I'm a newbie to Dish network, I bought a house with a tenant in it already. The house has a dish and the prior owner had Dish Network that was working up until a couple days ago when they disconnected. The Tenant has Dish at another house and simply wants to relocate their Hopper to this house (seemed simple enough). They called Dish and relocated the address to this address and Dish said they'd be all set. When we plug it into the same plug that the old one was plugged into it says some 9999 message, then it says searching for signal with a gray bar that never moves and just hangs forever. The tech says they can't come out for at least three weeks. Does anyone have any suggestions? This seems like the simplest thing in the world. Unclear why it wouldn't "just work". Thanks!
