I have been using a dish network satellite system with a Vip722K receiver and a DishComm modem since 2010. I have never had either a phone line or ethernet cable plugged into the receiver. Dish on demand was working with no issues until at least August 12th 2017(the last time I watched a movie). The next time I tried, it refused to work. I have dealt with four different customer service reps since then. The first was a chat with 'Melissa', who had no clue what a Dishcomm modem is, and when I told her I have been using Dish on demand for years with NO phone line or ethernet cable actually plugged in the the receiver, she responded with 'that's impossible' and disconnected. I had one more chat with someone who also did not know what I was talking about, but had the sense to give me a number to call. Called the number. Third person also did not know what a Dishcomm modem was, but went off to ask someone else. She came back with an answer. I was to get a Phonex easy jack. Problem solved - I thought. Got the easy jack, plugged it in, everything lit up exactly as it was supposed to. I managed - after some messing around with the installation/ analysis menus to get the caller ID working and a message that I had a connection. But still no Dish on demand. So, on to person number four, who told me that the Phonex easy jack was NOT a replacement for the Dishcom modem- that it only was used for caller id, but not for Dish on Demand, and that for that to work I had to have an internet connection. Of course, my internet ( also satellite) is installed on the opposite side of the house. We were trying to come up with some other solution when the call was dropped. So... any ideas??
