I am thinking of getting a sling box for my 722k through Dish. Couple of questions. I don't have an internet connection to my 722K right now. If I get a wireless adapter through Dish, I think it connects to the USB port on the 722K. The sling box also needs a USB connection. Would I need a hub to go to the one port on the 722K? Also, once everything works, can I use my blackberry outside to check signal strength when tweaking the dish? Thanks for your guidance.
