You need to be a little more clear if this doesn't get you connected.
You have PC1 connected to the router via cable? and PC2 has the wireless card installed and says you are connected to the router that you configured?

Can you browse the internet on PC1?

If they are connected to your router the first thing I would try is disable any firewall that is running (Windows firewall, Norton Security, McAfee Security etc) Then see if you are able to able to browse to a website like Google.
