Error Codes: 61020-61070

"Error messages within this range are typically caused by temporary network outages with the Nintendo WiFi Connection. If there is a problem with the network, Nintendo's technicians will do their best to get the service back up as soon as possible."

If you are connecting to the Nintendo WiFi Connection for the first time, or the problem has not resolved itself after a few hours, there could be an incompatibility with your wireless home network. You may want to try the following:

Ensure your router has the latest firmware installed. Visit your router manufacturer’s website and look for any updated firmware that may be available (these are typically found under “downloads” or by searching for your particular model number). Contact your router manufacturer for additional assistance.

If your router or modem has a built-in firewall, you may want to try and lower the security settings, as they could be interfering with a successful connection. How to do this will vary brand and model, so consult the manual or the manufacturer of your router or modem for assistance.

If after trying the above steps you are still unable to successfully login or connect to the Nintendo WiFi Connection, it is possible that your wireless home network is not compatible with the Nintendo DS or the Nintendo WiFi Connection. Nintendo suggests purchasing a compatible router, (click here for a list of routers Nintendo tested and ranked), or the Nintendo WiFi USB Connector. (Please note that if your modem is blocking the connection, the USB Connector will not work).

Error Code: 80430

"This error generally occurs when two or more Nintendo DS systems are unable to establish a direct connection, usually due to high wireless traffic or firewall settings on your router or your friend's router."

"I've never been able to connect. I get this code every single time I try to connect."

Netgear Routers
Sometimes older Netgear routers have difficulty in establishing the type of player to player connections (i.e., a direct connection) the Nintendo DS requires for online play.

Firewall Info
Your router's firewall may be blocking some necessary ports. You may consider adjusting your router's Port Forwarding settings. Each router is unique, so consult the owner's manual for your router or contact the manufacturer for specific information on working with your router's ports. For your information:

You will need to manually assign a new IP address to your Nintendo DS.
If your router prompts for a device or profile name, you can enter anything you like (such as Nintendo DS, etc.).
The starting port to open is 1, the ending port to open is 65535 (or as high as your router will allow).
Protocols will need to be set to UDP only.
Set the IP address for the ports to forward to the same as the DS's static IP.

Noisy/Busy Area
Ensure that your router is set to either channel 1,6, or 11.

"I get this error code every once and awhile. Some days are better than others."

Noisy/Busy Area
Ensure that your router is set to either channel 1,6, or 11.

Something in your setup
Turn off other wireless devices while playing, such as cordless phones, other handheld game systems, or wireless computers.

Friend's Settings
If you recieve this error only when playing with a particular friend, then it is likely a problem with the friend's firewall settings on their connection. If possible, recommend to your friend that they visit the technical support area of www.nintendowifi.com for possible solutions.

"Until recently, I've been able to connect to the Nintendo WiFi Connection just fine. Now I'm getting this error code."

"The Access Point you are attempting to connect to is not connected to the internet, or a firewall is blocking traffic necessary for connecting to the Nintendo WiFi Connection. What to do will depend on where you are trying to connect from."

What to do:
If you have multiple connection files saved to your Nintendo DS, the error message you received can help determine which connection file may be experiencing a problem:

Errors ending in 0 = Connection File 1
Errors ending in 1 = Connection File 2
Errors ending in 2 = Connection File 3
Errors ending in 3 = Nintendo WiFi USB Connector

Verify that your router is connected to the internet when attempting to connect to the Nintendo WiFi Connection. If you are not able to access the internet on your computer, then there is a problem with your internet connection. Contact your Internet Service Provider (ISP) for more information. AOL broadband users may experience difficulties when attempting to connect to the Nintendo WiFi Connection. Contact AOL for assistance.

If this error occurs regularly, while you are playing at home, it is likely a connection problem related to your firewall settings. For more information on firewalls and the Nintendo WiFi Connection, click here.

"The Nintendo WiFi USB Connector is unable to connect to the Nintendo WiFi Connection."

Are you using an anti-virus or firewall security program (such as Norton, Symantec, Zone Alarm, etc.)? If so, read the following.
Check for an option to "add" the registration tool to it's list of allowed applications. Test the connection after adding the registration tool.
Disable the personal firewall portion of the software. Test the connection.
Disable the entire security program, and test the connection.

Does your Internet Service Provider (ISP) require you to sign in each time you wish to connect to the internet?
Some popular ISPs require a login each time you wish to connect, instead of an "always on" connection. Because the Nintendo WiFi USB Connector does not have a login tool to work these types of connections, the Nintendo WiFi USB Connector may be incompatible with your home network. You may want to contact your ISP, or purchase a compatible router instead of using the Nintendo WiFi USB Connector. Click here for help finding a compatible router.

Most routers have built-in firewalls. Some firewall settings could interfere with the Nintendo WiFi USB Connector. Try logging into the router using it's default IP address (consult the router's manual for assistance) and lowering the security or disabling the firewall altogether.

If the above information does not work, it is possible that the Nintendo WiFi USB Connector is incompatible with your home network. You may want to consider purchasing a compatible router. Click here to view Nintendo's list of router rankings.
