I get a clear signal and the computer shows that it is connected to the network, but the pages don't load. The message at the bottom of the window reads: "waiting for www.google.com..." -or- whatever page I am trying to get. Also, with this WiFi device, will I be able to stream live TV? Or should I purchase a newer WiFi USB device?
It looks like you're connecting fine to your WiFi router. So, if possible, try to access your router configuration page (you will find details on how to do this in your router handbook) and check if you have in place restrictions like MAC filtering or some firewall settings for your connection.
