Is it actually obvious that you have Wifi hardware on your PC's motherboard? Your Dell Inspiron 660 does not come with either integrated or an added wireless card. Did you specifically install a wireless card? If not, it cannot access lest even be aware of any wireless network because it lacks the hardware.
I'd imagine your wireless router has a place to plug in
a LAN cord. If you get such a cord, plug it in to the back of your DELL and then in to the router, UberStudent should detect and connect to the network automatically (it should be doing this with any wireless network, too, but one step at a time). Otherwise, if you are SURE your PC has a wireless card that you or someone else explicitly installed in to it, let me know.
