Connection problems: WPA2 and University Wi-Fi

[Circa]

I live in a dormitory at a university, and have access to Wi-Fi. I have been trying to connect my Wii to it, but have so far been unsuccessful. The university's Wi-Fi is WPA2, and requires a username as well as a password when signing on, however, I have not found a way to enter a username when connecting on the Wii.

Any advice on how I should approach this problem?

Also, I have already registered the MAC address with the university, so that should not be an issue. As a note, I am receiving error code: 51030


Any help would be greatly appreciated, thanks!
