Do other devices in your home have internet? Do you have static or dynamic IP?
FYI "Connected" means you have a connection from the computer/device to your router, does not mean your router is connected to the internet.
So many people beleive WiFi and internet mean the same thing, they dont. WiFi is just a way to wirelessly connect to your router, an internet connection means your router can connect to an ISP that then gives them a connection to the internet.
