Had a wired setup to both my Series 2 boxes for a few years now and suddenly last night I lost half my network.
After testing the ethernet wires I traced it down to my living room Series 2 DT and as soon as I would plug the ethernet into the tivo my switch would lose connection and knock out my network.
I've got it working on wireless right now albeit slow as piss but it's working. The tivo reports no ethernet cable when i plug it in but the cable is perfect on my tester.
Dead network jack?
