Advertisements I upgraded my Xfinity modem (that I was paying $13/month) and purchased a Netgear CM1150V. The good news is my data speed is 3x faster. The bad news is I can't connect to Tivo. I have a primary Tivo with 2 minis. I have MOCA adapters. Everything was fine w/ old modem but I've tried rebooting, unplugging and everything else.
