"Check the firewall settings on your router. It is possible that your router's firewall may be preventing your 3DS from getting online. You may need to disable it to resolve your connection issue. If you are comfortable doing so, disable the firewall and test the connection. If you have any questions on how disabling your firewall may affect your network, we recommend contacting your router manufacturer for more information.
*Power cycle your router. This can be done by unplugging the power cable from the router for one minute, then plugging it back in. Once the router restarts, attempt to download the update once more.
· Setup a manual connection. Directions can be found at the following website under "Help with Wireless Routers:"

*Adjust the Port Forwarding settings on your router. Each router is unique, so consult your owner's manual or contact the manufacturer for specific information on adjusting your router's ports. Your 3DS will need a static IP address before Port Forwarding will work. To do this, set up a manual connection on the 3DS.
- If you are prompted to enter a profile name when setting up Port Forwarding, you can enter anything you like (such as 3DS).
- The starting port to open is 1, the ending port to open is 65535 (or as high as the router will allow, sometimes 65534).
- Protocols will need to be set to UDP only.
- Set the IP address for the ports to forward to the same static IP address as the 3DS.
*Place the IP address of the 3DS in the DMZ of the router. Please consult your router's user manual for more information on where to locate this setting.
*Verify your router is using the latest firmware. You can check your router manufacturer’s website to download any updates for your router.
