I am making drastic changes to my account to save some money. I returned my xfinity wifi modem and bought a Netgear wifi router. I also returned two "Joeys" keeping only two out of four tv's connected. the splitter thats in my basement still has all the coaxial cable running out of it to all the rooms where the tv's used to be. Afterwards I had trouble connecting to on demand and receiving youtube from the hopper. Now, after messing with the settings I get on demand and youtube but its really slow in connecting and buffering. Could the extra cables running to the no longer existing tv's be causing the lag in service? I also am using Comcast "Blast" with download speed is above 64Mbps and upload is around 11Mbps.
MoCA (your system technology) does normally have caps on ends of any cable that is not in use or on the node as the strength can "leak" if it does not have this. This should not effect it that much though IMO. Have you tried placing the Hopper in the router's DMZ?
