So I've been having a problem with my Wii U, and specifically Splatoon, whereas connecting to the internet and playing online is concerned.
Ever since I got back to college after my winter break, I haven't been able to play Splatoon online. I can get to the list of modes to play, and get to the "Searching for a battle..." screen, but I always get an error at that point, followed by an eventual "Connection has been lost" screen, sending me back to the plaza.
But that's not even the weirdest part. A few days ago on my Wii U, I was able to get to the online part of Super Mario Maker, play levels, and access the eShop. This stopped when I tried again a couple days ago. I can also play online and do all online features on my Xbox 360. At this point, I'm not really sure what to do or why this is happening solely with Splatoon and the Wii U.
If anyone could help, that would be greatly appreciated. Thank you in advance!
