Had my Hopper, Hopper w/sling and 2 Joey system installed this past Saturday. Everything worked beautifully until this morning when both Joeys lost visibility to the hopper w/sling. They could see the regular hopper fine. The first thing I tried was resetting the network/connections in the broadband menu from the problem receiver. This did regain visibility to the hopper w/sling...but 5 minutes later the Joey's lost communication to this receiver again. What is the proper way to reset the MOCA network? Is this something that typically needs to be done every few days??
