The codes should be existing wep internet key for security settings. From settings screen select wireless settings and it should be default to detect. Allow the set up to direct to code screen, then enter key. If information unknown call ISP.
The DSi can use any Security settings a WII can use

the same thing happened to me but what i did was that i updated it in the settings menu
This is a problem with the security settings on your wireless connection. To do what you were doing when the error code appeared, change your wireless network security type to WEP, or disable security (not recommended).
yes just push the format botton on the dsi settings
The same problem happened to me too. All you have to do is get a parent to look at your connection settings. I also had a Belkin Router, but i changed it for something else. It might be the router.
You get it by going on the dsi shop. and on the settings you can cet wi-fi connection.
go to settings
Menu<Settings<Phone Settings< Security<Edit Codes<Phone Only. The phone only locks on powerup, though.
you can get the dsi cheat codes at gamestop
You can use Wifi on a DSI, if it doesn't work with you then it's probably because you have WPA connection security settings. WPA connection will allow you to surf the internet and go on the DSI Shop etc., but will not allow you to play games over Nintendo Wifi Connection. To do this, you will have to change your settings to WEP so that you can play on Wifi on your DSI. However, WEP is not as safe to use an internet connection as WPA, so be careful. Hope I Helped...

you go to system settings, and go to internet, or, you can download the Nintendo dsi browser from the dsi store for free.
