Windows 7 Wireless Internet Connection

I just bought a new computer with OS Windows 7.
As I was doing the set-up, it asked about the home wireless network and I identified it and entered the internet key.
After the set-up was over, I cannot connect to the wireless network. It says Connected and No Internet access.
It has the Public icon and "Unidentifed network".
I have a "Network error" window that keeps popping up that says "Another computer on this network has the same IP address". I tried one of the solutions on this site to resolve it. I used the Command prompt to release and renew the IP address and seems to not have worked.
How can I get a valid IP address? And how can I make my computer recognize the Home wireless network?
