Hi, newbie here

I've been trying to get my wii connected through the wireless router. The internet connection test is fine, and it will download updates, but I can't get to the next step and get onto a channel. If I go to network agreements, it throws back a can't connect error (220602) and if I go straight to a channel, it says I need to do the network agreement.

Can anyone tell me what I'm missing here? Are the network agreements online and my connection isn't working properly? If that's the case, any ideas or suggestions much appreciated.
