I have a Nintendo 3ds xl and it was always okay. I never had any problems with it actually. But now it doesn't work when this 'wireless' is on. So I can't use street pass or spot pass. When I turn wireless off everything except spot and streetpass work just fine but when I turn it on it still works for about 30 seconds and then there is a text in which isThere was a mistake turn off the system. If that problem stays check out support.nintendo.com.(I translated it from my native language) I checked out the website but I didn't find anything helpful there. I don't know why it doesn't work. Could someone help me? Tell me what causes it could have or how I can fix it maybe, if it's fixable...
