A while ago I connected my 3DS to the internet at my father's house and looked like it connected fine. When I went to check my friends list, it said that I was offline. I waited a couple more minutes but it didn't change. I was able to use the internet, Miiverse , and the e-shop, but I wasn't able to do any multiplayer features on any of my games. I'm wondering if it's the system that's causing the problem or that it's just the internet only allowing certain things I can do.
Just to see if it happened to anything else, I checked my other electronics and found out that it was happening to those too. I'm guessing that the internet is restricting certain things I can do.
