well, i had the same problem with my ds. this is how i solved it... go to manual setup on your wii, then get on you pc (hoping its windows). go to "start" than click on "run". type in *cmd* then type... ipconfig/all ...that is how you find you ip adress stuff like that so on. ok, and the way you see the ip address on your computer, need to be chaged on yur wii. the last number in the ip should be changed to whatever you like. if this is a wep key problem, the wep should be on the bottom of the router.
