Due to the odd way my college's network is set up, I can't use their network with my Wii (it's a long story, and not exactly relevant to the question). However, my computer can connect perfectly fine, so is there some way I can set up a local network from my computer that I could then connect to with my Wii?
For the record, the computer I'd be using for this is a Macbook Pro, if that affects anything.
You can set up Internet Sharing in the sharing pane in System Preferences.
You will need to have both your Ethernet and AirPort (Wi-Fi) turned on in networking.
Assuming your MacBook is using a wired connection and you want to share using AirPort, choose the following:
Otherwise, you will need to buy Nintendo's Wii LAN Adapter, in which case you can try to connect directly to the network, and should that fail, you can still try Internet Sharing with your computer.
Connecting to the campus Wi-Fi then sharing over ethernet to the LAN Adapter:
Nintendo used to offer a WiFi USB Connector that allowed you to share your PC network connection over WiFi, I don't know if that product is still available but searching ebay for "DS network adapter" returns similar products.
