You can try this as...
it sounds to me you have not enabled your laptop to connect to the internet through your wireless network.
Right click on the internet icon in the quick launch (lower right) > if you are asked for a password, enter it > then you should be online. You may have to reboot, if you do, reboot your router too. Wait at least 1 minute when you turn off your router before turning it on again. Also it is a good idea to unplug the router and wait.
