This error code can
occur for two different reasons:
- You are trying to agree to the User Agreement of the Nintendo DSi or
Nintendo DSi XL, but are receiving error code 51099. This can occur if
the Nintendo DSi or Nintendo DSi XL tries to connect to Nintendo's
servers to download the User Agreement, but there is no existing
Internet connection setup on the system. To connect your Nintendo DSi or
Nintendo DSi XL to the Internet, please click
- You are trying to play a Nintendo DS game online with a Nintendo DSi
or Nintendo DSi XL, but your home Internet is set to WPA security.
Please read the following:
There appears to be a compatibility issue with the security settings
on your router:
Are you using WPA
I am using WEP security
If you are using a Nintendo DSi or Nintendo DSi XL, you will be able
to connect online and use many online features with WPA security.
However, you will not be able to play original
Nintendo DS games
that are Wi-Fi compatible, as they are only
programmed to work with WEP security. In order to play these games
online, you will need to do the following (If you are not receiving this
error when attempting to connect games online, click
error persists while using WEP (or if you are receiving this error with
other Wi-Fi features), follow these steps:
- Change your wireless security to WEP or temporarily disable wireless
security if you wish to connect to the Nintendo Wi-Fi Connection.
- If you are unable to log into your router or do not know how, you
can check our router look-up page (link)
to see if it is listed. If your model number is not listed, check any
similar models from the same manufacturer for default information. If
you are still unable to log into your router, please refer to the router
manufacturer or the company that provided it.
- Make sure your router is not on our list
of incompatible routers. If it is, we recommended using a router
that is compatible or co
nnecting from a hotspot location.
- The wireless security settings are typically found under sections
labeled 'Wireless', 'Basic Wireless' or 'Wireless Security'.
- Change the security mode to WEP, and chose your encryption type.
The 64-bit encryption type typically uses a 10 character key while the
128-bit encryption type uses a 26 character key. Hexadecimal keys
consist of letters A-F and 0-9, whereas ASCII keys have no limitations
and are case sensitive. Be sure to use the key that is listed in 'key
slot 1' and make sure you are not using a 'passphrase'. For specific
information about changing your security type please see your router's
manual or contact the manufacturer.Important Note: it is recommended that any
changes made to the router are performed from a computer that is wired
via Ethernet cable to the router. In addition, any changes made to
wireless security must also be adjusted on other wireless devices in the
home that use the router (e.g. laptops, other game systems, etc). For
instructions on how to change these devices, refer to the user manuals
for these devices or contact the manufacturer.
- Establish a connection in connection files 1-3 on the Nintendo DSi
or Nintendo DSi XL. Make sure you are putting the WEP key into the
Nintendo DSi exactly as it appears on your router page.
- Keep trying, as there may be a temporary network issue. If the
problem persists, or has been consistent over a period of time, move on
to the next step.
- Configure the Nintendo DSi or Nintendo DSi XL manually
Please note: if your router is set to broadcast the network but
the Nintendo DSi or Nintendo DSi XL is not finding the access point then
a manual setup will not resolve the error. There may be another
problem, such as interference, or a basic setting in your router that is
causing compatibility issues. Be sure that your router is set to
'Enable SSID broadcast' or 'Enable Wireless broadcast'. If you prefer
to keep your network name hidden, verify the correct spelling and case
of your router's SSID.
If after trying the steps above you are still receiving this error
code, please call 1-800-255-3700 for further assistance.
