First, find out what's causing the problem -- the router or the NIC/computer.

Does your computer have an IP then? Does it say the cable is disconnected? Does the NIC appear "normally" in device manager? Does the router reboot? Does rebooting the router solve the problem? What activity lights do you have on the NIC and router? Have you tried an spare NIC? Can any other computers connect to the web when this one can't? Have you tried a different patch cable? ...

And to help you out, this message you are getting simply means that the computer has lost it's IP address, or it can't see the router or the network cable.
