Fios Router on Comcast (Moca)

My apologies if this has been covered before but, I don't see my specific question answered. Due to a problem I'm having with Fios concerning pricing I have switched to Comcast. They come on Wednesday to install. I've done some searching and it appears I can continue to use the Actiontec router if I plug the cable modem into the Wan port on the AcitonTec router. My question would be, can I still use the Moca Functionality of the router if I have the router configured to get to the internet (dhcp) though the Wan port. Does anyone else have experience with this? My hope is to plug in the cable modem find it works and then attach it to the wan port on the router and update the router settings to grab an ip though the wan port and not though coax as it currently does. Would I still be able to use the Moca on the router with this setup? Currently all four of my minis connect to the fios router and I'm hoping this will work.

Sorry if this is confusing. :up:
