If you're getting disc read error it could be a number of things. Check if there are any objects stuck in the drive (shake the wii or disassemble to look). If not, could be a dirty lens, could be a bad lens. Might be a faulty drive ribbon cable. Need more info.
Need more info on the wifi issue as well. What message is it telling you that it won't connect? Did you accept the user agreements and turn WC24 on?
