If you plug Ethernet from the Google Wi-Fi's LAN, and turn MoCA off, you'll be fine, as the iPhone and TiVo will both be on the same network. If you use MoCA from the FiOS router, and then have the iPhone behind the Google Wi-Fi router, it will most likely not work through a NAT router. OP can ignore my reply and sit there wondering why the iPhone can't see the TiVo. Everything else will work fine from two different networks, since they both have internet access. You clearly don't have a complete grasp on this situation. Ethernet from the ONT to the Google Wi-Fi would be ideal. All newer FiOS setups use Ethernet from the ONT to the router, MoCA WAN is limited to 75/75 or with a specific ONT, 150/150 I believe. No. You can't use the G1100 as a MoCA WAN bridge AND a MoCA LAN bridge. It's one or the other. If you use it as a MoCA WAN bridge, it's no longer a router, you lose the MoCA LAN functionality, and you lose the Wi-Fi. That's all fine if you just want to provide Ethernet to your own router, and use your own networking technologies (including potentially a MoCA LAN adapter downstream of your own router). Because it can't do MoCA WAN bridging and MoCA LAN bridging at the same time. You could use Frontier's little MoCA adapter there, or another FiOS router for the WAN bridge, and then use the original FiOS router as a MoCA LAN bridge downstream of the router. I'd probably use the newer router as the WAN bridge, and buy an older revision Actiontec router for a MoCA LAN bridge, since that's a less critical function. If you create the MoCA LAN network with the TiVo by feeding it Ethernet downstream of the Google WiFi router, that is fine. Then use the FiOS router as a MoCA WAN bridge which will disable the router, Wi-Fi and MoCA LAN functionality. If the TiVos are connected via Ethernet to the LAN side of the Google Wi-Fi router, they will be on the Google Wi-Fi's LAN. The only thing the Verizon router would be doing is converting MoCA WAN to Ethernet for WAN access, serving the same function in the network topology as a cable modem, even though it's a totally different technology. What? You can't use a G1100 for both MoCA WAN and MoCA LAN when using a third party router. You could use two G1100s, one as a MoCA WAN bridge, and one as a MoCA LAN bridge.
