    After upgrading to Mountain Lion I have noticed sometimes when I wake the iMac from sleep the ethernet adapter says not connected, it happens 1 or 2 times a week. A reboot seems to fix the problem. Never happened with Lion.

    Same here. Issue started with mountain lion.

    Seems to be a driver issue.

    Now appeared on my iMac....SMC deleting connection, no effect. Only a re-boot fixes it. Definitely an OSX issue.
