I recently had two hoppers and 3 joeys installed. One hopper has the wifi adapter, the other one does not. I planned on using the hopper with the wifi adapter to rent "On Demand" movies. I tried the other night, and at first, the movie looked like it was downloading, but never did. Another movie, that was supposedly free, had an error code come up that stated I didn't subscribe to the channel, whatever that was. I called tech support, and the broadband support person told me I have to have a wifi adapter in each and every hopper. Has anyone else had this issue? Or, do you have a wifi adapter in each and all hoppers?
