About my PC and internet Connection Problem.?

[894]

I just Installed windows 7 ultimate on my PC and the problem is my internet connection cant connect the icon indicates a yellow Traingle with a Exclamation Point. its Says NETWORK No Internet Access. I check my Network Adapter and my Driver is Installed Properly on my Device Manager. My Internet is OK because it works on my Laptop via Wireless with no problem at all, and even though i connect my laptop thru LAN my Net connections are OK.

You haven't joined the PC to the network, or you are trying to use the same IP address as the laptop.
OR you've forgotten a cable.

Could contact your ISP and make sure all the cables are plugged in too.
