Go to the System Preferences and select the Network Pane.
On the Built-In ethernet, choose DHCP as the connection type. From this point on, everything should be automatic. Close the Pane.
You may have to reboot the machine before it gets a good IP address.
After reboot, go back to the network pane/built-in ethernet and make a not of the IP address.
If it starts 192.168. you should be fine. If it starts 169. you are not fine.
On the Router, make sure that everything is set correctly there and that you are not preventing any machine from accessing the Internet through the Router Firewall, if it has one.
If the problem still exists, consider disconnecting the Router from the Modem and plugging the Mac directly into the modem. If you access the Internet that way, then the problem is with the router setup

I just bought a 15" powerbook g4 with the superdrive/1.67 gH and stuff and I can't connect to the internet. This is the first apple my house has ever owned and the internet has worked fine with our few PCs. The house is networked through a rotor which is plugged into wireless/cable connection. Forgive me, I'm not great with computers, so hal of that termonology could very well have been way wrong. ANYWAY, I figured that the powerbook would recognize the internet connection as soon as I plugged in the ethernet cable, but it isn't. It's recognized that a cable is plugged in, but it won't connect to the internet. Can anyone help? I tried manually setting up a connectiong (typing in the IP address, DNS servers, gateway addresses, etc) but it hasn't worked. Has anyone else had this problem and can anyone think of a way to fix it? Thanks
