Hi. So I've been reading a lot of people having issues with their 3DS XL's having a hard time staying connected to the internet... But mine won't connect at all.
It's a new system that I am trying to set up, it finds my access point and even says in the top left part of the screen that it is connected, but fails on the actual connection test.
My regular 3DS is connected and working on the same access point with the same exact settings that my new 3DS XL is failing at connecting to. Computer, iPhone, iPad, game systems...they are all connecting just fine...it's only my new 3DS XL that can not establish a connection.
And I have rebooted both the router and 3DS XL with no change in the issue. Is this just a defective system? I hope not, since it was a gift. 
Help please.
