When I go to my wii internet connection my router is locked. How do I unlock my router from my computer?

First you have to look for a code that is were where on the router. It will be something like a WEp Essid or mac code. If you find that, then go into your Wii connection setting. GO to the last selection and go put the code into the Wii. Routers just want the code so they know your the one using it and not someone trying to get free internet.
