We've had several different Dish receivers over many years, but recently were upgraded to a Hopper and 2 Joeys. This worked very well for 2 weeks, and I decided to connect to our wireless router. No problem. The next day we woke up to a black screen. I went through the troubleshooting steps several times and finally got to watch TV last night for a couple of hours. This morning... black screen again. After an hour on the phone and lots more unplugging power/cables, resetting, waiting, etc. we finally got a picture again but within half an hour our Hopper was restarting itself again. No technician available until Saturday. Could a bad internet connection contribute to the restarts? We have terrible internet service where I live but I didn't think that it would affect things this way????
