I live in a high rise apartment building and have had FIOS for a couple of years. When it was first installed we had the router (Actiontec MI424 rev I) installed in the master bedroom and the set-top box installed in the living room where our TV was. We have FIOS Digital Coice service on two phones that seem to connect directly to the existing phone wiring outlets in two separate bedrooms.
Now we have been upgraded to 100 Mbps Internet speed and they have mailed us the Quantum Gateway G1100 router. What I would like to do is install the new router in the living room so that my streaming TV devices (Fire TV, Chromecast Ultra) can connect directly to the router using the Ethernet port instead of using WiFi, since the WiFi signal in the living room is OK but not excellent (less strong than master bedroom).
My question is this. The router package includes a MOCA 2.0 splitter. Can I take the existing coax cable that goes into the set top box and plug it into the splitter and then connect one of the 2 splitter ports into the set top box and the other port into the new router and have it all work together - i.e. have the DVR and phone service work seamlessly?
