I have a 722dvr and ordered a sling adapter and slinglink. The sling adapter never lit up nor was I able to view remotely on PC or android phone. Dish replaced my sling adapter, same problem. DVR shows that I have a broadband connection. I've called dish many times, last time they sent me a new 722DVR because they said my old one may not have had the right firmware to update my sling adapter. Needless to say I'm tired of wasting hours on the phone with technicians that have no clue what's wrong. Can you lend a hand?
