(As that one dog told me). Now, whenever it tries connecting, it says it can't find an access point and to call Nintendo etc. etc.
However, all my other games and homebrew connect fine to Wi-Fi.

Anyone know what the problem could be?

If you have a flashcard just backup save and make a new save and see if Wifi works now
If it does work, it is a problem with your settings in your save

Assuming this is the problem(Haven't done it yet), would there be any way to fix the error in the save?
