Check out support.nintendo.com. It has a lot of supports. And check if your college use proxy. If they do, type it in on your wii. And maybe this is a problem with IP and DNS. Go to your wii. Then click on wii settings. Then go right, then internet. Now, you could check out IP and DNS on your computer. If you are using Windows, go to start, then run. Then type cmd. When the creepy window pops out, type ipconfig/all. This should do it. If you are a mac user, click on system preferences, then the network (the small globe). That will do. Again, check out the website on this post. You can get more information there. I am only copying this for you. Going to the website will be more easier.
