I have two TiVo Premiere 4 boxes running off MoCa network through an Actiontec MoCa Adapter ECB 2500c without any problem. I have a second Actiontec MoCa Adapter ECB 2500c. I am trying to connect this adapter to one of my wall coax connections upstairs to then connect via ethernet to a second router (for improved wi-fi as the main motorola modem/router is located in the basement and has poor signal upstairs). Is this even possible? Am I even making any sense? Thanks!
