I have 1 hopper and 3 Joeys. In the last few days I've been having problems with my internet connection. I've also noticed that when the internet connection goes down, the hopper and joeys seem to lose their connection. Every time I've had an internet problem, I have to reset the hopper before the Joeys can connect to it. This confuses me because I thought they were connected through MOCA over my coax, not over my home ethernet/wireless network. I thought the internet was just used to push on -demand content. What else is it used for? Thanks!
