Q: G4 Cube Ethernet Problem
I have a G4 Cube with 1 GB of memory, and the Ethernet simply doesn't work. Up until now, it worked perfectly, connecting me to an airport time capsule. All of the sudden, when I turned it on, I am told by Safari that "you are not connected to the internet." I went into system preferences, and tried to "automatically connect to Ethernet," but the auto connect always fails, forcing me to manually connect, in which I do not have the appropriate IP information on hand at the moment. Why would this fail all of the sudden? What can I do to fix it? I have tried restarting the computer multiple times, to no avail. I tried unplugging/replugging the ethernet cable, but nothing changed.
PowerMac, Mac OS X (10.4.11), PowerMac G4 Cube

First try a new ethernet cable. I've had them go bad, usually due to flexing where the cable meets the connector.
Make sure ethernet ports on the computer and the router/modem are clean.
Power-cycle the modem/router. Unplug the power cord for about a minute then reconnect. Wait anther minute or two for the device to reestablish communication with the outside world, then test.
Have you had any electrical storms? There are a number of reports here of lightning strikes during a thunderstorm taking out the ethernet port but leaving other ports undamaged.
