Current Configuration: 2 Hoppers (1st gen) 4 Joeys I have had the dual hopper system installed for about a year now and since day 1 I've had 2 joeys that will only see one hopper. System status shows bad MoCA on those Joey's. About a month ago I had a tech out to the house because of signal issues and he tried to fix this problem. I had already swapped Joeys and determined the problem stayed in the same rooms. The tech replaced all of the connectors, wall plates, cables from the wall to the boxes, etc. The only thing he didn't change was the actual cable in the walls. He concluded that because of the size of my system and the size of my house the problem was that the RG6 cable in the walls were not rated at 3GHz. (House was built in 2000.) He thinks this his was causing the communication issues. I have another tech coming back tomorrow because all of a sudden I am not seeing all of the satellites. While he's here I want to look at the communication issue again to see if it we can do anything about it. My current setup is as follows: Hopper A has a direct line from the Duo Node (in attic about 10ft from dish). Hopper B is run with a Tap that also connects Joey A. Joey B, C, and D are run off a 3-way splitter from the Duo Node Joey A&B can see both Hoppers. Joey C&D can only see Hopper A. Hopper A can see Hopper B and vice versa. I think there is a way we can run it where we take the Tap out of the equation. Since the Hopper behind the Tap is the only that the Joeys are having problems seeing, do you think this might fix my problem? Does anyone else with a 2 hopper/ 4 Joey system have problems like this? Any other ideas before the tech comes out? Thanks!
