I have a 2 Hopper, 2 Joey system installed. Each Joey links to a separate Hopper. When connected to Home Network with Wifi or HIC , after 5 minutes of watching, both Joeys go to black screen at the same time, whether watching live programming, DVR or On Demand. If I change channel, it comes back on for another 5 minutes then goes black again. If I disconnect system from home network, both Joeys work fine without interruption. Tried putting 1 Hopper and 1 Joey each on their own Dish and solo node but problem still happens if connected to home network.
