Thanks guys for helping me with this. I'm going to be upgrading to a Premiere XL4 soon and I just want to make sure I have everything I need to set up a MOCA connection. I have FiOS with the MI424WR Rev. F Router in my basement. The Tivo will be on an upper floor where an ethernet cable cannot extend. My question is, in order to set up a MOCA network, do I need to buy the ECB2200? It seems that both the router and the Tivo provide Moca support. Is that all I need? Would the coax that goes into the Tivo go to the Moca jack only or do I need a splitter? Also, does anyone know if the future Tivo IP-STBs will work on this Moca network or will it be wireless? THANKS! THANKS !!!!
