My PC doesn't want to connect to the internet

Hi, so my PC has been dead for a couple of months, and only yesterday was fixed. (Problem with the hard disk, had to re-install windows, etc, etc...)

Anyhow. I've finally gotten most of the stuff I want back onto it. However, when I tried to connect to the internet, nothing happened..

I plugged in the ethernet cable, my modem says everything is fine. But when I try to connect, it says that I'm not...

I've tried setting up a new connection, no help there, since it just goes ahead and tells me that "Your broadband connection should already be configured and ready to use"...

So I looked in my network connections, and it says that the 1394 Connection is connected...

Now, I'm no professional with computers or networks or whatever, so if there's anything I'm missing, could someone help?

Note: I'm connecting through a Bigpond D-Link modem, straight to the internet.. And it's not the cable, modem, or ISP, since I'm connecting fine with all of those with this laptop....
