Just got back from vacation, so have not used it in a couple of weeks, but my Belkin Thunderbolt dock ethernet is not initializing. Tried rebooting my Macbook Pro (late 2013), tried powering off and on the dock, but no joy. The yellow light is flashing on the dock, and my hub light is on and flashing as well, just not getting an IP address on my computer. Anyone have any ideas? TIA!
