I have been having the hardest time connecting to the internet using Pokemon Y and ACNL ever since I got the games. Connecting to the internet itself is no problem, as the connection test is totally fine and I can even use the internet on my 3DS, but whenever I attempt to connect to the internet, I just can't. An error code sometimes comes up and says "Error code 006-0502, try again later" etc. etc., and other times it'll just say "An error has occurred, try again later."
I've tried everything from signing into the wifi different and sitting closer and unplugging the router and the modem, and I've even gone as far as to try and add my 3DS' IP address into the DMZ of the router's settings, but nothing is working. I also know that it's not just my 3DS that is having issues because my brother's 2DS gets the same error code for Pokemon X and ACNL as well. It's such a bummer that we can't use our games to their full potential for whatever reason, so it'd be pretty gnarly if someone could help.
Oh, and I don't know if this is helpful, but I have a Linksys E4200 router, and the security type is WPA2-PSK (AES). It is password protected.
