We have Xfinity/Comcast TV and internet through one of their Gateway modems. We have a Tivo Roamio Plus, with 2 Tivo Minis and a Tivo Mini Vox connected through moCa. We started to have digital tiling so an Xfinity service rep. came and replaced the old Gateway we had for a Technicolor brand Xfinity X1 Gateway. He enabled moCa and said everything should be working fine, but I didn't check the Tivo minis while he was here. You guessed it, they won't log on. I've talked to Tivo reps twice, and had another Xfinity service rep. come out and no one can figure out why the minis won't connect to the new gateway. Going to network settings, moCa, set up as client, no encryption all works, but when it asks to select a DHCP server it won't connect to the internet. On the Tivo mini vox I get a C7 message saying it can't find the router. On the two older minis it says C12, check that the firewall is not blocking ports (it's not). Anyone have any suggestions! Tired of going back and forth between these two companies!!
