We have a Roamio Plus with Lifetime that has had it's Ethernet input burned out, and doesn't show and Wifi Option in the network settings regardless of unplugging etc. The last hope to get program guide info is MoCa then, right? I don't want/don't need to run an entire MoCa network - all I want to do is get Ethernet out of my router 2 feet away from the Tivo - and convert it to cable and put it into a splitter (shared with the cable signal) on the Tivo Input. Can I do this? I emphasize all I need is the Tivo to phone home. Nothing else. No streaming or anything. I'm wondering if this is the right box? (One small possible wrinkle is we use/need a tuning adapter.) Is there any easier way - less expensive/faster/local parts readily available - or if this is all wrong - please help!
