I just bought another house and Dish can out and installed a new Dish 1000, DPP44 and a power inserter for my 411. I was down stairs working in my theater and had to unplug my 622. The 411 lost total signal, did check switch, could not find anything. Rebooted and repeated twice. Tried 411 without power inserter, no go. Went down stairs, plugged the 622 back in and tada, all was fine again. What the #%$# is up with that? Can anyone enlighten me?
