I've had 1 hopper and 1 joey for a few months. Dish installer installed the wifi adapter for me and I connected a Sling Adapter that I have from a friend. For awhile, all was good: I could watch Dish on my Android tablet and I could watch dish on my computer. About a week or two ago, I started having major connection problems. On the Android, I often get something like "weak or no video signal". Sometimes it works after/in spite of this and sometimes not. Tonight on my computer I am getting Error 33 and Error 44. I tried on a different network with both the Android and on a computer with similar results. I have unplugged the hopper numerous times and disconnected and reconnected the wifi adapter and Sling Adapter. Am I missing something? Did a Hopper "ungrade" trash the Sling compatibility? Thanks in advance!
