I read through some old threads, but none seemed to address my issue. I just got a new Premier 4. I connected the MOCA ECB to my network and cable modem per Tivo's guide at http://www.tivo.com/mytivo/howto/moca.html?WT.z_links=moca_vanity. I get no COAX light. I did some checking, and changed the ECB installation so it was split off the wall jack and not in line between the jack and modem. Still no COAX light. Am I doing something wrong? Is there something on the Tivo I need to activate? It was working on my wireless with a G adapter, and I removed the G adapter, no go.
