This is an interesting one. We have been with TiVo since 2003 and have had a lot of boxes over the years. We started this adventure with our roamio. It had not connected to TiVo for over two weeks. I called TiVo and after being on the phone for 1:20 and troubleshooting everything, they said that the box was bad. The not only wanted $79 for a new box (which I was ok with since it was out of warranty), but also wanted $199 to transfer the lifetime subscription to the new box! I told them that I would be passing on that offer. Now, onto the odd part. After I hung up (and after TiVo closed for the night) I discovered that none of my boxes would connect. I have the Roamio, a premier, a bolt + and two minis. Not one will connect and I am getting C111 and C115 errors on the internet connection. All devices will connect to Netflix and other online media and all can see and stream from each other. I have reset all routers and switches and all are ethernet connections with home runs to the switch. The roamio is the only device that has not connected for two weeks. The others have connected either yesterday or today, but will not connect now. Any thoughts? This one has me stumped.
