Hi. My name is David. Just yesterday, I was able to open the browser on my Nintendo 3DS XL just fine. I went to GameStop later that day to get the Shiny Dialga for my Pokémon Black Version 2 and my little sister's Pokémon White Version 2 (on two different 3DS XLs), but when I came back, I noticed I couldn't connect to the eShop, and my sister couldn't connect to the internet either. The reason I think it was the Pokémon games that messed our 3DSs up is because I've seen multiple people have the same problem, except it only occured when they sent their Pokémon to the Dream World. I've tried changing my settings, but to no avail.
I keep being greeted with Mr. Error Code: 003-1102. I haven't been able to find a solution yet. Anyone capable of helping me?
