Nintendo DSi wont connect to Shared Internet.

Question

Hi, I have my Mac Mini set to shared Internet so I can keep using the WPA for my wii, ps3 & psp, but use my computers airport card for WEP. My psp can connect fine, but my DSi will lose the connection during the test, any Ideas?

Answer 1

I found this on the internet because I have been having the same problem with my DS. Just follow these steps and it should work.
First you need to go to the system preferences panel. Click the sharing folder icon.
Under sharing, go to the internet tab. Go to the drop down menu and click "built-in Ethernet".
Below that there are check boxes, click "airport". Then click ariport options.
Put in a name, a short one is ideal, and then a password if you want. (only numbers) Click ok.
Now go to the firewall tab. If your brave enough, you can just turn off the firewall. Or...
Click "new". The port name is "other", make the description something short like, "my wii".
THIS IS IMPORTANT.
Under the "TCP Port Number(s)" field type (with the commas): 28910, 29900, 29901, 29920, 80, 443
Leave the UDP blank. Click ok.
Make sure that box is checked, go back to internet and click "start".
Your airport icon on top of the screen should be showing an upward arrow.
NOW...for the Wii setup. Fun isn't it?
Go to your wii setup, then internet tab. Click an empty network or erase one. Now click manual.
Enter the name of your network, what you labeled earlier. If you forgot, click the airport icon, it should show you what signal is being sent out.
Now click the arrow and enter your WEP key. The 10 digit numerical password you made. (unless you didn't)
Click the arrow again and where it says auto-obtain IP settings, click no. Enter these; (there will be a lot more zero's auto added when you click ok. leave them)
IP: 10.0.2.11
Subnet: 255.255.255.0
Default Router: 10.0.2.1
Manual DNS settings:
Go to the next screen and again NO auto-obtain DNS.
Primary DNS: 10.0.2.1
Secondary: 10.0.2.11
Leave all the other windows, click save. It should connect.
To stop you Mac from sending the signal, click the airport icon, then internet sharing. You can now click "stop". You airport will go back to normal use. To re-connect to the wii, just go back to the internet sharing and click start. It'll keep all the previous settings.
Good luck and good night.
(As a bonus, do the same wii setup for the DS to work, if you have one)
