Router Detection Issues

[eldorado865]

I have a fairly new HP computer. It came with Vista and I received an free Windows 64 bit upgrade. I have tried to install a Lynksys and a Netgear router with no luck. My latest is the Netgear. I have done everything correctly. The modem lights up and the router lights up but no internet access. The only message I get is "Local area connection doesn't have a valid IP configuration. I have no idea what to do. I always thought it was a configuration problem but I just don't know how to change anything.
When I go to my Network and Sharing Center with just my modem connected it says I am connected to Network 2.
I don't understand that either, isn't it supposed to just say Network? As far as I know I don't have two networks going.
My network adapter is Nvidia nForce 10/100 Mbps Ethernet. It is the only listing in Network Adapters in Control Panel. Below is my Network Connection Details with just the modem connected.
