No matter what I do, my profile remains "offline". I've checked I have internet on, the switch isn't flipped off, and I've set the 3DS there for a good 5 minutes and my profile will not turn online; this renders me unable to register friends :/ What should I do??
Oh, that happens to me sometimes. You might have to get closer to the computer/home phone or something...try scrolling through all of your friends, too, or just let it "load up" for a minute. Eventually it should come back on.
That happens to me at the cafe sometimes because there are a bunch of people around me hogging all the bandwidth. It usually cant be helped unless you can get people to stop using the internet.
That happened to me a couple of weeks ago. It stayed like that for around three days, but eventually it started working normally again without me doing anything.
