Please help! My new iMac is conflicting with another computer on my home network. The network uses an SMC Barricade router with wireless. Connected to that via ethernet is a G4 Quicksilver. My wife has an iBook connected via wireless. I just got a spiffy new 24' iMac. I can connect that to the network via ethernet without problem, as long as the G4 is turned off. However, if the G4 is on, the iMac's connection fails. In the Network Status preference pane the ethernet status icon will blink rapidly from green to red and a message will appear saying that the ethernet cable is not connected. If I turn off the ethernet on the iMac and switch on the built in Airport, both computers can access the network without conflict. Similarly, if I turn off the ethernet on the G4, the ethernet connection on the iMac works fine. Obviously there's an ethernet conflict of some sort, but my diagnostic skills can take me no further. Any advice or suggestions will be much appreciated.
