Internet connection?

[babe_00001]

Hello, I was wondering if anyone could please help me?

I have a Wireless G+ Router, Wireless G+ Notebook Card, Wireless G+ USB Adapter.

The problem is that the whenever anyone goes onto the laptop, the Internet works and is connected. Now when we go onto the PC however the Internet does not come up and it is disconnected. I have checked everything to do with the connection, and everything seems fine. Now when I went onto the Windows Connection Diagnostic problem thing is comes up with that the Internet connection Belkin is found, but it is disconnected. In my household we really need the Internet on both computers, because three of us are studying and therefore need the Internet.

Please could someone help me! Thanks
