Are you sure that the network you are connected to has internet access, or that you are connected to it properly? Try connecting to the wireless router. You can do this by clicking the connection icon in the taskbar, right-clicking the network that you are connected to, clicking "status", clicking "details", and putting the number under "IPv4 Default Gateway" into your browser URL bar. If you see the router config screen, or get a windows asking for a username and password, then you are connected to the router. While you have Status-->Details open, It's a good idea to check the rest of the stats. If you can connect to the router using that number, and you still cannot visit any web pages, then list the other stats here so we can see them. It's ok if it says "no internet access" under "ipv6 connectivity", that is ok as long as your router does not support ipv6.
