First My Home Network: Airport Extreme N, current model, separate discrete g and n networks. G network is set up in WDS mode to extend Airport Express which is connected to a MP via Ethernet. My other Macs are 100% wireless. The problem: The network name of my MP is randomly changed. The original name was simply "MacPro." Then it started to change it's name to MacPro (1), MacPro (2), etc., thinking there was already a computer with the same name in use when it was the same computer all along. The message I get looks like this: I only have this problem on my MP, which again, is connected to an Airport Express via Ethernet. This problem doesn't exist on my machines that have an Airport card installed. Anyone know what is causing this, and more importantly, how to stop it?
