I recently switched from Verizon FiOS to Comcast. When I was a Verizon customer I used MOCA adapters to extend my network out to the rest of my house instead of running CAT5. Last week the Comcast tech came through and switched our line over to Comcast and made sure TV and cable modem were up. Now via MOCA adapters I am no longer able to reach anything on my network or outside of it. I have tried hooking the adapters up with and with out splitters. My main cable line outside goes to a three way splitter before it enters my house so I tried hooking an adapter up there and testing and did not have any success. The ethernet light on the MOCA adapter lights up but I get nothing. The model of adapter I am using is Actiontect ECB2500C. Is there some kind of signal loss going on possibly? I am pretty green at this so please bare with me.
