I have had similar problems with other Macs, my solution was to go into the network configuration and change the speed negotiation from 'Auto' to whatever my router was set for (varied as I changed my hardware often) I found that sometimes the Mac failed to correctly negotiate a connection with the router, try in the first instance setting it to 10mb half duplex, if this works then try 100mb half duplex, then if you are connecting to a switch rather than a basic hub you can try 100mb full duplex.
