I had resontly sent my 3DS out for repairs and two weeks later it came back. When I turned it on everything seemed fine. The internet and E shop both worked but for some reason my street pass did not. before I sent my 3DS out for repairs I could always use street pass with my friend and we did it every day for about a month. Now that i got it back from repairs though it does not work at all. The green light does not show up and there is no one in my mii plaza. I've tried readjusting the date and time because it said that the year was 2014 but that did't do anything so I tried erasing my friend's mii data and he did the same for me and it still wont work. I've tried everything I can think of and I can't get that street pass to work. please feel free to post a reply. Thanks
My brother and I get streetpass once or twice a day, and our 3ds' are almost always in range, so there is a limit on how many times a day you can get street pass with someone. That might not be the problem though.
