I tried the Apple Support forums (link) but got nothing. I've searched and searched but can't seem to find a similar problem or a solution.
My TC is connected directly via ethernet. The orange light just keeps blinking. I connect to the Internet via my wi-fi router and just use the TC to make backups these days.
Update Edit: So I attempted a factory reset and all that seems to have done is allow me to lose all my previous backups and accomplish nothing else. When I select "Ethernet" in Airport Utility it shows my TC (even though the status says Ethernet unplugged now) but in my Time Machine preferences the TC doesn't show up at all.
It appears as though Airport Utility sees the disk.
