You will have your regular netwrok connections, and then another one ( go to your network connections pannel and see you will have a new connection probably named "Connection #".......#being whatever is next in your sequence, it was 6 for me). The Wii does not have 802.1x built in. So i had to take the extra step of turning off windows firewall and the protocol....
Right click the connection your Wii will be using, goto properties and take 3 steps:
1:General Tab > deselect any protocol other than Microsoft networks, File sharing, QoS packet, and TCP/IP
2: Authentication tab > deselect IEEE 802.1x authentication for this network
3: Advanced tab> Settings > select off for Windows firewall (just for that connection)
Now, I was able to connect. This can apply for other protcols also. I'm pretty sure the Wii sin't going to have most of the standards in authentication.
Nintendos tech support is actualy able to help you with this problem now. I called them and was on the phone for an hour trying to get it to work. After I hung up with them it finaly hit me what was wrong. They called back 3 days later and asked me if I still needed assistance (pretty nice of them, I think). After I told them I got it working they asked me what I did. Once i explaned the process they told me that they were going to enter that into their system, as they have alot of college kids calling for connection support.....Go me!
