Earlier I answered this...

A wireles hub/router is usually permanently connected to the internet - that's what its job is. For your computer to see the internet you need to establish a Network Connection to the the router.
Use Control Panel / Network Connections
You should see a wireless icon - if you don't then you may need to install the driver for your machine's wireless device.
Right click on the wireless icon and select View Available Wireless Networks - you may see several - I see five - connect to your own router - usually the strongest signal.
If this does not work then contact your ISP Good luck...
