This means you are going to have to enter your details manually. Go to WiFi settings and choose "Manual Settings" or something like that.
The first thing you'll need to do is find out what IP address range you should be using. To do this:
- Click the "Start" button in the lower left-hand corner of your computer.
- Next, you will need to access the command prompt. To do this:
- Windows XP users click "Run." (Windows Vista users click inside the search bar.)
- Type "cmd" into the box and press Enter.
- Type "IPCONFIG/ALL" and press Enter. The IP address, Subnet Mask, Default Gateway, and DNS servers of the PC will be displayed.
The IP address you are going to put to the Nintendo DS must be 10 digits higher than the PC's. (e.g., If your computers IP address is 192.168.1.100 then you will put in your DS 192.168.1.110). The DS and PC must have different IP addresses.
Enter in the exact same values for your Subnet Mask, Default Gateway, Primary DNS and Secondary DNS. They must be the same for your Nintendo DS and for your PC.
And if it still doesn't work, consult Nintendo Customer Service on their Website.
