I am going to switch from DTV to Dish and I have a few questions. I have cable at most locations in my home, but not all. I assume you have to go fully wired or wireless. In other words, you cannot mix wired and wireless? Second question, if I were to go fully wireless how well does the wireless system do on range? My DTV has struggled to reach some locations sporadically. Final question, buy or lease equipment? I heard Dish changed there lease structure recently that makes it more of an advantage to own. Thanks in advance.
