I've had my Roamio Plus and two Minis for a little over a week. While I was out of the house this morning I discovered my iPad app wouldn't connect to the Roamio. I got a message saying the Roamio wasn't connected to the internet. When I got home, I tried one of the Minis. It too said it couldn't connect to the Roamio. I turn on the Roamio and get a welcome screen that says "starting up." It's been stuck on that screen for 10 minutes or more. There's nothing wrong with my internet and TiVo network is all hard wired Ethernet. What's going on?
