I am afraid that you have not given anywhere near enough information and what you have given is suspect. i.e. Your computer is connected to your router via wireless NOT the Internet.
Soi you need to find out whether router is connected to your internet Service Provider. You can do this by looking at its status lights and going to its Home Page via your PC.
If the above advice does not make sense to you I am afraid that you will need to call someone in.
