If you have managed to get your hands on Nintendo's Wii, and go to a university with a wired connection, you're in for some good news. It is possible to share the connection with your Wii by using your Airport card! Don't know how to go about it? Here is the step by step method for Mac OS X (It's pretty damn simple, although I haven't tried it) :

1. You have to be connected to the internet using your Ethernet card

2. Turn on Internet Sharing by going to System Preferences, clicking the Internet Tab, Share your connection from “Built-in Ethernet” to Computers using “Airport”.

3. Click “Airport Options” and enter in a network name. Keep channel on Automatic.

4. If you want to make sure nobody else can leech off your network, enable WEP encryption, set the key length to 128-bit, and enter in a 13 digit code. Click OK.

5. Hit Start to turn internet sharing on, and close out of the system preferences.

6. Open Terminal.app (Open your hard drive, then click Applications, then click Utilities. It should be there.)

7. Type: ifconfig en1

8. Look for: inet xxx.xxx.xxx.xxx netmask

9. Write down the IP address (the x’s) from the first inet. For me, that was 10.0.2.1

10. Type: dig

11. Near the bottom it should say SERVER: xxx.xxx.xxx.xxx. Write this down, this number will be used for your Wii’s DNS Server.

12. Now configure your Wii’s internet settings.

13. Go to Wii Settings, and then Internet. Select a connection, and select wireless. Click Manual setup.
14. Your SSID is whatever you named your network.

15. If you used a WEP key, select WEP for your type of security and type in whatever 13 digit passcode you made up.

16. Select NO for Auto-obtain IP address, then go to advanced settings. For your IP address, take whatever IP address you initially wrote down, and increase the last number by 1. For example, mine was 10.0.2.1, so I made by Wii’s IP address 10.0.2.5
17. Your subnet mask is 255.255.255.0

18. Your Default Router is the first IP address you wrote down, but this time unchanged. Mine was 10.0.2.1

19. Hit confirm.

20. Click NO for Auto obtain DNS, and then go to advanced settings.

21. Your Primary DNS is the DNS Server you got from your earlier dig output. Leave the secondary DNS as 000.000.000.000

22. Press confirm.

23. Don’t use a proxy server.

24. Keep your MTU value as 0.

25. Save and test it! If it works, hooray! If not, make sure you entered everything in correctly!

These steps will probably work with your Nintendo DS as well, that is, if you get to work at all. But I'm sure you wont have any problems with this mini guide of just 25 steps of technical instructions!
