So I bought a 3DS a couple of months ago and could connect it to the internet without any problem, whenever I've searched for an internet access point it would easily find it, I had it configured so that it would connect to the internet in my home but two days ago it just stopped recognizing the wireless connection and now it won't find anything when I look for "access points", previously when I wanted to configure some connection it would show all the possible connections, but now it won't find anything, even when i'm sitting half a meter from my router, I don't know what to do, I thought the 3DS capability to find an internet connection no longer worked, but earlier today it managed to find around 5 possible conections, including mine, I managed keep it connected to my internet for about half an hour and then back to nothing, and just as before, when looking for possible connections it show no results and it just says "Could not find any access points. Change your location or confirm that the acces point is active, and try again." 

I really don't know what to do, I tried everything, messing around with the router settings and that stuff, I'm no expert on this things so I'd like to know what you guys think or if you have any recommendations for me. Thanks a lot duders.
