The Nintendo 3DS system was unable to connect to the internet.
Did this connection used to work but has suddenly stopped? "Power cycle" your router and modem. To do this, unplug both the modem and the router from the power outlet. Wait a few minutes, and plug the modem back in. Wait a couple of minutes for the modem to initialize, then plug in the router. Try to connect the Wii, Nintendo DS, or Nintendo 3DS online and test for proper response.
To correct this issue you may need to manually configure the Nintendo 3DS internet settings and create an IP Address for your console. For instructions on how to do so please click here.
Should the troubleshooting above not correct your issue please contact Nintendo Consumer
