not all problems have to do with the system check the disc and see if something is wrong with the disc or check the wii itself not just the system but the wii's parts and make sure the disc and the wii are all functioning correctly and make sure that no part of the wii or disc is scratched up or damaged.
The password or key for your wireless router that was entered is incorrect.
Make sure the password or key is entered into the Wii exactly as it appears in your router's settings. Keep in mind that security keys are case sensitive. A simple typo may be causing the problem.
